Safety advisory for working with Cryo.s'"
Cryo.s'* tubes are intended for sample storage exclusively in the gas phase over liquid nitrogen or in freezers! lf Cryo.s* are stored in the liquid phase, nitrogen can seep into the tubes. Then upon thawing the vaporising nitrogencan generate high pressure, ultimately resulting in an explosion, as well as the release of any infectious material. Always take appropriate personal safety measures when working with Cryo.srM, including wearing safety clothing, using goggles and working at a safety laboratory bench. When undertaking cryogenic preservation. Cryo.s" must be evenly exposed to freezing temperatures. Uneven temperature exposures can cause formation of ice plugs (i,e. at tube iop) that inhibit the expansion of freezing liquid (i.e. at tube bottom), resulting in dangerous high pressure and subsequent harm or damage of tubes. Never exceed maximum working volumes
