Re: How best to clean slides for thin blood smears ??

Hi Garz,
Use a cream cleaner; put a drop on each side of the slide, rub up and down between finger and thumb then leave to dry. When you want to use them wipe the powder off with your lint free cloth.
Hope this helps.

Re: Microtome object holder (Leitz 1212)

Hi iconoclastica,
I would recommend you use a small square block of wood to fit between the clamp jaws. The wax will stick to wood better than metal.
Hope this helps.

Re: Swift 380T - can't focus the whole field of view

Hi Sandra,
It sounds like your objectives are cheep achromats, what you need to have the whole field in focus are "plan" objectives; somewhat more expensive I am afraid.

Re: Anyone else is sick of closing and straining their other eye while looking into the microscope?

Hi smollerthings,
The correct method of viewing with a monocular microscope is to keep both eyes open. Some people draw what they see through the microscope with one eye while viewing their drawing with the other.

Re: I'm very confused about magnification

Hi HiddenWorlds, You are allowing the camera to confuse the issue. When microscopes were first marked with magnification numbers rather than focal length in fractions of an inch it was decided that the magnification would be the number of times bigger the object appeared when viewed at 10 inches.

Re: Unusual Vorticella?

Hi Kwesi,
I once placed a duck weed on a slide, the stem of the weed was covered with vorticella, within minuets of my observing the vorticella had sensed the change in their conditions and abandoned their "stalks" and where "buzzing" around the slide.

Re: How to remove Reichert microtome chuck?

Hi Tom, I would remove the screw near the end of the ram, there may be another screw under the one you can see. Also I would completely loosen all the screws on the collar to see if that makes a difference. Needless to say I have no experience with this breed of microtome so I am only guessing. Peter.
