Brief Introduction Of Laboratory Consumables And Seven Categories

According to the 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 national food and drug administrations at all levels are all reagent consumables, and consumables that are not regulated as medical devices are all non-reagent consumables (details See the catalog of products not managed by the State Food and Drug Administration as a medical device).

According to the use and supervision methods of laboratory consumables, they can be roughly divided into seven major categories: 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 that are widely used in various experiments. Versatility is its most prominent feature, including glassware, quartz products, plastic products, and other utensils, such as tips, straws, test tubes, sample cups, etc.

(2) Cell culture consumables. Cell culture technology, also known as cell cloning technology, is one of the fastest-growing technologies in biotechnology in recent years. Special consumables such as cell culture dishes, cell culture flasks, cell culture plates, and cell scrapers used in cell culture experiments belong to cells. Cultivation consumables. The notable features of such consumables are sterile, DNA&RNA-free, pyrogen-free, 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 nature of life phenomena. At present, the most cutting-edge gene sequencing and precision medicine belong to the category of molecular biology, which is the discipline with the highest quality requirements for laboratory consumables.

(4) Consumables for microbiology experiments. Microbiology is one of the branches of biology. It studies the basic laws of life activities of various microscopic organisms at the molecular, cellular, or group level, and applies it to science in the fields of industrial fermentation, medical care, and bioengineering. Consumables commonly used in microbiology include Petri dishes, culture tubes, sampling tubes, inoculation loops, etc. Most microbiology consumables require sterility.

(5) Filtration/purification experimental consumables. It is mainly used for consumables for filtration and purification operations in experiments, mainly including filter paper, syringe filters, etc.

(6) Special consumables for instruments and equipment (special consumables for special planes). It mainly refers to the special measuring cup, cuvette or sample tip on the biochemical immunity and other inspection and testing equipment of a specific brand and a specific model, most of which are plastic products, and a few are quartz products. With the continuous improvement of the level of automation technology, many medical inspection items are increasingly completed by automated machines. 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. Traditionally, it only refers to collection and transportation devices, such as vacuum blood collection tubes, sampling swabs, virus sampling tubes, transportation media, etc., and does not contain microorganisms. The medium dish for culture. At present, the vacuum blood collection tube is one of the laboratory consumables with the largest single proportion of the laboratory consumables.
