MTF Member Suggestions
$100-$300 USD
- AmScope M158C-E Compound Monocular Microscope, WF10x and WF25x Eyepieces, 40x-1000x Magnification, Brightfield, LED Illumination, Plain Stage, 110V, Includes 0.3MP Camera and Software. [1] (Note that this microscope will be adequate for counting yeast cells, but not for checking low-level infection, characterizing yeast, etc. [2].)
- 40x-1000x Binocular Biological Microscope. The objectives have the minimum NA that Bryan recommends. It also has a mechanical stage which (Mark Trent) recommends for counting (makes it much easier to move from one square to the next). But make no mistake, it is not a research grade microscope. It does work fine for counting yeast and you can make out the shape of bacteria using the 100X objective with oil, which takes a little practice [3]. The example image is Sacch cells under the 40x-1000x Binocular Biological Microscope. Cells appears clearer than the images when viewed directly. Images by Mark Trent:
Larger Sacch cells
Smaller Brett cells
$1,000-$4,000 USD
These microscopes are recommended for commercial brewery labs.
