Corning® CoolCell™ FTS30 (Sigma-Aldrich)
Login to see pricesBrand:
Sigma
Description
CoolCelll FTS30 utilizes a solid state core and controlled microconvection technology to evenly draw in -80°C freezer air through a bottom base vent, uniformly disperse the cold air around each vial in the central chamber and then release the thermal load from the vials through a top vent choke. The inner vial module holds 30 cryogenic vials and can be removed in one step. Each vial achieves a uniform and reproducible -1°C/minute freezing profile and thermal profiles are highly reproducible. Due to the low thermal mass of the uniform-density cross-linked polyethylene foam container, freezing can be conducted without a rise in local freezer temperature, thereby protecting nearby samples.
Application :
-For 30 standard 1.0 mL to 2.0 mL cryogenic vials.
-Controlled micro-convection for uniform freezing of 30 vials.
-Removable vial tray for one-step transfer of samples into and out of freezing chamber.
