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.

The 1.5mL 9mm Short Thread Vial ND9,with its 9mm short thread design and capacity of 1.5-2.0mL, this vial makes for easy handling and integration into autosamplers. Ideal for applications requiring limited quantities. The vial comes equipped with various finishes and closure options, such as screw caps and snap caps, so researchers can select their ideal choice according to their unique research needs.

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allows for easier needle penetration as well as to release of the vacuum that forms when a large volume of sample is withdrawn from a vial.

China High Quality 9mm Short Thread Caps with Septa for 10-425 thread vial Manufacturer

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.

Aijiren clear glass vial inserts, polypropylene vial inserts, and high recovery vials ensure you extract the maximum possible amount of your precious sample.

9mm PP Screw Top Vial can be made of polypropylene or polymethyl pentene (PMP). Polypropylene is the most popular plastic material. Polypropylene vials have heat resistance of up to 135 degrees Celsius and are commonly used in chromatographic experiments.PMP has higher heat resistance – up to 175 degrees Celsius – and is transparent, which increases the visibility of the sample inside the sample bottle. Plastic vials have good chemical resistance, lightweight construction, durability, and economy.

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.
