Specimen preparation
Hi everyone,
For the water samples, I find a lot of interesting action is happening attached to solid material but this makes the preparation bumpy and hard to visualize for anything higher than 10x. Any tips?
Thanks

I'm in the same boat you are. I think some folks use long distance objectives.

One trick is to let cover slips float on the sample for a few days, another is to submerge pairs of slides. In both cases the surfaces will become lively after a while and offer interesting observations.

But those objectives have the same depth of field limitations right? So the critters can swim in and out of the plan of focus all the time?Greg Howald wrote: ↑Tue Sep 21, 2021 10:39 amI'm in the same boat you are. I think some folks use long distance objectives.

Re: Specimen preparation
In case you have a plancton aquarium you can simply let the cover slips float, they are carried by the surface tension. When submerging it helps to use pairs as there remains one clean surface.
