Glutaraldehyde 50% solution, biology grade (DG)

Vacuum distilled, free from polymer and other contaminants.

Every lot has been checked and analyzed.  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. It has a shelf life of around a year if refrigerated, or it can be frozen to significantly extend the shelf life.

An arbitrary storage guide: 

Deep freeze last 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.

CAS # 111-30-8

Also avilable:

C001 and C002 Glutaraldehyde 25% solution
C003 Glutaraldehyde 50% solution
EMS16500 - Glutaraldehyde 50% Bio grade
C00370 Glutaraldehyde 70% solution

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 quote). 

To avoid DG shipping fees, switch to prepared Paraformaldehyde (pure formalin, C004) as the primary fixative , or use C008-B  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, and 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 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 you your order; extra ice may be needed for larger orders.

Qld - 1 kg ice

ACT, NSW, SA, Vic - 2 kg ice

NT, WA, Tas - unsuited for shipping by road
