Cool and Collected: Essentials of Lab Freezer Organization

In scientific research, where precision and accuracy are key, lab freezer organization is crucial and non-negotiable. The utility of a well-organized freezer extends beyond convenience, with the implications of disorder ranging from spilled samples to failed analysis. In this article, we explain the significance of lab freezer organization and explore the tools, best practices, and benefits associated with this practice.

Why is Lab Freezer Organization Crucial?

It comes down to the value of samples and the efficiency of the lab.

Scientific research hinges on the value of its samples. These samples are the products of painstaking experiments and often hold the key to groundbreaking discoveries. Some are so unique that they cannot be replicated. The loss of such samples due to haphazard freezer organization can not only set back research but also result in substantial financial costs.

Efficiency and speed are the lifeblood of any scientific laboratory. In a disorganized freezer, researchers waste valuable time searching for samples, leading to operational inefficiencies. A well-organized freezer, on the other hand, ensures quick access to samples, minimizes downtime, and enhances productivity.

Consequences of Disorganized Freezers

Disorganization within lab freezers can have expensive consequences, potentially derailing research efforts. Repercussions include losing context and audit trails of important samples, or losing samples completely. One of the most painful points to experience the consequences of freezer chaos is in analysis, when information or the sample itself is lost and the analysis must exclude potentially vital information.

Freezer Accidents

Good organization also ensures accidentally incurred consequences are kept to a minimum. Samples that cannot be thawed even a little bit are able to be kept away from the door, where temperature fluctuations are highest. Other concerns with cluttered freezers include hazardous chemicals potentially spilling, creating unsafe working environments and contaminating important or rare samples.


Essential Supplies for Organizing Sample Inventory

To maintain a well-organized lab freezer, several indispensable tools come into play, each serving a specific purpose:

  • Freezer Racks: These racks serve as the backbone of freezer organization. They hold samples in tubes in an organized manner, optimizing storage space and facilitating easy retrieval.
  • Labels and Markers: Clear and concise labeling is essential for identifying the contents of each container or assigning a name to a storage vessel. Labels can be printed directly on the vessel, attached as printed stickers, or applied using tape and markers. Printed labels have the option to include barcodes, allowing lab personnel to access metadata rapidly.
  • Containers and Bins: Containers and bins play a pivotal role in categorizing and organizing various items within the freezer. They prevent clutter and ensure that samples are stored neatly.
  • Freezer Management Software: Modern technology comes to the aid of laboratory organizations with specialized software. Freezer management software offers a digital inventory of samples, simplifying tracking, retrieval, and real-time data updates. It can also map out your available freezers and storage racks down to the sample level, making finding specific samples faster and more efficient. It’s a vital tool for managing sample and lab inventory information.

Best Practices for Long-term Lab Freezer Organization

Organizational efforts should be continuous to avoid a last-minute scramble on defrost day. Consider these tips for long-term maintenance, well after the initial clean out and cleanup process:

  • Choose Rectangular Containers: In rectangular refrigerators, rectangular containers stack more efficiently than circular ones, maximizing space usage. This might seem basic, but maximizing storage usage and ensuring containers can support each other can make a big difference in the long term organization of a freezer.
  • Regular Inventory Checks and Audits: Periodically review and audit your freezer inventory to maintain order and identify any missing or misplaced items.
  • Maintain Documentation: Keep meticulous records of sample locations, changes, and additions, and emphasize the importance of placing freezer items back in their recorded location.
  • User Training: Ensure all laboratory users are well-versed in the software and procedures established for maintaining the organized freezer. Choose user-friendly systems to ease the transition, and get members to participate in the process.


Easy Steps to Organize and Clean-up a Lab Freezer

When you start out with a new system, take these steps to prepare your lab for long term organization.

  • Remove Outdated Samples: Regularly purge outdated or unnecessary samples to create room for new ones and maintain an efficient storage system.
  • Categorize the Samples: Group similar samples together to streamline access and retrieval.
  • Use Labels Effectively: Ensure each sample is labeled accurately and comprehensively for easy identification. This includes using labels designed not to degrade and peel off in the freezer. Consider easy-to-read printed and barcoded label options too.
  • Plan Ahead for Regular Maintenance: Once you’ve purged, categorized, and labelled your samples, and you close the freezer door, remember to sit down and plan ahead. Schedule routine freezer maintenance, cleaning, and defrosting now to prevent chaos and ensure a smoothly running freezer. Putting notices up now and adding calendar reminders helps every user stay aware of these maintenance deadlines.


How Can Freezer Management Software Help?

Freezer management software has a lot of helpful features available, although not every program has everything you may need or want. Some programs, like Sample Manager, have a variety of functions that seamlessly integrate freezer management with samples and inventory.

Essential Features

  • Customizable storage containers
  • Complete virtual map of freezer spaces
  • Real-time inventory updates
  • Manual action details such as freeze/thaw counts, volume, etc
  • Sample lineage and freezer context trails
  • Queryable metadata

Freezer organization is not just a function of neatness. Standardized processes and practices help keep it all together, and good organization shows a clean picture of what’s going on from a high level down to a single sample. The right freezer management software fills in the gaps from neatness to order.
