My cleaning solution changes depending on the nature of the filth... First pass (if I don't know if the dirt/stain is polar or nonpolar or a mix of several components) is usually Edmund Optics cleaner. This is a mixture of Butyl Cellosolve and 2-Propanol, which is a good intermediate polar solvent m...

Spring Phacus

Spring is finally arriving in the Oregon Coast Range. Trillium are out, and my Phacus culture is starting to grow out as well. I also finally got some spare time and modified all my scopes to use 50W LED arrays in place of the 100W halogen lamps they had previously been running. This is my first set...

Truly wonderful DIC image. Where did you get the appropriate lower prism for a 1.4 NA / 1.4 NA double immersed system?
Great shot. Well worth what I know from experience is a messy post-imaging cleanup....

Hey I am still here, and even post every so often when I can take the time from my day job looking at stuff under various electron microscopes to take some time looking at stuff under the optical scopes at home... I am most sorry that I didn't post drawings for this particular adapter. However, as t...

I was just about to add that I have some Edmund IR blocking (absorptive) glass in front of the halogen lamp now. I will look up the part number. My orthoplan halogen LH has this already. I am planning on replacing the halogen lamp with an LED in the future, so I won't be able to just fire the flash ...

On my BX-60, which has a very similar if not identical lower illumination path to your BX50, I just milled out a slot in the back of the LH100-3 lamphouse for a Nikon SB-80 or similar flash and shot it straight through the lamp. A real kohler system won't be too perturbed by the small distance chang...

Hi Mike, One thing you may want to invest in is a small crock pot and a simple proportional temperature controller. You can find used YSI models on ebay. That makes a really nice paraffin oven, and avoids the problem of getting water into your paraffin. Also, a gallon of Histoclear2 is a much better...

Ahahaha. The spider is true NW denizen now, look at his dilated pupils...he's been visiting our newly legalized "cafes". Charlie didn't have to do anything to immobilize the spider under the scope...he just put some Tangerine Dream on the stereo and the spider just sat there under the scope grooving...

Great shots. I especially like number 3 though. I've always wondered how toxic the hydra's venom is towards a cladoceran or similar prey. Clearly its not a "one hit" kill since this one has survived at least 2 shots...

David

p.s. where did you find the hydra?

They're all great, but 3 and 4 are my favorites due to the varied autofluorescence colors. Great shots. What ex/em wavelengths did you use?

Thanks to all. Mike, this accidental culture was so thick that in a small culture flask you almost could not see through it. Unfortunately I forgot to take a picture of the hoof prints themselves. I am culturing the Euglena now, but it will take at least a few weeks before the cultures to grow to su...

That makes me appreciate the bubbles in my slides from a whole new perspective. Are these air bubbles in water or in a different medium?
