Freezer Racking Solutions for Laboratory Freezers


Have you ever had trouble locating a sample that you need from your lab freezer? Are you struggling to maintain your freezer temperature because of frequent door openings? Freezer racking is the solution. Freezer racks will help you to optimise space, keep track of your samples so they are easily accessible, and hold the freezer temperature more effectively.

In this article we will discuss the benefits of putting a freezer racking system in place, the different types available, and the cryogenic freezer racking that Froilabo has to offer.

What is Freezer Racking?

Laboratory freezer racking is designed to organise and safely store biological samples or other frozen materials in chest and upright freezers, deep freezers, and ultra-low temperature freezers. They are designed to make the most efficient use of space and are a durable and long-lasting solution to freezer organisation.

Freezer racks are commonly made from materials that are able to withstand ultra low temperatures such as stainless steel, non-corrosive aluminium, clear acrylic, or polycarbonate. They are designed with separate compartments to enable the storage of individual boxes, conical tubes, vials and other storage devices found in laboratory applications. This enables the clear labelling and identification of samples, while also providing safety and security for long-term storage.

What are the Benefits of Freezer Racking?

There are numerous benefits of using freezer racking for sample storage in your laboratory freezer.

  1. Make the most efficient use of freezer space – optimise space to store as much as possible within your freezer.
  2. Organise and categorise freezer space – create different sections for different applications which can be clearly labelled, for easy identification and location of samples.
  3. Allocate space – when multiple different people are using the same lab freezer, space can be easily allocated to each member respectively.
  4. Reduce temperature rises during door openings – studies have shown that the use of racking can reduce temperature rises during door openings and increase the warm up times.
  5. Hold the internal temperature if the freezer is 100% racked it will hold the overall required temperature more precisely.
