Weighted ID Stick 30 mm

Internal colour-coding and ID of 0.3 ml CBS high-security sperm or embryo straws.

• 30 mm; designed to fit inside CBS 0.3 ml high-security straws.
• Each stick is weighted so filled straws won’t float when immersed in liquid nitrogen (prevents buoyancy from extra air bubbles).
• Fits the CBS two-compartment “high security” straw design so identification can be sealed inside (tamper-resistant).
