The Best Sample Analysis Starts with the Best Sample Prep

With increased state regulations, cannabis growers are required to conduct trace metals testing to ensure a safe and high-quality product. This testing encompasses a wide variety of samples from growers and the processing industry such as soils. fertilizers, plant material, edible products, concentrates and topicals. Obtaining the analytical data required to produce quality products starts with the crucial step of sample preparation.

The Milestone ultraWAVE, uniquely equipped with state-of-the-art Single Reaction Chamber (SRC) technology, is the clear choice. With twice the throughput of traditional systems, the ultraWAVE digests up to 15 samples of any matrix simultaneously, offering labs new levels of user convenience, cost-efficiency and maximum productivity. The ultraWAVE delivers superior sample quality, too, ideal for state-mandated metals analysis.

With our high pressure and high throughput rotors, stainless steel construction and patented vent-and-reseal technology, the ETHOS UP ensures market-leading safety, productivity and flexibility for trace metals analysis in cannabis testing laboratories.
