A sampling tube, also known as a sample tube or test tube, is a cylindrical tube typically made of glass or plastic used to collect, store, and transport samples in various scientific and medical applications. Sampling tubes come in different sizes and shapes, with capacities ranging from a few milliliters to several liters. They are commonly used in chemistry, biology, environmental science, and other fields that require the collection and analysis of samples.
Sampling tubes are designed to be compatible with different types of samples, such as gases, liquids, or solids, and can be used for various applications, including collecting and storing blood, urine, saliva, or other bodily fluids, as well as environmental samples, such as air, water, soil, or sediment. They can also be used for the preparation of samples for microscopy, chemical analysis, or other diagnostic tests.
Sampling tubes can have different closure mechanisms, such as screw caps, snap caps, or stoppers, to ensure a tight seal and prevent sample contamination or evaporation. They can also be labeled with barcodes or other identifiers to facilitate sample tracking and management.
