Compact and lightweight, the Solinst Peristaltic Pump is designed for field use. Ideal for water and vapor sampling from shallow wells and surface water. One easy-access control enables reversible flow and various speeds, which allows high or low-flow sampling. Pumping rates vary depending tubing size. Standard 5/8” OD (16 mm) silicon tubing delivers from 120 ml/min to almost 3.5 L/min.

Available in stainless steel or PVC, Solinst Bladder Pumps provide consistent, accurate, reliable groundwater samples in various applications. Ensuring no air/water contact during operation, pumps are ideal for VOC sampling. Teflon bladders are ideal for dedication. Inexpensive polyethylene bladders are also available. Pumps are effective at any angle, to depths of 500 ft (150 m), and are ideal for low flow sampling.

The Micro Double Valve Pump has a remarkably small and flexible design. It is a pneumatic pump that uses coaxial Teflon tubing to give high quality samples. It is small enough to fit in 1/2" (13 mm) tubing and channels of the Solinst Model 403 CMT Systems, as its diameter is only 3/8" (10 mm). Ideal for low flow monitoring in narrow applications.

The Model 464 Electronic Control Unit is available in 125 psi or 250 psi versions, and uses 4 AA alkaline batteries that last up to 100 hours of normal use. The 464 allows high or low flow sampling, and can be controlled manually if your batteries run out, using only a compressed gas source.

The Inertial Pump is a simple, reliable inertial pump that provides a cost effective sampling option for groundwater monitoring. The pump consists of a riser tube fitted with a one-way foot valve. It can be easily operated manually, or by using a surface pumping mechanism. The tubing and foot valves come in various sizes suitable for varying well diameters and sampling applications.

Model 425 is a stainless steel sampler, with LDPE tubing mounted on a convenient reel. Discrete interval sampling is ideal for obtaining truly representative water samples from below floating product layers, or for obtaining samples of the product itself. Can also be used to profile open bodies of water and boreholes, and to collect samples from distinct levels or points of inflow.

The Solinst Point Source Bailer is stainless steel and has dual ball valves, top and bottom. This prevents a sample collected at a discrete depth from mixing with water from other depths during retrieval. It is a simple and cost effective device for aquifer profiling, and collecting samples from distinct levels. Purging and disposal of purge volume can be avoided.

The Model 428 BioBailerâ„¢ is a low cost, biodegradable PVC bailer. The standard bailer holds more than one liter of sample. The rigid design will not bend and the top and bottom are tapered to prevent hang-ups in a well. The clear body allows a visual check of contents. A sample release device is included.

Simple, inexpensive packers inflate by hand pump and are available in 2 sizes. Designed for pneumatic inflation at pressures from 20-50 psi (140-345 kPa), are primarily used in 2" and 4" (50 mm and 100 mm) monitoring wells and other suitable smooth boreholes and wells. Convenient and easy to use in combination with Solinst Accessories for various sampling and monitoring applications.
