HACH CHEMISTRIES, REAGENTS AND STANDARDS Hach® has more than 60 years of history dedicated to formulating and packaging high-quality reagents for water analysis. We understand your applications and formulate our reagents to ensure exceptional performance and deliver results you can trust, time after time. Our expertise extends beyond chemistry formulation to the complete reagent system. Hach chemistries are rigorously tested in combination with our packaging and instruments to ensure the highest possible system performance. No other company can offer these advantages.

Powder Pillows are available for a large number of parameters and measuring ranges. Hermetically sealed in aluminium foil pillows, the Permachem reagents have a shelf life of many years. The reagent is simply poured into the measuring cuvette together with the sample. The evaluation can be carried out visually, e.g. with a colour disk, or with a Hach photometer.

The Swiftest is a powder dispenser that releases the correct amount of DPD (N,N-diethyl-p-phenylenediamine) at the press of a button. It contains enough reagent for 250 chlorine tests (free or total chlorine). As a practical, attractively priced alternative, the Swiftest is ideal for laboratories with a high sample throughput, and for analysis in the field.

The secret of the Accuvac is the vacuum in the sealed glass cuvette containing a measured amount of reagent. The test is carried out by immersing the tip of the Accuvac in the sample, then breaking it by applying moderate pressure. The vacuum draws the sample into the cuvette, whilst ensuring thorough mixing. The resulting colour is measured visually or photometrically.

SL1000 PORTABLE PARALLEL ANALYSER (PPA) Water quality testing. Dramatically streamlined. The new Hach® SL1000 Portable Parallel Analyser (PPA) performs common water tests with less than half the manual steps. It produces highly accurate results with less opportunity for errors in a fraction of the time and allows for up to six parameters to be tested simultaneously. Less variability Avoid manual steps that can introduce variability, even when performed by experienced testers. Automation and internal temperature control make the entire process consistent and repeatable, while applying the same processes...
