Black, Screw Neck Cap and PTFE/Silicone Septum, 100/pk
Waters Black, Screw Neck Cap is made and treated with chemically inert materials to ensure that no contaminants or impurities are present, yielding an interference-free result. These caps are extremely dependable and have a long shelf life for storing your sample and results while also protecting them from leakage. This septum is electron bonded to the cap and will not come loose during transportation or use.
For repeated injections and sample storage, the PTFE/Silicone septum is advised due to its excellent resealing abilities. Since it is initially chemically resistant before transitioning to silicone's chemical compatibility after being punctured, the PTFE/Silicone septum, which has a recommended operating temperature range of -40°C to 200°C, is appropriate for a wide range of applications. Waters vials and accessories are compatible with almost all HPLC systems due to their tight dimensional tolerances.
All Waters Black Cap and Pre-slit PTFE/Silicone Septum are made and handled with chemically inert materials to ensure there are no contaminants or impurities, allowing for interference-free results.

The Preparative Chromatography Standard contains Diclofenac sodium salt, Diphenhydramine hydrochloride, and Flavone in DMSO at a concentration of 5 mg/mL each. Utilize this benchmark mixture to verify the preparation or purification system's performance against industry standards. This QC Reference Material is a specially formulated blend of void markers and neutral, acidic, and basic compounds. It can be combined with a variety of column chemistries, dimensions, and system hardware.
What Is the Importance of Vial Color When Choosing Laboratory Equipment?
When choosing the best laboratory equipment for their lab's needs and experiment requirements, scientists must consider a number of factors. This is especially true when it comes to choosing the best chromatography vial for specific scientific requirements. Color matters because it affects the chemical stability of compounds and extracts. Waters manufactures clear and amber glass vials as well as plastic vials. An amber vial may be required depending on the contents to protect against UV light, which can damage certain chemicals. Amber vials are ideal for easily damaged chemicals, whereas Clear Vials give scientists the best visibility of chemicals.
