Samples with a lower volume than 1.0 mL have to be delivered to the autosampler in appropriate micro vials, in order to offer the needle ideal conditions for sample removal. During selection of the most suitable product, safety, handling and price are important factors.

Originally headspace analysis was only carried out with crimp neck vials due to the temperature reistance of the caps (aluminum with an appropriate septa type) and the gas tightness being expected by endusers to be the highest. However, with the success story of the CTC Combi PAL and identically constructed autosamplers that require magnetic caps for transportation, consumables startet to change.

Are you looking for high quality consumables for Waters® autosamplers, like the Alliance® or the ACQUITY™ UPLC Systems?
Please check this flyer for suitable vials and caps that also include bonded screw closures N 9 or vials with integrated inserts. Appropriate cross references to the Waters® products can be found at the end of the flyer; an overview on autosampler compatibility is listed directly in the beginning.
