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.

• Anodised surface that is resistant to rust, corrosion, and abrasion
• Alphanumeric well identification facilitates tube location
• Racks can be autoclaved or cleaned with disinfectant

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 15 and 50 ml 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.

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, organised, and upright at all times.
