Details: The Frey Scientific 528339 Student Stirring Plate is has a one-piece aluminum top for stirring glassware and contents between 100 to 1200rpm, and includes a round 4.5-inch diameter top plate that is durable and crack- and chip-resistant, a control knob with 1 to 10 dial markings, a micro-switch under top plate that activates with a weight of approximately 50 grams (1.75oz.) and ceases when the mixing vessel is removed, and a built-in support rod holder with locking knob. Stirrers are used to stir glassware and contents in laboratories. This stirrer features a compact design to save bench space. A motor and magnet provides reliable and consistent stirring when activated by the weight sensitive micro-switch under the top plate. The built-in support rod holder with locking knob at rear holds a standard threaded support rod to suspend instrumentation such as clamps and probes. The unit operates in environments from 4 to 40 degrees C (39 to 104 degrees F). The stirrer comes with a 1.5" (3.8cm) polytetrafluoroethylene (PTFE) coated stir bar and a 72" (234cm) detachable, 3-wire cord and plug. Specifications Speed range 100 to 1200rpm Speed stability + or - 2 percent Maximum capacity 1000mL H2O Top plate composition Aluminum Power supply 120V 50/60 Hz Top plate dimensions 4.5 inch diameter Body dimensions 5.4 x 5.75 x 6.5 inches (H x W x D) Weight 4.5lb. H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back. Researchers, professionals and hobbyists use stirrers to stir a variety of liquids and solutions in chemistry, food and beverage, biology, lab, and home applications. Stirrers can have either a digital or an analog display, and can show stirring speed. Stirrer surfaces are commonly made of ceramic-glass or stainless steel, and have coatings such as porcelain. They come in a variety of dimensions. Some units can work with instruments such as thermometers that can be supported with clamps and rods.
