The Cole-Parmer Screw Cap, 10 mm, Pre-Slit Silicone/Blue PTFE (98704-06) is a black polypropylene vial closure supplied with a pre-slit white silicone/blue PTFE septum. Designed for compatible chromatography vials, this 10 mm screw-cap configuration supports secure sample sealing while the pre-slit septum helps prevent vacuum formation inside the vial.
Key Features
- 10 mm screw-cap configuration, providing the specified closure diameter for compatible chromatography vials
- Black polypropylene construction, combining a lightweight polymer cap with the specified black colour
- Pre-slit silicone/PTFE septum, using white silicone with a blue PTFE layer and integrated slit
- Pre-slit design helps prevent vacuum formation, supporting smoother sample withdrawal from the sealed vial
- Secure vial-septum-cap sealing, helping reduce sample evaporation associated with inadequate closure sealing
- Non-sterile configuration, suitable for analytical workflows that do not require sterile vial closures
- Pack of 1000 caps, supporting routine and high-throughput chromatography sample preparation
Benefits
- Help maintain sample integrity with a secure cap and septum combination for compatible chromatography vials.
- Reduce the potential for vacuum formation during sample withdrawal through the pre-slit septum design.
- Support autosampler needle access without requiring the septum to be manually pierced before use.
- Reduce sample loss associated with poor vial sealing when the cap is correctly fitted.
- Maintain a high-volume supply for routine analytical workflows with 1000 closures per pack.
