These popular conical-bottom centrifuge tubes are made of ultra-clear polypropylene copolymer. They feature printed graduations and smooth inner walls for easy filling and sample preparation. Printed writing area on side allows for permanent coding. Autoclavable at 122°C (251.6°F). Freezable to –90°C (–130°F).
(P.S. For those who are wondering the difference in these and our GeneMate tubes here is our observation. The GeneMate tubes are a cheaper variety of tubes. The VWR tubes preform better when freezing and at higher centrifugation speeds above 15,000G. These tubes are a great disposable tube for regular lab use and semen processing at normal centrifugation speeds)
