ISCO 6712 Full Size Overview

The ISCO 6712 Full Size is part of the Teledyne ISCO 6700 Series portable sampler family. It is designed for demanding field sampling programs where capacity, flexibility, and integration options matter.

Compared with smaller compact samplers, the full-size 6712 is often selected when a site requires longer unattended deployments, larger sample storage capacity, more bottle configuration options, or more room for ice in the sampler base. It can be used for composite sampling, sequential sampling, flow-paced sampling, event-based sampling, and monitoring programs that rely on external sensors or triggering devices.

For stormwater, wastewater, and industrial monitoring teams, the ISCO 6712 offers a practical balance of field portability and advanced sampling control.

Key Benefits of the ISCO 6712

The ISCO 6712 is built for field programs that need more than basic grab sampling. It helps users automate collection, improve consistency, and reduce the need for repeated site visits.

Key benefits include:

  • Full-size portable sampler for demanding field sampling applications
  • Supports composite and sequential sample collection
  • Flexible bottle and sample container configurations
  • Programmable for time-paced, flow-paced, or event-triggered sampling
  • Compatible with flow meters, rain gauges, and monitoring modules
  • Suitable for manholes, stormwater sites, wastewater facilities, and remote monitoring locations
  • Battery, AC, and solar-compatible power options depending on site requirements
  • Available for purchase or rental with local support

How the ISCO 6712 Works

The ISCO 6712 uses a programmable controller and pump system to draw liquid through an intake line and deposit measured samples into one or more collection containers. Once installed at the sampling point, the sampler can collect samples automatically based on the program selected by the user.


Sampling programs may be based on time, flow, rainfall, level, or another external trigger. This makes the 6712 useful for both routine compliance sampling and event-based sampling programs, such as stormwater runoff monitoring during a rain event.


A typical setup includes the sampler, intake tubing, strainer, sample bottles or container, power source, and any required flow or trigger device. The exact configuration depends on the site, sampling objective, bottle requirements, and deployment duration.

Sampling Modes and Bottle Configurations

The ISCO 6712 can be configured for different sample collection strategies depending on your monitoring goals.

Composite Sampling

Composite sampling combines multiple sample draws into one container over a defined period or sampling event. This method is commonly used when the goal is to represent average conditions over time or across a flow event.

Composite sampling may be useful for wastewater compliance, industrial discharge monitoring, stormwater runoff studies, and process monitoring applications.

Sequential Sampling

Sequential sampling stores individual samples in separate bottles. This approach is useful when the timing of each sample matters, such as during a storm event, discharge event, process upset, or flow change.

By keeping samples separate, operators and analysts can better understand how water quality changes over time.

Multi-Bottle Configurations

The ISCO 6712 can support multiple bottle arrangements depending on the selected base, rack, bottle size, and sampling program. Multi-bottle setups are commonly used for discrete sampling, event tracking, and programs where separate sample intervals must be preserved.

Common configuration considerations include:

  • Required sample volume
  • Number of samples needed
  • Composite or discrete sampling method
  • Ice and preservation requirements
  • Deployment duration
  • Available space at the sampling location
  • Whether the sampler will be installed above grade, in a manhole, or in another field location

Common Applications

The ISCO 6712 is used across a wide range of water and wastewater monitoring programs.

✅ Stormwater Runoff Monitoring
The ISCO 6712 is well suited for collecting samples during rain events. When paired with the right trigger or monitoring equipment, it can help capture runoff samples when conditions change quickly and field staff may not be present.

✅ Wastewater Compliance Sampling

Municipal and industrial wastewater facilities use automatic samplers to support permit compliance, process monitoring, and discharge documentation. The 6712 can be configured for time-based or flow-paced sampling depending on the requirements of the monitoring program.


✅ Industrial Pretreatment Sampling

For industrial facilities and pretreatment programs, the ISCO 6712 can help document discharge characteristics and collect representative samples during production, washdown, or other process-related events.


✅ Environmental Field Studies
The 6712 can support watershed studies, stream monitoring, construction site monitoring, agricultural runoff studies, and other field programs where unattended sample collection is required.


✅ Collection System Monitoring
Portable samplers are often used in manholes, lift station areas, and collection system monitoring points. The 6712 can be configured with accessories such as a suspension harness, intake tubing, strainers, batteries, and flow modules to match the site conditions.

Integration and Monitoring Options

The ISCO 6712 can be used as a standalone automatic sampler or integrated with monitoring devices for more advanced sampling control.


Depending on the application, a 6712 setup may include:

  • Flow meters for flow-paced sampling
  • Rain gauges for storm-event sampling
  • pH and temperature modules
  • Submerged probe modules
  • Bubbler flow modules
  • Area velocity sensors
  • Analog input modules
  • Data retrieval accessories
  • AC, battery, or solar-compatible power options
  • Intake tubing, strainers, and replacement pump tubing


These options allow the sampler to be matched to the hydraulic conditions, sample collection goals, and reporting needs of the site.

Accessories for the ISCO 6712

Collection Bottles

Collection bottles are selected based on the required sample volume, sample count, laboratory requirements, and whether the program calls for composite or sequential sampling.

Bottle Racks

Bottle racks organize and position bottles inside the sampler base for multi-bottle sampling programs. The correct rack depends on the bottle count and bottle size required.

Pump Tubing

Pump tubing is a routine maintenance item for portable samplers. Replacing worn tubing helps maintain reliable sample collection and consistent pump performance.

Suction Line and Strainers

The suction line carries the sample from the source to the sampler. Strainers help keep larger debris from entering the intake line while allowing liquid to be collected from the monitoring point.

Batteries & Power Options

Portable sampler deployments may use battery power, AC power, or solar-compatible charging depending on the location and duration of the project.

Rain Gauge

A rain gauge can be used to support storm-event sampling programs where sample collection needs to begin based on rainfall.

Flow Modules

Flow modules and compatible flow monitoring equipment can be used to trigger or pace sample collection based on flow conditions.

Suspension Harness

A suspension harness can help lower and retrieve the sampler in manhole or confined access locations where proper support and positioning are needed.

Replacement Parts

Replacement parts such as tubing, bottles, strainers, batteries, and accessories help keep sampling programs running with less downtime.

Buy or Rent an ISCO 6712

The ISCO 6712 is available for both purchase and rental.

Renting may be the right choice for short-term monitoring projects, temporary compliance needs, stormwater studies, pilot programs, or emergency sampling. Purchasing may make more sense for recurring compliance programs, long-term monitoring, facility sampling, or teams that regularly deploy automatic samplers.
