Compact, quiet, and efficient; ideal for personalized lab applications.
Designed for personal use, the PV-1 Vortex Mixer by Grant Instruments is a compact and low-profile device that fits almost anywhere in your lab space. Despite its small size, it offers uncompromised performance, featuring a reliable motor that ensures regulated and reproducible agitation across a variable speed range of 750 to 3000 rpm. This makes it suitable for both gentle and vigorous mixing, as well as pellet resuspension in tubes ranging from 0.5mL to 15mL, while accommodating tubes up to 20mm in diameter. Its operation is flexible with both 'continuous' and 'touch' modes, easily adjustable through a simple knob. Its quiet motor and sturdy design, complete with rubber suction pads for stability and vibration absorption, make the PV-1 incredibly user-friendly and effective for personal laboratory applications.
