1) Description
15-425 open screw cap is a vial cap specially designed for laboratory use and is suitable for various vials with 15-425 specification threads. The cap is available in polypropylene (PP) or polycarbonate (PC) and is available in black or white color options. The cap is designed with fine vertical stripes to enhance the grip and make it easier to open and close. The gasket material is PTFE and silicone, and can be selected with or without pre-opening to meet different sealing and sampling needs.
2) Application
• Chromatographic Analysis: The open top cap design allows samples to be injected directly through the syringe without opening the vial cap, which is suitable for experiments that require frequent sampling or adding reagents.
• High-precision Testing: The open top cap combines PTFE and silicone septa to provide excellent chemical inertness and sealing, ensuring that the sample is not contaminated by the outside world, and is suitable for chemical and biological testing that requires extremely high precision.
• Sample Preservation and Transportation: Especially suitable for sensitive samples that need to be stored or transported for a long time, such as biological samples, environmental samples, etc., the open top cap ensures the stability and safety of the sample throughout the process.
• Daily Laboratory Use: The easy-to-use design, including pre-slit septa options, allows laboratory personnel to quickly and safely access the contents of the vial, effectively improving laboratory work efficiency and safety.
3)Features
▶ Various Material Selection: Users can choose polypropylene or polycarbonate material according to needs to adapt to different environments and chemicals.
▶ Improved Sealing Performance: PTFE and silicone septa design provides excellent chemical inertness and temperature resistance, suitable for a variety of complex environments.
▶ Convenient Design: Pre-slit septa are suitable for applications that require frequent sample access, simplifying the operation process and reducing the risk of cross-contamination.
▶ Easy to Operate: The vertical ribbed design of the cap enhances the convenience of holding and operation, making it easy to open and close.
