Classification of Laboratory Consumables

According to relevant management measures, Laboratory Consumables are divided into reagent laboratory consumables and non-reagent laboratory consumables. Generally speaking, laboratory consumables that are medical devices and have obtained medical device registration certificates issued by the national food and drug regulatory agencies at all levels are all reagent consumables, and consumables that are not regulated as medical devices are all non-reagent consumables (detailed See the catalog of products not managed by the State Food and Drug Administration as a medical device).

According to the usage and supervision methods of laboratory consumables, it can be roughly divided into seven major consumables: conventional consumables, cell culture consumables, molecular biology experimental consumables, microbiology experimental consumables, filtration/purification experimental consumables, special consumables for instruments and equipment, and reagent consumables. kind.

(1) Conventional consumables. Conventional consumables refer to auxiliary consumables widely used in various experiments. Versatility is its most prominent feature, including glassware, quartz products, plastic products and other appliances, such as tips, straws, test tubes, sample cups, etc.

(2) Consumables for cell culture. Cell culture technology, also called cell cloning technology, is one of the fastest-growing technologies in biotechnology in recent years. In cell culture experiments, cell culture dishes, cell culture flasks, cell culture plates, cell scrapers and other special consumables all belong to cells. Training supplies. The salient features of this type of consumables are sterility, no DNA & RNA, no heat, etc.

(3) Consumables for molecular biology experiments. Molecular biology is a science that studies the structure and function of biological macromolecules at the molecular level, thereby clarifying the essence of life phenomena. At present, the most cutting-edge gene sequencing and precision medicine belong to the category of molecular biology. This field is a subject that requires the highest quality of laboratory consumables. Its commonly used consumables include filter tips, enzyme-free and heat-free tips, PCR plates, sealing membranes, etc. .

(4) Microbiology experiment consumables. Microbiology is one of the sub-disciplines of biology. It studies the basic laws of life activities of various micro-organisms at the molecular, cellular or population level, and applies them to the sciences of industrial fermentation, medical and health, and bioengineering. Commonly used consumables for microbiology include petri dishes, culture tubes, sampling tubes, inoculation loops, etc. Most of the microbiology consumables require sterility.

(5) Filtration/purification experiment consumables. It is mainly used for the consumables of filtration and purification operations in the experiment, mainly including filter paper, syringe filter, etc.

(6) Special consumables for instruments and equipment (special consumables for special planes). Mainly refers to the special measuring cups, cuvettes or sample tips on the biochemical and immunological inspection equipment of specific brands and specific models. Most of them are plastic products, and a few are quartz products. With the continuous improvement of the level of automation technology, many medical inspection projects are also increasingly relying on automated machines to complete. Therefore, special consumables for instruments and equipment will account for an increasing proportion of laboratory consumables in the future.

(7) Reagent consumables. Mainly refers to the laboratory consumables with the second or third type of registration certificate. In the traditional sense, it only refers to the collection and transportation device, such as vacuum blood collection tube, sampling swab, virus sampling tube, transportation medium, etc., and does not contain microorganisms A base petri dish for culture. At present, the vacuum blood collection tube is one of the laboratory consumables with the largest proportion in the laboratory consumables.
