Cleaning Your Taylor-Wharton CryoStorage System
The cryogenic vessel of all LABS CryoStorage Systems may need to be cleaned, and sterilized if the type of
stored product is changed or the unit is taken out of service. The vessel must be defrosted, cleaned, and
sterilized regardless of the type of stored product, prior to return to Taylor-Wharton for repair or maintenance.
Prior to cleaning, the unit must be warmed and defrosted following the defrosting procedure described above.
To clean and sterilize your defrosted LABS CryoStorage System, Spray the entire inner vessel surface with
ample amounts of an approved disinfectant. Allow surface contact to be maintained for a minimum of five
minutes. Rinse the inner vessel with water, remove all water and debris through the access opening located in
the carousels bottom tray, and vacuum or towel dry the surface. Spray the inner vessel surface with a 70%
alcohol to water solution and maintain surface contact for fifteen minutes. Rinse the inner vessel surface with
water and vacuum or towel dry excess water. Final dry the inner container, sensor line, and fill line using a
nitrogen gas purge.
