To maximize the viability of sperm cells, the critical temperature lowering stages must be carefully controlled. The initiation of ice crystal formation – nucleation or seeding – must be strictly controlled to ensure optimal crystal size and shape. Digitcool’s perfect airtightness and insulation, its power and its constant regulation of data parameters, allow the user to determine optimal freezing curves, and provide simple and accurate repetition. Temperatures are constantly and precisely monitored by two separate probes (chamber and product) to ensure that the main freezing stages are perfectly controlled.

Digitcool freezers are used for the cryopreservation of any biological product (semen, plasma, blood cells, tissue, gametes, etc.).

Sample capacity: 5250 mini straws or 3000 medium straws

The chamber contains 30 freezing racks

Ideal with Pressurized 120 liter LN2 container with hose and wheels

Controlled deep freezing

Respected fundamental thermodynamic principles to preserve the integrity of gametes.

Enhances your Standard Operating Procedures

Stainless steel Digitcool freezers are fully programmable and easy to disinfect.
