The Crit Carrier (patent pending) is specifically designed to run hematocrits on your Horizontal Centrifuge (minimum 5,000 rpms). Simply insert your hematocrit capillary tubes into the carrier, place the carriers in opposing tube sleeves for a balanced load, and spin at 5,000 rpms for 8 minutes for a clear separation. The Crit Carrier converts the J0501sq centrifuge into a Hematocrit Centrifuge. Save counter space and the need to purchase an additional hematocrit centrifuge. Spins up to 8 standard 75mm capillary tubes.
Crit-Carriers only work with high-speed horizontal centrifuges, like the J-501sq and the original Straight 8-5k.
