Hi Oxalis80,
I don't know why borax is included in this formula, however, it is often used as an antibacterial agent.
Borax should be easily obtained at a bulk laundry supplier.
Hope this helps.

Hi Txiki,
I would suggest you ask Bresser on their web sight.

Hi Btschumy,
A good DIC microscope would catapult your photos to near the top of the heap.
Peter.

Hi Kalleboy, I will try to answer your questions, others may answer better and/or more fully. - Is it possible to turn like a basic Zeiss microscope to an electron microscope ? No, a light microscope uses "glass" lenses were as an electron microscope uses electromagnetic lenses. - What parts do I ne...

Hi Dnielaflors,
You do not state what kind of filter you are after, however, if you want a variable colour filter crushed clear glass in a mixture of benzene and alcohol can achieve this by adjusting the proportion of benzene to alcohol.
Hope this helps.

Hi Catherine,
It has been my observation that excrement in damp conditions often grows mold.

Hi cpsTN,
This page http://zeiss-campus.magnet.fsu.edu/arti ... ution.html will explain it much better than I can.
Hope this helps.

Hi Johann,
I think this is a mite. A few mites ar aquatic.

Hi ahpuchplayer, You could do worse than http://www.ebay.com/itm/Bausch-lomb-Microscope-Objective-set/361841001061?_trksid=p2047675.c100011.m1850&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D38530%26meid%3D1f0950882fb94d05bcd5a431d73b86af%26pid%3D100011%26rk%3D5%26rkt%3D12%26sd%3D3618391...

Autumn defoliation, perhaps?

Hi 75RR,
I have/use a product called De-Solv-it (probably unavailable where you are). The claims are it is "organic" and based on natural citrus oil. What ever; it usually works for me.
Peter.

My best guess is sponge spicule.
Peter.

Hi MicroInspector,
The object in your second photo is the shell from a ostracod. The first animal in your vidiomicrograph may be an insect lava, the second animal is an aquatic flatworm.
Hope this helps.

To me it looks like a bubble has been trapped between the wing and the cover slip, The mottle is condensation on the underside of the coverslip.

Hi Apochronaut,
It is here viewtopic.php?t=3417.
(I googled it).
Peter.

Is it just me, or is he/she cross eyed?

Hi Jim,
I will tentatively suggest lacrymaria olor.
Hope this helps.

If I assume your desks are against the walls, how far from the walls are the fixtures? I'm guessing if I center the fixture between me and the edge of a 12'' deep shelf there would be shadowless light on the whole 24'' desk. In other words, 18'' from the wall. Since my ceiling is 9' I am considerin...

Hi Dale,
To add to my previous post; my microscopy room is 8' x 10', above each 8' wall is a 6' fluorescent tube, and above each 10' wall a 5' + 4' tubes. I've never had a problem with too little light.

Peter.

Hi Dale, In my microscopy room I fitted fluorescent tubes right round the wall ceiling junction with diffusers over, all on one circuit (switched together). This gives heaps of soft shadowless glare free light. I find it very good for working under and have never found a problem with reflections or ...

Anyone see the worm like microbe?
And the other video I posted...

Yes.

cpsTN wrote:With the camera view measuring 130 times larger than the direct-eye view at 30x, what is this telling me?

Your computer screen has a 4 1/3x magnification factor. If you where to connect the camera to an eighty inch TV what size would the "W" measure?

Peter.

Yes.

Hi Kambio, I have never tried this , however, Gray's "The Microtomist's Formulary and Guide" contains the following procedure (I have abridged). Smear a slight quantity of fresh egg albumen on a clean coverslip. Each individual protozoan is placed in the center of the coverslip and allowed to expand...

Hi Kambio, I have never sectioned these specimens, however; I am assuming you are cutting paraffin sections and flattening them by warming them while floating them on water on a slide. If this is so, I would drain the water from the slide, place it on a solid bench, cover with a piece of saturated f...

Hi Kambio,
If you give us some more information on your microtechnique we may be more able to help, (eg how are you flattening your sections, what are you using to adhere them to the slide).
Peter.

Hi Kambio,
Perhaps if you told us what your present microtechnique is we may be able to give better pointers.
Peter.

Hi Dale,
I recommend cushion vinyl on the floor, more comfortable underfoot and a lot kinder to dropped glass ware than concrete.
Peter.

what I was thinking was that once the images are reduced in size to about 0.8 Mp for display on an average computer monitor, then no matter what the camera sensor resolutions are, the images would end up being the same (assuming all other sensor/camera characteristics were identical ). This makes l...

I see from another thread that you now have this under control.
