Solinst Model 425 Discrete Interval Sampler

Key Features

• Avoids purging and disposal of purged water
• Obtain high quality discrete zone samples
• Profile wells or open bodies of water

Overview
The Solinst Model 425 Discrete Interval Sampler is a stainless steel groundwater sampler designed for use with LDPE tubing mounted on a reel. The reel has a pressure attachment for a high-pressure hand pump and a pressure/vent switch, which is used to apply and release the pressure on the sampler. A sample release device is included with each standard Discrete Interval Sampler.

Applications
Discrete interval sampling is ideal for obtaining truly representative groundwater samples from below floating product layers, or for obtaining samples of the product itself. The discrete interval sampler can also be used to profile open bodies of water and boreholes, and to collect samples from distinct levels or points of inflow. The Discrete Interval Sampler is a passive sampler that is pressurized when lowered and upon retrieval to prevent water from mixing at different levels. Designed to give zero purge samples.

Models
Solinst also offers the Model 425-D Deep Sampling Discrete Interval Sampler for obtaining samples from submerged depths as much as 1200m (4000 ft).
