Glutaraldehyde solution, Bio. Grade 25% (DG)
Vacuum distilled, 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 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.
Store at refridgerated 4 to (-18)°C
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 prepared 3% GA in buffer (not a DG), if possible.
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
3% GA already made up in buffer is available in 100mL bottles and that product can be shipped by air. See C008-B below.
