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.

Micro vials are designed to assist in the consistent sampling of low-volume chromatography samples.

Polypropylene vials are an economical alternative to glass for some applications. The vial is primarily constructed from high-quality, durable polypropylene or polymethyl pentene (PMP). This plastic is typically chosen for its chemical resistance, inertness, and transparency. 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, increasing the sample’s visibility inside the sample bottle. The vial typically has a standard 9mm outer diameter, making it compatible with a wide range of autosampler systems commonly used in laboratories.

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allows for easier needle penetration as well as to release of the vacuum that forms when a large volume of sample is withdrawn from a vial.
