Ohaus Multi-Position Stirrer
Ohaus Multi-Position Stirrers give synchronized, uniform mixing of several samples at once. The 318 × 279 mm top plate holds up to 9 × 250 mL or 4 × 1 L flasks. Its reflective white, glass-filled nylon surface is chemical resistant and minimizes unintended heating of samples. Speed ramping improves coupling and spin bar control and avoids splashing, while microprocessor control regulates speed precisely across the range.
