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. Tips are racked and packed in a teal rack. 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.
Our transfer pipets are made of polyethylene and are commonly used to transfer blood samples from tubes and vials. These disposable transfer pipets are generally used to draw and dispense liquids in drop sizes.
