pp cap

Caps for screw thread vials are available with either an open hole for autosampler use and standard addition or with a solid top for sample storage.

Polypropylene Screw Cap with Septa – Polypropylene screw cap with precision-fit septa provide an evaporation-proof seal. Bi-layer include silicone and PTFE. Silicone septa for multiple injections.

One piece polypropylene cap and membrane are also available. These pierceable screw thread caps are designed for one time use and reduce sample preparation time as there is no cap and seal to assemble.

PTFE-lined screw cap for organic samples. Screw caps provide an inert, airtight seal and direct puncture-access to samples with a syringe needle.

Polypropylene screw cap with septum-The polypropylene screw cap with septum provides an anti-evaporation seal. The double layer includes silicone and PTFE. The silicone septum can be injected multiple times. Screw caps lined with PTFE are used for organic samples. The screw cap provides an inert, air-tight seal and can be directly pierced through the sample with a syringe needle.

The threaded vial cap can have an opening for autosampler use and standard addition, or a polypropylene cap and membrane can be provided. These pierceable screw caps are designed for one-time use, and because there are no caps and seals to assemble, the sample preparation time is reduced.

The chemically inert lid used in the Sample storage vial is ideal for most chromatography and storage applications. Use top PTFE or silicone septa to ensure clean production and stable quality of sample bottles.

Caps are made of high quality polypropylene, Caps have the profile of a crimp or snap closure for compatibility with robotic autosamplers, Pre-assembled septa reduces the chance of contamination during sample preparation, while saving sample preparation time in the lab.

We provide the protection of PTFE and the resealing ability of silicone with our septa and seals to fit our autosampler crimp top vials. This seal includes a two sided PTFE septa with silicone in the center.

Polypropylene Screw Cap with Septa – Polypropylene screw cap with precision-fit septa provide an evaporation-proof seal. Bi-layer include silicone and PTFE. Silicone septa for multiple injections. PTFE-lined screw cap for organic samples. Screw caps provide an inert, airtight seal and direct puncture-access to samples with a syringe needle.

Polypropylene Screw Cap with Septa – Polypropylene screw cap with precision-fit septa provide an evaporation-proof seal. Bi-layer include silicone and PTFE. Silicone septa for multiple injections.

Polypropylene Screw Cap with Septa – Polypropylene screw cap with precision-fit septa provide an evaporation-proof seal. Bi-layer include silicone and PTFE. Silicone septa for multiple injections. PTFE-lined screw cap for organic samples. Screw caps provide an inert, airtight seal and direct puncture-access to samples with a syringe needle.

Our 9 mm wide mouth vials and caps are our recommended screw bottles. These vials are compatible with autosamplers and have an opening 40% larger than 8-425 threaded vials, simplifying pipetting and other routine functions. Aijiren Tech provides 9mm clear glass bottles and amber glass bottles, as well as polymer options and qualified glass bottles.

The screw cap produced by Aijiren is engraved with knurling on the side for excellent grip and comfort when applying it to a vial. The silicone rubber/PTFE septa used in the lining can provide an appropriate amount of resistance for the auto-injection needle during the sampling process, so that they can penetrate the sample bottle correctly without damaging the septum or the injection needle.

The 9mm screw vial cap can have a 6mm opening for autosampler use and standard addition, or it can have a solid top for storing samples. A polypropylene cap and diaphragm are also available. These pierceable screw caps are designed for one-time use, and because there are no caps and seals to assemble, the sample preparation time is reduced.

The polypropylene screw cap with diaphragm prevents evaporation and is highly sealed. The double layer includes silicone and PTFE. The 9mm screw cap has a shorter thread, which shortens the sealing time. The silicone septum can be injected multiple times. Screw caps lined with PTFE are used for organic samples. The screw cap provides an inert air-tight seal and can be directly pierced through the sample with a syringe needle.

Aijiren’s 8mm HPLC Vial and PP Cap are the best match for Shimadzu autosamplers. The opening is 8mm and the long thread design ensures the tightness of the cap when tightening. The center hole of the screw thread pp cap also ensures automatic Convenient access to the injection needle.

The 2ml glass hplc vial produced by Aijiren has a white pp cap. The white pp cap ensures the tightness of the thread seal. The center hole on the cap also ensures the stability and accuracy of the sampling of the automatic injection needle.

Aijiren’s 9mm Screw Cap is made of high-quality PP material, and the color can be customized according to customer needs. You can also choose whether to have a center hole. If you need to perform automatic sampling, it is recommended to use a Cap with a center hole to facilitate automatic injection needles sampling.

Polypropylene Screw Cap with Septa – Polypropylene screw cap with precision-fit septa provide an evaporation-proof seal. Bi-layer include silicone and PTFE. Silicone septa for multiple injections. PTFE-lined screw cap for organic samples. Screw caps provide an inert, airtight seal and direct puncture-access to samples with a syringe needle.

Polypropylene screw cap with septum – Polypropylene screw cap with precision fit septum provides anti-evaporation seal. Two layers include silicone and PTFE. Silicone septum for multiple injections. PTFE lining screw cap for organic samples. The screw cap provides an inert airtight seal and holes directly into the sample with a needle.

Snap cap vials have standard 12×32 profiles compatible with 11mm snap caps or 11mm crimp closures. Snap caps can be easily pushed or pulled by hand. 11mm Gc Snap Top Cap with Ptfe Silicon Septum for 2ml Snap Vial, 11mm Gc Snap Top Cap with Ptfe Silicon Septum for 2ml Snap Vial in SupplierAijiren Technology Co., Ltd.
