Hach pH Platinum Series Flat-End Electrode
Description
Hach pH platinum series flat-end electrode with (2) electrolyte cartridges and manual
Features
- Flat glass membrane that hydrates easily, and has durability at high temperatures
- Double junction reference half-cell with a free-flowing outer reference junction
- Design ideal for use with samples containing sulfide or other substances
Details
frits as the junction between the reference half-cell and the sample. The porous material rapidly clogs with precipitated silver chloride, causing unstable junction potentials. The Flat-End pH Electrode uses a double junction reference half-cell with a free-flowing outer reference junction. The free-flowing junction provides nearly constant junction potential, greater accuracy and reliability than conventional porous junction electrodes, and is ideal for both routine and demanding applications.
The Flat-End pH Electrode contains a silver/silver chloride element in an inner chamber that contacts the electrolyte solution at an inner junction. Electrolyte flows from the free-flowing outer
junction at the electrode tip. This design makes it ideal for use with samples containing sulfide or other substances.
This Hach electrode uses a flat glass membrane that can be used at temperatures of 0 to 45 C, hydrates easily, and has durability at high temperatures. A moderate sodium error occurs at pH levels greater than 12.

Ocean acidification: University of Washington's giant plastic bags help control research conditions
With oceans becoming more acidic worldwide, scientists are getting creative in designing experiments to study them. For example, one group at the University of Washington is using giant plastic bags to study ocean acidification. Each bag holds about 3,000 liters of seawater and sits in a cylinder-like cage for stability. The group at UW, made up of professors and students, is controlling carbon dioxide levels in the bags over a nearly three-week period, during which they are looking at the effects of increased acidity on organisms living near the San Juan Islands. “These mesocosms are a way to do a traditional experiment you might do in a lab or classroom,” said Jim Murray, professor of oceanography at the University of Washington.

NOAA Alaska buoy network to monitor North Pacific ocean acidification
National Oceanic and Atmospheric Administration scientists detected signs of ocean acidification in the waters that hold the vulnerable and valuable fisheries of the North Pacific off the coast of Alaska, but they only had a snapshot of the action. “We know that in this place were important commercial and subsistence fisheries that could be at risk from ocean acidification,” said Jeremy Mathis, a NOAA Pacific Marine Environmental Laboratory researcher and professor at the University of Alaska Fairbanks. To understand how ocean acidification affects the North Pacific, NOAA scientists created a mooring network that collects constant in situ data on parameters contributing to acidification. They hope it will reveal seasonal trends and patterns left out by their snapshots.

ROVs Sparking Compassion and Curiosity at the Shedd Aquarium
This summer, the team from the Shedd Aquarium in Chicago began pilot programs designed to reach local communities in a new way. Specifically, they ran excursions on both Lake Michigan and the Chicago River using ROVs equipped with underwater cameras and other tools to introduce more land-dwellers to what lies beneath the water. Shedd Aquarium Learning Programs Manager Sadie Norwick and Communications and Public Relations Coordinator Kayley Ciocci spoke to EM about the Shedd's innovative ROV programming for the public. Inspiring conservation with technology Although the pilot programs using the ROVs were new in 2018, the Shedd team is no stranger to using ROVs to educate the public.
