Overview
Labotemp Refrigerated Benchtop Centrifuge LRC-204 is a refrigerated benchtop centrifuge offering high-speed operation and large capacity for clinical, research and high-throughput laboratory applications. It reaches up to 21,000 rpm (max RCF 31,554 × g) with precise temperature control from -20°C to 40°C (±1°C). The unit accepts both swing-out and angle rotors and provides microprocessor control, programmable memory and multiple safety and monitoring functions for reproducible results.
