Our KYNAR® PVDF gassampling bags come with renovated, patented valves. Valve materials are polycarbonate and PTFE. Unlike other popular valves, our valve does not have O-ring inside to prevent leakage so contamination is minimized.

Features:

* excellent chemical resistance

* strong physical property

* superb strength and low permeability

Connectors


Side-opening stopcock valve

It has similar functions to the stopcock valve . The difference is the connector it

horizontal to the surface of bag. The sampling cap is opposite to the connector.

This patented design is convenient for filling and sampling gas.


PTFE straight valve

It is made of polytetrafluoroethylene (PTFE). The patented design utilizes

mouldeling, self-sealing mechanism, no O-ring is inside therefore

cross-contamination is eliminated. The PTFE valve can handle gases that there

is not corrosive to PTFE. The valve can be used in VOCs analysis.

PTFE straight valve plus fitting

It is made of polytetrafluoroethylene (PTFE). The patented

design utilizes mouldeling, self-sealing mechanism, no O-ring is inside therefore

cross-contamination is eliminated. The PTFE valve can handle gases that there

is not corrosive to PTFE. The valve can be used in VOCs analysis.

Stopcock straight valve

It’s made of medical grade polycarbonate (PC) with 6mm connector. Valve stem

(connector) is vertical to the surface of film. The valve utilizes patented technology. The

valve body and cock are modeled and polished so that the valve does not need lubricant

and sealing part, the cross-contamination is eliminated.The valve not only has on/off

function but also can control flow rate. When turn handle toward the connector, the valve is open. The valve is closed when the handle is turned vertically to the connector. The crewed connector has cap with silicone septum in it, which is convenient for sampling. Since the valve does not introduce any potential contamination, it can be used for VOC analysis.

Operating instructions for PVDF bag

1.Avoid filling pressure higher than 6000Pa. Fill gas until the bag is fully expanded, however, it is not so tense when you press it using your finger.

2.Keep away from flame and high temperature when filling and storage. Avoid contacting sharp stuff.

3.Before use, flush sampling bags three times with the gas you want to fill.

4.When using a needle to draw gas from highly elastic septum, squeeze the septum with fingers in order to restore the sealing property after pulling out the needle.

5.Heat-resisitance temperatures should be 150°C to 170°C . Operating instructions for PVDF bag
