The SP200 variable speed portable peristaltic pump sampler is ideal for sample removal from shallow wells and surface water, including lakes, ponds, and holding pools. The water sampler is lightweight, rugged, easy to use, weather resistant, and requires minimal maintenance. The peristaltic pump is designed to take a manual sample and has the ability to back flush the sample hose once you are finished taking the sample.
The water sampler operates using an external 12 volt DC power source that can supply at least 2 A continuous. The variable speed motor is reversible and can sample at any speed from a trickle up to 500 ml per minute. A power cord, 10 ft (3.05 m) long, is included with each variable speed peristaltic pump sampler. The power cord is fitted with alligator clips for easy connection to almost any 12 volt DC battery, such as a car battery or a small 12V, 5 AH gel cell.
To provide high sample integrity, the water sample only contacts the norprene and polyethylene tubing. The tubing is easily cleaned or replaced. To avoid cross contamination or lengthy decontamination procedures simply change the inexpensive tubing between samples.

In The News
In 2012, for maybe the first time, Lake Superior got scummy.
Visitors to the Apostle Islands National Lakeshore reported algae washing up on shore around the park.
It was a marked shift for the park, made up of a portion of the Lake Superior lakeshore and nearby islands. The water surrounding the park is cold, clear and typically low in nutrients: a combination unlikely to result in algal blooms.
But, in 2012 and again in 2018 after violent storms, major algal blooms—ones observed over multiple days—washed ashore and clogged the beaches with unsightly, scummy algae.
Not the usual suspects
The algal blooms of Lake Superior are not the algal blooms of warmer, more nutrient-rich lakes like Lake Erie.Read More
*This is part two of a series on changing ancient lakes. See part one, Lake Baikal, here .
Ancient lakes are facing a suite of rapid, unprecedented anthropogenic changes. While ancient lakes are spread around the world and vary widely from lake to lake, their incredible age, which can reach into the tens of millions of years, makes them unique resources to science.
They host incredible biodiversity and long sediment records. They are vital sources of food and water for millions of people. In a changing world, ancient lakes’ value as scientific and natural resources and the incredibly diverse life they contain is under threat.Read More
*This is part one of a two part story on ancient lakes. Part two , Lake Tanganyika, available here.
Lakes that have supported human settlements for thousands of years are starting to feel humans’ effects in rapidly developing and significant ways.
From climate change to nutrient loading to plastic pollution, ancient lakes are straining under some of the least welcome contributions of humanity. The changes could have consequences for the diversity of life within the lakes and the human populations that rely on it.
And, while ancient lakes have been around long enough to weather past climatic changes, the changes occurring now are so rapid, the end result is uncertain.Read More
