Labcon ZAP™ Slik Aerosol Filter Pipette Tips - Hinged Lid

Each style of ZAP™ SLIK Tips is designed from the beginning to fit precisely the range of pipettors listed in the fit charts. We carefully inspect the fitting with the actual pipettors, not just with measuring gauges. This means you won’t have to worry about leaking Tips and you don’t have to use extra force to mount these Tips.
 

ZAP™ SLIK tips feature a pure 10 uM pore size patented filter without any dyes or additives. The pores on this filter are 100% smaller than those in other aerosol tip brands. A smaller pore guarantees that your pipettor barrel will be kept clean of DNA, radionucleotides, and other contaminants. And this filter works to block fluids without any contaminants in the filter so you never have to worry that your work will be spoiled if your sample contacts the filter.

Real World Lab Tested

Labcon® ZAP™ Slik Tips are developed using their own in-house laboratory and tested on real pipettors. they don't use "pin" gauges or other unrealistic testing methods.

Quality Certification

Certificates are on file by lot number for all test results and available from the certificates page.

Virgin Resin

Only 100% Medical Grade virgin polypropylene resins are used in ZAP™ Slik Tips. No recycled plastics or commodity-grade resins.

FDA Registered Manufacturing

Labcon® is the only major pipet tip supplier to be registered by the U.S. Food and Drug Administration (FDA)

Sustainable Product Design

Like all Labcon® products, Eclipse tips are designed from the beginning with sustainability in mind. These products go far beyond simple recycling to offer real Earth Friendly® solutions.
