Limited Volume Vial Inserts

How to select the proper insert

Solvent Compatibility:

Glass is most commonly used for vial inserts. Polypropylene or polyethylene may be necessary when using pH sensitive samples.

Targeted Residual Volume:

Mandrel point inserts provide the smallest residual volume so are suitable when minimizing sample loss is important. Conical bottom inserts provide sufficient sample extraction for most applications.

Price:

Flat bottom inserts are the cheapest and may be a viable option for limited sampling. Mandrel point vial inserts are the most expensive but they minimize sample loss and provide excellent injection accuracy.
