Frosty Mate™ Color Change Freezer Rack – Polypropylene, 24-Place, Temperature-Sensitive Sample Organizer

{ "44267759927432": { "extra_description": "The Frosty Mate™ 24-Place Color Change Freezer Rack is a high-performance polypropylene rack designed for reliable sample storage, transport, and temperature monitoring. Featuring innovative color-change technology, the rack shifts from green to yellow when its temperature exceeds 7°C, giving you an instant visual cue. It can maintain a temperature below 4°C for up to 3.5 hours at room temperature with the lid on, making it ideal for protecting temperature-sensitive biological samples. The 6 x 4 grid holds 1.5 mL to 2 mL microtubes and includes an adapter for six 0.5 mL tubes. With an operating range from -86°C to +121°C and full autoclavability, it’s perfect for lab use, cold chain transport, and secure storage." }, "44267759960200": { "extra_description": "The Frosty Mate™ 96-Place Color Change Freezer Rack is an advanced polypropylene rack designed for PCR tubes and strips, offering reliable cold storage and instant temperature awareness.
