Summary : Last week we talked about the classification of common equipment for chemistry lab, today we are going to talk about more about the reaction equipment in chemistry lab.

Last week we talked about the classification of common equipment for chemistry lab, and we have known that reaction equipment in chemistry lab is mainly used for chemical reaction, also includes a part of heating lab equipment, mostly are glass or porcelain equipment. It includes test tube, flask, evaporating dish, crucible and so on. Today we are going to talk about more about the reaction equipment in chemistry lab.

Test Tube

Test tube is the reaction vessel for small amount reagent, also can be used to collect gas. It can be divided into plain top test tube, welt top test tube and branch test tube. Plain top test tube is applicable for normal chemical reaction, welt top test tube always match use with a rubber stopper, branch test tube can be used as a gas generator or gas-washing bottle or distillation.

Beaker

Beaker is often used as the reaction vessel for large amount reactant, also used to prepare solution, speed up matter dissolution, promote solvent evaporation. The commonly used beaker volume such as 50mL, 100mL, 250mL, 500mL and so on.

Flask

Flask is the reaction vessel for large amount reactant, and the reactant needs to be long-time heated or react with liquid material. We often use round bottom flask and flat bottom flask. Round bottom flask often used under heating condition, and flat bottom flask often used as the as generator under non-heating condition.  

Distillation Flask

Distillation flask has a downward branch pipe on bottleneck, used to distill liquid. 150mL and 250mL are the two commonly used volume.

Conical Flask

Conical flask has longer bottle body, bottom is large while opening is small, often used as titration vessel in volumetric analysis. 150mL and 250mL are the two commonly used volume.

Retort

Retort is used as the reaction vessel or distiller. Simple structure is the most outstanding feature. 125mL, 250mL and 500mL are the three commonly used volume.

Kipp’s Apparatus

Kipp’s apparatus is named after a Netherlands chemist Kipp, he invented the equipment as early as 1862. When the reactant needn’t to be heated, and reactant is composed of massive solid and liquid, if you need to produce indissolvable gas, kipp’s apparatus is the best choice. 250mL and 500mL are the two commonly used volume.

Crucible

Crucible is porcelain equipment in chemistry lab, its function is firing and sedimentation. We often use 30mL in middle school chemistry laboratory.
