Cryogenic Straw Labels

In vitro Labs, cryo labels for straws

Many tissue banks and cell banks specialize in in-vitro fertilization (IVF) procedures using frozen oocytes, sperm and embryos. The frozen samples are placed in dedicated cryogenic straws which subsequently get stored inside liquid nitrogen tanks at -196ºC for long-term secure storage. They can be used in research and clinical labs, clinics, as well as farms and zoos, for both human and animal samples.

GA International has been providing cryogenic straw labels for IVF medical laboratories and veterinary stations for over a decade. Our StrawTAG™ cryogenic labels have been approved for 0.25 ml and 0.5 ml straws of different configurations, following extensive testing in liquid nitrogen. These precisely designed cryo straw labels can withstand short and long-term cryo-preservation inside liquid nitrogen Dewars (liquid and vapour phase), freezers (-20ºC, -80ºC, -120ºC) and transport on dry ice. The cryo IVF straw labels can withstand the vitrification process, the ultra-rapid freezing of oocytes and embryos used to avoid the formation of ice crystals. StrawTAG™ labels are compatible with all standard cryo straws as well as high security straws including the CBS High Security vitrification straws.

The labels are provided in standard white, as well as an assortment of colours for quick and easy identification using colour-coding practices. The labels can be printed with all major thermal transfer printers (CAB, Citizen, Datamax O’neil, Zebra, etc.) or can be written on manually using our cryo markers, with a transparent laminate applied over the printed area, safeguarding the information underneath from scratches and any chemical exposure. The adhesive and the facestock material easily conform to the small diameter of the straws with the label adhering strongly and permanently.

Compliances and Certification: Our IVF cryogenic straw labels are compliant with FDA–21CFR175.105 for non-direct food contact. These labels have been tested for and demonstrated to have very low levels of Volatile Organic Compounds (VOC) which allow them to be used in IVF clinics worldwide (subject to end user evaluation).The labels are resistant to standard gas sterilization, consisting of a 60-minute exposure to 759mg/L of ethylene oxide gas, at 55oC, and 40-80% relative humidity, followed by a two-hour aeration cycle.Cryo StrawTags™ can also be sterilized by Gamma irradiation (25-50 KGy).

Printing Kits: We provide ready to use cryo straw label printing kits that come with a high-resolution thermal transfer printer, a roll of cryogenic straw labels of your choice, a resin ribbon and state of the art barcoding software with database connection wizard. The software has the capacity to connect to Database and Excel sheets and can print serialized numbers, barcodes, alphanumeric information and text using true type fonts, stamp-date with a wide range of advanced features and programming. Certain models of cryogenic straw kits also include a barcode scanner.
