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 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 (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.
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.
Dependable OHAUS Guardian 2000™ Hotplates and Stirrers are ideal for education and other lab environments that require affordable, everyday fast heating and reliable stirring up to 15 L. All three sizes offer simple knob control to easily adjust the heating and stirring functions. The durable housing includes a built-in support rod holder that accepts the optional support rod. Stirring models include PTFE-coated stir bars.
Generation Guardian 5000™ Hotplate Stirrers are engineered for safety and versatility across research, academic, and industrial settings. They offer powerful heating and mixing, with premium hardware and software to support diverse users safely and reliably. Heating models reach up to 550 °C and feature 3 temperature control modes for quick heating or precise heating without overshoot. Select from 5 models with 3 plate sizes.

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.

Stuart HotplateA heated glass ceramic plate mounted in a block of pure PTFE creates a powerful hotplate which is almost impervious to chemical attack, even by concentrated acids. When boiling acid solutions the CP300 is unaffected by the fumes and splashes which eventually destroy conventional hotplates. The chemical inertness of the PTFE body and ceramic top plate also means that much more aggressive cleaning agents can be used. For example, if all traces of metal must be removed, this hotplate can be washed with concentrated nitric acid! The separate temperature controller is connected to the hotplate via a 2 metre PTFE coated lead. This allows the hotplate to be located in a fume cupboard and the controller kept outside, well away from the corrosive environment. The controller is also fitted with a "Hot" warning light that will flash whenever the plate temperature of the hotplate is above 50° C and it will continue to operate when the hotplate is turned off and connected to the electricity supply. The hotplate has a large 200 mm square heated area so is ideal for heating either one large vessel or several smaller ones.

Stuart Analog Hotplate Stylish and economical general purpose hotplate stirrers designed with safety as well as performance in mind. The compact shape takes up less bench space and makes storage easier. The hotplate has an innovative LED temperature indicator scale and can also be used in conjunction with the SCT1 digital contact thermometer to accurately control sample temperature. The "Hot" warning light will flash whenever the plate temperature is above 50° C even when the hotplate is turned off and unplugged from the mains. Powerful magnets and motor give stirring speeds up to 2,000 rpm and is capable of mixing large volumes (up to 15 L). Model UC152 has a glass ceramic top which has excellent chemical resistance. The surface is easy to clean and the thermal properties allow very high plate temperatures while ensuring the edges stay cooler, reducing the chance of accidental burns. The white surface ensures good visibility of colour changes. The hotplate stirrers have an integral fitting for a retort rod and are supplied with 2 x 25 mm PTFE coated stir bars.
