The NEW Thermo Orion COD165 thermoreactor will hold 25 round glass vials with 16mm external diameter. It is designed for sample preparation in determining COD, total phosphorus, total nitrogen, total chromium and other parameters in water and sludge analysis. The Thermo Orion COD165 thermoreactor, paired with the Thermo Orion COD reagents and the Thermo Orion AQUAfast AQ4000 advanced colorimeter or Thermo Orion AQUAfast AQ2040 colorimeter, provide the user with a complete analytical setup for COD analysis. The Thermo Orion AQUAfast AQ3700 colorimeter also performs COD analysis, as well as
nitrogen and phosphate digestion methods.

The COD165 thermoreactor is designed to be highly resistant to chemical and mechanical corrosion. The heating block that holds the COD vials allows for very good thermal homogeneity at the selected temperatures. The temperature of the heating block is microprocessor controlled. The Pt100 temperature probe does not require any calibration, because when the instrument is turned on, a self test is performed.

The COD165 thermoreactor is equipped with a voltage selector for either 115 V or 230 V. It is accessible on the rear panel of the instrument. Always check the voltage setting before plugging the instrument into a power outlet.

This thermoreactor offers additional digestion temperature ranges which meet the COD and other digestion method requirements around the world. The temperature settings are 100, 120, 150, 160 and 165 degrees Celsius. The 160 C and 165 C are new. They are used for faster COD digestion methods where the digestion takes only 30 minutes!

The heating block is equipped with over-temperature protection by a thermostat, which turns off heating when the temperature exceeds 180 C.

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.

Treating Harmful Algal Blooms: A Natural Progression

Some of us happen upon the subject of our life’s work by accident, some of us are born into it, and some of us ease into it over time. For Tom Johengen, Research Scientist for Cooperative Institute for Great Lakes Research (CIGLR) and Director of Michigan Sea Grant , choosing to study Harmful Algal Blooms (HAB) was “a natural progression” from his days as a grad student investigating best management practices for controlling nonpoint source nutrient pollution. “I’ve been the research scientist with CIGLR since my postdoc in 1991, 31 years, and I’ve been the Director of Michigan Sea Grant for the past 3 years. 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.
