Chromacol's Micro+ vials have a low volume insert permanently fused into the external holder to give a standard 12mm x 32mm external dimension.
This makes the vials compatible with the widest range of autosamplers and sample handling systems without having to change racks or injectors. As the needle extracts at a fixed depth, it extracts from a fixed insert that collects the residual liquid sample.
The taper on such vials also forms a reservoir and the volume of only a few tens of microlitres is enough to allow a standard needle position to be used. The Micro+ range of Chromacol vials give almost complete recovery of liquid sample from the reservoir.
For larger sample volumes the Micro+ vials, including the 03-FIV and 09-FIV, give over 99.5% recovery even when not set at optimal needle depth.
For pre-concentration of dilute samples the 09-Fused Insert vials may be used depending on the original sample volume.
