Performance Features
The Precise HEPA-Filtered Glove Box is designed to meet the needs of the
laboratory scientist, and provide superior particulate containment. The
HEPA-filtered glove boxes have been tested to effectively contain toxic and
noxious materials when properly installed and operated. Labconco
engineered the HEPA-Filtered glove boxes to minimize the effects of
turbulence. The concentrations of particulate materials are predominantly
removed from the main chamber by controlling the frequency of main
chamber air volume changes. See Figure 4-1 to refer to a detailed description
of the main performance features.
1. Molded One-Piece Chemical-Resistant Glove Box Shell made of
medium density polyethylene, which provides superior chemical
resistance. The molded liner is seamless and easy to clean with coved
interior corners.
2. Versatile Vibration Isolated Motorized Impeller Isolation supports
eliminate the transfer of vibration to the work surface which is extremely
important in weighing operations with precision analytical and micro
balances. The impeller wheel is also dynamically balanced capable of a
minimum airflow of 13 CFM to a maximum of 100 CFM. Measured
displacement for vibration is less than 1.5 x 10
-5
inches. Additional
unique features of the impeller include an optional Positive Pressure Kit,
a Recirculation Kit, and a Blower Wall Mount Kit (see Chapter 7).
3. HEPA Filter System consists of the inlet and outlet HEPA filters rated
99.99% efficient on 0.3 micron particulates. Inlet and outlet HEPA filters
are identical and include a test port for challenging the HEPA filter
integrity. An optional filter bag may be ordered for bag-in/bag-out filter
change procedures (see Chapter 7).
