Part #11000 Zahm Modified Piercing Device


The Series 11000 Piercing Device is a modified Zahm New Style Air Tester (Series 5000) with the burette (5003-25), burette clamp (5006), support rod (5016), level bottle & stand (5047/5050) & connection tubing (5052) omitted. This instrument is used where a separately mounted burette is preferred for air testing or where a fast, simple closure…

Product Description

Warning: Eye protection must be worn while operating this instrument.

Note: Before using this instrument it should be tested for any gas leaks that may occur at the various connections. This may be accomplished by pressurizing the instrument and applying a soapy water solution to the various connections. A bubble will form if any leaks are occurring. The instrument may also be pressurized, submerged in a glass tank of water, and leaks detected in this manner.


1. Place the bottle or can to be tested on the base pad (5022) and lower the cross bar (5024) to the point where the rubber seal (5045) just touches the top of the container The cross bar is lowed by depressing the lock plates (5026) on each side of the cross bar and pushing downwards.

2. With the lock plates still depressed, push rapidly downward with both hands on the cross bar until the container is pierced.

3. Release the lock plates. The cross bar will remain locked in place with the rubber seal compressed to prevent leaking at the point of piercing. Be careful not to trip the lock plates after piercing as only a slight upward pressure on the lock plates will release the cross bar.

4. Hold the instrument at the bottom of the base with the right hand while the left hand holds the guide rod (5017). Shake the instrument with a rapid back and forth motion until maximum gauge pressure has been obtained. Record this pressure if volumes of CO² gas will be determined.

5. Bleed off the pressure in the container by opening the Whitey valve (5056).

6. Depress the lock plates and raise the cross bar high enough to remove the container.

Determination of Volumes of CO² Gas

Quick disconnect of the PAT unit for carbonyl analysis (achieved by bubbling the carbonyl into a gas washing bottle containing 0.25% 2.4 dinitrophenylhydrazine in 2/n HCl to form carbonyl derivatives, which can be analyzed by HPLC).


Additional Information

Volume Size

1 Liter, 3 Liter

Cleaning of the Instrument:

When the tests have been completed the instrument should be cleaned as follows:

1. Open the Whitey valve and attach a water hose to the nipple of the Whitey valve. Backflush with warm water for several minutes.

2. Remove the pressure gauge from the gauge adapter (5039), rinse in warm water and dry.

Calibration of Pressure Gauge:

The pressure gauge should be tested for accuracy at the beginning of each shift. Procedures for re-calibration are sent with the instrument and are available upon request from Zahm & Nagel Co.
