Entomological test tubes for storing insects genitals

you can find an office that sells medical equipment. They have all sorts of test tubes-from the smallest to not the smallest ))

There are Genitalia Micro Vials here
http://www.insectnet.eu/field_equipment.php

So who are we sending to Krakow?

Who needs how much?

And what is real?
There are 2 sizes, packs of 100 pcs. Well, I still have a package of each...
Can you use vandals for nets?

I just bought from this friend, the channel can be said to be established

ok. So - do you "rent out" the channel, or through you?

Since there is nothing special to pass, I took it directly, it turns out-through me.

Denis, can I order 200 pieces of 21 mm?

2 Yakovlev:
you can of course

To all:
We do this if you agree: you send me a list of necessary equipment in PM, I order it, pay for it, receive it and send it by mail (cash on delivery, your small interest is included)

Denis, can I order 200 pieces of 21 mm?

And how much will they cost?I need them too.

How much you need and what - in the personal account.
About the cost-throw 10%. However, I do not yet know how much it will cost to ship to Ukraine.

And how much will they cost?I need them too.

If I were you I would take a bus to Cracow

Roman, should I order it for you?

Of course!!! I'm in the middle of a continent. And the flu. What is Krakow like here? All trust is sent to Yandex. Mail.

Gentlemen, The other day, friends bought me plastic test tubes (used in microbiology) with a lid. When you close the test tube, the lid is flat. Unfortunately, they don't suit me. I'll pay you back at cost price.

You need to figure out how to attach them to an entomological pin.

Specifications:Length = 40 mmDiameter = 10 mmVolume = 1.5 ml
In a package of 500 pcs. The package price is 980 rubles. Made in Germany. Maybe someone needs it

Here are their photos:

- Yes, you can buy ordinary "Eppendorfs"from us (in the Russian Federation)

I would also not refuse to put Spheridiums, and without opening the genitals it is impossible.

Hello, Denis!
I also need plates for beetles
GBP 001, 002, 003 004 200 pieces of each variety.
I will be very grateful to you!

And what kind of records, dies?

It looks like my previous message is missing...

I placed an order last night from a Pole.

I will try to spoil the beauty and convenience of an industrial approach to business with my own "primitive handicraft"…
This is for those who don't want to (or can't) buy ready-made items. I do not offer anything new – all this is well known to colleagues with experience, so this post will be (if at all) interesting except for "neophytes". But still...
At first, I kept the genitals of butterflies like this:



The material is a tube cut into pieces from a dropper (ordinary, "hospital"). But very quickly abandoned this method because of its extreme inconvenience – to remove the genitals, you had to remove the "test tube" from the pin. Uncomfortable, long and constantly afraid to hurt the butterfly… As a result, I came up with a different method, which I wrote about in the topic "preparation of genitals" (http://molbiol.ru/forums/index.php?showtopic=154242&view=findpost&p=961721). It looked like this:



At first, I sealed one end of the tube with a lighter (as in the photo), and then I realized that there was no point in this and stopped sealing the tubes. The genitals were now easily removed with a hook-shaped pin and just as easily placed back. But the question of glycerol evaporation was raised on the forum. At first I was indifferent to this, and then I thought about it… I didn't want to complicate the process too much, or make it more expensive. The result is this. The idea was submitted by the author of post #1 in this topic (THANK YOU, Nikita Sergeevich!). I make the boxes myself. For the bottom lining, I buy this kind of garbage on the market (this is a piece from a sheet measuring 1.5 X 1 m):



They sell this shit together with styrofoam as insulation for walls. The saleswoman called it "polypropylene", but what it really is-I do not know (well, I do not know! The piece is much denser than styrofoam, does not crumble. If you stick minutes into it – they bend. Regular pins don't. From the scraps with a knife, I cut short strips with a square cross-section, the diagonal of which is slightly (JUST A LITTLE) larger than the inner diameter of the "test tube" - so that it fits more tightly. The result is this gizmo:



And this is what it looks like in action:



The test tube is easily removed from the "cap" (the cap, of course, remains on the pin), the genitals are removed with a hook under the binocular and after work they easily return to the bottom of the "test tube", which, in turn, is put back on the cap.
I use this method only nothing-only 2 weeks, "preserved" only a dozen and a half genitals (fatheads, pigeons), but it seems to me that I will use it for a long time… I won't transfer drugs from test tubes No. 2 to these ones yet. If the glycerin starts to dry out, then...
All this, of course, does not look as beautiful as industrial products, but "for yourself" - it will go all the way at a run!

Won't the glycerin dry out? Let it be slower. Tightness, as I understand it, still does not work.

Right. Absolute tightness, really not. But it is still more than in previous versions! During the entire time of using the previous version of the test tubes, nothing has dried up (I specifically looked at the wells that are 2 years old). K. A. Efetov generally stores genitals in open plastic wells (a rectangle with a hole about 3 mm in diameter and 2 mm deep) and nothing is lost! And this is for the devil knows how many years... At least, when we met (5 years ago), he already used them "along and across". Well, let's say in 5 years the amount of glycerol may decrease... I think that once every 5 years there will be time to look through the boxes, and where it is necessary - add a syringe of glycerin. All the same - you need to keep track of the collection! Even if it really dries up (for example, I will spend 10 years in prison), the genitals will not be lost. The advantage of this method is its cheapness and accessibility. If you don't like it, buy the factory ones... And I will be satisfied with such things!

EUPARAL!!!!!!!!!!!!!!!!!

EUPARAL!!!!!!!!!!!!!!!!!

"TO EACH HIS OWN"

They say this phrase was on the gates of Buchenwald... Maybe euparal is good... If it's cold, I haven't used it yet. Maybe I'll mature sometime... While practicing "on cats"

I just received a message that the order from Poland has been sent.

To Pavlosru4ko; Have you tried plugging it with cork plugs???

The cork plug will be difficult to pierce with a pin.

There is a proposal to use the same one-sided sealed tube, but slightly smaller in diameter, instead of a "stick" made of this polypropylene. Based on the "mom-dad" principle. And the main thing is that you can easily shoot "mom". Still, you need to make two tubes and the pin may rust from contact with glycerol vapors. I scribbled this in a minute in Paint:

There is a shilo

the pin may rust from contact with glycerol vapors.

Since when, say a glycerin pin will rust, it is not a corrosive substance

Rust and more like it!

Yes, they rust. Let the chemists explain.

Yes, they rust. Let the chemists explain.

Glycerin is quite hygroscopic and always contains water. This is what causes corrosion. In order to avoid it, you need to pre-dry the glycerin in a desiccator over dry alkali or other powerful drying agent.

And if the "dad" is stuffed with a sealed end?

It won't work. At least I have a sealed tip of a polyethylene (NOT silicone) tube, compressed with tweezers, wider than the tube itself.

And if a piece of tube is heated in the center, slightly stretched and twisted along the axis? You will get a tube fused in the center without flattened ends. Then we cut the sealed place in two...
