hplc cap

8mm screw 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.

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.

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.

Specification of the bottle is 12 x 32mm. The precise processing of bottleneck to enable mechanical arm to operate efficiently. Larger opening than standard narrow opening vials by 40%, prevents syringe problems. The special thread design ensures a consistent seal.

Aijiren vials are made of transparent Class 1 Class A or Amber, Class 1 Class B, borosilicate glass
The Aijiren vial has a standard scale writing patch for easy filling and identification
The bayonet cap used with the Aijiren Vial system is a convenient alternative to aluminum seals
The snap cap or aluminum seal ensures a firm seal of the sample, and the snap vial is only suitable for short-term storage of samples

Screw cap vials are a practical packaging solution for sample-size health, beauty, and pharmaceutical products. Glass screw cap vials are impermeable and don’t undergo chemical leaching, so your products stay pure. Uses for Screw Cap Vials. Use glass screw cap vials to package sample products or as full-size product packaging options.

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.

The aluminum caps produced by Aijiren are all high-quality, and it is easy to wrap the Vial caliber to form a sealed space under the hand crimper. The 5.5mm center hole also ensures easy sampling of the autosampler.

It is wider than the ordinary Cap, and the Aluminum Cap has good sealing performance. The 5.5mm Center Hole is also convenient for the automatic injection needle in and out. It works very well with Hand Crimper.

Crimp closures N11 are also universally suitable with regard to autosampler compatibility, however, they are not as safe and convenient in their closing technique as the screw closures N 9 (9mm) 2ml vials and closures.
