Standard Design
| Standard Design | TYPE A | TYPE B |
|---|---|---|
| application | for high-toxic liquid media | for less toxic resp. polluted media |
| bottle connection | needle system and bottle protection | PTFE-adaptor |
| sample bottles | clear glass or SCHOTT-DURAN labaratory bottle with ISO-thread | clear glass or SCHOTT-DURAN labaratory bottle with ISO-thread |
| bottle volume(VF) | 60, 100, 250, 500 ml | 60, 100, 250, 500 ml |
| standard diaphragm (Septum) | rubber/ PTFE | – |
| temperature (Tmax) | 230°C | 230°C |
| Needle diameter | 2, 4, 6 mm | 6, 8, 10, 15 mm |
Bottle connection
- PTFE-Adapter: for laboratory bottle with ISO-thread GL 32/45. Application: For less toxic resp. polluted media.
- Clamping Retainer: For fast and easy exchange of laboratory bottle, even for heated version.
- Needle system: closed needle system for laboratory bottle with septum (Butyl and PTFE). Needle System NH and NH-S with diverse internal diameter(2-6 mm). Application for high toxic resp. polluted media for spillnig eliminated an contamination free sampling.

Operating temperatures < -30°C and > 220 °C have to be checked and approved by AZ according to the operating conditions.
Besides the P/T value of the sleeve the limitations of the valve bodies also have to be considered. Please refer to the EN 12516-1 resp. ASME B16.34 in order to choose a proper pressure rating (PN/class). The shown values refer to austenitic stainless steel 1.4408 (A351 Gr. CF8M).
1) For operating temperatures below -10°C low temperature / austenitic steels are required.
2) Sleeve: There are different sleeve materials / compounds available.
