Low-retention pipette tips for difficult liquids
When low-bind surfaces help with proteins, enzymes, detergents, viscous reagents and precious samples.
Low-retention tips reduce liquid film on the inside wall of the tip, which can improve recovery in sticky, viscous or low-volume transfers.
Use them when residue changes the result
Low-retention tips are most helpful when a visible or invisible film remains inside a standard polypropylene tip after dispensing.
Common use cases include glycerol-rich mixes, protein solutions, enzyme stocks, detergents, master mixes and samples where every microlitre matters.
Do not confuse low retention with sterile
Low retention describes the surface behaviour of the tip. It does not automatically mean filtered, sterile or RNase/DNase-free unless the SKU also carries those claims.
For sensitive workflows, choose the combination explicitly: low-retention plus filtered, low-retention plus sterile, or low-retention plus both.
Technique still matters
Pre-wetting the tip, using steady aspiration, keeping a consistent immersion depth and avoiding bubbles can matter as much as the surface treatment.
When a method is validated, change one variable at a time and document the switch from standard to low-retention tips.
Checklist.
Choose low retention for sticky, viscous or expensive samples.
Check whether the SKU is also filtered or sterile when needed.
Pre-wet tips for difficult liquids if the method allows it.
Document any tip change in validated methods.
Compare recovery before standardizing a new tip across a team.
