Problem description:

I used to have a hairy spider, and then I died. I really want to make it into a specimen, but I don't know how to do it. If you have any friends who know this knowledge, please advise. Thank you very much

Analysis:

Formalin bubble.

When we went to practice, insects used insect needles to make dry specimens on foam boards, spiders and crabs were anesthetized (spiders were anesthetized with ethyl acetate) and then soaked in formalin.

Is this furry spider as big as an egg? I also had a black furry one, very docile and clean. That's a female China jumping spider. After giving birth, she put an egg bag next to the light bulb and left.

I went to the lab to ask the teacher for medicine, and when it was fixed, I soaked it, so that I could keep it as it is, and it would always be like that. If you have no experience, you can go to any university and find someone who studies biotechnology, animal science and animal medicine to help you. When we practice, these three departments should study together.

Okay, information.

Formaldehyde HCHO, also called ant aldehyde, is a colorless gas with an odor of * * *. Soluble in water, 35% to 40% formaldehyde solution is called formalin. Formaldehyde aqueous solution has bactericidal and antiseptic properties. Diluted formalin solution (the mass fraction of formaldehyde is 0. 1% to 0.5%) is often used to soak biological specimens.
