Lab Cold Storage 101: Finding the Right Refrigerator or Freezer for Your Samples

Whether you’re storing reagents, vaccines, plasma, or temperature-sensitive standards, the wrong cold storage unit can put your samples—and your results—at risk. GMICore carries purpose-built lab and pharmacy refrigeration, from compact undercounter units to ultra-low temperature freezers reaching -86°C, so you can match the equipment to the application instead of settling for whatever fits in the break room.

Here’s a quick breakdown of what’s available and how to choose.

Laboratory Refrigerators

Our lab refrigerator lineup covers general-purpose storage as well as application-specific units, including:

• General-purpose lab refrigerators for reagents, media, and everyday sample storage
• Pharmacy and vaccine refrigerators built for temperature stability and organized, easy-access shelving
• Flammable-storage refrigerators with non-sparking components that meet NFPA and OSHA requirements for volatile materials
• Glass door and solid door options, including left-hinged configurations, so you can choose between quick visual inventory checks and maximum insulation
• Undercounter and built-in models for benches and space-constrained labs

Most units come standard with keyed door locks, audible/visual temperature alarms, probe access, and microprocessor-controlled temperature monitoring—the baseline features you need for consistent sample integrity and audit-ready documentation.

Laboratory Freezers

Our freezer lineup ranges from standard manual-defrost units up to ultra-low temperature (ULT) freezers, giving you options across every storage need:

• Manual defrost freezers — often the more energy-efficient choice for labs that can manage periodic defrost cycles
• Auto defrost freezers — less hands-on maintenance and reduced ice buildup for busier labs
• Ultra-low temperature (ULT) freezers — reaching down to -86°C for long-term storage of DNA, RNA, plasma, and other sensitive biological samples
• Refrigerator/freezer combination units, including -30°C and -40°C operation, for labs that need both zones in one footprint
• Flammable and pharmacy/vaccine freezers for specialty storage requirements
• Chest and upright configurations, including stainless steel undercounter models

As with our refrigerators, expect temperature alarms, keyed locks, and precise microprocessor control as standard—critical when you’re protecting high-value or irreplaceable samples.

Need Room-Temperature Storage Too?

Not every sample belongs in the cold. For products that require controlled ambient conditions instead of refrigeration, take a look at our controlled room temperature cabinets—a simple way to keep temperature-sensitive materials within spec without over-cooling them.

Choosing the Right Unit

Before you buy, think through:

• What you’re storing — vaccines, reagents, flammables, and biological samples each have different regulatory and safety requirements
• Temperature range — standard refrigeration, -30°C/-40°C freezing, or true ultra-low (-86°C) storage
• Maintenance tolerance — manual defrost saves energy; auto defrost saves labor
• Footprint — undercounter and built-in units for tight spaces vs. full-size uprights and chests for volume
