Micro Insert suit for 2ml HPLC Vials

Screw thread vials and caps provide low evaporation, reusability, less hand injury during manipulation than crimp seals and require no special tools. All screw threads vials and caps are differentiated by their thread finish as defined by the Glass Packaging Institute, GPI. For screw thread vials, a two part number is assigned. For example, 8-425 neck finish represents a vial with a diameter of 8 mm across the outside of the threads and a thread style of 425. Screw thread vials and caps are more expensive than crimp seals.

Aijiren’s CA Syringe Filter 90% is exported to the world’s major economically developed countries. Filters can provide foundry services according to customer needs. The produced filters have good consistency between batches, and there are strict control procedures from raw materials to production processes to in and out of warehouse delivery management to ensure the quality and use value of the products.

The 20ml screw threaded headspace vial is used for the threaded vial (10ml + 20ml) and magnetic screw cap of CTC and TriPlus autosampler. It is easy to use and does not require any other tools. Samples can be transferred on site, without the need to transfer samples in the laboratory. The precise thread ensures the air tightness between the vial and the cap. Magnetic nut can be widely used in various SPME and headspace analysis. The round bottom vial is stronger, has higher pressure resistance when heating the sample vial, and is easier to slide into the heating hole.

The caps of the sample storage bottles are packed with septa, each with 100 pieces. The vial has been certified and can be used immediately. Each sample bottle is tested and certified.

20mm crimp-top headspace vials are a type of laboratory vials commonly used in gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) applications.
These vials are specifically designed for the analysis of volatile compounds in samples.
Headspace analysis is used when analyzing volatile or semi-volatile compounds that can be released from a solid or liquid sample into the gas phase.
This technique is particularly useful for samples that would be difficult to directly inject into a GC system or when analyzing volatile compounds in complex matrices.

The Aijiren 15x45mm vial has a 13-425 GPI thread that can hold up to 4ml of samples. Use a 13 x 425 cap with a septum when using it as a sample vial, or a diffusion cap for a cleaning vial. Sealed screw seals allow these vials to also be used as storage vials.

Aijiren¡¯s PP syringe filter uses a hydrophobic polypropylene membrane, which has stable physical and chemical properties, good compatibility, low protein adsorption, and is suitable for filtration of aqueous solutions and most solvents. Commonly used to filter biological samples, solvents, deionized water and reduce biological load, the hydrophobic PP filter membrane is particularly good for gas filtration. The product was sterilized by dry heat at 121¡ãC for 15 minutes.

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.

Aijiren began to produce Autosampler Vial 20 years ago, which is often used in chromatographic analysis experiments. Aijiren uses machinery for mass production, which ensures the mass production of products. 100 pcs/pack is convenient for customers to use. The design of separate packaging for Vial and Cap. It is convenient for customers to seal after holding Autosampler Vial.

Bonded Caps & Septa effectively eliminates needle shedding and prevents septum shedding
The cover pad is integrally formed, ready to use
Pre-slit is good for needle push-through

Aijiren’s Sample Storage Vial uses high-purity borosilicate glass to be manufactured in the most advanced molding equipment. Used to store PCR reagents, enzymes and other diagnostic reagents, as well as biochemical reagents or samples. The HDPE screw cover is leak-proof. Can be used at low temperatures. Amber Storagr vials can be used for light-sensitive samples.
Sample Storage Vial uses type 1, type A, 33 expanded borosilicate glass or 51A amber glass for storage glassware, with a capacity ranging from 20mL to 60mL, providing a constant pH value to extend the storage life of the sample, chemically inert lid Suitable for most chromatography and storage applications, top PTFE/silicone septa for cleaning

Ensure the integrity of your high-performance liquid chromatography (HPLC) samples with our premium-quality polypropylene (PP) caps, designed and manufactured in China.

Aijiren is a manufacturer specializing in the production of Autosampler Vial. It is precisely because of Aijiren’s expertise that it has its own production base and production line, which can guarantee large base production while ensuring quality. Aijiren’s quality inspection system is very strict. Aijiren’s staff will be in Via There are dozens of inspection procedures in the production process to carry out quality inspections, and you can rest assured to purchase Aijiren’s Autosampler Vial.

Chemical oxygen demand is a vital test for assessing the quality of effluents and waste waters prior to discharge. The Chemical Oxygen Demand (COD) test predicts the oxygen requirement of the effluent and is used for monitoring and control of discharges, and for assessing treatment plant performance. The impact of an effluent or waste water discharge on the receiving water is predicted by its oxygen demand. This is because the removal of oxygen from the natural water reduces its ability to sustain aquatic life. The COD test is therefore performed as routine in laboratories of water utilities and industrial companies.

Snap seal vials are less prone to breakage during decapping because more glass is used in the neck of the vial. The snap seal neck finish is compatible with either crimp and/or snap seals and no special tools are required to remove the cap. These vials are recommended for short term sample storage and non-volatile samples because the seal is not as secure as a crimp or screw thread seal.

There are many differences between butly rubber and natural rubber. The main advantage is that butyl rubber has better chemical stability and aging resistance than natural rubber. It has the elasticity of natural rubber and contains no protein components, but not butyl. Chemical Stability and Aging Resistance

The Aijiren 2ml crimp autosampler vial requires an 11mm crimp finish and requires an aluminum seal closure. Crimping aluminum caps are superior seals than screw caps and snap caps. In addition, crimp caps are resistant to high temperatures. However, a 2ml crimp autosample vial requires tools to seal the vials. This can increase costs. Aijiren is a 2ml crimp top autosample vial manufacturer. If you are buying a 2ml crimp top autosampler vial, you can get it from Aijiren at wholesale prices. Welcome to contact us.

Aijiren’s 20ml Headspace Vial has a specification of 22.5*75mm. It has two colors, clear and amber. The glass type of precision screw headspace vial is 5.0 type, but 20ml clear precision screw headspace vial has a type with or without label area.

Reagent bottles are made of borosilicate glass or soda lime glass with stoppers or caps to prevent spillage of contents or contamination from external environments. Reagent bottles are ideal for storing powders and liquids. Amber or red reagent bottles protect the photosensitive contents from UV, visible and infrared radiation.
