For TOC/VOC analysis it is important that vial and cap are kept clean during the whole process from sample collection to final analysis, in order to secure reliable results. A weak point in the system might be the cap’s center hole, as the septa surface lies openly and thus is exposed to possible contaminations from its surroundings. To prevent any unwanted condensations / depositions of irrelevant substances onto the septa’s surface, MN REF 702168 has a removable protection lid. It assures samples collected and septum are unaffected by environmental conditions during transportation back to the lab. There is no need for usage of multiple caps (one for sample collection, transport and storage and another one for analysis), as the cap design is an all-in-one open and closed top cap by the removable protection lid.
The fully interlocking cap cover design stays in place until it needs to be removed for analysis. The sealing septum consists of high purity Silicone/PTFE being bonded to the cap ensuring safe penetration with a needle. It has been pre-conditioned to meet EPA standards.
The cap can be used on our 20 mL, 30 mL, 40 mL and 60 mL EPA screw neck vials being available in clear and amber glass. The closure can be bought as a single component or with a vial of your choice as a pre-sealed vial-closure combination.
All-in-one closure for TOC/VOC analysis
- 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)
