Choosing The Right Thermo Benchtop For Your Project
Thermo Scientific’s Orion Star A line is full of options for completing projects from environmental monitoring to quality control and beyond. These include benchtops like the Orion Versa Star and portables like the Orion Star A329 . Making the right selection is important for ensuring project success, but sometimes choosing a meter can be difficult. To make things a little easier, we talked with Ricki Hartwell, the global product manager for Thermo Scientific’s Orion Laboratory and Field Instruments. She gave some tips to help customers find the best meter to meet their needs. Let’s take a look at her recommendations for benchtops.

Charles River Algal Blooms Stop Swimming and Launch a Floating Wetland
The Charles River used to be a swimming hotspot for Cambridge and Boston residents. Decades of industrial pollution and nutrient runoff have degraded water quality and eliminated public swimming in the Lower Charles, but a movement is afoot to get Boston and Cambridge back in the water. One step toward the goal of a safely swimmable river—without the need to obtain a permit, as is now necessary—is detecting and managing the harmful algal blooms that appear on the river. An experimental floating wetland and new research and analysis of water quality data that shows a possible effective detection system for algal blooms on the Charles River are two new steps toward the goal of safe, accessible swimming.

Harnessing the Gulf Stream for Renewable Energy
The Gulf Stream, the massive western boundary current off the east coast of North America, moves water from the Gulf of Mexico north and west across the Atlantic Ocean. There’s a lot of energy in that much moving water and researchers are trying to put it to use. Although the Gulf Stream’s path shifts (researchers say it acts like a wiggling garden hose), in a couple of spots, it stays relatively stable. At one such spot off the coast of Cape Hatteras, North Carolina, researchers have dropped moorings and research instruments to study the current with the eventual goal of harnessing it for renewable energy.
