Powerful Magnetic Stirrers available in either four or nine position capacities provide precise speed control that deliver repeatable performance. Offered in both digital and non-digital models.

For Dissolution Studies, Titrations, Media/Reagent Preparations, Synchronized Stirring of multiple samples. Independent LED displays for speed and time (on digital models); Knob with 1-10 dial markings (on non-digital models). Cast aluminum housing, glass filled nylon top plate. Includes stir bars to accommodate each stirring position. Speed ramping feature slowly increases motor speed for enhanced coupling & improved stirring. Microprocessor-controlled for precise speed regulation. Timer counts up or when programmed to a set time will turn off stirring & sound alarm when timer reaches zero.

Features:

The 318 x 279 mm top plate accommodates up to 9x250 mL or 4 x 1 L flasks. The glass-filled nylon surface has a reflective white color, is chemical-resistant minimizes unintended heating of samples.
Speed ramping feature slowly increases the motor speed for improved safety and enhanced coupling. Avoids splashing, improves spin bar control and provides excellent low-end speed control.
Digital models have touchpad controls for input of speed & time. Non-digital models have an adjustment knob with dial markings from 1-10. The microprocessor regulates adjustments throughout the range.
