Common chemical instruments and methods of use

(a) 1 capable of directly heating the instrument

Instrument graphics and name

[化] main application

Using methods and precautions

Used in evaporating solvent or concentrated solution

Can be directly heated, but not cold. Not too full evaporation solution, level should be 1 cm away from the edge.

Commonly used as a reactor, but also a small amount of gas

Direct heating, take a test tube, with the middle finger, index finger, thumb grasp tube mouth accounted for length of 1 / 3, heating pipe can not be against the people. In a test tube of liquid does not exceed V olume 1 / 2, heating is not more than 1 / 3 of the heating to test tube clamp, and the test tube with the desktop into a 45 degree angle, first to all the liquid heating, then in the bottom of a liquid heating and continue to shake. To solid heating tube to thwart mouth slightly downward tilt.

For burning solid, the reaction (decomposition)

Can be directly heated to a high temperature. When burning should be placed in the mud river, Schnabel. Application crucible should avoid cold gathering.

Burning a small amount of solid matter

Can be directly used for heating, met with Cu, Fe reaction material to spread fine sand or stone Mianrong. On the key pad

2 can be indirect heating (need to pad asbestos network)

Using methods and precautions

(501002505001000ml, etc.)

Used to prepare, concentrated, diluted solution. It also can be used as reactor and tube water bath heating.

When heating should be pad asbestos net

According to the volume of liquid with different specifications.

Used as a reactor (especially not heated).

Can not directly heating, heating, to the pad of asbestos mesh. Not suitable for long time heating, when the liquid in the bottle is too small, the heating is easy to make.

A reactor for use under heating conditions

Can not be directly heated, should be pad asbestos network heating. The amount of the liquid should not exceed the capacity of 1 / 2

For distillation and fractionation, also can be used as a gas generator

When heated to cushion asbestos net. Also available in other hot bath.

As the receiver

As a reactor, commonly used in titration operation

In general the asbestos net heating. In the titration operation in the liquid is not easy to spill.

3 unable to heat the instrument

[化] main application

Use method and matters needing attention

Used to collect and store a small amount of gas

Upper surface grinding, the inside is frosted, piece of glass to vaseline oil, to avoid leakage, if in the combustion reaction and formation of solid, add a small amount of water or fine sand in the bottom.

Packaging various reagents, need to be protected from light brown bottle. The jar containing solid, narrow necked bottles containing liquid.

Medial frosted bottle, and are in one-to-one correspondence with the bottle stopper, must not cover wrong. Glass Saibuke containing alkali, dropping bottle not can be long home strong oxidant etc..

Reactor solid + liquid for producing certain gases

The solid is a massive, gas is dissolved in a small reaction with no strong heat release, the rotating gas guide pipe piston control reaction or stop.
