Easy-to-use unit provides “controlled rate” freezing samples at approximately -1°C per minute, which is needed to prevent lethal intracellular freezing and successful cryopreservation. Prior to inserting vials, the unit should be filled with 250ml of 100% isopropyl alcohol. Once the samples have been inserted the unit should be placed in a -80°C mechanical freezer. Clear...

Can be used for up to 45 minutes to rapidly and repeatedly chill biological samples for use in molecular biology. Applications such as ethanol precipitation of DNA/RNA samples are made easy, eliminating the inconvenience of traditional dry ice and alcohol baths. After storing the polycarbonate cooler overnight at -20ºC, inserted samples freeze within a few minutes. Use...

Durable polycarbonate boxes are ideal for compact storage of cell stocks in 1.2, 2.0 or 5.0ml cryogenic vials. F18849-0001 can be used with Cryo Tower Storage Systems (F18853-0004 and F18853-0008) to save valuable bench space. Can be used in temperatures from 196ºC to +121ºC Clear lids can be written on with permanent markers and have a printed grid for easy inventory Keyed...
