Disposable lab reservoirs are plastic containers used in laboratory experiments to hold and contain liquid reagents and solutions. These reservoirs are typically made of clear, durable polypropylene or polystyrene, which are resistant to chemicals and heat, and can be autoclaved for sterilization. Disposable lab reservoirs are available in multiple sizes, shapes, and volumes to meet the specific needs of different experiments. They are commonly used in molecular biology, immunology, microbiology, and other fields that require accurate and precise dispensing of liquids. As they are disposable, these reservoirs eliminate the risk of contamination, simplify cleaning procedures, and save storage space.
