HOTPLATE AND STIRRERS
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 popular sizes of borosilicate glass beakers, flasks, bottles and other vessels. The hotplate/magnetic stirrer model (H4000-HS) comes complete with a support rod for mounting thermometers and temperature probes.

BENCHMARK™ 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 obstruction, while a splash cover protects the connection mechanism from potential corrosion. Unlike most mixers, the Benchmark series is also supplied with a support stand and mounting hardware. The stirrer easily and securely attaches to the stand for compatibility with a variety of vessels, up to 24 inches high.
