Tissue Pro - 10% Neutral Buffered Formalin (NFB) Ready-to-Use Histological Tissue Fixative, Formaldehyde Wet Specimen Preservation, Research, 1 Gallon

Got this to put my placenta in a jar and preserve it after giving birth. It’s been a month and so far so good. 10/10

Thanks

Using to preserve wet specimens. Works exactly how it's supposed to.

Very fast shipping. Got my formalin before the expected date. Product is just as advertised. Thanks!

I got the package early which was great, but I gave it 3 stars because when I received the item and opened the box, there was liquid outside the bottle. It was wrapped up in plastic, but if it wasnt, I would have gotten formalin all over my hands and table, which would have been extremely dangerous for me and everyone else in my house. I'm not sure how it leaked because the seal was still on the cap, but I'm very upset that formalin leaked out. After a few hours, I knew that there was no holes and it didn't leak anymore. So I'm not sure how or why there was formalin outside the bottle.
