The 18 mm threaded neck vial with magnetic screw seal for CTC is a new product in the headspace market dominated by pressure necks. However, especially for magnetic caps that are difficult to crimp, screw caps are a convenient alternative. Reproducible results are excluded because of improperly adjusted or non-adjustable crimpers caused by crimping errors.

Vials with septa-capped 18mm caps are used as sample vials, and these vials can also be used as storage bottles. Precision-machined threads always ensure sealing. It fits perfectly with the matching 18mm magnetic metal screw cap and PTFE/silicone septum. The caliber of this series of headspace bottles is 18mm, and the size of 20ml is 22.5*75.5mm.

The head space of the threaded mouth is easy to use, without tools, the Cap can be screwed directly on the bottle mouth; the risk of wrong clamping jaws is avoided, and the repeatability of the analysis results is guaranteed; the professional precision makes the gasket and the bottle mouth more sealed; Septa’s The thickness is less than the thickness of the jaw cover, making the puncture easier and safer; the sample can be taken out in the field without taking it out in the laboratory.

Aijiren usually packs 100 caps in a packaging bag, starting with a pack. Aijiren will choose the delivery method according to the quantity of products ordered by the customer. If the quantity ordered is small, it can be sent by express, and if the quantity is large, it needs to be transported by sea. If the customer is in a hurry, it can also be shipped by air.

The main material of Screw headspace sample vial is medical borosilicate glass. The vial body is annealed at a high temperature of 580 degrees Celsius, and the wall thickness is uniform, which can be used for high temperature sterilization. The vial cap is made of PTFE/silicone gasket and aluminum cap with holes. Clamping headspace vials are mainly used for liquids and powders that need to be sealed. The colors are mainly transparent colorless glass, amber glass and silver open-eye aluminum cover.

Aijiren’s professional precision makes the gasket and vial mouth more air-tight. The thickness of the diaphragm is less than the thickness of the jaw cover, which makes the puncture easier and safer. The sample can be removed in the field instead of in the laboratory.

The screw headspace series vial caps combine innovation with time-saving convenience, precise manufacturing tolerances and a controllable manufacturing environment. The vial cap produced by this patented method truly combines the diaphragm and the vial cap at the molecular level, thereby avoiding excessive evaporation and maintaining the correct seal of the sample vial.

10ml transparent precision spiral vial, 18mm round bottom, top space vial, strong adsorption. Suitable for automatic SPME, such as CTC Combi PAL, TriPlus, Shimadzu AOC5000, Agilent G1888A.

Aijiren Headspace Vial is compatible with most autosamplers on the market. The threaded sample vial is very convenient and safe to seal. There are two volumes to choose from, and there are two flat or round bottoms to choose from. Certified headspace crimp top sample vials, headspace vials and seals are packaged in one set.

Aijiren’s septa has a thinner thickness, uses high-quality raw materials and a non-sticky bonding process with good elasticity and sealing performance, making puncture easier and safer. It is especially suitable for automatic SPME applications.

The Aijiren headspace sample vial has a slanted neck to ensure a safe seal; the glass thickness is uniform for uniform heat distribution and stability; the sturdy design is easy to use. Supplied with transparent amber USP1 borosilicate glass with screws and crimp top. The round-bottom vial can disperse the internal pressure generated by the high temperature of the glass surface, and it is easier to handle the vials lifted from the tray by the robot. The screw-head empty vial has an 18 mm Aluminum Cap, which is suitable for autosamplers that use magnetic transmission.

18mm magnetic thread cap. It is easy to use and does not require any other tools, such as capping machine and cap opener. 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 threaded headspace vial is especially suitable for CTC Combi PAL, TriPlus and Shimadzu AOC5000 or other similar instruments. The design of the central opening can be used for SPME and also for headspace analysis, and still provides enough magnetic area to transfer the vial with the sample.

Headspace Vial is usually made of colorless glass, silver perforated aluminum cover, amber glass, PTFE/silicone gasket, butyl rubber stopper, etc. This series has good sealing performance and is used as a headspace sample vial. It is more convenient, safer, and ensures good repeatability of analysis results.

The headspace sample bottles produced by Aijiren can be made of clear or amber glass, with a round or flat base, and a threaded Cap treatment with beveled or square edges. The headspace bottle, septum and cap can be purchased separately or together as a convenience kit to meet the needs of your laboratory.

Aijiren’s headspace vials and sealing stoppers. Aijiren Technologies headspace vials and caps are carefully designed to prevent sample contamination and ensure accurate analysis. They come in various sizes and glass types. Choose crimping or threaded vials; the beveled top ensures maximum sealing safety.

Aijiren certified 10 mL and 20 mL screw styles, clear or amber glass headspace vials and related 18 mm headspace vials are carefully designed to prevent sample contamination while providing a consistent, safe seal.

Aijiren now offers a full set of GC headspace vial kits, including Screw Cap with Septa. All sample vials are type 1 borosilicate glass, and the range is sufficient to cover all major manufacturers’ instruments, including Shimadzu, Agilent, PE, CTC and Tekmar headspace instruments.

Aijirenen Tech provides you with the widest range of 20 ml headspace gc sample vials, with a gc sample vial magnetic cap, gc sample vial screw cap, and the screw cap of the headspace vial with a center hole for easy piercing of the sample needle The cover pad enters the vial for sample extraction.

The bottom of the headspace vials produced by Aijiren can be flat or round. Can choose according to the model and bottom of the machine. Vials with round bottoms are stronger than flat-bottomed vials and are more resistant to pressure. The round bottom form is designed to make the vial easier to fall into the heating block when being transported by the magnet.

Aijiren’s headspace vials will form a tight seal for accurate analysis and reliable results. Provide threaded transparent or amber type I borosilicate glass. The vial is used to heat the sample until the concentration of the liquid and gas phase reaches equilibrium. Then remove the sample from the gas phase (headspace) for analysis.
