Light Insertion Force
FlexFit® sealing technology requires minimal insertion force to generate consistent seals that users can trust with every tip.

Light Ejection
No matter how tips are applied, xTIP4™ pipette tips will always eject at the same light force. The StarStop® feature works with LTS-style pipettes to create a strong seal in the same location, every time.

Low Binding
Biotix low retention technology reduces the amount of sample lost in the tip when pipetting. Great for use with loading dyes, proteins, and DNA to increase an experiment's accuracy and yield.

Clean Delivery
These tips are engineered with the Blade® ratio to reduce hanging droplet formation when dispensing a sample. This limits the need for tip touch off on plate wells or tubes, saving time and reagent.
