Some Heat Sources used in the Common laboratory apparatus?

  • Alcohol lamp
  • Bunsen burner
  • Hotplate

Bunsen Burner

Bunsen-burner

The Bunsen burner is a heat source or mechanical device, it must be absolutely safe when using the Bunsen burner.

The use of Bunsen burners in the laboratory is related to combustible gases. Typically, a knob is used to adjust the gas flow, and an axle ring is used to control the gas flow. Both the knob and the collar must be adjusted so that the hot object produces a good flame.

Tripod stand

Tripod stand

It is usually made of stainless steel or aluminum with three supporting legs. Place the device on the tripod to warm up. During the experiment, it is mainly used to support or fix beakers or flasks. Due to its height, the Bunsen burner is located under the tripod.

Laboratory Equipments

1.Wire Gauze

Wire Gauze

It is a piece of iron wire with asbestos pasted in the middle. Place it on the tripod so that the flame does not touch the glass apparatus directly, which will reduce its risk of breaking.

2.Test Tubes

Test Tubes

A test tube is a glass tube with one end closed and the other open. The closed-end is round. The laboratory uses test tubes to hold small samples. They are mainly used for qualitative comparison and evaluation. Biochemistry is a very common phenomenon in the laboratory using a test tube to visualize a laboratory test tube. When a large number of samples need to be compared and tested, these test tubes can be used to simplify operations. They are also easy to cover or cover with glass or rubber stoppers.
Safety tips: Do not heat test tubes with or without caps

3.Beakers

Beakers

Beakers are a very common laboratory instrument and are widely used as reaction vessels in laboratories. They are also used to hold liquid and solid samples, or to collect liquids from various titers or to filter through filtration operations.

In most laboratories, the beaker is simple. Used for heating, stirring, and mixing chemicals. Most beakers have a spout at the rim, which can be easily inserted into the beaker for laboratory purposes. They usually have lips around their edges and have scars to measure the amount of liquid contained. They are not suitable instruments for measuring liquids. Depending on the size, different types of beakers can be used, such as 50cm3, 100cm3, 250cm3, or 500cm3.

4. Titration Flasks

Titration Flasks

It is also called Erlenmeyer flask. The Erlenmeyer flask was invented in 1861. Its neck is very thin and widens at the bottom. This makes the flask easier to rotate and mix without the possibility of overflow. The narrow opening also allows the use of glass or rubber plugs. It can be comfortably affixed to the ring frame and can be easily shaken or heated. Titration bottle

Again, the side numbers are mainly for estimation rather than accuracy.
An important safety note is not to heat the flask after it is capped. This can cause pressure to build up, causing an explosion.

5.Funnels

Funnels

The laboratory funnel is similar to any other funnel, but is specifically designed for use in the laboratory. They are made of glass or plastic and have long or short stems depending on the purpose. Many sizes have to be chosen, depending on the amount of liquid that needs to pass through the funnel easily and quickly. Funnel sizes are 3 cm, 5 cm, 8 cm and so on.

6.China Dish

China Dish

It is a small plate made of porcelain, which is used to evaporate and concentrate the dilute solution. It has different sizes.

7.Measuring Cylinders

Measuring Cylinders

For any liquid volume, it is an essential measurement device. There are many special markings above and below the entire length of the container. The measuring cylinder comes in many sizes. The smaller their size or diameter, the more accurate the measurement is. Measuring cylinder

When you look at the volume of a graduated cylinder, you will think that the liquid appears to be slightly sunken. The liquid around the edge of the measuring cylinder will be higher than the liquid in the center. It is called meniscus. To properly read the volume, place the cylinder on a level surface.

Different sizes of 5cm3, 10cm3, 20cm3, 50cm3, 100cm3 and 1000cm3 are also available.

8.Volumetric flasks

Volumetric flasks

A volumetric flask is a round flask that has a flat bottom and a long neck. Volumetric flasks are used to measure the precise volume of liquids. There is a small line on the neck, suggesting how far the flask can be filled. Provide a special bottle cap that will not allow anything inside and outside the flask.

Just remember: the temperature of the measuring flask determines the volume; Therefore, always avoid liquids that cause temperature changes (such as hot water that will cool).

They have different sizes, namely 100cm3, 250cm3, 500cm3 and 1000cm3.

9.Buret

Buret

Burettes are commonly used to add precise and precise volumes of liquid. With the help of a diuretic, you can measure or determine the amount of liquid up to 0.01 mL. These are usually fixed on the ring frame by clamps. Diuretics are also like glass tubes. It opens from the top and has a narrow pointed shell at the bottom. Just above the bottom opening, there is a plug valve. The stopcock can be turned on to control the amount of liquid released. There are also marks along the length of the diuretic, indicating the amount of any liquid present in it.

In particular, diuretics are used to properly add liquid. By adjusting the diuretics stopcock slightly, the amount of liquid released can be reduced to a drop every few seconds. Diuretics are one of the most accurate instruments in the laboratory.

10.Pipettes

Pipettes

There are a variety of pipettes designed to achieve any specific goals. However, both of these are used to measure the exact amount of liquid and then pour the liquid into other containers.

Commonly available sizes are 10cm3, 20cm3 and 25cm3.

11.Thermometer

Thermometer

Use a thermometer to measure the temperature of the substance. The temperature in the laboratory is usually measured in degrees Celsius (.C).

12.Watch glasses

Watch glasses

The clock glass is just a little convex round glass. It can hold small amounts of solid or liquid. Watch glass is used for evaporation and can also be used as a beaker lid.

13.Iron stand

Iron stand

A typical retort frame has a heavy base and vertical rods, usually made of metal. Many devices (such as various types of clamps and iron rings) can be fixed from thumb to pole without using any height and orientation to support the target device.

14.Wash Bottle

Wash Bottle

Nowadays, polyethylene washing bottles are used in laboratories to store distilled water for various operations, such as transferring sediment from containers to filter paper or washing off sediment. When you press the bottle with your hand, the water will flow out of a tube.

15.Florence Flask

Florence Flask

It is also called boiling flask. Under the Florentine flask is a round neck. It is used to hold liquid and is easy to heat and penetrate. It can also be easily covered with a glass or rubber stopper.

Once again, safety requires that the flask is never heated when it is capped or capped. This can create pressure and cause an explosion.

16.Test tube stand

Test tube stand

It is made of wood, polyethylene or steel, and the test tube can be placed directly over it. Test tubes are usually placed in a test tube rack. The test tube rack is specifically designed for this purpose. If these test tubes are exposed to bare hands (in case of heat or other reasons), use a test tube clamp to move them.
