Amber 9mm HPLC Vials with Insert are universally suitable on most autosamplers, convenient in handling, and available in a broad selection of different cap colors and septum materials.

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 choice of autosampler vials may seem much less important compared to the significance chromatography instruments many laboratories use. However, the wrong choices of HPLC or GC vials, caps, septas and inserts might well lead to lower experiment productivity and reproducibility or even mechanical damage to the autosampler.
