Re: immersion oil in canada (bonus for calgary)

Almost all unit or small shipments to Canada are treated as " foreign" and despite the relative ease to ship here, the cost usually goes stratospheric. There is a lot of gouging. Ebay is a reasonable choice but irregardless, it's going to be 2 weeks at a minimum. Immersion oil is available around th...

Re: Stereo Microscope for a Beginner

Welcome to the forum. To add to the good advice above, a word of caution. Entry level microscope marketers, which includes probably all of the companies that infest the googled pages , always overstate magnification potential. Einman, mentioned this in another way, referring to empty magnification. ...

If you know a vet clinic well enough, they might let you buy one from them. They can get it easily from one of their veterinary suppliers and also usually have an extra 1 or 2 on hand. Some farm supply stores can get it or carry it because some farms do egg flushes for selective breeding....mostly c...

Re: Micro Shrimp

This is not truly a shrimp, which for instance have stalked eyes, but is from another line of crustaceans called amphipods. I think the spines on the abdomen and lack of any apparent branch on the antennae mark it out as a Hyalella , at least among North American genera; I don't really know if othe...

Re: Selecting the correct Darkfield stop

Ii is hard to tell, without seeing the actual optical view but I would say # 1 has the best combination of contrast and resolution. Higher power phase rings also make great low power df stops. On AO the 100X phase ring works great with the 4X objective when using standard 1.0mm slides or thereabouts...

new adapters for AO and AO/Reichert

I had Rafi make up some adapters for AO a while ago. He is very fast with the design and tooling but has to send out for the anodizing. They are finally ready. One of the aspects of the AO dovetail is that it is in imperial measure....2 inch, so the closest common match 49mm is a bit skewed. Rafi's ...

I can't see that not being an excellent microtome. It probably can be used as is but it had a conveyor belt attachment originally, that the little rotating drum activated. It is an OM-S, I think, unless they made a simpler model, without the conveyor belt. The little black knob and small hole toward...

They didn't really have infinity lenses until they started marking them but in the series 4, which directly predated the infinity series, you can use the later infinity lenses and they are actually better than the previous series.

All AO microscopes with planachro optics are infinity corrected. Somewhere on the barrel, there is an infinity symbol.
