In HPLC analysis, the particle size of the chromatographic column packing is small and it is easy to be blocked by impurity particles. Therefore, samples and solvents need to be filtered in advance to remove particulate contaminants and protect the instrument. Ion chromatography, which is commonly used in environmental analysis, also requires that no inorganic pollutants be introduced in sample pretreatment. Syringe filters can be used in HPLC analysis and IC analysis to filter sample solutions, which is an important step in the sample pretreatment process.

These caps are typically made from high-quality materials such as polypropylene. These polypropylene caps have excellent sealing characteristics and offer good chemical resistance including acids, alcohols, alkalis, aqueous products, cosmetics, and household oils. Polypropylene Hole Caps are known for good impact strength, cost-effectiveness, and pliability.

In analytical laboratories, syringe filters are essential for ensuring sample integrity by removing particulates before analysis. However, filter breakthrough—where particles pass through the filter—can compromise results and damage sensitive instruments. Here are key strategies to prevent this issue:

Micro Insert is used to ensure the most accurate and reliable analysis of your lab samples. Micro-inserts are manufactured of clear glass. Micro inserts, when used in conjunction with autosampler vials, allow for maximum sample recovery and easier sample removal because the conical shape decreases the surface area inside the vial.
Micro inserts can be used with screw tops, crimp tops, or snap-top vials. All conical styles of inserts are offered with the traditional pulled point as well as the improved mandrel point. Pulled point inserts are more economical, but mandrel point inserts provide a more pointed and uniform tip that enables better sample recovery. Micro-inserts can be used on all 1.5ml vials. Effectively relieves the pressure of the syringe. PolySpring inserts are self-aligning.

Finding suitability to be used over a wide temperature range, these 1ml Shell vials come extensively tested so as to perfectly match up with the end user demands. Undergoing lab tests for ensuring defined quality standards. original shell vial for Waters 96-position autosampler. manufactured from superior quality borosilicate glass. 0.15 or 0.20 mL limited volume insert

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 10mm hplc vial features: all glass is made of material with 5.0 light transmittance, which is perfectly compatible with the instrument. 10-425 wide-mouth vial is similar to 8-425 small-neck vial, mainly used for Waters autosamplers and Japanese instruments , And the wide mouth can get a larger injection range, so this kind of bottle is often used to repeatedly clean the residual solution on the automatic injection needle.

EPA vials meet U.S. Environmental Protection Agency (EPA) requirements for testing water or soil samples for potentially harmful environmental contaminants.
If used for environmental analysis, EPA vials must be clean and free of substances that may affect the analysis. Glass vials that meet these requirements are called EPA vials, sometimes also called VOA (Volatile Organic Analysis) vials. EPA Vials are made of chemically inert Type I borosilicate glass in clear or amber colors.

Aijiren is the leading supplier of chromatography consumables, can offer hplc vials,hplc syringe filter, EPA VOA vials, and some other test tubes.
Any requirement for chromatography consumables, please contact us.

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. Teflon and silicone rubber or ultra-pure silicone are used as raw materials to ensure that the septa are non-toxic; to ensure excellent functions, it is particularly suitable for gas chromatography, and to ensure that the septum does not fall into the sample vial during the injection process.
The adhesive-free bonding process is used to combine the polytetrafluoroethylene membrane and the silicon rubber or silicone bond together to maintain the excellent characteristics of the two materials. The polytetrafluoroethylene layer of the composite septum is in contact with the reagent. It is chemically inert and resistant to acid, alkali, temperature, and adhesion. It does not work with concentrated acid, concentrated alkali, or strong oxidants even at high temperatures. At the same time, the elasticity of silicone rubber or silicone layer can ensure sealing performance.

This Amber Reagent Bottle is made from borosilicate glass and is great for containing liquids and powders that are light sensitive. When pouring hot liquids into an Amber Reagent Bottle or placing the bottle in the refrigerator, the lid should be propped open with a toothpick or other small object until the liquid and bottle are cool.

In HPLC analysis, the particle size of the chromatographic column packing is small and it is easy to be blocked by impurity particles. Therefore, samples and solvents need to be filtered in advance to remove particulate contaminants and protect the instrument. Ion chromatography, which is commonly used in environmental analysis, also requires that no inorganic pollutants be introduced in sample pretreatment. Syringe filters can be used in HPLC analysis and IC analysis to filter sample solutions, which is an important step in the sample pretreatment process.

Aijiren’s Snap Top Chromatography Vials are made of transparent or amber type 1 borosilicate glass (Grade A, 33 expanded borosilicate glass). The Snap Top Chromatography Vial can accept either aluminum snap-on seals or polyethylene snap-on caps. The colors are white, red, and blue. You can choose from them, which is very suitable for short-term storage.

Preassembled polypropylene snap-top closures with a 6mm center hole, including  PTFE/silicone septa. To use with 11mm snap-top vials. Snap caps provide a secure seal, minimizing evaporation even with volatile samples. Snap ring closures N11 should only be used in HPLC, as the punctual compacting pressure of the septum against the vial rim by the four pins in the cap does not achieve the same level of tightness as the evenly applied pressure through a screw thread or by crimping.

The material of 20ml amber vials is low extractable Borosilicate glass with low expansion rate, high-temperature resistance, high strength, high hardness, high light transmittance, and high chemical stability.

All of sample vial is on stock, you can get the HPLC vial in 7-10 days after you order. Welcome to inquiry.

Chromatography septas can be pre-slit. A pre-slit septum is an ideal choice in applications requiring 20% or more of the sample injection each time from the vial so that suction is avoided. The slit allows ambient gas to equalize the gas in the vial so that a vacuum is not created in the vial from the tight seal around the needle. If coring or clogging from a narrow needle or needle deflection from highly durable septa material is a concern, then choosing a pre-slit septum is a better choice.
A PTFE/Silicone with a slitted septum allows for easier needle penetration as well as to release the vacuum that forms when a large volume of sample is withdrawn from a vial. This septum provides chromatographic characteristics similar to that of a septum without a slit except that the ability to withstand exposure to aggressive solvents is slightly lessened. Pre-slit septa are highly recommended for improving injection-to-injection reproducibility with autosamplers withdrawing greater than 50µL of sample from a 2mL vial, due to possible cavitation (vacuum).

A headspace vial is used in the process of top – gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial.
