CBS Hydrophobic plugged Embryo Straws

Description / Use
Storage and preservation of embryos.
The special design and the mode of filling and sealing of CBS High Security straws for cryopreservation of human biological samples makes them fully hermetic, in ultra low temperatures.
Manufactured from biocompa-tible materials, they are used in medically assisted procreation techniques and particularly for embryo preservation. The CBS embryo straw is a clear, flexible tube made of ionomeric resin.

L: 33 mm / Internal Ø: 2.25 mm.

Its disposable, transparent filling tip allows introduction of the embryo without contaminating the opening. Two distinct parts separated by a hydrophobic plug guarantee embryo sterility during introduction and recovery after thawing.
The first part holds the embryo and the adjacent dilution solvent (working volume 0.3 ml) while the second part allows insertion of a colored identification rod which also facilitates easy identification in liquid nitrogen.

Identification
The CBS embryo straw carries a tamper-proof color-coded indentification rod to guarantee sample traceability.

Filling and sealing
Straws are filled by aspiration using a micro-aspirator according to a specific protocol.
The impermeability of the seal is only guaranteed if the CBS straws are closed with the SYMS sealing system.
