Hot Plates – The Essential Laboratory Equipment

What are hotplates?What are hotplates?

A hotplate is a highly portable device that can have up to two gas burners. There are two sizes of hotplates available though. One is the single burner and the bigger one and the other is the double burner one. There are two types of burners available too and it can also be a heating element (electric too) for some. The portable one is small enough to be used on the table top as a standalone device. The main feature of hot plate is that it does not require any other resource except electricity to operate.

What is a hot plate used for in the lab?The hot plate is a vital device that is used in a laboratory to heat samples

The hot plate is a vital device that is used in a laboratory to heat samples. The fact that it has the ability to heat the sample without any exposed flames is one of the major advantages. It is a device that can be used on a daily basis for temperatures as high as 100 degrees and even higher.

It is important to check material of the hot plate surface. There is a big advantage of using a flat plate however the hot plate can be made from several materials like ceramic, aluminium or enamel. An aluminium heating plate can distribute the heat evenly and that too quite fast and efficiently. It is a device that is easy to clean and maintain as well. Although care must be taken against corrosion.

The other materials used to make a hot plate are ceramic and enamel. These too have their own unique characteristics. They are both considered to be more durable in terms to handling temperature as well as strong chemicals. These plate can resist higher temperature and are also sensitive to color change. Hence the color change due while heating of plate is more noticeable.

What is a Hotplate Magnetic Stirrer and how it’s Works?

Information about what a Hotplate Magnetic Stirrer is and how it’s work:

A Hotplate Magnetic Stirrer which is more of like an electric burner is mostly used for cooking purposes in kitchen or other places like hostels, motels etc. but the same is also very much appropriate for scientific tryouts in laboratories like multi position hotplate stirrer. Hotplate Magnetic Stirrer

Hotplate mechanics:

The mechanism used is quite simple to explain in traditional electric hotplates. When the device is connected to a socket via electric plug, the coils fitted within the plate gets heated and serves the purpose. Now days instead of the traditional heating methods, halogen heating is the new technique used which heats way quicker than the old ones. Moreover induction hotplates are also in very much demand because of the greater safety they provide during processes.

Formation of hotplates:

The main portion of the electric hotplate i.e. the plate is made of heavy metals like cast iron or ceramic. Remainder body part is made of either steel or plastic. The no. of burners depends on the type of hotplate but mostly they have one or two burners along with multiple knobs for various settings like temperature or heat warning.

Hotplate’s specialties:

  • Quite inexpensive in nature as compared to other devices
  • Portable
  • Easy to use
  • Occupies smaller space

Type of hotplates:

Generally there are two common types of hotplates:

1) Electric Hotplate: uses Aluminum/ceramic/Enamel/iron surface or coils which gets heated when electricity flows. There are pros and cons attached to all types of surfaces. These hotplates are although cheap in cost but risky and surface remains hot for quite a long time

2) Induction Hotplate: This uses the magnetic induction heating technique by creating a magnetic field to heat the vessel. They are costly but quite safe and time taken to cool down the surface is also quite less.

Uses at Laboratories for Scientific Researches:Uses at Laboratories for Scientific Researches

Generally hotplates are used at laboratories to heat glassware & its contents, to uniformly heat samples and for preparing scientifically used chemicals. The drawbacks of Bunsen burners i.e. open flame etc. are avoided by the use of these hotplates.

In present times Magnetic stirrer hotplate are also available which allows the automatic stirring of the liquid getting heated on the hotplate. Multiple position hotplate stirrers are also available for time saving and fast operations which contains multiple hotplates that are separately controlled.

How To Choose Hotplate Magnetic Stirrer from Different Types of Hot Plates?

Hotplate Magnetic Stirrer

A hotplate is a portable device that usually has up to two gas burners. Although the highly portable ones will have only a single burner and the bigger ones can have more than two burners. The type of burners can differ too, for some it may be a heating element (electric too). The portable versions are small self-contained table top appliances and can used as a standalone device. The most practical use of a hotplate is for the preparation of food in places where a kitchen stove is not practical to install. The added advantage being that a hot plate is highly portable and hence can transported easily.

