Rotor Cavity Sleeves for GCM Series Mini Centrifuges — 0.2 mL & 0.5 mL Adapters, Pack of 6
The Globe Scientific Rotor Cavity Sleeves convert the standard rotor cavity of GCM Series mini centrifuges to accept smaller-format tubes, supporting quick-spin protocols, PCR setup, and sample concentration. Each sleeve drops directly into the rotor well, letting one instrument run both 0.2 mL and 1.5/2.0 mL workflows without a rotor swap.

Frequently Asked Questions
Which centrifuges accept these rotor cavity sleeves?
These sleeves are designed specifically for Globe Scientific GCM Series Mini Centrifuges. They drop into the existing rotor wells, so no rotor replacement is required.
What tube sizes does each sleeve support?
SKU GCM-AD2 adapts the cavity for 0.2 mL microcentrifuge tubes, while GCM-AD5 adapts it for 0.5 mL tubes. Choose the version matching your tube format.
How many sleeves come in a pack?
Each item is sold as a pack of 6 sleeves, sufficient to convert a full GCM rotor set. Both volume options are priced per pack at $38.60.
Are the sleeves autoclavable?
The sleeves are molded plastic and supplied non-sterile. Verify the temperature limits of your specific GCM accessory documentation before autoclaving, as repeated high-heat cycles may affect dimensional fit.
