Advantages of Our Portable Samplers

Unattended Operation – Set it and let it collect data for days or weeks
Consistent, Accurate Sampling – Meets regulatory requirements for repeatability
Easy Programming – Intuitive controls save setup time in the field
Compact, Durable Design – Built to withstand harsh environmental conditions
Flexible Power Options – Battery, AC, or solar-compatible for remote locations

How They Work

A portable water sampler uses a programmable controller and peristaltic pump to draw water from your source through an intake line into a sealed sample container. Depending on your needs, you can set:

Sample intervals – from minutes to hours between collections
Sample volume – ensuring consistent, repeatable measurements
Trigger events – based on time, flow, or external sensors
Container configurations – single or multiple bottles for composite or discrete samples

With rugged enclosures, battery-powered operation, and weather-resistant designs, these samplers perform reliably even in challenging field conditions.

Portable Models Available

We offer a full range of Teledyne ISCO portable samplers to suit your needs, including GLS, 6712, and BLZZRD series. Units can be purchased outright or rented for short-term projects, with quick delivery throughout California, Nevada, and Hawaii.

ISCO GLS Series

ISCO GLS Compact Composite Sampler

A truly portable solution, the GLS (Great Little Sampler) is light, compact, and field-ready.

Compact footprint – Only 16.5″ diameter, great for tight manholes (≥18″)
Lightweight – Weighs under 25 lb dry, easy to transport
Effortless setup – Two-button interface, programming takes under a minute
Reliable sampling – LD90 liquid sensor and pump RPM tracking ensure precise, repeatable results, even with line head changes
Versatile sample container – Options include 1 gal or 2.5 gal glass or poly bottles, otherwise a 2 gal ProPak bag; the insulated base accommodates ice for sample preservation

ISCO BLZZRD

The ISCO BLZZRD is a portable, refrigerated automatic water sampler designed for reliable sample preservation in the field. Its high-efficiency compressor system keeps collected samples at or below 4 °C, even in high ambient temperatures, meeting EPA preservation requirements. Built with a rugged, weather-resistant enclosure, the BLZZRD is ideal for stormwater, wastewater, and environmental monitoring where accurate, temperature-controlled composite or discrete samples are critical. The unit features programmable controls for time-, flow-, or event-based sampling, a powerful peristaltic pump with LD90 liquid detection for precision volume control, and flexible bottle configurations to suit project needs. Battery, AC, and solar power options make it adaptable for both short-term studies and long-term compliance monitoring in remote or urban locations.

ISCO Signature Portable Flowmeter

The ISCO Signature Portable Flowmeter is designed to work seamlessly with portable water samplers, providing precise open-channel flow measurement for rivers, streams, and wastewater channels. Its compact, portable design allows for quick deployment in the field, while ultrasonic and area-velocity sensing ensures accurate, real-time flow data under a wide range of conditions. By integrating directly with portable samplers, it enables flow-paced or event-triggered sampling, ensuring that collected water samples accurately reflect actual flow events. The flowmeter features intuitive software for on-site configuration and data logging, rugged waterproof housing for reliable operation in harsh environments, and flexible power options to support remote or extended deployments. This combination of portability, accuracy, and integration makes it ideal for environmental monitoring, stormwater compliance, and wastewater studies.