Laboratory Hot Plates:Laboratory Hot Plates

The hot plates that are used in the laboratory are for a different purpose that the industrial ones. For example they are used to heat glassware or the contents. In addition to which there are several other types of hot plates that also have additional features and be useful as a magnetic stirrer. Thus the heated liquid can also be stirred with ease.

There are generally two main methods used to heat glassware in a laboratory as mentioned here:

Suspending Glassware: This is a novel method of heating glassware without direct contact. The glassware is suspended slightly above the hotplate surface. The main purpose being to reduce the rate of heating of the glass which effectively results in uniform heating. Although this cannot be used for all the substances and is mainly useful for substances with a low boiling point.

Teepee Setup: This method also includes suspending the glassware or flask above the hotplate and then surrounding it by a skirt of tinfoil. This tinfoil has to be arranged such that it starts at the neck of the flask and drapes down to the surface of the plate. This is arranged such that it covers the majority of the plate surface. This method is implemented if the glassware is to be heated at a higher temperature.

These are economical methods of heating the glassware and at the same time there is no need to wait and use a bath to cool it down later. Thus it is usually implemented in a student laboratory.

Industrial Hot Plates:

The hot plate is also used for several industrial applications and are available in several sizes like from 2 to over 300 square cm. The operating temperature of the device varies between 100 to 750 degrees centigrade. The power requirements of the device range from 120 volts to 480 volts. Since it is for industrial purpose it can withstand a heavy load of more than 150lbs.

There are industrial hot plates available for a special purpose that are often referred to as heated chucks. There are usually for industrial purpose and incorporate a porous heated plate. The way this works is the plates are used to heat thin films evenly by drawing the film firmly on the plate with a vacuum. This is a very popular with the manufacturing of semiconductors.

In addition to this the hot plates that are used in the chemical industry which make use of toxic chemicals are referred to corrosion resistant hot plates. These hot plates make use of special protective coating which is generally used in mining.

There are several other industrial applications of a hot plate like in the electronic industry for soldering and desoldering components, to fuse plastic pipes (butt fusion), etc.

An introduction to Magnetic Stirrer and brief information about the general assembly

The Magnetic Stirrer is commonly found in chemistry and biology laboratories since it serves a vital function that is required for several experiments and processes.

Magnetic Stirrer

This instrument is also referred to as magnetic stir plates; hence in case you were wondering “what is stirrer” you can rest assured it is the same as a magnetic stir plate.

Know that we know what is a stir plate, we can take a look at some more details about the device.

More in-depth look at what is a stirrer:

  • The main purpose of a magnetic stirrer is to mix several substances, either solids or liquids which results into a homogeneous liquid mixture.
  • Some of the practical uses include bacterial growth and also buffer solutions.
  • The magnetic stirrers work in a unique method using an external magnetic field. This external magnetic field rotates the small magnetic bar that needs to be placed inside the mixture. This causes the rotation to occur.
  • One the main advantages of using a magnetic stirrer is that there is almost no risk of contamination occurring.
  • There are several substances that require to be mixed for considerable amount of time like 5 to 10 hours. It is hard to achieve such a feat of consistent speed and good stirring for so long on a manual stirrer.
  • A magnetic stirrer can be setup with the necessary substances to mix and allowed to run unattended. This means that the long mixing process can even be done overnight (which saves time) and is more efficient.

Brief introduction into the assembly of a Magnetic Stirrer:

Magnetic Stirrer

  • The first step is motor assembly which involves using a motor, a hardboard and the magnet. The magnet is attached to the motor with the help of a hardboard.
  • The motor needs to be put in place in the right manner using the right screws and frame since it is vital that it remains in place when operational.
  • The second module is the speed control of the motor. The circuit for this is available and can be prepared on a PCB along with the necessary components.
  • Next comes the installing the battery and the LED.
  • Then comes the final assembly that include putting all together.
