Re: An unknown chinese microscope for a newbie

That looks like a really nice microscope. Just remember that even though it's from China, it's far from junk. China is known for superior, top quality optical equipment.

Re: Oops! With a 40x objective.

What I do if I'm going to use oil is to lower the stage, turn the objectives to the 4x, add oil, then turn to the 100x. That way I know I'm safe with my objectives.

Re: Omano OM159 condenser?

Is that an old microscope ? if not, and if the only way of knowing whether it can move up and down is to buy one and try, that says something about the post-purchase support and customer service... and documentation of the microscope... It's a new model and I bought one and it does go up and down. ...

Re: My first microscope thank you for your help that you did not even know you had given.

You have a real nice microscope. I also have an Omax, and I really like it. If you can answer these three questions with a yes, then you did good. 1. Did you get a good deal on the purchase? 2. Are you happy with the microscope? 3. Does it meet or exceed your expectations? I own several microscopes ...

Re: A source for diatoms

Diatoms can be found in different places so why not start with something simple. When you scrape of the slime film on water plants you will usually find diatoms, and not too much dirt. Then you place some diatom slime on a cover slip, place the cover slip on a piece of flat stainless steel sheet me...

Re: A source for diatoms

Hi Steve, whether you will find complete diatom frustures or not varies from product to product. As this is no defined property of the product it may vary too. Generally you have to expect lots of broken bits and an intact diatom here and there. Especially the bigger diatoms will be broken most of ...

Cool. I have a similar stereo. One thing I can say is, make sure the base and scope are very heartily locked. If the base is not connected with a strong lock, the scope will move around for well over a second when changing the focus, before 'settling'. If you take a picture during this time, it wil...
