SCAT-81-1/1.8 Tubes

SCAT-81 Tubes for Cryogenic Storage of Plasma

Designed for reliability from collection through long-term storage, SCAT-81-1/1.8 tubes provide a robust solution for laboratories requiring both anticoagulant precision and cryogenic performance in a single format. The cryovials are pre-filled with 7.68 mg of citric acid, monohydrate to yield a final concentration of ~ 36.5 mM in 1 mL of plasma. This provides consistent, yet reversible, calcium chelation to preserve coagulation factor integrity and ensure reliable downstream analytical performance.

Flexible batch sizes available. Tubes are made to order: please allow 2-4 weeks for delivery. To initiate a quote, please fill out this form and email it to us at INFO@GOPROLYTIX.COM.
