Tissue Pro - 10% Neutral Buffered Formalin (NBF) Ready-to-Use Histological Tissue Fixative, Formaldehyde Wet Specimen Preservation, Research Chemical

Works amazingly. Make sure to use your PPE with this. Gloves, a mask, and work only in a well ventilated area, this stuff is toxic when inhaled, that goes for pets too. Don’t worry, they’ll be fine if they accidentally get close but do NOT let them eat it and do NOT dump it out after. You must take any leftover to a toxic waste disposal and/or ask your city what they want you to do with it. Make sure you’re injecting under the skin in as many places as you can/ all organs when preserving wet specimens!

Perfect! Great for preserving wet specimens.

Bought to start my wet specimen journey and I love it so far!

Did what it was supposed to do. I got several small specimens done with two soaks and injections with this bottle (much more than pictured). It was clearly labeled. When it arrived I felt like the packaging was minimal for such a hazardous product, but there were no leaks. The bottle is nice and thick, so it doesn't feel flimsy, which is important when having hazardous products at home. I used the original bottle to dispose of the used soaks and my waste plant took it without issue.

Use this in a jar that I put a fish head in. Fish head is still preserved product works and it's been at least 7 months.

Great for what I needed. Keeps things safe

Works like a charm

Works great!
