Labcon ZAP™ Slik Aerosol Filter Universal Pipette Tips

ZAP™ Slik Aerosol filter Pipette Tips from Labcon combine the higher standard of ZAP™ filters with our own unique low retention pipette tips. These aerosol tips provide you with complete protection from sample carry-over at the same time they reduce sample retention. Incorporating a robotically inserted 10 um filter with a sponge-like porous pathway ZAP™ Slik tips have such a small pore they even block fluids in the unlikely event that you should over-pipette. And our SuperSlik®; polypropylene increases the hydrophobicity of tips surfaces, so they have up to 10 times less fluid retention.

ZAP™ Slik Aerosol Filter Pipette Tips have been proven in independent studies to block aerosol contamination. But unlike some leading brands of self-sealing aerosol resistant pipette tips they have no cellulose gum, toluene solvent, or colored dyes in the filter to mix with and contaminate your sample. Also, unlike self-sealing aerosol tips ZAP™ tips can be autoclaved in a steam autoclave. And ZAP™ tips will not wick fluids like cellulose filled aerosol resistant tips so you don't have to worry about how you hold your pipettor. Our ZAP™ tips in sterile racks, like all our other sterile products, receive valid sterilization processing compliant with ISO 11137. So unlike "pre-sterile" tips from other pipette tip suppliers you can use ZAP™ Slik tips for diagnostic and regulated procedures. And ZAP™ Slik tips are RoHS compliant, unlike other low retention tips, so you don't have to worry that additives will migrate into your sample.
