Spot bottle 0.40 l. FFKM
1. Install the HERMetic Sampler GTX Chem with the sampling bottle on top of the HERMetic 2” ball valve
by means of the quick connect coupling.
In case the air which is inside the HERMetic Sampler housing can contaminate the sample it is
recommended to purge the Sampler after it has been installed on the HERMetic 2” ball valve but
before
opening it.
1.1. Check that the HERMetic 2” ball valve is closed.
1.2. Open the transfer valve.
1.3. Install an inert gas bottle to the pump connector. The inert gas pressure shall not exceed 0.3 bar.
1.4. Apply the inert gas through the pump connector to purge the HERMetic Sampler.
1.5. After purging close the transfer valve.
2. Prepare the hose connection from the transfer valve to the laboratory bottle. Check that its capacity is at
least 0.5 l.
3. Open the HERMetic 2” ball valve.
4. Lower the spot bottle to the level where the sample is to be taken.
5.
Stop the bottle at this level and shake it rapidly up and down about 10 times on a 100 mm stroke. This
movement has a pumping effect as the bottom ball of the container opens and closes quickly.
6.
Lift the bottle back into the HERMetic Sampler housing; turn the crank until getting a catch that keeps
the tape fully tight.
7. Close the HERMetic 2” ball valve.
8. Lower the sampling bottle until sitting on the ball of the HERMetic 2” ball valve. This will open the valve
of the sampling bottle.
9. Open the transfer valve.
10. Install the pump to the pump connector. If the liquid is air oxygenating install the inert gas bottle set up at
0.3 bar maximum.
11. With the pump (or with the inert gas) transfer the liquid from the sampling bottle to the laboratory bottle.
12. When the transfer is completed, close the transfer valve.
13. Remove the pump or the inert gas bottle.
14. Lift the sampling bottle and lock the crank.
15. Open the HERMetic 2” ball valve
no more than 30°
to drain any residual liquid back into the tank.
16. After draining close the HERMetic 2” ball valve.
17. Remove the HERMetic Sampler GTX Chem from the HERMetic 2” ball valve.
