Made of high quality 100% pure virgin medical grade polypropylene so you won’t find recycled plastics in our tips. Every lot is lab tested and certified free of detectable Nuclease (Rnase/Dnase), Endotoxin (pyrogen) contamination, and certified to U.S.P. results. Resins are pre-tested for metal contamination. All our tips in racks are packed in teal racks. These racks are made of polypropylene and are autoclavable repeatedly. They have sturdy latch hinges that won’t come apart like lesser quality tip racks and a special snap lock designed so that it will not catch on your gloves.
Aerosol tips provide you with complete protection from sample carry-over. Incorporating a robotically inserted 10 μm filter with a sponge-like porous pathway. The tips have a small pore that blocks fluids in the unlikely event that you should over pipet. Proven in independent studies to block aerosol contamination but unlike some leading brands of self-sealing aerosol resistant pipet 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 our tips can be autoclaved in a steam autoclave. And they will not wick fluids like cellulose-filled aerosol resistant tips so you don’t have to worry about how you hold your pipettor.
