Glutaraldehyde 10% aqueous solution, EM grade (DG)

Glutaraldehyde aqueous solution is vacuum distilled and free from polymer and other contaminants. Each lot has been tested and assayed. Polymers re-form depending on storage time and temperature. Available in bottles or in pre-scored, snap-open, easy-break amber ampoules, sealed under nitrogen. Refrigerated, its shelf life is about one year, or freeze to prolong shelf life substantially. 

An arbitrary storage guide: deep freeze lasts 5 years; fridge freezer = 2 years. Fridge = 1 year, room temperature = a week or two.

Anhydrous glutaraldehyde (in acetone) is available, but it is a DG for shipping with a maximum shelf life of 6 months, refrigerated.

Store refrigerated at (-18) to 4°C

CAS # 111-30-8

Also available:
C001 and C002 Glutaraldehyde 25% solution
C003 Glutaraldehyde 50% solution
C00370 Glutaraldehyde 70% solution
C003701 Glutaraldehyde - See SDS for C00370 (above)

Shipping

As glutaraldehyde (GA) at these concentrations is classified as dangerous goods (DG) for shipping, this item will automatically be sent by road transport.

Shipping by air now incurs a DG cost of AUD250 to 400 (please request a quote). 

To avoid DG shipping fees, switch to prepared paraformaldehyde (pure formalin, C004) as the primary fixative, or use prepared 3% GA in buffer (not a DG), if possible. 

More info on shipping Glutaraldehyde

For road shipments, the challenge is to keep materials from reaching higher temperatures, if only for a limited time. We use insulation and plenty of ice. This is intended to extend the shelf life of the product only—glutaraldehyde at RT deteriorates slowly, and for fixation processes, it does not matter if it is kept for several days at room temperature. The exceptions are immuno- and histochemistry, in which case pure formalin is probably the better fixative.

We generally ship cold items on Mondays to reduce the number of days in transit.

Please choose the appropriate ice quantity to add to your order; extra ice may be needed for larger orders.

NT, WA, Tas are unsuited for shipping by road

3% GA already made up in buffer is available in 100 mL bottles, and that product can be shipped by air. See C008-B below.
