Microcentrifuges
Microcentrifuges are indispensable for labs needing quick and efficient sample separations in small volumes. Be Scientific offers a refined selection of Sigma microcentrifuges designed for speed, safety, and adaptability.
The Sigma 1-14: This model combines compact design with powerful specifications - spinning up to 14,800 rpm to generate about 16,160 × g, with a 24-tube capacity. It includes large buttons, a clear display, a motorised lid lock, overspeed monitoring, and rapid acceleration and braking, all while remaining quiet in operation. Spurs of noise are under 54 dB.
Sigma 1-14K, Refrigerated Counterpart: This Sigma 1-14K, adds precise cooling from - 10 °C to +40 °C, ten programmable memory slots, pre-cooling, and standing-cool functionality, ensuring samples stay cold even at maximum spin. Noise is reduced to under 49 dB.
Sigma 1-16K: Stepping up in performance, the Sigma 1-16K offers stronger centrifugation - exceeding 20,600 × g at 15,000 rpm. It features a stainless steel bowl, motorised lid lock, short acceleration/braking, adjustable fan for quiet cooling, and rotor options up to 36 × 2 ml.
Across all models, features like easy rotor compatibility, quiet motors, programmable control, and secure operation make these microcentrifuges ideal for DNA/RNA prep, cell pelleting, clinical analysis, and teaching labs. Based in Shropshire, our team provides expert support to help you match the right microcentrifuge to your needs.
FAQs
How fast do these microcentrifuges spin and what centrifugation force do they generate?
The Sigma 1-14 achieves up to 14,800 rpm (~16,160 × g). The Sigma 1-16K reaches 15,000 rpm, generating over 20,600 × g.
Are refrigerated models available for temperature-sensitive samples?
Yes. The Sigma 1-14K offers cooling from - 10 °C to +40 °C with pre-cool and standing-cool functions. The Sigma 1-16K also maintains +4 °C during high-speed runs.
How quiet are these units during operation?
The Sigma 1-14 runs at under 54 dB, while the Sigma 1-14K is quieter at under 49 dB, thanks to better cooling and fan control.
Are they programmable and secure?
Yes. All include motorised lid locks; the Sigma 1-14K has ten programmable slots. The Sigma 1-16K also features user programs and quick locking for safe, consistent usage.
