PR1MA™ Hotplates, Magnetic Stirrers, and Hotplate-Stirrers

• 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

PR1MA™ 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 inch 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 (MS-1500) comes complete with a support rod for mounting thermometers and temperature probes.

Benchmark Scientific Hotplates and Stirrers provide reliable performance and safe operation for everyday laboratory use.  With two sizes (7 inch or 10 inch) to choose from, each model features a durable, chemical resistant, white ceramic top plate and advanced microprocessor controls.  The constant monitoring system provides precise control of temperature (heating models only) with rapid heating and faster boiling times.  In addition, the powerful motor drive system of the magnetic stirrer ensures efficient mixing in larger vessels and more viscous samples.
 
Temperature and/or mixing speed can be viewed at all times on the large digital display and safety LED illuminates when the top plate temperature exceeds 50°C.  An optional external temperature probe can be used for applications that require precise temperature control.  The probe provides direct feedback to the microprocessor with adjustments for maintaining the selected sample temperature within ±1°C.  An optional clamp assembly (H3770-CS) is available for mounting thermometers, temperature probes, etc.

HS-10 PLUS™ Multi-functional Hotplate Stirrer

• Multi-functional design
• Simultaneously heat and stir up to 5 vessels
• Large, 10 x 10 in., white, ceramic top plate
• Digital speed and temperature control
• Safety LED indicates hot surface
• Control actual sample temperature (with optional probe) 

The Benchmark HS-10 Plus™ Hotplate Stirrer supports heating and stirring of up to five sample vessels, simultaneously. Unlike traditional multi-position stirrers, the HS-10 model features a large (10 x 10 in.) square top plate that provides the flexibility to heat and stir larger sample vessels, up to ten inches in diameter (including 1 x 10 L bottles).

The top-plate features a durable, chemically resistant, white-ceramic coating that provides exceptionally uniform heating for temperature up to 400°C. The five stirring locations are clearly marked, to ease sample loading and ensuring proper positioning of vessels.

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.

AccuPlate™ digital hot plates and stirrers are powerful, versatile and easy to use. Every unit is built for consistent performance and long-term reliability. With three models to choose from, there is an AccuPlate™ hot plate and stirrer to meet your lab's needs.

Ceramic Durability and Resistance

Each AccuPlate™ is equipped with a Pyroceram® ceramic top plate that is extremely durable, easy to clean and is highly resistant to chemical attack. In addition, the ceramic plates can reach higher temperatures (rated to 550°C) than metal topped units and the white color makes it easy to view color changes in applications such as titrations. The AccuPlate™ Hotplate and Hotplate Stirrer models incorporate a powerful heating element positioned directly beneath the ceramic top plate. This provides optimal heat transfer to the plate and sample while minimizing heat transfer to the electronics and housing.

Acceleration Regulation

The Stirrer and Hotplate Stirrer utilize a powerful motor drive system paired with strong permanent magnets to ensure a consistent connection to the stir bar. The control software is designed to minimize stir bar decoupling by regulating the acceleration rate of the motor. The durable cast aluminum housing and angled faceplate protect the electronics in the event of an accidental spill. The Hotplate and Hotplate Stirrer models also feature a bright red "Hot Top" indicator to alert users that the ceramic top is too hot to touch - even if the heater is off, the light will remain on until the top has cooled to a safe temperature.
