Kit for microorganism preservation Protect Multipurpose

Protect is a system that allows the cryo-preservation of bacteria, yeasts and fungi in a freezer at -20, -70, -80°C or in liquid nitrogen.

The creation of stock libraries is made easy and fast for all microorganisms, including the most demanding ones (database available with historical data on temperatures and storage duration).


Protect consists of cryogenic tubes containing:

  • colored porous ceramic beads, on whose surface microorganisms easily adhere
  • nourishing solution with glycerol, which prevents cell damage caused by cold
  • the test tubes have caps of the same color as the beads; the color has the purpose of coding the contents of the test tube in the library
  • gamma ray sterilization guarantees a SAL 10^-6.
