From one of my Architects:
**quote:**We are looking for a curtain/ darkening shade to be used in a BSL level 2 laboratory. The shade will be mounted to a track on the ceiling in order to darken a small area around a fluorescent microscope. The area doesn’t need to be entirely blacked-out, but dark enough to enable users to use the microscope. Our client would like a product that resists bacterial growth, doesn’t collect dust, nor promote dust, and can be wiped down with a cleaning solution that will be a diluted mix of ethanol and water.
Any ideas?
