This magnetic stirrer hot plate is a complete laboratory unit with a 7 inch (178 x 178mm) square plate, stirring up to 10L of water. The 178 series comes in six models: stir and heat, heat only or stir only, with ceramic, ceramic coated aluminium or ceramic coated stainless steel plates, an LED display and knob control.
Features and benefits:
- Six models in one series: stir and heat, heat only or stir only, so you pick the function the bench needs
- Stirs up to 10L (H2O) per position, with stir bars from 25 to 60mm
- Stirring speed range of 150-1600rpm, listed for the MSA-178, MSHS-178 and MSHC-178 models
- Plate setting range of 35-400°C on aluminium models and 35-300°C on the stainless steel model; the ceramic models are listed at 35-500°C in one place and 35-400°C in the product photos, so check the model data before ordering if you need above 400°C
- Solution heating range of 35.0 to 200.0°C with 0.1°C resolution, and plate setting resolution of 1°C
- Temperature stability of ±1°C, and ±0.5°C control with the optional PT1000 external sensor (600ml water in a 600ml beaker, 30mm bar, 600rpm, 50°C)
- Hot warning indication, plus Error 1 and Error 2 overheat warnings for plate and medium on heating models
- Compact 192 x 293 x 100mm body with LED display and rotary knobs
Applications:
- Mixing and heating solutions in school and teaching laboratories
- Preparing reagents and buffers on the lab bench
- Brewing, food and cosmetics test batches
- Workshop and quality control sample preparation
Note: Models are rated 110-130V or 200-240V at 50/60Hz. The plug type is not stated in the listing, so check the plug and use a suitable UK adapter or fit. The MSA-178 stirs only and does not heat. Protection class is IP21, so keep spills off the unit and allow the plate to cool before moving it.

A: A rotating magnet under the plate turns a stir bar inside the vessel, which mixes the liquid without a shaft or paddle. This unit takes stir bars of 25 to 60mm.. Q: Which model is the stirrer only and which is heat only? A: The MSA-178 stirs only and the MHA-178 and MHC-178 heat only. The MSHA-178, MSHS-178 and MSHC-178 do both.. Q: How do I use a hot plate with a magnetic stirrer? A: Put the stir bar in the vessel, stand it centrally on the plate, start the stirring at a low speed, then raise the speed and set the temperature. Allow the plate to cool before moving it.. Q: What is the hottest plate setting available? A: Aluminium models reach 400°C and the stainless steel model 300°C. For the ceramic models the figures differ between sources, 500°C in the listing text and 400°C in the product photos, so confirm the model data if you need above 400°C.. Q: Can it stir 10 litres? A: Yes, the maximum stirring quantity per position is 10L of water, with a single stirring position..
