GCM Series Mini Centrifuge Rotors, 7000 rpm — 8-Place and 2 x 8 PCR Strip Formats (Sold Each)
These GCM Series Mini Centrifuge Rotors are interchangeable rotors engineered for Globe Scientific GCM Series mini centrifuges, supporting rapid spin-downs, microcentrifuge pelleting, and PCR strip collection at bench scale. Choose the 8-place rotor for standard 1.5/2.0 mL tubes or the 2 x 8 position rotor for 0.2 mL PCR tubes and strips. Tool-free swapping lets one instrument cover multiple sample formats.

Frequently Asked Questions
Which centrifuges accept these rotors?
Both rotors are designed for the Globe Scientific GCM Series mini centrifuges and are not intended for other instrument lines.
Can one centrifuge use both rotor formats?
Yes. The 8-place and 2 x 8 PCR rotors are interchangeable on a single GCM unit, letting you switch between tube and strip formats without tools.
What tube sizes does the 8-place rotor hold?
The GCM-ROT 8-place rotor accommodates standard 1.5 mL and 2.0 mL microcentrifuge tubes and spins at up to 7000 rpm.
Are these rotors sold individually?
Yes. Each SKU is sold as a single rotor (each), priced per unit as listed above.
