All-in-one closure for TOC/VOC analysis
High recovery vials are - from the outside design - standard vials, however, with a solid glass bottom with an inner cone in it. This way they offer a very low residual volume with a high total volume at the same time. In addition they don’t need any adapters to run in an autosampler, as require micro-vials with a conical bottom.
High recovery vials are ideal sample containers for reactions or concentrations, as the solid glass bottom offers excellent heat transfer. In unconcentrated condition the sample has a fairly high volume requiring standard sample volume vials. After the concentration process the needle necessitates optimal conditions for sample removal of the now only small amount of sample. The inner cone in the bottom is ideal for this, as the sample always will flow to the deepest point in the bottom. This way concentration processes do not require sample transfers from large volume vials into smaller micro-vials that may cause sample loss.
- All-in-one closure for sample collection/transportation/storage as well as for TOC/VOC analysis
- Ultra-pure Silicone/PTFE septum, which is protected by the removable protection lid against any contamination in the lab
- Safe penetration due to the soft Silicone/PTFE septum, that is firmly connected to the screw cap (bonded screw closure)
