Controlled Rate Cryogenic Freezing Container Holds Eighteen Vials Featuring Heavy Duty Polycarbonate Jar And Hdpe Foam Insert For Steady Negative One Degree Cooling Rate Ideal For Zero Fuss Sample Preservation

Controlled rate cryo sample jar holding eighteen lab tubes
✔️ Durable case holding sample tubes during steady temperature drop phases

This controlled rate cryogenic freezing container helps you store biological specimens safely. You place it inside a standard minus eighty degree mechanical freezer to lock your cells in time. The slow cooling pace prevents damaging ice crystals from forming inside your precious samples.

✅ Translucent polycarbonate body features an opaque blue threaded lid that seals out moisture
✅ High density polyethylene foam wedges cushion eighteen point zero millimeter tubes
✅ Filled chamber using pure isopropyl alcohol pulls heat away during initial freezing
✅ Direct workspace arrangement fits standard point eight zero and two point zero milliliter vessels

💡 What factors determine optimal controlled rate freezing for sensitive laboratory specimens? A practical setup makes it pretty handy for your daily workflow when precision matters most. You get steady thermal shifts that keep your cultures viable. - Gradual heat extraction avoids rapid water crystallization that tears apart fragile cellular walls - Uniform fluid density distributes thermal loads evenly across every individual tube position - Secure vessel placement eliminates risky manual handling that exposes fragile cultures to ambient warmth
