Product Description
Stir four or nine samples at the same speed and time, and side-by-side comparisons become far more reliable. OHAUS Multi-Position Stirrers deliver powerful magnetic stirring with precise speed control for synchronized work in digital and analog versions.
This listing is for OHAUS item number 30573794: Multi-Position Magnetic Stirrer STMP9AL, Analog, 9 Positions, 9 x 250 mL, 60-1,400 rpm. Each unit has a cast aluminum housing, a glass filled nylon top plate and a stir bar for every position. Speed runs from 60 to 1,400 rpm, with ramping that eases the motor up for better coupling and microprocessor regulation for steady speed. Digital models add LED speed and time displays, and the timer can count up or stop stirring and sound an alarm at zero; all are UL and cUL certified for 120 V. Order it from LIGHT LABS alongside the rest of your OHAUS balances, weights and lab equipment.
