The advantages to the glass and epoxy-coated metal construction are twofold: 1. The enclosure does not contribute high electrostatic forces affecting the precision of the balance. 2. The attraction and ultimate accumulation of powders, (hazardous or nuisance), are minimized on the inside of the enclosure. To correct or ensure against electrostatic issues, the following additional measures may be prescribed to improve weighing operations. • Maintain a humidity level between 45 and 60%. The abilit
Prior to using the enclosure, check to make sure that the exhaust blower is operating and that air is entering the enclosure at its specified face velocity. The use of an airflow monitor is recommended to alert the user to a problem with airflow. 2. Use good housekeeping in the enclosure at all times. Clean up spills immediately. Periodically clean enclosure interior. 3. Do not overload the work surface with apparatus or work material. The safe operation of the enclosure is based upon having pro
The filtered enclosures have been tested to effectively contain toxic and noxious materials when properly installed and operated. What makes the filtered enclosures so unique is the revolutionary way they direct air into and through the contaminated air chamber. Labconco engineered the filtered enclosures to minimize the effects of turbulence. The containment-enhancing and aerodynamic designs of the upper sash foil, side air foils, lower air foil, upper dilution air supply, and rear perforated b

See Chapter 6. Saturation Level or Time – There is a limit to the amount of chemical that can be adsorbed by activated carbon, or neutralized by chemically-treated carbon. Once the capacity of the carbon is reached, it is considered to be saturated and will adsorb (or neutralize) no further material; the outlet concentration of the chemical will equal the inlet concentration from that point until the filter is replaced. (Note that the capacity of activated carbon is not a constant, but varies wi
HEPA Carbon Carbon Carbon Important: Carbon filters do not provide any particulate protection, but provide odor control. Connecting the Electrical SupplySource to the Filtered Enclosure 115V Models Simply connect the 115V power cord supplied to the IEC electrical supply plug on the back of the enclosure. If using at 50 Hz operations, blower performance maximum airflow will be reduced by 17%. For the remote blower used for XPert Stations, follow the wiring diagram in Appendix C and wire the blowe

See Figure 4-1 15. Fluorescent Lamp is located above the work area, out of contact with contaminated air. A safety glass window beneath the lamp distributes the light evenly across the work surface. See Figure 4-1. 16. Filter System Pressure Gauge indicates the total system pressure across the HEPA filter and pressurized plenum to help predict HEPA filter loading. See Figure 4-1. 17. Filter Clamping Bolt evenly seals the HEPA filter to the frame of the enclosure. See Figure 4-1 and 4-2. 18. Sash
