Combine PTFE Septa and 9mm Screw Cap

Screw storage vials are suitable for the packaging of various pharmaceutical intermediates, high value-added chemicals, chemical reagents, biological reagents, cosmetics, essences and oils, etc. It is suitable for long-term storage and transportation for products, and has excellent sealing performance.

In the field of experimental consumables, glassware consumables account for 86%. Reagent bottles are widely used for reagent storage and transport, accounting for only 32% of the final glassware. 2ml HPLC vials are widely used in chromatography, accounting for 54% of glassware consumables. This shows that the demand for the 2ml HPLC vial market is very large.

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 aijiren chromatography sample vial is made of borosilicate glass and meets ASTM TYPE I ClassA and USP TYPE I standards.
There are four types: colorless and amber vial, handwriting area and no handwriting area.

The sample storage vial is a storage glassware made of type 1, type A, 33 expanded borosilicate glass or 51A amber glass, with a capacity from 20mL to 60mL. The chemically inert lid is suitable for most chromatography and storage applications. The top PTFE / Silicone septa for cleaning

Aijiren’s Headspace Caps often use metal material aluminum, which is soft and convenient for Hand Crimper and Decrimper for sealing. Not only that, the Septa produced by Aijiren is also made of high-quality silicone and ptfe, and is pressed with an exclusive process. This kind of septa is not easy to deform, break, and fall off, and it can also ensure the tightness of the vial.

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.

Aijiren’s chromatography bottle has a wide-mouth crimp cap that provides a larger target area and improves the accuracy of the autosampler needle. Can be made of clear and amber glass. The label can be written area, can help the experimenter to distinguish the sample type.

HPLC autosampler vials  are generally categorized by vial diameter, vial height, and thread finish. Clear glass and amber glass have similar inert properties. Amber glass is used to protect sensitive samples from UV light. 

150uL insert, with inner mandrel and polymer feet, 29 * 5mm; suitable for ND8 sample bottles. Glass insert with polymer feet. Cone, with a precision-shaped mandrel inside, 150μl. The spring insert can automatically adjust the center and provide cushioning for needle contact.

The non-pre-slit septas help to reduce carryover from vial to vial because the resealing characteristics of the septum act as a squeegee to wipe solution from the outside of the needle. Typically, a non-slit septum exhibits resealing capabilities for a limited number of needle punctures but for long-term storage in the vial, using a new non-punctured septum is best practice.

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.

Cellulose acetate is a very low protein binding membrane that is ideal for aqueous based samples and biological samples. It is a lower protein binder than either polyethersulphone or PVDF membranes, but has a lower chemical resistance than regenerated cellulose (RC). CA is a strong membrane mechanically and hydrophilic.

18mm Screw Neck Closures 18mm screw neck vials with magnetic screw seals for CTC is a new product in the headspace market where the jaws dominate. Especially for magnetic caps that are difficult to crimp, screw caps are a convenient alternative. 18mm Screw Neck Closures with Vial are preferentially used in instruments: CTC PAL, Varian, Gerstel, Atas, Shimadzu, Aijiren.

There are three types of 2ml HPLC Vials produced by Aijiren, Screw, Snap and Crimp Top. These three types of Vials can be used for autosamplers, but different bottlenecks are used with different types of machines, but these three types of vials The maximum capacity is 2ml, and you can choose vias with label area on the bottle.

13 mm 0.22 um syringe filters come in various sizes, pore sizes, and materials to suit different applications. It is important to select the appropriate filter based on the type of sample, the desired filtration efficiency, and the compatibility of the filter material with the solvent or solution being filtered.Syringe filters can remove particulate matter, debris, aggregates, colloids, bacteria, and other contaminants that may interfere with the analysis.

The Non-sterile Disposable Syringe Filter is a versatile filtration device used in laboratories for sample preparation and clarification. It consists of a polypropylene housing with a membrane filter, providing efficient filtration of particulate matter and microorganisms. These syringe filters are available in various pore sizes and diameters to suit different filtration needs, and they come in non-sterile packaging.

There are two types of packaging for 20mm Crimp Top Closures produced by Aijiren, one is packaged in plastic bags, the other is packaged in threaded plastic cans, and the quantity is 100 per bag/can. Aijiren is packaged in cans. Because 20mm Crimp Top Closures are easily squeezed and deformed during transportation, which affects the sealing effect in the experiment, they are packed in cans.

9mm thread caps, septums, 9mm 2ml HPlc screw vials are specifically designed for use with THERMO FISHER and other rotating or robotic arm samplers. 9mm2ml Hplc screw vials are manufactured in transparent glass, Type 1 Class A or Amber, Type 1 Class B borosilicate glass and contains a write patch for sample identification. Amber glass prevents exposure to UV light and protects sensitive samples.

Aijiren’s 2ml hplc vial adopts a fully automated production method, mass production guarantees a large amount of daily production, Aijiren has 6 vial production lines, and can also be customized for logo or label, scale printing, and closures. Aijiren Provide the option of purchasing vial/cap separately or purchasing vial and cap together.

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.
