Sampling vials play a vital role in the laboratory environment, enabling scientists and researchers to collect, store and transport various types of samples for analysis. To ensure the safe use of vials in the laboratory, proper handling and storage procedures must be followed.
Material Compatibility: Select vials made of materials that are compatible with the samples being collected or stored. Common materials include glass, polypropylene (PP), polyethylene (PE), or other chemically resistant plastics. Make sure the vial is suitable for the intended application and can withstand the chemical composition and potential reactions of the sample.
Quality Assurance: Use only defect-free vials that meet quality standards. Inspect the vial for cracks, chips, or any other damage that could compromise the integrity of the sample or cause a leak. Discard any broken or damaged vials to prevent contamination or accidents.
Clean Properly: Before using sampling bottles, clean them thoroughly to remove any contamination or residue that may affect the integrity of the sample. Follow established cleaning procedures, which may include rinsing with appropriate solvents, cleaning with detergents, or autoclaving. Make sure the vial is completely dry before use to prevent the introduction of moisture that could affect the sample or cause a reaction.
Labeling: Clearly label each vial with basic information, including sample identification, date, and any relevant handling instructions or precautions. Proper labeling ensures accurate identification of samples, prevents mix-ups, and facilitates proper storage and retrieval.
Aseptic technique: Where sterility is critical, the use of sterile sampling bottles minimizes the risk of contamination. Sterilization methods may include autoclaving, gamma irradiation, or sterile filtration. Adhere to an aseptic technique during sample collection, transfer, and storage to preserve sample integrity and prevent cross-contamination. Of course, there will be more requirements for the use of containers, not limited to the above points.
