Original instructions
Note: UV irradiation is absorbed by the tempered safety glass of the sash.
Independent research has shown that the level of UV irradiation on the
outside of the cabinet’s sash is equal to background radiation levels.
Note: The UV sensitivity of a target organism varies, depending on the UV
output of the lamp, the genus and species of the organism, the medium the
agent is suspended in, etc. Contact the Health and Safety Officer at your
facility for UV light use and recommendations.
Scope-Ready™ Package Option
Models with the Scope-Ready package option allow a user-supplied
microscope to be integrated into the safety cabinet. On these models, two
features work together to assure containment and reduced vibration:
• The Pure-Vu™ Seal includes a 7" wide x 10.5" (267 mm) high sash
cutout that accommodates most microscopes’ eyepieces. The clear
disposable eyepiece seal prevents contaminants from escaping while
providing ergonomic visibility into the cabinet. The easy removable
seal attaches tightly to an aerodynamic, epoxy-coated steel collar.
The unique teardrop shape of the aerodynamic collar design keeps
contaminants contained with the microscope in place. The Pure-Vu
Seal conforms to both ASHRAE 110 and NSF 49 testing criteria.
• The Stand-Still™ Isolation Platform supports the microscope on the
cabinet’s work surface and removes up to 94% of vertical and
horizontal vibrations. ASHRAE 110 and NSF 49 testing confirms
this unique elevated, aerodynamic base ensures safe airflow.
Constructed of seamless Type 304 stainless steel, the isolation
platform is non-porous, easy to clean, and autoclavable. Important
Note: Always remove the rubber isolation feet prior to autoclaving.
The spacious 12" (305 mm) wide x 18.75 (476 mm) deep platform fits
most microscopes. See Appendix D: Accessories for ordering an
extended Stand-Still XL Isolation Platform for use with microscope
bases that extend over the front of the lower work surface.
