Original instructions
Microscope Installation (optional)
In order to successfully install a user-supplied microscope in a Cell Logic
Biosafety Cabinet with Scope-Ready package, please follow the steps below
and refer to Figure 3-4 as well as Appendix F: Installation Guide for all
Pure-Vu Seals and Stand-Still Isolation Platforms:
Note: The work surface is heavy. Use caution when handling it.
1. Before installing a microscope, locate the Stand-Still Isolation
Platform that is packaged in a separate carton underneath the work
surface. Note: Stereoscopes will typically require the Stand-Still XL
Isolation Platform found at
www.labconco.com .
2. Install the Stand Still Isolation Platform so that the leading edge is in
line with the work surface leading edge. The Stand-Still Isolation
Platform is elevated to promote safe airflow and isolate up to 94% of
vibrations. See Appendix F for typical pictures of proper set-up of the
Stand-Still Isolation Platform.
3. With the sash in the up position, place a user-supplied microscope
inside and on top of the Stand-Still Isolation Platform. Remove the
microscope eyepieces.
4. The Cell Logic Biosafety Cabinet with Scope-Ready Package
includes one Pure-Vu Seal that requires 0.5" (12.7 mm) diameter
holes spaced approximately 2.75" (69.9 mm) apart and located from
the base of the microscope to the centerline of the eyepiece. The
eyepiece holes can be cut with the 0.5" (12.7 mm) diameter hole
Punch Kit (#4027801) supplied with your cabinet.
For your convenience, pre-cut accessory Pure-Vu Seals are available per
www.labconco.com , and may be an easier installation.
5. If punching the 0.5" (12.7 mm) diameter holes, remove the
microscope eyepieces and line up the centerline of the eyepiece base
with the seal. Then mark the centerline of each eyepiece hole spaced
at approximately 2.75" (69.9 mm).
6. Remove the 14 screws (#6-32 x 0.25") that retain the Pure-Vu Seal.
7. Either reinstall one of the pre-cut accessory Pure-Vu Seals from
Appendix D or punch the holes in the blank seal supplied and then re-
install the seal. For your convenience, see Appendix F for installation
of pleated Pure-Vu XL Seals used with stereoscopes requiring
frequent eyepiece height adjustment of +/- 2.0" (51 mm).
8. After the seal is re-installed, then move the microscope forward to
carefully stretch the Pure-Vu Seal over both of the microscope
eyepiece bases.
