Solinst 425-D Deep Sampling Discrete Interval Sampler
There is a great range of no-purge, or grab samplers, in HydroTerra’s marketplace. But one question we are constantly working to answer with our clients is: “Which grab sampler is the best one for my project?”
Solinst not only manufactures a great range of samplers for use in different situations, but they also provide great resources to help answer this very question. What’s clear is that one of the key considerations when selecting a grab sampler is the sampling depth:
- 428 BioBailer: 7.5m – 30m depth
- 429 Point Source Bailer: 7.5m – 60m depth
- 425 Discrete Interval Sampler: 7.5m – 90 m depth
- 425-D Deep Sampling Discrete Interval Sampler: 50m – 1200m depth
There are many more considerations of course, and we are pleased to share Solinst’s in-depth comparison of the different variations of grab samplers and when they are best used.
