Optimising Storage in Cryopreservation Units

Efficient use of storage space in cryopreservation units is crucial for maintaining the integrity and accessibility of biological samples. The system offered for optimising storage in LN2 (liquid nitrogen) tanks helps laboratories make the most of their storage capacity, while ensuring easy identification and retrieval of samples. Here’s how the process works:

1. Diminution of the LN2 Tanks' Footprint
   A key feature of this system is its ability to reduce the footprint of LN2 tanks. By optimising the arrangement of storage units within the tank, more samples can be stored in less space. This compact storage solution maximises the number of samples without compromising accessibility.

2. Optimisation Through Mapping
   Optimising storage is not just about reducing the size of the tanks; it’s also about mapping the storage units to ensure they are used efficiently. By carefully organising and categorising samples, each one has a designated space, making retrieval straightforward and reducing the risk of misplacement. Modular storage units, such as goblets and visotubes, can be uniquely identified, enabling labs to maximise the use of available space and maintain an organised system for quick sample retrieval.

3. Customisable Goblet Storage for Patient Samples
   The system offers a versatile and customisable solution for storing patient samples within LN2 tanks. Users can design their own goblet storage units, creating unique sub-divisions that fit their specific needs. These units help ensure that each sample, or group of samples, has its own space in the storage tank.

By using colour-coded goblets, labs can easily organise and differentiate between patient samples. Each goblet can hold a number of visotubes, which are also colour-coded for further categorisation, making it easy to quickly identify the right sample when needed.

1. Tips for Efficient Storage Organisation To fully optimise storage in LN2 tanks, here are a few tips to help laboratories efficiently organise their cryopreservation units:

Tip 1: Create Concentric Circles for Canister Identification
• Create concentric circles for a unique identification for each canister.
• Use the colourful flags on the lifters with the possibility to write a letter on it.
• Use a single colour goblet per floor + write the same letter and the number of floor (ex: A1-A2-A3 etc.)
"Goblet of interest has been found!"

Tip 2: Use Daisy Goblets for Colour-Coded Visotubes
• In each daisy goblet = 1 unique coloured visotube (=12 unique visotubes).
"Visotubes of interest have been found!"

Tip 3: Triple Check Process for Sample Confirmation
• 1st check: colour coding of the straw.
• 2nd check: ID patient (with the cryolabels or MAPI printer).
• 3rd check: Witnessing software to confirm the selected sample.
"Sample of the patient has been found and confirmed!"

1. Infinite Possibilities for Sample Grouping The system provides flexibility for designing custom storage solutions tailored to the specific needs of the laboratory. Whether organising by patient group, sample type, or other criteria, the modular design offers infinite possibilities for efficient and organised sample storage. The goal is to ensure that every sample is easily accessible while making the most out of the available storage space.
