ChillBlock™ thermo-conductive metal alloy tube racks eliminate inconsistencies that result from inserting tubes directly into ice, dry ice, alcohol baths, water baths, and other common laboratory temperature sources

ChillBlock™ tube racks are available in a variety of sizes for vessels such as microcentrifuge tubes, cryogenic vials, PCR tubes, SBS-compliant strips and plates, and 15mL and 50mL tubes.

Racks adapt from ambient to <4°C in 60 to 90 seconds on ice; from ambient to –78°C in 5 to 7 minutes on dry ice; and from ambient to –140°C in 15 minutes when used above liquid nitrogen. Use Chillblock™ tube racks with heat sources such as a waterbath, incubator, hot plate, or oven.

ChillBlock™ racks have an anodized surface that is resistant to rust, corrosion, and abrasion. Alphanumeric well identification facilitates tube location. Racks can be autoclaved or cleaned with disinfectant.

Place the ChillBlock™ tube rack directly onto a temperature source and it will rapidly adapt to that temperature, from –150°C to over 100°C. ChillBlock™ tube racks ensure ±0.1°C temperature uniformity of all tubes when cooling, freezing, or heating. Samples and labels stay dry, organized, and upright at all times.
