Original instructions
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.
Temp-Zone™ Package Option
Models with the Temp-Zone package option include a temperature controlled
area 10.5" (267 mm) wide x 12" (305 mm) deep (7" (178 mm) wide x 12"
(305 mm) deep on 3' models). Samples heated in an incubator or chilled in a
refrigerator may be transferred to the Temp-Zone and kept at optimum
temperature. Quick connection fittings on the left side of the cabinet attach
to a user-supplied circulator that continually delivers heated or chilled water
through channels located underneath the Temp-Zone area of the work surace.
Uniform temperature distribution is maintained on the Temp-Zone area of the
work surface. Temp-Zone work area temperatures of 0.3-0.5°C are
maintained with the circulator heated to 37°C and within 0.3-1.6°C with the
circulator chilled to 3.7°C. Actual set points will vary depending on
variables such as sample tube rack, sample size, and length of tubing.
