Patented System Gives High Reproducibility in Autosampler Instruments.

This patented system gives the chromatography user the ability to inject reproducibly from glass vials with total volumes down to 100µL in a full range of autosampler instruments. In combination with precision sleeves it allows manipulation of sample volume down to the nanoliter level in conventional autosampler units.

The clear vials are manufactured from Chromacol GOLDâ„¢ glass, a low expansion high purity glass with an extremely low concentration of active sites. This gives a low activity surface with high recovery of basic and polar samples that may show adsorption on more typical glass surfaces.

There are three volumes of vial available within the SCI-VI system. All have a 8mm crimp top closure, which is compatible with a wide range of standard aluminium crimp caps and liners.

The lowest volume commercially available glass vial is the 100µL 01-CVG. This has a smaller inner diameter than the other vials in the series but has a precision conical lead-in that directs the autosampler needle into the low volume reservoir. With a total volume of only 100µL this is a true microsampling product, with applications where sample volumes are limited by cost or availability

02-CTVG With a useable volume of 200µL and with a precision conical taper this vial is also available in amber glass as the 02-CTV(A). The conical taper gives a residual volume of less than 1µL. This may be used in place of conventional inserts where the sample integrity needs to be retained within the single vial.

03-CVG With a useable volume of 300µL and a residual volume of less than 2µL the round base allows sample concentration within the vial.
