A small amount of liquid can stay inside a pipette tip after dispensing. For water and routine buffers, that usually does not cause a problem. But the loss matters more when you are working with expensive reagents, viscous samples, detergent-containing solutions, or very small volumes.
Low retention pipette tips are designed to leave less liquid behind on the inside of the tip. They can improve sample recovery when the liquid tends to wet or coat polypropylene, or when even a fraction of a microliter matters.
They are not necessary for every pipetting task. Their value depends on the liquid, the transfer volume, the sample value, the pipette-tip fit, and the technique being used.
A “low-retention” label alone does not establish how two products will perform in your workflow. Look at the liquid, transfer volume, and test conditions behind each performance claim.
Quick answer
Evaluate low-retention pipette tips when residue affects sample recovery, particularly with detergent-containing solutions, viscous liquids, valuable reagents, or small-volume transfers. Standard tips remain a practical option when your current method meets its requirements.
What Are Low-Retention Pipette Tips?
Most disposable pipette tips are made from polypropylene. It is a good material for routine liquid handling, but some liquids still spread across the inner wall and leave a film or droplets after dispensing.
A low retention pipette tip is designed to reduce that wetting. Manufacturers may use different materials, molding processes, or surface technologies to make the inside of the tip more liquid-repellent.
The goal is simple: help more of the aspirated sample leave the tip.
In practice, low retention tips are most useful when the amount left behind affects sample recovery, delivered volume, or reagent cost.
How Do Low-Retention Pipette Tips Reduce Residual Liquid?
Liquid behavior inside a tip depends on both the liquid and the plastic surface.
Low-surface-tension liquids tend to spread more easily across polypropylene. Detergent-containing solutions are a common example. Instead of moving as a clean liquid column, some of the sample may remain as a thin film on the tip wall. See the Sartorius application note on low-retention tips and detergent-containing liquids for an example of testing under defined conditions.
Viscous liquids create a different problem. Glycerol-containing solutions, serum, and concentrated protein samples move more slowly. They may also leave more residue after dispensing.
Low-retention surfaces reduce wetting and adhesion, which can help more liquid leave the tip.
Residual liquid does not only collect near the narrow opening. It can remain along the internal wall as well. That is why the surface of the full sample-contact area can matter.
Low-Retention vs Low-Binding Pipette Tips: What's the Difference?
The terms sound similar, but they do not describe exactly the same issue.
Low retention refers mainly to liquid that remains inside the tip after dispensing.
Low binding pipette tips are designed to reduce adsorption of sample molecules, such as proteins or nucleic acids, to the plastic surface.
A tip may help with both problems, but a low-retention claim does not automatically mean the tip has also been validated for low molecular binding.
If protein or nucleic-acid adsorption is important to your assay, check what the manufacturer has actually tested.
When Should You Use Low-Retention Pipette Tips?
Low-retention tips make the most sense when sample left inside the tip has a real experimental or cost impact.
Precious or Expensive Reagents
A fraction of a microliter may not sound like much. That changes when the liquid contains an expensive enzyme, antibody, master mix, purified protein, sequencing reagent, or limited biological sample.
A single transfer may not create meaningful waste. But across dozens or hundreds of pipetting steps, small losses can add up.
They are also useful when the sample is difficult to replace. In those cases, recovering more of the liquid may matter more than the small added cost of the tip.
Viscous Liquids
Glycerol-containing solutions are a common example.
Because they move slowly, viscous samples can be harder to aspirate and dispense cleanly. Serum and concentrated protein solutions may behave in a similar way.
A low-retention surface can help reduce the film left behind, but tip choice is only one part of the workflow. Pipetting speed, technique, and tip geometry can also affect performance.
For very difficult samples, wide-bore tips or other pipetting approaches may also be worth considering.
Detergent- and Surfactant-Containing Solutions
Detergents and surfactants reduce surface tension. This makes the liquid more likely to spread across a standard polypropylene surface.
Common laboratory examples include SDS and Tween-type surfactants.
When a liquid leaves a visible film inside a standard tip, a low-retention surface may improve recovery by reducing that wetting.
This is one of the clearest situations where low-retention performance can make a practical difference.
Automated or Repetitive Liquid Handling
A tiny loss becomes more important when the same transfer happens hundreds or thousands of times.
