Ruthenium Tetroxide
0.5% stabilised aqueous solution.
no. R1027

Description

0.5% stabilised aqueous solution.

Ruthenium tetroxide is very similar to osmium tetroxide and is used as an EM fixative/stain.
It gives excellent staining of saturated and unsaturated polymer materials with improved image contrast.

RuO4 also has a stabilising effect against electron beam damage of material films.

Note: penetration of ruthenium tetroxide into tissue is poor.

Store at 4 °C.
5 x 10ml ampoules.

Product
Glutaraldehyde
Glutaraldehyde is used in biological electron microscopy as a fixative, several grades are available.
no. R1009 to R1314

Description

Product Description

Several grades of fixative are available:

Practical grade which is used for general fixation:
EM grade for use in electron microscopy. It is stable for over six months, has a pH 5 – 6 and proves to be an excellent fixative for structural studies.
It should also be used in histochemical or immunological reactions.

Double distilled grade which has a very low cation concentration:
Vacuum distilled grade is purified to remove all polymerised material and has no UV absorption at 235nm. It is packed in neutral glass under nitrogen for best results with enzyme histochemistry.

Any distilled glutaraldehyde is relatively unstable and has a high risk of polymerising if it is not handled properly.
It is therefore recommended that this grade of material is only purchased for use within a 3 to 4 week period and is carefully stored at 4 °C without continued defrosting and recapping.

Osmium Tetroxide
Osmium Tetroxide, OsO4, is a useful chemical compound that finds application as a staining and fixing agent for use in electron microscopy.
no. R1015 to R1024

Description

Osmium Tetroxide, OsO4, is a useful chemical compound that finds application as a staining and fixing agent for use in electron microscopy, as well as a chemical catalyst for the synthesis of specific organic chemicals.

The chemical properties of Osmium Tetroxide are such that use and handling of the chemical is often considered daunting. Although its volatility and toxicity certainly makes it a dangerous chemical, but when following the proper procedure and taking the necessary precautions, Osmium Tetroxide can be used to its full potential with limited risk to the user.

This is more toxic than glutaraldehyde and has a higher vapour pressure. Particular care must be taken to avoid breathing the vapour or allowing it to affect the eyes. Please refer to the technical data and the MSDS.

Supplied in sealed ampoules.
