Sterile 50 mL polystyrene serological pipette with 1 mL graduations, purple color coding and individual paper/plastic or plastic-film wrapping. E-beam irradiated to SAL 10−6; RNase/DNase free, human-DNA free, non-cytotoxic and non-pyrogenic.
Puretest 50 mL serological pipettes are manufactured from clear, 100% virgin GPPS and use high-contrast, bidirectional graduations for measured aspiration and dispensing. The purple color code supports rapid capacity identification, while individual wrapping supports aseptic laboratory handling.
The transparent barrel supports meniscus inspection, while the tapered tip promotes controlled delivery into common laboratory vessels. Reverse graduations help operators estimate the liquid remaining during serial dispensing. The controller end is designed for use with compatible manual or electronic pipette controllers; fit should be confirmed for the intended controller model and workflow.
