Grasshopper3 with ToupView (not working)
Hi, I frequently use ToupView with MU cameras without problems. I'm trying to control a Grasshopper 3 from ToupView and I can't. From FLIR, they have provided me with the necessary drivers to use the camera in third-party software. I use Windows 7 64-bit. I have seen that in the old versions of the ...

Re: Slide mounting media for a beginner - observations
AFAIK the solvents for Numount are toluene or xylene - both much more hazardous than alcohols. In the end, it all depends on the quantities in use and aeration of the workspace. If you have access to a fume hood, then no problem with any mountant. About Karo etc: which sugar crystals are to be moun...

Re: Slide mounting media for a beginner - observations
The shellac is applied to the cover slip and fully dried. This allows to move the objects on the shellac layer. The bonding takes place by softening the dried shellac layer with heat. So the sugar crystals only have contact to shellac, not to ethanol. In diatom arranging a thin layer of skin fat is...

Re: Slide mounting media for a beginner - observations
Indeed, sugars dissolve to some extent in alcohols (and other polar solvents), so mounting sugar crystal within a thick layer of alcohol-based mountant seems unlikely to succeed. Perhaps if the shellac layer is so thin that only a small surface area of the crystal touches it, mounting will work, bu...

Re: Slide mounting media for a beginner - observations
Hi, in dry mounts you might fix the crystals to the slide with shellac. A very thinly mixed shellac in water free ethanol leaves a thin clear shellac layer on the cover slip. By heating the mount to 60°C you can soften the shellac so the crystals would stay in their pattern. A different approach wo...

Re: Slide mounting media for a beginner - observations
Hi, Interesting thread. For a school project with sugar and steromicroscope, I need a mounting medium with the following characteristics: - Permanent - Not toxic - Colorless : very transparent. - Inert : which does not destroy or alter the composition or color of sugar. - Slow or semi-slow drying : ...
