Biocision has launched the modular Cryoprep system, designed to make primary cell, stem cell and cord blood preservation simple, efficient and highly reproducible.
The system is said to offer a complete solution for all cell-freezing procedures, from ice-free cooling to convenient portability of cell samples and a controlled rate of freezing without alcohol.
Cyroprep comprises three precision designed and manufactured products: the Coolbox, Coolrack CFT and Coolcell, all based on Biocision's thermo-adaptive alloy.
The Coolbox system fits all 30-well Coolracks cryotubes and comes with a 2C cartridge for ice-free cell sample cooling.
The cartridges consist of a gel pack with thermo-conductive alloy shell, which enables fast cooling and recharge in a standard -20C lab freezer.
The 30-well Coolrack CFT features a micro-grip taper, which holds any 12.5mm cryotubes securely for convenient one-handed opening and closing.
Coolrack's high thermo-conductivity is said to ensure rapid and reproducible equilibration of all wells to within 0.1C of the source temperature.
In addition to eliminating temperature variability and providing stable, compact organisation, Coolrack saves time and reduces user errors and accidents commonly associated with directly immersing tubes in dry ice, dry ice/alcohol slurries or liquid nitrogen.
Coolcell holds 12 screw-cap 2ml cyrotubes and features a solid thermal core for consistent, controlled -1C/min cell freezing in a -80C freezer, without any alcohol.
Requiring only minutes between freezing cycles and no maintenance, Coolcell is said to be ideal for multiple batch freezing, ensuring identical freezing for all samples.
The result is increased reproducibility and superior cell viability and function for scientific, clinical and diagnostic procedures.
Because of the low thermal mass design, Coolcells release only one-third of the heat given off by an alcohol-filled container.
This means multiple Coolcells may be frozen simultaneously in a -80C freezer without warming up the freezer or jeopardising previously frozen samples.
Tina Sepp, vice-president of new product development at Biocision, said: 'The Cryoprep system is an ideal workstation set for ice-free cold cryo vial preparation and alcohol-free cell freezing, enhancing both efficiency and reproducibility.
'Up to 30 cryo vial samples can be kept cold and dry using Coolrack and Coolbox, before freezing 12 samples per Coolcell in a -80C freezer or dry ice locker.
'Versatility is also a key benefit of this modular system.
'For example, compact design and ice-free cartridge technology make Coolrack and Coolbox an ideal choice for use in tissue culture hoods, but dry ice, wet ice or liquid nitrogen may also be used as cooling sources,' she added.
