1.5mL Screw Cap Freezing Tubes, 500/unit

Our microcentrifuge tubes offer exceptional sample integrity and ease of use in long-term, extreme-temperature storage as low as - 196°C. Screw closure seals without gasket or O-ring, eliminating the risk of contamination and improving your one-handed aseptic technique. Comes in resealable bags for storage. Tubes stand without rack or holder. 

Note: Do not use these for storage in the liquid phase of liquid nitrogen unless they're correctly sealed. Such usage may cause liquefied nitrogen to be trapped inside the tube, resulting in pressure build-up and potential explosion.
