Overview
The Solinst Model 407 Stainless Steel Bladder Pump allows consistent, high-quality samples in all types of applications. It offers excellent performance and reliability. With Bladder Pumps there is the assurance that there is no air/water contact during sampling. It meets the most rigorous US EPA standards for VOC groundwater monitoring.
Mechanics
The bladder ensures that drive air or gas does not contact the sample, thus avoiding degassing or contamination. Pumps are rugged and long-lasting. Teflon bladders are ideal for dedication, while less expensive polyethylene bladders are available for those who prefer to change bladders after each use. Bladders and intake filters are easily replaced in the field in just a few minutes. No special tools are required.
Design
The Solinst Model 407 Stainless Steel Bladder Pumps are manufactured from 316 stainless steel and have Teflon check balls. The bladder most frequently used is Teflon, however polyethylene bladders are also available. This is the ideal sampling pump for most types of municipal, industrial and general environmental applications, especially where VOC analysis of the sample is important.
The pump body of the standard Integra is a convenient 1.66"" dia. (42 mm) and comes in lengths of 2 ft and 4 ft (0.6 m and 1.2 m). 1" dia. (25 mm) bladder pumps are also available for narrower applications.
Applications
Excellent for either regular flow or low flow sampling, the stainless steel pumps can lift from depths up to 500 ft (150 m) below grade.
For metals analysis and situations with highly corrosive liquids, the PVC bladder pumps are more suitable. It has Teflon check balls, a porous polyethylene screen and may have either a Teflon or a polyethylene bladder. The low cost of the PVC pump also makes this a perfect choice for situations where there is a limited budget, but dedicated bladder pumps would be preferred.
Benefits
- High-Quality Samples: Consistently accurate samples with excellent VOC sample integrity.
- Simplicity: The controller, air compressor and flow-through cell can be easily transported by one person to any site. Hookup to the pump is by compression fittings. Low purge volumes ensure rapid sampling.
- Cost Saving: Reduced need for repeat sampling and shorter time required for each sampling round.
- Bladders: Durable Teflon bladders are ideal for dedication. Inexpensive polyethylene is also available.

Solinst groundwater samplers: Versatile options for a variety of applications
Groundwater sampling can be a challenging task that requires different tools for different applications. Solinst groundwater samplers offer the capability to obtain commonly needed representative samples of groundwater using different approaches of water withdrawal. Solinst’s 425 Discrete Interval Sampler uses passive sampling to grab water from a specific depth. The 407 Bladder Pump enables continuous airtight low flow sampling. The 408 Double Valve Pump can continuously sample at variable rates. “One sampler isn’t necessarily going to be for every site,” said Randy Blackburn, Solinst product manager. Each has different means of fluid sampling. The 425 sampler relies on a manual air pump that pressurizes the sampler based on the water depth.

Climate Change and Microplastics: Monitoring Lake Champlain
Most people go to Lake Champlain for its exceptional views and thrilling boating, but it’s also home to a wide variety of interesting aquatic research projects. From studying microplastics to thermal dynamics of the lake, Timothy Mihuc, director of the Lake Champlain Research Institute (LCRI) at the State University of New York at Plattsburgh (SUNY Plattsburgh), has spent his career studying aquatic ecosystems. As an aquatic biologist, he’s the main investigator on Lake Champlain’s research studies while also managing their grants, employees, and their hands-on buoy work. Over the years, LCRI has received a number of environmental grants that aid in its monitoring research.

Current Monitoring after the Francis Scott Key Bridge Collapse
On March 26th, according to The Baltimore Sun , a 984-foot, 112,000-ton Dali lost propulsion and collided with a support column of the Francis Scott Key Bridge, collapsing the structure. Soon after the event, search and rescue, salvage crews, and other emergency responders were mobilized after the collision. As salvage efforts progressed in early April, NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS) responded to a request for real-time tidal currents data and deployed a current monitoring buoy—CURBY (Currents Real-time BuoY)—into the Patapsco River north of the Francis Scott Key Bridge.
