Conductivity Calibration Solutions, Hanna

Made of Polypropylene

Designed for storing biological material, human or animal cells, at temperatures as low as -190°C. A silicone seal between the cap and the tube ensures a positive leakproof seal at all temperatures. A 1.25 turn of the cap is sufficient to seal the vial. Closure and tubes are both manufactured of polypropylene having the same coefficient of expansion, which ensures an equally secure seal both at room temperature and at low cryogenic temperatures. Tubes have a white marking area, can be color coded with a CAPINSERT (TM), and are compatible with most storage systems. Sterilized by gamma irradiation and packaged in unique tamperproof, resealable, safety-lock bags of 100.
