Rotor Cavity Sleeves for GCM-12 & GCM-24 Series Micro Centrifuges — 0.2mL & 0.5mL Adapters, Sold Per Pack
These Globe Scientific Rotor Cavity Sleeves convert the standard rotor cavities of GCM-12 and GCM-24 series micro centrifuges to accept smaller 0.2mL or 0.5mL microcentrifuge and PCR tubes. Ideal for spinning down PCR reactions, pelleting small-volume nucleic acid preps, and consolidating quick-spin protocols on a single instrument without buying a dedicated rotor.

Frequently Asked Questions
Which centrifuges do these sleeves fit?
Each SKU is matched to a specific instrument family: the GCM-12-AD sleeves fit GCM-12 series rotors, and the GCM-24-AD sleeves fit GCM-24 series rotors. Select the option that matches your micro centrifuge model.
What is the difference between the 0.2mL and 0.5mL options?
The 0.2mL adapters size the rotor cavity down for thin-wall PCR and 0.2mL tubes, while the 0.5mL adapters accept standard 0.5mL microcentrifuge tubes. Choose by the tube format you run most often.
How many sleeves come in a pack?
Each listed SKU is supplied as a set sized to convert the rotor positions for that instrument family, sold as one pack at the per-pack price shown above.
Are the sleeves chemically resistant to solvents?
They handle aqueous buffers, dilute acids and bases, and alcohols well. Aromatic and chlorinated solvents are not recommended, and acetonitrile contact should be brief with prompt cleanup.
