What We Offer

[Note – We are moving to the South Island during November/December 2020 so supply and delivery of products may be limited until late January 2021]

Alchemists are a provider of specialist production and design services for environmental monitoring and research equipment.  We pride ourselves on providing equipment made of robust materials crafted to a high standard to withstand the rigours of field sampling.  Our equipment is made by our two person team in Rotorua.

We have some standard products which are primarily focused on equipment used for sampling in rivers, streams, lakes and estuaries.  A quick summary of our standard products is provided on this webpage however take a look at our latest Product Brochure for more details.

We also provide replacement nets for most of the products we sell.

In addition to our standard range we can provide “one-off” custom designs for a particular process or project.  Our brochure (above) provides some examples of what we have provided as “one offs” in the past.

So give us a shout to obtain more detailed information on our standard products as well as our current prices or to have a yarn about a potential custom design to see if we can help you.

To make contact email us at info@alchemists.co.nz or give Tony a ring on 021 911953.
