The Thermo Scientific Orion AQUAfast AQ3170 colorimeter kit measures free and total chlorine in the range of 0.02 to 2.00 mg/L, or 0.1 to 8.00 mg/L with short pathlength vial (included). Measuring free and total chlorine using the DPD method, the AQ3170 colorimeter and included reagents assist with EPA drinking water measurement requirements. The colorimeter’s Interference Filter uniquely narrows (targets) the bandwidth, creating accurate and reproducible readings. The included sample vials also help reduce preparation time by utilizing lid-attached light shields instead of a cumbersome sample chamber cover.

The meter kit includes a field carrying case, sample vials with light-shielding caps, a vial cleaning brush, 100 each of AQUAfast AC4P71 Free Chlorine and AC4P72 Total Chlorine powder reagent packets and batteries. The meter carries a CE certification and a two year warranty.

Caring for the Chesapeake: Supporting the Iconic Bay Starts with Good Monitoring Data

The Chesapeake Bay is enormous: the Bay and its tidal tributaries have 11,684 miles of shoreline—more than the entire U.S. west coast. It is the largest of more than 100 estuaries in the United States and the third largest in the world. The Bay itself is about 200 miles long, stretching from Havre de Grace, Maryland, to Virginia Beach, Virginia. But the Chesapeake Bay isn’t just enormous--it’s enormously important. The  Chesapeake Bay Program  reports that its watershed covers about 64,000 square miles and is home to more than 18 million people, 10 million of which live along or near the Bay’s shores.

When I began my postdoc with CIGLR we were just starting to study the impacts of the recently invaded zebra mussels.

The Coevolutionary Arms Race: Fungus-Growing Ants and Social Parasites

Despite the negative stereotypes surrounding social parasites, Rachelle Adams, Assistant Professor at The Ohio State University, knows just how important host-parasite relationships are to evolution. Like many ecologists, Adams, Assistant Professor at The Ohio State University, found her passion for nature in childhood. “It began when I was a kid. I had this general interest of nature, and I loved to spend time in the forest, exploring,” she recalls. Her desire to work with wildlife was solidified in college. “I didn’t know exactly what direction I was going to head in but the ecology and evolution classes I took were really central to shifting my perspective on ‘what is biology.’ It opened my eyes to seeing nature in a different way,” she explains.
