Why Is Glycerol Added To Cryogenic Freezing Plate

Cryogenic freezing plays a vital role in preserving bacterial cultures, scientific specimens, and medical samples. Among the many substances used to facilitate cryopreservation, glycerol stands out as a critical agent. Understanding the role of glycerol in cryogenic freezing helps unlock its effectiveness in maintaining the viability of delicate biological samples. This article delves into the mechanisms of glycerol in freezing plates, its applications, and its relationship to Commercial refrigerator systems, which provide essential storage solutions for cryogenically preserved materials.

The Role of Glycerol in Cryogenic Freezing

Preventing Ice Crystal Formation

One of the main reasons glycerol is used in cryogenic freezing is its ability to prevent ice crystal formation. Ice crystals can puncture cell membranes, leading to cell death and compromising the sample's integrity. Glycerol acts as a cryoprotectant by lowering the freezing point of water and reducing the rate at which ice crystals grow.

Stabilizing Cellular Structures

Glycerol interacts with cellular components to stabilize their structure during the freezing process. This protective layer preserves cell viability, ensuring that samples can be reactivated after thawing.

Facilitating Bacterial Preservation

In bacterial culture preservation, glycerol is commonly mixed with culture broth to ensure uniform freezing and storage. The mixture is often stored in sterile tubes, such as those used in Commercial Freezer systems, where precise temperature regulation ensures long-term viability.

Protocol for Cryogenic Freezing with Glycerol

1. Preparation of Glycerol Solution:

• A typical glycerol solution consists of 30% glycerol mixed with sterile water.

• Sterilization is achieved by autoclaving at 121°C for 15 minutes. This step is crucial for avoiding contamination.

2. Mixing with Bacterial Culture:

• Equal volumes of the glycerol solution and bacterial culture are mixed in sterile tubes, such as those stored in Undercounter Refrigerators.

3. Storage in Cryogenic Freezers:

• The prepared tubes are placed in cryogenic freezers or Walk-In Refrigerators and Freezers, ensuring consistent ultra-low temperatures.

4. Reactivation of Bacteria:

• Frozen bacteria can be reactivated by retrieving a portion of the frozen sample without thawing the entire tube, which reduces the risk of cellular damage.

Applications of Glycerol in Commercial Settings

Use in Laboratories and Research Facilities

Cryogenic freezing using glycerol is a standard practice in microbiology and biotechnology. Samples are typically stored in Commercial Fridges & Freezers, including Medical Freezers, which are designed to maintain precise temperatures for sensitive biological materials.

Application in Food Industry

In the food industry, Display Fridges and Meat Counters equipped with cryogenic storage capabilities ensure the long-term preservation of perishable items. While glycerol is not directly used in these applications, the same principles of cryogenic freezing are applied to preserve freshness and quality.

Role in the Pharmaceutical Sector

Pharmaceutical companies use cryogenic freezing for preserving vaccines, enzymes, and other medical products. Portable Freezers and Combi Wall Freezers are often employed for transporting these sensitive materials.

Commercial Refrigerators: Essential for Cryogenic Storage
