6100CR Refrigerated Sampler - Isco

6100CR Refrigerated Sampler
Section 3 Installation of the Sampler
11. Reinsert the valve stem into the valve body by pressing
and twisting the valve stem into the valve body at the
same time. Turn the valve stems so their final position is
perpendicular (90°) to the bottle.
12. Reassemble the bottle rack with the cleaned bottles. Make
sure all valves are closed. It is very important to keep the
valve stems closed to prevent contamination.
CAUTION
The bottles used in the 6100CR are borosilicate (hard) glass,
also known by the trade name of Pyrex ® . Their capacity is 40
ml. Teledyne Isco does not recommend the use of bottles other
than those supplied by Isco to ensure conformity with the original
equipment dimensions. If you use bottles from a source
other than Isco, the bottles must have identical length, diameter,
and cap thread as those supplied with the sampler. For
safety reasons they should also be made of hard glass. Failure
to use identical bottles may result in crushed bottles or a damaged
needle assembly, and will result in an inoperable sampler.
3.5 The Booster Pump Teledyne Isco offers a booster pump accessory for 6100CR samplers
when the pressure from the incoming sample lines is found
to be inadequate to properly supply the sampler. Minimum
sample line incoming pressure must be at least 20 psig. The
booster pump raises the pressure of the incoming line to 35 psig
if it is below the 20 psig minimum. This is enough pressure to
allow accurate calibration of the sampler at 2 ml/sec.
The booster pump consists of a housing, controls, and a
motor-driven gear pump. To maintain the integrity of the
incoming sample fluid, the pump gears are made of Teflon. The
housing containing the booster pump is mounted on the side of
the 6100CR (see Figure 3-8). The interior of the booster pump
housing is shown in the Figure 3-9.
Note
The pump must never be run without liquid inside the lines.
Operation of the pump without liquid will destroy the Teflon
gears inside the pump head.
