Electron Microscopy Sciences Glutaraldehyde 70% Aqueous Solution, 111-30-8, MFCD00007025, 10 mL ampoule
Formula: OCHCH2CH2CH2CHO, MW: 100.12. After glutaraldehyde has been purified to EM grade, it has a high risk of polymerizing if it is not handled properly. Electron Microscopy Sciences takes special precautions to assure a polymer-free, pure glutaraldehyde. 4 to (-18)°C.
Electron Microscopy Sciences Glutaraldehyde Aqueous 70%, EM Grade 2 ML
OCHCH₂CH₂CH₂CHO F.W. 100.12
Aqueous glutaraldehyde, the universal fixative for electron microscopy, is purified to EM grade from commercial grade by "all-glass vacuum-distillation". It is the highest possible quality, free from polymers and other contaminents. Each lot is assayed prior to shipping assuring consistent purity and the highest possible quality.
If stored properly, our Glutaraldehyde has a very long shelf life. 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 sealed under dry nitrogen and 100 ml bottles that are kept refrigerated until it is shipped.
Grade: EM Grade

Electron Microscopy Sciences 10% Glutaraldehyde in Acetone 10 ML
C₅H₈O₂
Rapid-Freezing on a polished metal surface, at the temp. of liquid helium or liquid nitrogen, followed by freeze-substitution in osmium-acetone, has been shown to be a very useful technique for capturing rapid cellular events and for preserving cell ultrastructure.
Visikol Inc Visikol HISTO-M Starter Kit
Laboratory Reagent, Histological Reagent, Tissue Clearing Reagent, Visikol HISTO-M Starter Kit. With the Visikol HISTO tissue clearing approach you are now able to rapidly and easily image tissues in 3D without damaging the underlying cellular morphology. The Visikol HISTO approach has been designed to pair with immunolabeling and is reversible so that 3D histology can be followed up with traditional 2D histology. The Visikol HISTO tissue clearing approach for 3D tissue cultures is comprised of one reagent called Visikol HISTO-M. In our Starter Kit we have combined 30 mL of Visikol HISTO-M with the four pre-treatment solutions required to process 3D tissue cultures for immunolabeling. All you need to do is add your immunolabels and nuclear stains. This kit comes with enough material to process three 96-well plates of micro-tissues.
Visikol Inc Visikol Plant Biology 100mL
Laboratory Reagent, Histological Reagent, Tissue Clearing Reagent, Visikol for Plant Biology, 100mL, A simple to use rapid tissue clearing formula optimized for botanical microscopy, Clears most tissues within 12 hours, Great for taxanomical morphological and pathological identification, Comes in a white HDPE bottle with black cap.

Electron Microscopy Sciences Paraformaldehyde, Prills 500 GR
(Polyoxymethylene)
OH(CH₂O)n H F.W. 600 Average
Paraformaldehyde is the condensation product of methylene glycol, a substance not so far isolated in its pure form; it is a white solid with a formaldehyde content between 78 and 98% and is supplied either as a Prill or Granular. All forms contain more than 95.5% paraformaldehyde content. The Prill and Granular forms are small, free-flowing, dust-free beads, the most desired by EM users.
