Laboratory equipment and name

The pictures and names of laboratory equipment are as follows:

Erlenmeyer flask

Conical bottles are also called conical bottles or triangular bottles. The bottom of the main body is big and the mouth is small. After the solution is filled, the center of gravity is low, which is very convenient for hand-held oscillation, so it is often used as a titration container in volumetric analysis. Laboratories also use it to assemble gas generators or wash bottles.

wild-mouth bottle

A jar is a glass container for solid reagents, which is transparent and brown. Brown bottles are used to hold reagents (such as silver nitrate) that need to be protected from light. Wide-mouth bottles are generally used to store reagents, and the inside of the bottle mouth is frosted to match the bottle stopper.

Evaporating dish

A container for evaporating concentrated solutions or burning solids. Big mouth and shallow bottom, round bottom and flat bottom with handle. The most commonly used evaporating dish is porcelain, but it is also made of glass, timely and platinum. Different materials have different corrosion resistance and should be selected according to the properties of solutions and solids. Good stability to acid and alkali, high temperature resistance, but not suitable for quenching.

spirit lamp

Alcohol lamp is a kind of heating tool with alcohol as fuel, which is used to heat objects. Alcohol lamp consists of lamp body, wick tube and lamp holder. The heating temperature of alcohol lamp is 400-500℃, which is suitable for experiments with low temperature, especially without gas equipment.

drop bottle

When the amount of liquid chemicals used at one time is small or dangerous, drop bottles are usually used to hold the solution. Usually liquid acid-base indicator is used for dropping bottles. The inside of the bottle mouth is frosted, similar to a narrow-mouthed bottle, and the bottle cap part is replaced by a dropper. Most containers used to hold a small amount of liquid are used in the laboratory.
