The MiniCapt® Compressed Gas kit enables the MiniCapt Mobile Microbial Sampler to conduct microbiological monitoring of compressed gases. The compressed gas kit is intended for use with the 25 LPM, 50 LPM, or 100 LPM MiniCapt Mobile.
This compressed gas kit employs a specific diffusion chamber that is directly affixed to the MiniCapt inlet, the other end of which is directly linked to the high-pressure gas distribution line.
A pressure regulator is installed in the sample line (between the high-pressure gas source and the kit’s intake) for safety and to control the flow rate of the gas into the diffusion chamber.
A solenoid valve is connected downstream of the regulator and enables the MiniCapt to synchronize the gas flow with the start of a sample.
The principle of the critical orifice is used to regulate the flow of the gas that has to be sampled. The crucial orifice controls the flow rate into the diffusion chamber and the exhaust under operational pressures.
Benefits
- Compact size for convenient access to sampling points
- Inexpensive monitoring of pressurized gas with atmospheric pressure
- An accessory to a previously validated instrument
- Does not require further qualifications
- Comparatively lightweight in comparison with competitive instruments
- HEPA air filter for overpressured air and inversion from low pressure/flow prevents contamination
Features
- Measures gases of 0.5 to 10 bar (7.2-145 psi) using the model-dependent range
- Suitable for use with argon, nitrogen, carbon dioxide, clean dry air (CDA), and other non-toxic inert gases
- No external flow meters needed
- Three different versions: 25, 50, and 100 LPM flow rates
- No moving parts to wear
- Autoclavable stainless steel construction (removable solenoid valve)
- Ease of cleaning with isopropyl alcohol 70/30, sodium hypochlorite 1 %, and hydrogen peroxide (up to 6 %)
Applications
- MiniCapt Mobile (25, 50, 100 LPM)
