Hot plates are laboratory tools used to uniformly heat samples. Hot plates provide less heat, but do so without the danger associated with the open flame and higher temperatures of a Bunsen burner. Hot plates often include digital displays of temperature, hot surface warning indictators and magentic stirrers.

What is hot plate and its uses?
A hot plate is a portable self-contained tabletop small appliance cooktop that features one or more electric heating elements or gas burners. A hot plate can be used as a stand-alone appliance, but is often used as a substitute for one of the burners from an oven range or a kitchen stove.
What type of energy is a hot plate?
A hot plate changes electrical energy to thermal energy.
What is an electric hot plate used for in science?
Hot plates are an essential lab instrument used for heating lab materials and samples. There are several types available in the market, such as those with and without stirring systems. The hot plate system with a stirrer provides more temperature uniformity while heating samples.
How do you use a hot plate in science?
Hot plates: To use, plug its power cord into an outlet, turn the dial or use buttons to select the temperature you wish your experiment to reach, and the platform heats up. Hot plates produce heat via joule heating, or running an electrical current through a medium with high electrical resistance.
What is hot plate made of?
Hot plates are available with a number of different heating top styles. The most common types include those constructed from aluminum, ceramic materials or enamel.
What are the advantages of hot plate?
The hot plate welding process provides the following advantages: Ability to weld large parts and complex shapes and compound contours with little regard to part and joint geometry. Can weld tall, thin, non-supported interior walls. Highest joint strength of any weld process when welding PP,PE, TPE and EPDM materials.
Who invented the hot plate science?
Want to save up to 30% on your monthly bills? This tool helps you do just that. Scientists use hot plates in replacement of a live flame heat source, such as a Bunsen burner. In 1942, a New Jersey man named Arthur Rosinger filed a patent for a magnetic stirrer for use with a hot plate.
How do you use a hot plate safety?
Do not place thick-walled glassware, plastic containers, soft-glass bottles or jars on a hot plate. Ensure that the hotplate’s electrical cords and, if using, the temperature sensor probe wires, do not come in contact with the hot plate surface. TURN OFF the hot plate when not in use.
How do magnetic hot plates work?
Magnetic stirring hotplates contain an electromagnet, installed underneath the plate surface, which produces a rotating magnetic field across the plate. The magnetic field causes a stirring bar, immersed within the sample, to spin at a predefined speed (up to 2,500 rpm).
How does a hot plate get hot?
Function. A hot plate produces heat by using electricity, instead of traditional means of producing heat by using fire. How it does this is by running electricity through its heat coils. The heat coils have a relatively high level of electrical resistance.
How much energy do hot plates use?
Hot Plate Power Usage An average hot plate will draw approximately 1,200 watts of power. If the hot plate will be used for one hour each day over a 30-day period, it will consume 36 kilowatt-hours.
Why would you use a hot plate over a Bunsen burner?
Because there is no open flame, only a heated plate, they are regarded considerably safer than traditional Bunsen burners. In the laboratory, hot plates are widely used to initiate chemical reactions, heat samples, and perform a variety of other tasks.
Is hot plate same as induction?
Definition. A hot plate is a small portable electric device with a metal plate that is used in cooking, while an induction cooker is an electric device that cooks food by electrical induction.
What does a hot plate look like?
Hot plates look like a single electric stove burner, and that’s usually exactly what they are. People often use them if they have an efficiency apartment, dorm room, or a room in a boarding house. They are good for small cooking chores, such as boiling water or heating soup.
How long does a hot plate take to heat up?
Heat your plates in oven Stack plates in the oven from 140°F to 190°F (60°C to 90°C) for about 15 minutes. Be careful: avoid heating plates up to 175°F (80°C) as you can burn yourself by touching plates which are too hot. Some ovens have a warmer drawer, specifically designed to keep dishes hot before serving.
How do you set up a hot plate?
- Set the Device Up. First and foremost, you need to place the heat-resistant pan on top of the device.
- Turn the Device on. Once the device is set up, you would need to turn it on.
- Add the Ingredients.
- Remove the pan once you are finished!
Can you heat flammable liquids with a hot plate?
Never heat hazardous items (including flammable, corrosive, and toxic materials) on hot plates outside of a chemical fume hood. Never vigorously boil volatile solvents, such as ether, in open containers on a hot plate.
How many types of hot plates are there?
Types of Hot Plates Hot plates are separated into three categories based on the type of heating: electric, induction, and gas. Each type has a specific set of benefits. Understanding the features of the different types of heating elements can help you decide which is the best hot plate for your needs.
How hot is hot plate?
Temperature range is between 220° to 932° Fahrenheit.
How accurate are hot plates?
The hotplate is designed for 1% temperature accuracy over their entire range and will maintain a set temperature to +/- 1 C.
Is hotplate faster than gas?
Although electric stoves sometimes heat up more quickly than gas, cooks can control the level of heat more quickly and easily with a gas stove by turning the flame up or down.
What is hotplate or pass?
HOTPLATE- The hotplate or pass is the meeting point between the service staff and the food preparation staff. Active co operation and a good relationship between the members of staff of these two areas help to ensure that the customer receives an efficient and quick service of their meal.
Can I use hot plate with generator?
Hot Plates At less than half what toaster ovens and microwaves use, they work well with both standby and portable generators for cooking food during power outages. They are safe when used carefully and can be used to boil a pot of water or simmer dinner in a frying pan.
