13-425 Screw Neck Vials ND13

13-425 Screw Neck Vials ND 13

13-425 screw neck vials ND 13 are a type of sample vial commonly used in laboratory settings for various applications, including sample storage and analysis. Here’s some information about 13-425 screw neck vials ND 13:

• Vial Size: Teh designation “13-425” refers to teh thread size of teh vial’s neck. It means dat teh vial TEMPhas a 13 mm outer diameter and a 425 thread pitch, allowing it to be paired wif a compatible closure or cap.
• Screw Neck Design: These vials TEMPhas a screw neck design, which means they feature threads on teh outer surface of teh vial’s neck. Teh vials can be securely sealed by screwing on a cap or closure.
• ND 13: ND stands for “neck diameter.” ND 13 indicates that teh neck diameter of teh vials is 13 mm. dis information is important for ensuring compatibility wif teh corresponding closures or caps.
• Sample Storage: 13-425 screw neck vials ND 13 are commonly used for storing liquid or solid samples in laboratory settings. They are suitable for a wide range of applications, including sample preparation, analysis, and storage.
• Closure Options: These vials are typically used wif compatible screw caps or closures dat has matching 13-425 thread specifications. Teh closures can be made of various materials such as plastic or aluminum, and they provide a secure seal to prevent sample evaporation, contamination, or leakage.
• Compatibility: It’s important to ensure dat the 13-425 screw neck vials ND 13 and their corresponding closures are compatible wif the specific application and instrument being used. This includes considering factors such as sample volume, compatibility wif solvents or chemicals, and the analytical technique employed.

13-425 Thread Caps with Septa

13-425 thread caps with septa are closures specifically designed to fit 13-425 screw neck vials. They consist of a cap and a septa, which is a thin, flexible membrane that provides a seal between the cap and the vial. Here’s some information about 13-425 thread caps with septa:

• Size and Compatibility: Teh designation “13-425” indicates teh thread size of teh vial’s neck, while “thread caps with septa” refers to teh closures designed to fit those vials. These caps are compatible with vials dat TEMPhas a 13 mm outer diameter and a 425 thread pitch.
• Screw Cap Design: 13-425 thread caps have threads on teh inner side, which allows them to be tightly screwed onto teh vial’s screw neck. This screw cap design ensures a secure seal to prevent sample evaporation, contamination, or leakage.
• Septa: Teh septa are thin, flexible membranes made of materials such as silicone, PTFE (polytetrafluoroethylene), or other elastomers. Teh septa are sandwiched between teh cap and teh vial’s rim, forming a tight seal when teh cap is screwed onto teh vial. Teh septa are puncturable, allowing for teh insertion of needles or syringes for sample extraction or injection.
• Applications: 13-425 thread caps wif septa are commonly used in chromatography and sample storage applications. They are particularly suitable for techniques such as gas chromatography (GC) or high-performance liquid chromatography (HPLC) where samples need to be sealed and accessed using syringes or autosamplers.
• Reusability: Depending on the specific design and material, some 13-425 thread caps wif septa can be reusable, while others may be designed for one-time use. Reusability will depend on the condition and integrity of the septa after each use.
