Pick the Right Laboratory Hot Plate!
The hot plate, either analog hot plates or digital hot plates, are crucial, portable, table-top devices for specific lab processes that call for heating samples. Hot plates feature an internal heating system and a flat surface. A variety of low-boiling solvents, including diethyl ether, pentane, hexane, acetone, and low-boiling petroleum ether, can be ignited by the device at temperatures up to 350 °C. Therefore, it is never advisable to heat these chemicals on a hot plate, especially in an open vessel.
A magnetic stirrer is included with some hot plates, which makes it simpler for the heated liquid to whirl continually and create a homogeneous mixture. In student laboratories, hot plates are preferred to hot tubs since the latter can overheat, spill, or catch fire. Additionally, it requires pricey mantles, takes longer to cool, and isn't compatible with all flask sizes.
Different Types of Hot Plates
Based on the design, hot plates are divided into three types:
Stirring Hot Plate
Standard Hot Plate
Magnetic Stirrer with Hot Plates
Based on the material, hot plates are of the following types:
Polypropylene Hot Plates
Ceramic Hot Plates
Stainless Steel Hot Plates
Aluminum Hot Plates
Things to Consider When Purchasing Lab Hot Plates
Size of the Hot Plate
Hot plates come in multiple shapes and sizes. Although there are several effective mini-hotplate stirrers available for purchase, it is advised to choose a plate larger than the vessel's size you will be working with. A larger plate, however, consumes a lot of electricity and needs a three-phase power source. As a result, consider your lab's amenities while making the instrument purchase.
Capacity
When buying a hot plate, the sample subject's heating capacity is crucial. The device's marketable capacity ranges from 20 liters to 200 liters
Temperature Control
Hot plates have two different ways to regulate the temperature:
When temperature accuracy is not crucial, choose a hot plate with an analog thermostat.
With a digital temperature control system, you can regulate the temperature precisely and choose from various settings for the heating rate and timer.
Required Temperature
The range of temperatures for the various hot plates on the market is between 250 and 550 °C. But it's always advised to pick an instrument whose temperature range exceeds that needed to heat the sample.
Sample Viscosity
Buy hot plates with strong drive magnets if you're working with viscous samples. Keep in mind that a larger hot plate cannot accommodate a sample with a high viscosity. A magnetically connected device lessens the possibility of the stir bar spinning out.
Safety Features
Safety is the top priority when using tools like hot plates such as analog hot plates. The device offers numerous safety features, including:
Current limit protection
Speed ramping
High-temperature setting
Safety shield
Hot top warning indicator
Probe protection
Temperature Uniformity
Buy a digital hot plate with a stirrer if you want your temperatures to be consistent. They do a fantastic job of heat distribution. A temperature meter and a surface tracker can be used to check the temperature uniformity.
Conclusion
A crucial piece of laboratory equipment, hot plates are used to heat samples and lab materials. The market offers a variety of models, including those with and without stirring systems.
