Beschreibung

General description

These valves are very easy to use.
1. Push the green button to open the valve
2. Insert the needle through the septum and take sample
3. Remove the needle and push to close
Benefits include:

• PTFE construction for inertness. PTFE is useful when working when acids and organic solvents.
• Good sealing ability for containing most volalite liquids and gases at low pressures
• Mininert valves can be used at temperatures up to 105 °F.
• 0.036 in. (0.9 mm) opening accepts up to 20-gauge needle

Silicone septa, red

Application

Mininert^® valve may be used to seal screw-thread side-arm holding Erlenmeyer flasks containing enrichment cultures; during enrichment culture technique which was used to isolate bacteria from activated sludge, capable of degrading a wide range of aromatic hydrocarbons in mixtures, like ethylbenzene (EBZ), o-, m-, and p-xylene, naphthalene, isopropylbenzene (IPB), styrene (STYR), 1,2,4- and 1,3,5-trimethylbenzene (TMB), 2-chlorotoluene, and 1,2-, 1,3-, and 1,4-dichlorobenzene (DCB), as sources of carbon and energy.

Mininert valves are leak-tight closures for vials and other containers. They are available in both crimp and screw thread versions. Only PTFE and glass are in contact with the contents of the container. They are the ideal closure for the following applications:

• calibration standards
• air- or moisture-sensitive fluids
• derivatizating reagents
• volatile chemicals

Other Notes

The maximum temperature that Mininert Valves can be used at is 105° F. When Mininert Valves are used at high temperatures, returning them to room temperature may cause the valve to leak slightly.
