Chips & Cracks in the Jar

Tip 28: Make inquiries about chips or cracks in the #duisimulator jar. Use FOI, Stinchcombe, O'Connor, or cross-examine to make inquiries about chips in the glass edge of the simulator jar. Henry's Law cannot apply to a simulator / alcohol standard system that is not sealed and at equilibrium.

Over-tightening the wet-bath simulator jar or a worn o-ring between the jar and the housing can cause chips in the edge. A simulator jar screwed tightly to establish a seal when there are already problems with the edge can cause a crack in the jar causing further difficulty with opening.

Guth supplies police with a silicone lubricant whenever police purchase a new simulator. It appears that police rarely use the lubricant between the jar and the housing.

It is the responsibility of the qualified technician to check the simulator jar whenever the alcohol standard is changed. See CFS 2013 8000C Training Aid page 87 of 238:
