• Stir up to 150-liter volumes
• Chemically resistant white ceramic top surface
• Powerful motor ideal for large vessel applications
• Digital control of both stirring speed and timer

Benchmark HCS Series of high-capacity stirrers provide reliable performance and safe operation for high throughput lab use. These stirrers feature a durable, chemically resistant white ceramic top plate, which protects the internals of the stirrer from leaks and spills. The powerful motor drive system ensures efficient and thorough mixing in large vessels and viscous samples.

Ideal for large-scale stirring applications, the HCS Series offers 50-liter and 150-liter maximum capacity models, as HCS-50L and HCS-150L respectively. Mixing speed can be viewed on the large digital display, and speed is adjustable from 50 rpm to 1500 rpm (HCS-50L) or 1200 rpm (HCS-150L). The built-in timer settings range from 1 second to 9 hours and include a continuous operation setting.

BENCHMARK™ INDUSTRIAL MULTI-POSITION HOTPLATE STIRRERS

The stirring speed is continuously adjustable from 100 to 1500rpm. For temperature sensitive samples, the MiniMag is incubator and cold-room safe for use from +4°C to +45°C.

• “Mini” sized, less than 3.5″ wide
• Adjustable speed control, 100 to 1500rpm
• Effectively mixes volumes up to 1.5L

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.

• Ceramic work surface, 7.1 x 7.1 in.
• Stir speed from 60 to 1500 rpm
• Temperature control up to 380°C
• Three models: heat-stir, heat only or stir only

Temperature and mixing speed can be viewed  on the large digital display and a safety LED illuminates when the top plate temperature exceeds 50°C. An external temperature probe can also be used for applications that require precise control of sample temperature. The probe provides direct feedback to the microprocessor with constant monitoring and adjustments for maintaining the selected temperature in the sample within +/- 1°C. All models are compatible with borosilicate glass beakers and other vessels up to 20 liters (15 L maximum stirring volume). An optional clamp assembly (H3770-CS) is available for mounting thermometers, temperature probes, etc.

• Large, 10 x 10-inch white ceramic top plate
• Maximum stirring capacity 15 L
• Digital speed and temperature control
• Safety LED indicates hot surface
• Control actual sample temperature (with optional probe)

With a square 7 in. work surface, all models are compatible with a wide variety of popular sizes of borosilicate glass beakers, flasks, bottles and other vessels. An optional support rod (H3770-ROD) is available for mounting thermometers, temperature probes, etc.

• Large, ceramic work surface, 7 x 7 in
• Safety LED indicates hot surface
• 5L stir capacity
• Control actual sample temperature (with optional probe)
