CoolRack XT CFT24

CoolRack XT CFT24 modules are precision-engineered sample modules manufactured from a novel thermo-conductive alloy material, designed to evenly distribute temperature across all wells providing uniform and consistent temperature to all samples (+/-0.1°C) *Ideal for cooling, snap freezing, heating or thawing *Helps keep samples organized and dry *All tubes upright and indexed *Reproducible method *SBS footprint "Gripping" wells for one-hand vial opening/closing.

  • CoolRack thermo-conductive tube modules eliminate variability which originates from tubes placed directly into ice, dry ice, alcohol baths, water baths and other temperature sources
  • CoolRack modules ensure +/- 0.1°C temperature uniformity across all tubes when cooling, snap freezing, heating or thawing
  • Suggested applications include cooling reagents such as restriction enzymes, dNTPs and antibodies, alcohol-free dry ice snap freezing of tissue, virus and bacteria samples and bench top cryogenic tube sorting in liquid nitrogen
  • All CoolRack modules may be autoclaved, high heat sterilized or decontaminated with bleach, alcohol or other disinfectants or lab detergents

Secure sample preparation

  • Removes all problems created by placing sample directly in ice: variable sample temperature, wet labels, contamination risk
  • All samples <4°C and uniform in temperature (+/- 0.1°C)
  • Samples organized, secure and dry
  • All tubes upright and indexed
  • "Gripping" wells for one-hand vial opening/closing

Versatility and performance

Regardless of temperatures source

  • Samples stand upright and organized
  • Reproducible method
  • SBS-footprint: ideal for benchtop cooling, then quick transfer to automated platforms for approx. 10-20 minutes of cold processing

On ice

  • Adapts from ambient (25˚C) to <4˚C in 60-90 seconds*
  • Samples and labels stay dry
  • Hours of ice cooling without direct ice contact

On dry ice

  • Adapts from ambient (25˚C) to -78˚C in approximately 5-7 minutes*
  • Eliminates ethanol from snap freezing
  • Equal or better freezing rate as compared to direct immersion into dry ice or alcohol slurry

In liquid nitrogen

  • Adapts from ambient (25˚C) to approximately -150˚C in approximately 12-14 minutes*
  • Vapor barrier protects from ambient air
  • No direct contact between samples and LN2

Heat sources

  • Use with water baths, hot plates, incubators and other heat sources to keep samples warm

*Average cooling rate from room temperature

How it works: ease of use

  • CoolRack on ice: heat from the relatively warmer CoolRack module is transferred to cooling source (wet or dry ice, cartridge, LN2) until equilibrium is reached
  • CoolRack in water bath: heat is transferred from water bath toward relatively cooler CoolRack until equilibrium is reached
