Walter NextSpin centrifuges have an advanced and reliable CPU control system for accurate control of rpm, RCF and time. The back-lit, LCD screen provides full control over the set run time and rotational speed. Speed can be set and viewed in either rpm or RCF and there is a separate short spin button for quick spins. The safety lid-lock prevents the centrifuge lid from opening until the rotor has stopped spinning, and the lid then automatically opens when the operation has ended, to save processing time. The air flow design reduces rotor temperature to ensure samples remain cool, while the space around the chamber exterior absorbs noise and reduces vibration. Available with 6, 12 or 24 position rotor that can accomodate 15mL conical tubes or 3mL/5mL/8mL vacuum tubes.
