2、 How to classify laboratory consumables

According to the use and supervision methods of laboratory consumables, they can be roughly divided into seven categories: conventional consumables, cell culture consumables, molecular biology experiment consumables, microbiology experiment consumables, filtration/purification experiment consumables, instrument and equipment special consumables and reagent consumables.

1. General consumables

Conventional consumables refer to auxiliary consumables that are widely used in various experiments. Generality is its outstanding feature, including glassware, quartz products, plastic products and other appliances, such as suction heads, straws, test tubes, sample cups, etc.

2. Consumables for cell culture

Cell culture technology, also known as cell cloning technology, is one of the fastest growing technologies in biotechnology in recent years. The special consumables used in cell culture experiments, such as cell culture dishes, cell culture bottles, cell culture plates, and cell scrapers, all belong to cell culture consumables. Such consumables are characterized by sterility, no DNA&RNA, no heat source, etc.

3. Consumables for molecular biology experiment

Molecular biology is a science that studies the structure and function of biological macromolecules at the molecular level, thus clarifying the essence of life phenomena. At present, the cutting-edge gene sequencing and precision medicine all belong to the field of molecular biology. This field is a subject with high requirements for the quality of laboratory consumables. Its commonly used consumables include filter element suction, enzyme-free and heat-free suction, PCR plate, sealing film, etc.

4. Consumables for microbiology experiment

Microbiology is one of the branches of biology. It is a science that studies the basic laws of life activities of all kinds of micro organisms at the molecular, cell or group level and applies them to industrial fermentation, medical and health care, bioengineering and other fields. Commonly used microbiological consumables include culture dishes, culture tubes, sampling tubes, inoculation rings, etc. Most microbiological consumables are required to be sterile.

5. Filtration/purification test consumables

It is mainly used as consumables for filtration and purification operation in the experiment, mainly including filter paper, needle filter, etc.

6. Special consumables for instruments and equipment (special consumables for special aircraft)

It mainly refers to the special measuring cup, colorimetric cup or sampling tip on the biochemical immunity and other inspection and detection equipment of specific brands and models, most of which are plastic products and a few are quartz products. With the continuous improvement of automation technology, many medical inspection projects are also more and more dependent on automated machines. Therefore, special consumables for instruments and equipment will account for an increasing proportion of laboratory consumables in the future.

7. Reagent consumables

It mainly refers to laboratory consumables with Class II or Class III registration certificate. Traditionally, it only refers to collection and transportation devices, such as vacuum blood collection, sampling swab, virus sampling tube, transportation medium, etc., and does not include media dishes for microbial culture. At present, vacuum blood sampling is one of the laboratory consumables with a single and significant proportion.
