Please Note

All prices are in AU$ for delivery in Australia and New Zealand. If you are outside Australia or New Zealand, please refer to A-M Systems's web site for further information.
Delivery charges are approximately AU$50 with a delivery time of about 4-6 weeks. For urgent orders, we can obtain express shipping by courier from the USA, but this will incur a higher freight cost (please ask for details).
GST is not included.
Prices updated October 2004. Please note prices may be subject to change as a result of major fluctuations in the US$/AU$ exchange rate.
Wire sizes are nominal, and may vary a little from batch to batch. Please take this into account if you intend to insert the wire into a glass or metal tube.