In automated liquid handling, repeated residual volume can increase reagent use and may contribute to differences across wells or plates.
Low-retention tips can help with recovery, but they do not replace proper method setup.
- tip fit and sealing
- volume range
- liquid class or dispensing settings
- platform compatibility
- the correct aspiration and dispense parameters
When Are Low-Retention Pipette Tips Not Necessary?
Standard tips are usually enough for many routine workflows.
Examples include water, standard aqueous buffers, straightforward dilutions, moderate or larger transfers, and inexpensive reagents where small residual losses do not matter.
It usually makes more sense to choose low-retention tips for specific workflows instead of switching the entire lab.
If retained liquid is not affecting recovery, delivered volume, or reagent cost, the extra cost may not provide much practical value.
Why Residual Liquid Matters More at Small Pipetting Volumes
A small amount left in the tip matters more when the intended transfer is also small.
Illustrative calculation: assume that 0.8 µL remains inside a tip after dispensing. This is a hypothetical example, not a measured result for standard tips or Direct2Lab products.
| Intended transfer | Assumed residue | Residue as a share of transfer |
|---|---|---|
| 10 µL | 0.8 µL | 8% |
| 100 µL | 0.8 µL | 0.8% |
Calculation: residual volume ÷ intended transfer volume × 100. For the 10 µL example: 0.8 µL ÷ 10 µL × 100 = 8%.
Actual retention depends on liquid chemistry, tip design, transfer volume, pipetting technique, and the test method. The practical implication is to evaluate recovery at the volume you actually use.

Low-Retention vs Standard Pipette Tips: What's the Difference?
Low-retention tips are not automatically more accurate than standard tips in every workflow. Their main advantage appears when liquid left inside a standard tip becomes a meaningful source of sample loss.
| Selection factor | Standard pipette tips | Low-retention pipette tips |
|---|---|---|
| Internal surface | Standard polypropylene surface | Designed to reduce wetting and residual liquid |
| Routine water and aqueous buffers | Often sufficient when the method meets its requirements | Additional benefit may be limited |
| Detergent-containing liquids | May retain a film on the tip wall | Worth evaluating for reduced wetting and improved recovery |
| Viscous liquids | May be difficult to aspirate and dispense cleanly | May help with residue; technique and tip geometry still matter |
| Small or valuable samples | Assess whether retained liquid affects the workflow | Evaluate whether recovered sample justifies any price difference |
| Fit, calibration, and technique | Must suit the pipette and method | The same requirements still apply |
Practical choice: use standard tips when they meet the workflow's requirements. Evaluate low-retention tips for liquids that are difficult to dispense cleanly or where sample recovery matters. This is an application-based recommendation, not a guarantee of improved assay results.
Compare Direct2Lab Low-Retention Tip Formats
If low-retention performance is worth evaluating, select packaging, filtration, and sterility separately. A low-retention surface does not by itself determine whether a tip is filtered, boxed, or supplied as a refill.
| Direct2Lab format | What to confirm | Product path |
|---|---|---|
| Boxed, sterile, low-retention, non-filter | Required volume range, pipette fit, and whether a non-filter format suits the method | View boxed low-retention tips |
| Stacked refill, sterile, low-retention, non-filter | Required volume range, pipette fit, and compatibility with the refill system | View stacked-refill low-retention tips |
If the workflow requires a different combination of filtration, sterility, or format, compare all Universal Pipette Tips before selecting a product.
Low-Retention vs Wide-Bore Pipette Tips
Low-retention and wide-bore tips solve different problems.
A low-retention tip helps reduce liquid left on the inner surface.
A wide-bore tip has a larger opening. This can reduce flow resistance and shear.
Wide-bore tips may be useful for delicate cells, high-molecular-weight DNA, very viscous materials, and samples that do not move easily through a narrow opening.
The two features can also be used together.
For example, a very viscous sample may benefit from a wider opening for easier flow and a low-retention surface for better sample recovery.
One feature does not replace the other.
How to Choose Low-Retention Pipette Tips for Your Workflow
The useful question is not simply, “Are low-retention tips better?”
A better question is: Will improved sample recovery make a meaningful difference in this workflow?
Start With the Liquid
Look at how the sample behaves.
