Maintenance and Care
The ZHE+ zero headspace extractor should be thoroughly cleaned and inspected
before each use. A non-abrasive laboratory cleanser such as Alconox® or Sparkleen®
is suitable. Do not use steel wool or abrasives such as Comet®. It should be rinsed
with laboratory-grade water. All O-rings should be inspected for signs of wear before
each use, and frequent replacement of O-rings (Item # ZVR1000), along with the rings
within the plug valve (Item # ZVR9903), is recommended to reduce both sample and
blank contamination.
Note:
316 grade stainless steel is a hard, inert metal, but possible to damage.
Avoid rough handling and overexposure to corrosives.
Periodically a leak test on the ZHE+ unit should be performed to ensure proper
operation. To perform a leak test, fully assemble the unit and pressurize to 50 psi.
Leave pressurized for an hour and check the gauge for any pressure loss. If a
pressure loss is found, re-pressurize the unit, place under water and look for bubbles.
It may be necessary to replace O-rings or tighten fittings.
