8-425 Screw Thread Cap And Septa (assembled)
The 8-425 Screw Thread Cap And Septa (assembled) from Ningbo Excellent New Material Co., Ltd. is a laboratory consumable designed for use with chromatographic vials and bottles. The assembly consists of a black open-topped cap and a white PTFE/red silicone septa, with a diameter of 8 mm. It is compatible with a range of vial models, including HM-4426, HM-4428, and HM-4429, and fits equipment from manufacturers such as Shimadzu, Perkin Elmer, and Varian.
The cap and septa are constructed from materials selected for chemical resistance and sealing integrity. The PTFE/silicone septa provides a reliable barrier against solvent leakage, while the screw thread design ensures a secure fit for high-pressure applications. Standard industry specifications for such components include a typical septa thickness of 1.0 to 1.5 mm, a temperature range of -50°C to 200°C for PTFE, and compatibility with common chromatographic solvents such as methanol and acetonitrile.
These consumables are primarily used in analytical laboratories for gas chromatography (GC) and liquid chromatography (LC) applications. Buyers typically order in bulk, with the minimum order quantity set at 100 pieces per pack. The assembled cap and septa are critical for maintaining sample integrity during analysis, making them a staple in research, pharmaceutical, and environmental testing facilities.

Sourcing 8-425 Screw Thread Cap And Septa (assembled) from Ningbo Excellent New Material Co., Ltd. - China Import Guide
Before placing an order, confirm the compatibility of the 8-425 cap and septa with your specific vials and chromatographic equipment. Request a sample to test the seal integrity and chemical resistance with your solvents, as even small variations in septa composition can impact performance. Verify whether the supplier provides certificates of analysis or compliance for the materials used.
Clarify logistics details, including lead times for bulk orders, which can range from 2 to 6 weeks depending on stock availability. Discuss Incoterms such as FOB Ningbo, and confirm whether the supplier can arrange consolidation for mixed orders. Payment terms are typically T/T, but negotiate partial payments for large orders to align with production milestones.
For quality assurance, inspect the caps and septa for defects such as cracks or deformations upon receipt. Test a sample batch for leakage under your typical operating conditions. Request documentation such as material safety data sheets (MSDS) and certificates of conformance. For critical applications, consider third-party testing to validate the septa’s performance with your specific solvents and equipment.