Does it contain glycerol, detergent, surfactant, concentrated protein, or another component that makes it drain slowly or wet the tip wall?
If you regularly see droplets or a visible film left inside standard tips, low retention is worth evaluating.
Consider Transfer Volume
Small-volume transfers are more sensitive to residual liquid because even a tiny amount can represent a large percentage of the intended volume.
For low-volume work, ask whether the liquid left behind is large enough to affect recovery or downstream consistency.
Consider Sample Value
Cost matters differently when every microliter contains an expensive enzyme, antibody, sequencing reagent, or hard-to-replace biological sample.
In those cases, recovering a little more sample across many transfers may justify a higher consumable cost.
Check Pipette Compatibility
A good surface cannot compensate for poor tip fit.
Confirm the correct volume range, secure sealing, compatibility with the pipette, and automation compatibility when relevant.
Evaluate Filter, Sterility, and Other Requirements Separately
Low retention is only one tip feature.
A workflow may also require filtration, sterility, wide-bore geometry, or automation compatibility.
For example, low retention filter tips combine two separate functions: reduced liquid retention and a filter barrier.
A filter does not automatically make a tip low retention, and a low-retention tip does not automatically include a filter.
Choose each specification based on the workflow.
Compare Low-Retention Performance Claims Carefully
Low-retention tips can perform differently under the same test conditions. A manufacturer comparison from Sartorius explains why the label alone does not guarantee better performance than a standard tip.
Before comparing two products, check what liquid was tested, what volume was used, how residual liquid was measured, whether both products were tested under the same conditions, and whether the tip fits your pipette or automated system.
A result measured with one detergent at one volume should not be treated as a prediction for every sample.
How to Evaluate Low-Retention Pipette Tips Before Switching
A product label alone cannot show how a tip will perform with every liquid, volume, pipette, and technique. Before standardizing a low-retention tip, compare it with the tip currently used in the actual workflow.
- Use the real workflow liquid and volume. Water-only testing may not represent the behavior of a viscous, detergent-containing, or low-volume sample.
- Keep the pipetting setup consistent. Use the same pipette, operator, aspiration and dispensing technique, temperature conditions, and timing for both tip formats.
- Confirm fit before evaluating retention. Check for secure seating, leaks, inconsistent aspiration, difficult ejection, or movement between the tip and pipette.
- Compare outcomes that matter to the method. Depending on the procedure, this may include delivered mass or volume, visible film or droplets, recovery, variability across repeated transfers, and reagent consumption.
- Use repeated measurements. A single transfer cannot show whether an observed difference is consistent. Record the pipette, liquid, working volume, product SKU, lot, technique, and number of repeats.
- Apply a workflow-specific acceptance criterion. Decide in advance what improvement would justify a change in consumable cost or format. The result should support an internal qualification decision, not a universal ranking of products.

Frequently Asked Questions About Low-Retention Pipette Tips
Do Low-Retention Pipette Tips Improve Accuracy?
They can help when residual liquid is one of the reasons the delivered volume is inconsistent.
The benefit is most useful with difficult liquids and small-volume transfers.
They cannot correct poor technique, incorrect calibration, bad tip fit, or the wrong aspiration and dispensing settings.
Do You Need Low-Retention Tips for Water and Standard Buffers?
Usually not.
Standard tips are generally sufficient when water or an aqueous buffer dispenses cleanly and the small amount left behind does not affect the experiment.
Using low-retention tips only where they add value is often more economical.
Are Low-Retention and Low-Binding Pipette Tips the Same?
No.
Low retention mainly deals with liquid left inside the tip.
Low binding deals with sample molecules sticking to the plastic surface.
Some products may address both issues, but the claims should be checked separately.
Are Low-Retention Tips the Same as Wide-Bore Tips?
No.
Low-retention tips reduce liquid adhesion.
Wide-bore tips reduce flow resistance and shear by using a larger opening.
Some samples may benefit from both.
Are Low-Retention Pipette Tips Worth the Extra Cost?
They are more likely to be worth it when the reagent is expensive, the sample is difficult to replace, the liquid is hard to dispense cleanly, the transfer volume is small, or the workflow repeats the same transfer many times.
For routine aqueous work, standard tips may still be the better value.
The right choice depends on the cost and consequence of the sample left behind.
