Laboratory freezer racking

We can supply a huge variety of freezer racking, from standard cryobox freezer racks through to bespoke storage bins and cryoboxes. Please contact us to discuss your requirements in detail.

Why use freezer racking?

Organising stored samples with suitable ULT racking and an inventory management system can help laboratories to improve their energy efficiency and time management.

Firstly, using freezer storage racks along with inventory management should minimise door-opening times and reduce the ice-build up that can result. It also saves valuable time spent searching for stored samples and reagents.

Put simply: Knowing where the item you need is located saves time and energy!

Colour-coded freezer racking can be a great way for institutions to organise their samples. It allows more than one department to more easily share a ULT freezer rather than running two half-empty ones—again, offering energy-saving benefits. See below for more information on coloured freezer racks.

Types of freezer storage

We’ve outlined some of the options below, but please get in touch for more information or to request a quotation.

Horizontal freezer racks

Horizontal racks for ULT freezers allow users to make maximum use of the storage space in their upright ULT freezers.

  • Racks hold trays (for cryoboxes, microplates), divided trays or storage bins
  • Racks available for storing 15ml or 50ml centrifuge tubes
  • Aluminium or stainless steel versions


Front-access freezer racks offer convenient and quick access to stored items—only one tray needs to be removed in order to take out/locate an item in the freezer.

Side-access versions are available and are easily customisable for various sizes of cryoboxes. In addition to cryoboxes, they can also hold microtitre plates, and are ideally suited to long-term storage.

Freezer storage bins

Ideal for organising and safely storing any loose items within the freezer. Storage bins can be custom-made to any size.

  • Available in anodised aluminium or stainless steel
  • Choice of fold down handle or hand grip
  • Can be fitted with a handle on each end for easy transport
  • Label holder for clear inventory organisation
  • Standard sizes: 140mm wide and 280mm wide

Vertical ULT freezer racks

Vertical cold stores are available in many sizes and designs. They are ideal for organising and maximising storage within laboratory chest freezers.

Standard vertical freezer racks have either solid sides or a wrap-around body for increased strength. Holes located in the back of the racks allow cryoboxes to be pushed out.

  • Aluminium or stainless steel versions
  • Commonly used to store cryoboxes
  • Bespoke racks available to store microtitre plates, deep-well plates or centrifuge tubes
  • Space-efficient fold down handle to allow easy removal from the chest freezer
  • Fixed handle versions (handle fixed in upright position)
  • Identification labels available

Coloured racking

As described above, colour-coded racking can assist with freezer organisation and facilitate sharing. However, coloured freezer racking can also be used to highlight mission-critical or valuable samples that should be moved to a back-up unit as a priority, if the freezer fails.

  • Vibrant colours including: blue, red, purple, orange and green
  • Clearer visibility of your storage racks even when covered in ice/frost build up

Cryoboxes

Our customers can choose from a wide selection of cryoboxes in a variety of heights and configurations, with and without dividers, to suit various tubes and cryovials.

  • Cardboard, plastic (polypropylene or polycarbonate) and aluminium versions
  • Bespoke sizes available in aluminium
  • Several colour options in plastic and cardboard varieties
  • Cardboard cryoboxes (and glue) are recyclable and non-toxic

Vaccine storage

We can supply specially-developed racking to maximise storage of the Pfizer/BioNTech COVID-19 vaccine. Using such racks for storing the vaccines will help minimise the time the freezer door is open and will help maintain the temperature required to safely store the vaccine.

  • Aluminium or stainless steel versions
  • Racks available for all major ULT freezer brands
