Hotplate Stirrers
Benchmark Digital Hotplate Stirrers
- Large, easy-to-read backlit LCD display
- Durable, chemical-resistant 6.5 x 6.5 in. ceramic work surface
- Safety LED indicates when surface temperature exceeds 50°C
- Optional probe for precise sample temperature control
Benchmark Digital Hotplate Stirrers combine durability, precision, and safety in a compact, space-efficient design. Featuring a white ceramic work surface resistant to chemicals and thermal shock, these hotplates are perfect for use on crowded benchtops and inside biological hoods.
Advanced microprocessor controls allow for rapid and accurate adjustment of both stirring speed and plate temperature. The bright, backlit LCD continuously displays operating parameters, while a built-in safety LED alerts users when the surface is hot. When the optional temperature probe is connected, real-time feedback ensures precise temperature regulation within ±0.5°C directly in the sample.
With a 6.5-inch square plate, these hotplate stirrers accommodate a wide range of laboratory glassware including beakers, flasks, and bottles. Optional accessories such as the H3760-ROD support rod allow for secure mounting of thermometers and temperature probes during experiments.
Benchmark Analog Hotplate Stirrer
- 7.1 x 7.1 in. white ceramic work surface
- Variable stir speeds from 60 to 1500 rpm
- Precise temperature control up to 380°C
The Benchmark Analog Hotplate Stirrer offers reliable performance with straightforward control. Its smooth ceramic surface ensures excellent heat distribution and resistance to corrosion, while the compact 8 x 9 in. footprint makes it ideal for benchtops and fume hoods.
Intuitive turn-knob controls allow quick adjustment of both heating and stirring speeds, while safety indicator LEDs provide visual confirmation when either function is active. Compatible with common laboratory glassware sizes, this model includes an integrated support rod for thermometer or probe placement.
Both digital and analog Benchmark Hotplate Stirrers are built for dependable everyday performance and are well-suited for general laboratory mixing, heating, and solution preparation tasks.
Frequently Asked Questions
What is the difference between the digital and analog hotplate stirrers?
The digital models feature microprocessor controls and LCD displays for precise temperature and speed settings, while the analog models use manual knobs and indicator LEDs for simple, reliable operation.
Can the hotplate stirrers be used inside a biosafety cabinet?
Yes. Their compact, low-profile design and chemical-resistant ceramic surfaces make them suitable for use inside biosafety cabinets or fume hoods.
Does the optional temperature probe improve accuracy?
Absolutely. The optional probe provides real-time temperature feedback directly from the sample, ensuring accuracy within ±0.5°C during heating.
