Frequently asked questions
Can a round-bottom flask be placed directly on a hot plate?
It is not stable without suitable support and does not make uniform contact. A heating mantle or suitable bath is normally considered for round-bottom flasks.
Does a heating mantle need a controller?
Many applications require controlled power or temperature regulation. The correct arrangement depends on the mantle design and process.
Can a hot plate be used with flammable solvents?
Only after a proper risk assessment and with equipment and ventilation suitable for the hazard. Standard hot plates are not automatically suitable for every solvent application.
Where can I buy laboratory heating equipment?

Planning a hot plate with controller enquiry
The live catalogue describes a laboratory hot plate for controlled heating of samples, liquids and solutions. The controller type and sensing arrangement are not specified. A controller may regulate the plate or use another sensing point, so the requested process should be discussed before selecting the unit.
Match the configuration to the procedure
Specify the vessel sizes, sample workload, controller requirements and available bench space. Ask for the exact model specification before ordering.
Does this model include digital control or stirring?
Neither feature is established by the current product record. Ask Hasthas to confirm the controller, sensing point, plate dimensions, operating range and whether stirring is included. These should appear in the final quotation.
Plan care before installation
Follow the supplied instructions for vessel compatibility, placement and cleaning. Keep liquids away from the controls and wait for safe cooling before handling the plate.
Review the Hot Plate with Controller specifications and available configurations before preparing a purchase request. Keep the required performance separate from any optional items, and ask for each included accessory to be identified in the quotation.

A practical choice based on the vessel
Start by placing the vessel, rather than the heater, at the centre of the decision. A flat-bottomed vessel needs stable contact with a suitable heated surface. A round-bottomed flask needs the support and fit intended for its geometry. Adapting the wrong heater with an improvised support can introduce handling problems even when the equipment appears to provide enough heat.
Next decide what is being controlled. A power adjustment changes energy input; it is not automatically a measurement of liquid temperature. Where the procedure requires temperature feedback, ask how the selected configuration senses the relevant condition. Also establish whether mixing is required and how it will be provided. Neither the words hot plate nor heating mantle establish that a stirrer is included.
Compare the complete bench arrangement
- Vessel shape, size, stability and access for loading or sampling.
- The required sensing and control arrangement for the procedure.
- Whether a separate stirring system or support is needed.
- Compatibility with the material and the laboratory’s safety assessment.
- Cleaning, spill response and access for safe shutdown.
The live Hasthas catalogue also contains a hot plate with controller. Its numerical ratings and controller type are not specified, so request those details explicitly. Use one description of the intended procedure across the enquiries to compare the proposed solutions fairly.
