Labels for refrigeration, freezing and cryo storage

For labelling during cold storage and transportation of laboratory samples.

Typical Uses

The Flex-A-Freeze range has been developed to label laboratory plastic and glassware at room temperature and then withstand cold and freezer storage conditions including transportation on dry ice at -80°c and cryo storage down to -196°c. 

The labels are typically printed with important sample information such as tissue type, blood, plasma, urine, semen etc., date, location, lot number, patient name, date of birth and initials of the healthcare professional.

The data can be printed by a thermal transfer printer in a manual readable format or in a digital format such as linear, 2D barcodes and QR codes for fast identification and automated sample retrieval.

They are ideally suited for the labelling of vials, test tubes, polypropylene well plates, cryo storage boxes and other similar freezer storage plasticware. 

Durability

Flex-A-Freeze labels will also resist steam sterilisation handling and occasional splashes of detergent, isopropyl and other alcohols when printed with Flex-A-Porte Ultra Ribbons... learn more. 

Adhesive

The adhesive is a special permanent acrylic adhesive designed to withstand cryogenic temperatures down to -196°c when applied at a minimum application temperature of 10°c.

Labels should be stuck onto the surface for 24 hours in ambient temperature conditions to provide the best adhesive performance in prolonged cryogenic storage.

Preliminary tests have to be conducted on the actual surface in real conditions in order to satisfy suitability for the purpose. Contact us for samples
