With the strong will of tracing the trends of updating technology
and meeting the customers’ requirements, as a new-coming youngster,
ZHICHENG widely adopts suggestions and earnestly consults the
advanced technology of competitors, based on which, ZHICHENG has
developed ZSA-2 intelligent biological safety cabinet with
pertinent technique and capability improvement, and effectively
supplied a gap of present biosafety cabinet. That is an
internationally leading model, strongly armed with five biological
safety protection shields.
Biological safety cabinet, the biological safety protective
equipment for lab experiment, secure the operating staff and
environment by prevent the noxious suspended particle from
diffusing during the experiment. With the development of high
technology, the improvements on the safety of operating staff,
environment and samples have been approved in the recent years.
While in terms of the stricter requirement of security sense, some
of the problems, like the low velocity, low negative pressure and
biosafety cautions under some abnormal conditions have not been
perfectly solved.
ZSA-2 Intelligent Biological Safety Cabinet is class Ⅱ, type A2,
which adopts omnidirectional, wide visual angle, multiparameter and
solid safety technology and constructed five biological safety
protection shields, and significantly promoted the guard of the
biological safety of operating staffs and samples.

1.The constant velocity technology can avoid the risk of leaking
because of low velocity or low negative pressure that caused by the
voltage fluctuation or increment of HEPA (ULPA) resistance.
2.The collection efficiency of ULPA for the particle , smog,
microorganism between 0.1~0.2m exceeds 99.999%
3.The blower’s full pressure is as 2 times as the initial pressure
of HEPA, which effectively extends HEPA service life and reducing
the operating cost.
4.With the omnidistance monitoring technology, the LCD fully
displays various real parameters, such as velocity, differential
pressure, air quantity and HEPA (ULPA) running status, etc.
5.With the innovative internal negative pressure design, any
leaking airflow will be captured and environed by the negative
pressure system.
6.ZHICHENG unique airproof design, epoxy resin coat on stainless
steel frame and airproof door cover ensure no air leaking under any
circumstances.
7.Self-testing on ULPA/HEPA running status
8.ULPA/HEPA invalidity pre-warning and alarming system
9.ULPA/HEPA breakage alarming system
10.Double alarming system, linked with internal blower fan,
consists of independent low velocity alarm and main circuit
11.Sash over-lift audio and visual alarm
12.Self-diagnosing system provides instant reaction for supply and
exhaust air fan malfunction.
13.Preset disinfection enhances work efficiency.
14.Linkage design between sash and UV lamp protect operator from
accidental ultraviolet radiation.
15.In terms of human engineering, the transparent sash design with
incline angle of 10°reduces the glare to maximum extent, which
makes the user’s operation more convenient.
16.Non-reflecting double tectorial glass specializes in explosion
protection, breakage proofing and ultraviolet proofing.
17.Particular seamless sealed inner surface and one piece formed,
detachable stainless steel operating platform are solid, perdurable
and easy for cleaning.
18.Waterproof outlet and standard water and air valve fittings
19.Fluorescent lamp, installed out of the work area, makes it easy
to fix and free of pollution. Illumination intensity is higher than
that the NSF standard Section 49 indicates.
20.The contaminated air can be exhausted into the room or out
through ducts.
21.ZHICHENG provides all duct fittings. |
