Aijiren Provide Chromatography Consumables since 2009

PP housing membrane syringe filter refers to a syringe filter wif a housing made of polypropylene (PP).

Polypropylene is a commonly used material for syringe filter housings due to its chemical compatibility, low extractables, and resistance to a wide range of solvents. PP housings provide structural support to teh filter membrane and help maintain its integrity during filtration.
These syringe filters find applications in various fields such as pharmaceuticals, biotechnology, environmental analysis, food and beverage testing, and research laboratories where precise filtration is required to ensure sample purity and integrity.

Reagent Bottles, also known as Media Bottles, are manufactured from high quality borosilicate 3.3 glass with a GL45 threaded cap. With their superior chemical resistance, these bottles are ideal for storing reagents, culture media, biological fluids, and a variety of other aqueous and non-aqueous solutions.

Our vial comes with a variety of septa options to suit your specific application needs. Whether you require septa with different materials, thicknesses, or properties, our Autosampler HPLC Vial provides versatility and customization. Select the ideal septa option to ensure optimal sample protection and compatibility with your analysis requirements.

Borosilicate glass vials are commonly used in UPLC (Ultra Performance Liquid Chromatography), HPLC (High Performance Liquid Chromatography), GC (Gas Chromatography), and LC-MS (Liquid Chromatography-Mass Spectrometry) applications.

Screw cap vials are universal. When screwing on the cap, a mechanical force is applied that compresses the septum between the rim of the vial and the cap. Screw closures provide an excellent seal and mechanically hold the septum in place during piercing. No tools are required for assembly.

These vials have an internal tapered bottom which allows the contents to be concentrated at the bottom. Allows more space and larger volumes than concentrating to very small quantities. Ideal for derivatisation or target compounds with very low target concentrations.

Snap Cap Vials Wide opening vial is easier to fill and provides a larger target area for the autosampler needle Fit most autosamplers that accommodate the 12x32mm vial format Superior quality 33 expansion borosilicate clear glass Type 1, (Class A) or 51A amber glass Uniformly flat

The reagent bottle can withstand a low coefficient of thermal expansion (3.3), and its heat resistance is far better than standard laboratory glass (or soda lime glass). Aijiren glass can withstand temperatures from -70 to 500°C, so it can be reused in freezers, microwave ovens, autoclaves and dry heat sterilizers.

HPLC sample vial Septa is one of the most important part in chromatography consumable. Septa for HPLC has high temperature resistance and corrosion resistance. Quality and service in a controlled production environment is trusted by customers. The Caps are made of high quality polyproylene to exact manufacturing tolerances and lined in a controlled manufacturing environment, The color of the #HPLCvial cap can be customized according to customer needs. Aijiren’s septa use only the highest quality materials to ensure proper function and can be pre-slit to ease needle penetration.

In addition, the material of Butyl determines that Septa is not easy to deform, even if it is used for a long time, it is stretched. Aijiren uses high-quality raw materials, which ensures that Butyl Septa will not break and contaminate the sample when it is penetrated by the automatic injection needle in time.

2ml Crimp Autosampler Vial with insert is larger and wider mouth than 9mm screw sample vial. 2ml crimp autosampler vials have approximately a 40% wider mouth opening than standard opening vials. The large opening reduces the risk of bent autosampler needles during sampling.

An 11 mm vial crimper is a tool used to seal or crimp aluminum seals onto 11 mm vials. These vials are commonly used in chromatography applications, such as HPLC (High-Performance Liquid Chromatography) or GC (Gas Chromatography), for sample storage or analysis.The crimper enables the manual crimping of the cap onto the vial to create a secure and airtight seal.

Aijiren offers a variety of sizes and styles of containers, including the popular 40mL autosampler vials. Sample Storage Vial can be used as: Sampling and storage containers, sample vial compatible with autosampler, culture tube, TOC test, USP Method 643 test, Capture high-purity water offline, Store verification standards.

The 150ul, 250ul, and 300ul Micro Inserts for HPLC Autosampler Vials provide precise sample volume delivery for accurate and reproducible analysis. These inserts are specifically designed to fit inside standard HPLC autosampler vials, allowing for controlled sample introduction with minimal dead volume.

How to choose a precise syringe filter: Aijiren disposable syringe filters come in many types. There are mainly two series, one is hydrophilic and the other is hydrophobic series. The syringe filter has two diameters: 13mm and 25mm. The pore size of the filter membrane is 0.22, 0.45um. Membrane materials include: RC, nylon, PVDF, PTFE, etc. It is important for customers to choose the right membrane.

The 1ml Shell Vial produced by Aijiren is mostly used in experiments with few samples but precious. This type of Vias is sealed with PP Cap. The glass is stable and highly inert, and it is not easy to affect the quality of Vias due to the chemical content.

The 13mm autosampler vial is produced by Aijiren using high-quality imported raw materials from abroad, with high temperature resistance and corrosion resistance; the cap is made of high-quality polypropylene, and the septum is made of the highest quality materials, with precise manufacturing tolerances. , The controllable manufacturing environment ensures the high efficiency of product functions. It is widely used in the design of multiple injections or longer sampling periods, as well as weather chromatographs and liquid chromatographs.

The shell of PTFE Syringe Filter is made of polypropylene (PP) with excellent chemical stability. It is made of different colors, which is convenient for users to distinguish products of different materials and avoid confusion. The filter membrane adopts imported high-performance filter membrane with stable product quality and good reproducibility. It is an ideal choice for laboratory filtration of samples. The standard interface is convenient to connect to various syringes, and it can also be directly connected to the needle of the 7725 valve, and the sample can be injected directly after filtration.

Hydrophobic PTFE (Polytetrafluoroethylene) syringe filters are suitable for gaseous and organic solutions, with excellent performance for high corrosive samples. It is possible for an extended sampling range using hydrophobic PTFE filters for wider chemical resistance to aggressive substances and outstanding temperature stability. A PTFE syringe filter is an ideal choice for filtering and de-gassing chromatography solvents.
