Product Description
Carboys and oversized vessels need a broad plate and a magnetic drive strong enough to couple through large volumes. OHAUS Large Volume Stirrers cover capacities from 25 L to 200 L, with enough power to mix highly viscous materials.
This listing is for OHAUS item number 30573809: High Volume Magnetic Stirrer STHVAL, Analog, 25 L Capacity, 60-1,400 rpm, 120V. High Volume models use a cast aluminum housing and glass filled nylon top plate, while Large Capacity models are stainless steel throughout; each includes a 70 mm egg-shaped or 102 mm stir bar with pivot ring. Speed ramping eases the motor up for better coupling, and microprocessor control regulates speed precisely. Digital models add LED speed and time displays with a timer that shuts off stirring and sounds an alarm at zero, while the analog model uses a 1-10 dial knob. Add it to your LIGHT LABS order and keep your lab running with genuine OHAUS equipment.
