Tissue Fixatives
Newcomer Supply Bouin Fluid, 1 Liter
Newcomer Supply Bouin Fluid is a ready-to-use picric acid based fixative combined with acetic acid and formalin. Bouin Fluid penetrates rapidly, fixes evenly, provides crisp nuclear staining and preserves structures with soft and delicate features. Shelf Life is 2 years from date of manufacture. Store at 15-30°C. Bouin Fluid is recommended for a variety of specimens including bone marrow clots and biopsies, gastrointestinal tract biopsies, testicular biopsies and lymph nodes. It also serves as both fixative and mordant for tissues stained with trichrome procedures.
Electron Microscopy Sciences Hard Plus Resin 812 Kit
Hard-Plus Resin-812 is a newly formulated resin that enables the processing of specimens that have a tendency to wrinkle and be problematic. WPE numbers do not vary much from batch to batch, there is good stability under the electron beam, and it stains well with heavy metals. Viscosity is lower than original Epon-812, making infiltration of tissue more complete.
For processing and embedding, it can be used same way as Epon-812, but it is not necessary to use intermediate solvents and infiltration can immediately follow with absolute alcohol.
Polymerization normally at 60 degree C for 2448 hrs. Longer times or higher temps (+70 degree C) will give harder block. For larger samples (>1x1 mm3) use of intermediate solvent recommended. Supplied only as a premix kit. Each kit contains five separate mini-kits, making approximately 100g each.
Includes: 5x50g Hard-Plus Resin-812, 5 x 50g Hardener Hard-Plus, 5 x 2.5 ml Accelerator

Electron Microscopy Sciences Bouin's Solution, 1L
Bouin's solution can be used as a fixation and a staining fluid. Bouin's fixative is excellent for use on biopsy specimens of the gastrointestinal tract. Tissue from the endocrine system are well fixed and many antibodies react well with tissue fixed in Bouin's. Bouin's solution may be used as a routine fixative or a staining solution, but should not be used as a preservative for tissue. Tissue cannot be held in Bouin's solution for extended periods. The maximum fixation time in this solution should be less than 48 hours and should be transferred to alcohol. Packaged in leak-proof histo-containers, prefilled and ready-to-use.The solution is formulated with Picric Acid saturated aqueous solution 75%, Formalin (40% aqueous formaldehyde) 25% and Glacial Acetic acid 5% in de-ionized water.
