Preparation of genitals

I think that Barko could organize a master class - because his drugs are great

I haven't seen all of his works, but judging by what is displayed in this topic (post # 99, # 129, etc.), this is probably the case...
By the way, what about large, or" branched " genitals, such as in the male Hipparchia pellucida (Stauder, 1923)? I can't imagine how they can be "rolled up" in euparal? Although, to be honest , I myself have NEVER tried to work with euparal, and I have no right to judge, since I have only seen it in a bottle... I'm still a "caveman"...

You can handle large genitals. It is more difficult with "branched" ones. So far, there is no good solution for the genitals of male bull whiskers. They are voluminous. Their structure is such that they cannot be placed in the same plane under the cover glass without deformation. I think a suitable solution will eventually come.

Oleg, and if you roll up the glass with a hole? (sorry that I don't fit into my diocese:)).

Yes, Denis had such an idea. I even found slides with a hole in them. There are a number of obstacles here. For large daytime images, the depth of the hole is not enough, the hole gives optical distortions when photographing, and the cost of one such glass is about 1.2 euros. This is not the way to go. Thank you for showing interest and taking part!

The fact is that the holes are different, both in shape and depth, and in the type of surface. There are matte ones, they probably distort, and there are polished ones. I just use the holes myself to view endophallus and am quite satisfied. And as for the price, for 1,2 oiropcs, they not only should not give distortion, but they are also required to straighten the drug and dance chardash! Buy Russian for 6 rubles!

.. In fact, the same parasitofauna of insects is almost not studied. ...

In continuation of the topic ... It's not the first time I've found a living organism in the belly of a shovel. It looks a bit like a crustacean.

And what to do if there is no alkali and there is no way to get it?

And what to do if there is no alkali and there is no way to get it? Is there anything you can replace it with? For example, I heard that the so-called "Mole" for cleaning pipes is 70% alkali. Can it be used?

I had to determine the dustpan at home, there was no lye, I experimented with "Mr. Cleaner" - a means for removing fat contamination.
Composition:water, surfactants, alkaline and organic solvents, emulsifiers. The result is acceptable, the scoop boiled for 3-5 minutes, as in alkali. I didn't notice any difference.

Can you see the result of such frying?

Need: aroma lamp (available at any pharmacy)

test tubes crack,

I have long abandoned the actual cooking - it is dangerous for the drug (test tubes crack, very easy to digest, etc.) and inconvenient (messing around with an open fire in the room, especially considering that I usually work at home...). The drug is immersed in an alkali solution and kept for the right time (usually 12-24 hours, sometimes more). IMHO, the only negative is a long wait.

I cook in a water bath (intermediate version). Cooking lasts 30-50 minutes.

In general, it is difficult to" bury " the moment, you need to try here.

And how long does it take for the alkali to boil?
Looking at the installation, it seems that the boiled lye will get out... In vitro climbs, why not here?

Can you tell me the best way to cut cover glasses? You need narrow strips with parallel edges. Sometimes you just need to cut an even piece.
