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 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.

Formulated with Picric Acid saturated aqueous solution 75%, Formalin (40% aqueous formaldehyde) 25% and Glacial Acetic acid 5% in de-ionized water.

The Fixative for Use in Fixing Cornea

arrow12CoreDish™ Multiple Biopsy Containers Half Prefilled with 10% Formalin

Few recommendations concerning how the biopsies should be handled have been published. Performing a large number of biopsies means an increase in the number of containers handled and consequently a technical overload of the transmission network, which occurs without any financial counterpart. A new approach had to be developed in order to increase productivity.

We are proud to offer a multi-compartment container in the shape of a dish and half prefilled with 10% Neutral buffered Formalin, for holding and transporting biopsies. It is supplied with a leak-proof closure with O-ring ensuring total protection of contents. It conforms to OSHA directives. These CoreDisn™ measure only 15mm H x 95 mm Diameter. Each compartment is clearly identified to allow proper placement and visualization of the biopsy being inserted. Thanks to CoreDish™ it is no more necessary to use a multiple of individual containers, thereby reducing cost and risks of confusion.

CoreDish™ available in many configurations to serve in different biopsy, such as prostate, upper GI tract and lower GI tract. A label allows recording the related information, patient ID, doctor, date and time.

arrow12 Glutaraldehyde

OCHCH2CH2CH2CHO F.W. 100.12 CAS #111-30-8
Specific Gravity @20/20°C: 1.131

EM Grade Distillation Purified
  • The Universal Fixative for Electron Microscopy.
  • Purified to EM Grade from commercial grade by "all-glass vacuum-distillation."
  • THE HIGHEST PURITY, free from polymers and other contaminants.
  • Each lot is tested and assayed in our lab before we ship and guarantee its purity.
  • Sealed under dry nitrogen.
  • Refrigerated prior to shipment.

After glutaraldehyde has been purified to EM grade, it has a high risk of polymerizing if it is not handled properly. Electron Micro-scopy Sciences takes special precautions to assure a polymer-free, pure glutaraldehyde.

Every lot of our EM grade aqueous glutaraldehyde is assayed prior to shipping assuring you consistent purity and the highest possible quality. If stored properly, our Glutaraldehyde has a very long shelf life.

We package our aqueous glutaraldehyde in 10 ml, single dose ampoules, sealed under dry nitrogen, and kept refrigerated until it is shipped. We offer our glutaraldehyde in a wide range of percentages to simplify mixing procedures and avoiding waste.

EM grade aqueous glutaraldehyde, stored in volumes greater than 100 ml, with repeated defrosting and recapping, will polymerize in time, producing an absorption peak of 235nm rather than the 280nm of pure EM grade. The presence of polymerized glutaraldehyde greatly reduces its efficiency as a cross-linking agent, preventing proper fixation. For this reason, we provide 10 ml ampoules and 100 ml bottle quantities for larger applications.

arrow12HISTOCHOICE™MB® *- The Molecular Biology Fixative

  • SAFE - Contains no Formaldehyde, Glutaraldehyde or Mercury.
  • NON-TOXIC – Is completely odorless and can be safely disposed
    of down the drain.

HISTOCHOICE™ MB® Tissue Fixative is the first fixative designed for the molecular biologist. It is specialty formulated to preserve antigenic sites for antibody probes and nucleic acid sites for immunohistochemistry. HISTOCHOICE™MB® replaces formaldehyde based, alcohol based, Zenkers, B-5, B-3, Bouin’s and other fixatives with superior results. Tissue fixed in HISTOCHOICE™MB® exhibit vibrant staining, better nuclear and cytoplasmic detail, and will retain a crisp appearance even after long-term fixation.

Because this formula is designed specially for molecular biology applications, HISTOCHOICE™MB® fixed sections do not require pre-digestion or other recovery procedures to make important sites available.This means you spend less time preparing slides and more time doing research.

More than a fixative, HISTOCHOICE™MB® is a preservative that leaves antigens and nucleic acids in their native state, allowing binding for specific probes. Primary antibodies can often be diluted several-fold due to the increased number of preserved antigenic sites, saving cost
on every slide you process.

HISTOCHOICE™MB® fixed tissue retains a much more natural look and feel than formalin fixed tissue. It is important to remember that these tissues are not fixed by formalin, but rather preserved by HISTOCHOICE™MB®.

arrow12Hollande’s Fixative

A modification of Bouin's solution. It is stable and will decalcify small bone specimens. Tissue that is fixed with Hollande's can be stained successfully with most stains, and the cupric acetate in the solution stabilizes red blood cell membranes and cosinophil and endocrine cell granules so that less lysis occurs than with Bouin's solution. Hollande's is widely used as a fixative for biopsy specimens of the gastrointestinal tract.

Thorough washing of the fixative prior to placing the specimen in a phosphate buffered formalin solution is necessary because the salts present in the solution will form an insoluble phosphate precipitate. Packaged in leak-proof histo-containers; prefilled ready-to-use.

15560arrow12Mirsky’s Fixative™

  • Saponin/Glyoxylate Fixative
  • Preserves Immunohistological activity
  • Contains no formaldehyde
  • Fast-acting

Mirsky’s Fixative™ is a superior fixing agent for use in immunohistological and immunological protocols. Mirsky’s contains no formaldehyde or glutaraldehyde. Therefore, it has considerably reduced toxicity and virtually no odor. Mirsky’s Fixative is neutral, buffered, and isotonic (308 mOsmol). Additionally, Mirsky’s Fixative does not contain toxic or hazardous buffers such as cacodylate or barbital. Hardening or shrinkage of tissue is considerably reduced.

Double reactive sites afford excellent cross-linking properties while maintaining sample enzyme activity. Samples processed in Mirsky’s Fixative for light microscopy can subsequently be used in electron microscopy procedures. Special buffer systems may be used in place of the buffer provided.
Use as replacement for formalin and/or glutaraldehyde fixatives in immunohistological and immnocytological staining protocols. Tissue size is unlimited, as long as the sample is no thicker than 0.5cm in at least one plane to assure uniformity of tissue penetration. The gross visual appearance will be different than in formaldehyde and tissue may seem “raw”. This is due to double site binding of the fixative with a resultant reduction in tissue shrinkage. Microscopic examination of tissue morphology will be noticeably improved. This material is intended to maintain enzyme and antibody activity. For best results, tissue section of high digestive enzyme content should be thoroughly rinsed in saline solution before fixation (e.g. trypsin in intestinal samples). Once fixed, tissue may be retained in Mirsky’s Fixative and ethanol indefinitely.

Mirsky’s Fixative is normally distributed as a concentrated two bottle system, although high through-put laboratories often use the single bottle ready-to-use format. The two bottle system is comprised of Mirsky’s Fixative 10X Concentrated and Mirsky’s Fixative 10X Buffer. To reconstitute to working strength, add 1 part Mirsky’s Fixative 10X Buffer to 8 parts distilled or deionized water, mix thoroughly, then add 1 part Mirsky’s Fixative 10X Concentrate and mix again.

The two bottle system has a shelf life of 12 months while the ready-to-use format has a shel life of 30 days.
