Benchmark Scientific Included Propeller, Stainless Steel 4 Arm for Overhead Stirrers

Benchmark's Overhead Stirrers feature high torque and advanced digital microprocessor control for smooth mixing of low and medium viscosity samples. Speed and run time are accurately set and monitored on the LCD screen. Both the 20L and 40L capacity models are supplied with a 4 arm stainless steel propeller. Additional steel and Teflon accessories are available. A feed-through chuck holds accessory shafts firmly in place and is easily tightened and loosened without tools. The overhead stirrers are protected from damage by sensors that shut down operation in the case of high viscosity or ...

The Benchmark Multi-Position Stirring Hotplates provide simultaneous heating and stirring of multiple samples. The large top-plates feature a durable, chemically resistant, white, ceramic coating that provides exceptionally uniform temperature control up to 120°C. Both mixing speed and temperature are conveniently controlled on the digital display, which also features a safety LED that warns the user when the top plate is hot and unsafe to touch. Two models are available, offering either 5 or 10 position capacity. Each stirring position is driven by an independent motor, providing ...

Benchmark Scientific Hotplates, Stirrers and Hotplate Stirrers provide reliable performance and safe operation for everyday laboratory use. Our space efficient 7x7 inch and 10x10 inch hotplate/stirrer series features a durable, chemical resistant white ceramic top plate and advanced microprocessor controls. The constant monitoring system provides precise control of temperature with rapid heating and faster boiling times. In addition, the powerful motor drive system ensures efficient mixing in larger and more viscous samples.Temperature (Ambient +5° to 400°C) and mixing speed ...

Benchmark hotplates, stirrers and hotplate-stirrers feature an exceptionally durable, chemical resistant white ceramic work surface. Their space-efficient design (8 X 9 in. footprint), makes them ideal for use on crowded benchtops and inside of bio-hoods. Advanced microprocessor controls with convenient turn knobs allow quick, precise adjustment and maintenance of speed and temperature. Safety indicator LED's on the front panel indicate when the heating and/or stirring functions have been activated. With a square 7.1 in work surface, all three models are compatible with a wide variety of ...

Standard stirring shaft. It generates an axial flow in the container with suction of the substance from the bottom towards the top and localized occurrence of shearing forces.
