 Avalanche® Multi-bottle, Multi-function Sampler

Advanced sampling and data logging with transportable, dual-power cooling 

 

The Avalanche® Sampler is based on the industry-leading 6712 controller. Avalanche provides the advanced control, data logging, and communication features of the 6712, combined with on-the-go cooling from either AC power or a 12-volt deep cycle battery. Bottle configurations include 5 gallon and 2.5 gallon composite as well as 4 x 1 gallon and 14 x 950 ml sequential. 

Like the simpler, composite-only Glacier sampler, Avalanche delivers 48 hours or more of refrigeration from a 12 volt deep cycle battery. Its power-saving cooling system remains on standby until the first sample is drawn, and then switches on to preserve the collected samples until a convenient pickup time. You can easily enter complex programs to suit your unique needs. Available routines include: pause and resume for intermittent discharge flow monitoring; sampler pacing by time, non-uniform time, flow or external event; and random interval sample collection.

Standard Features

  • Standard and extended programming keeps setup simple when you don't need advanced features. 
  • NEMA 4x, 6 (IP67) controller enclosure is watertight and dustproof. 
  • SDI-12 interface provides “plug and play” connection with multi-parameter water-quality sondes and other compatible devices. 
  • Standard 512kB memory gives you great flexibility for logging environmental data. 
  • NEMA 4X, 6 (IP67) controller enclosure 
  • Sample delivery at the EPA-recommended velocity of 2 ft/sec., even at head heights of 26 feet. 
  • Patented pump revolution counter ensures accurate sample volumes - and tells you when tubing should be replaced.

Applications

  • Stormwater Runoff Compliance 
  • TMDL and Watershed monitoring 
  • Enforcement Monitoring 
  • Anywhere you need advanced sampling capability combined with data logging and communications for flow, rainfall, and water quality parameters – plus reliable, on-demand cooling.

Glacier® Composite Sampler

It’s a brand new kind of sampler! 

 

The Glacier® Sampler combines the small size, light weight, and mobility of a portable with an exclusive new active temperature control system. Its revolutionary design gives you the best of all worlds: easy transport, quick setup, and accurate sample preservation – without reliance on ice or utility power! An optional Mobility Kit with aluminum frame and pneumatic tires lets you wheel Glacier even over rough terrain to remote sampling sites 

In the field, Glacier delivers 48 hours or more of refrigeration from a 12 volt deep cycle battery. Its power-saving cooling system can be set to standby until the first sample is drawn. Glacier can wait patiently for days or weeks to collect event-triggered samples, and then preserve them until a convenient pickup time. For even greater versatility, Glacier also plugs into a 120 or 240VAC outlet to run on AC line voltage. 

Unique temperature control system 
Glacier’s new patent-pending temperature control system continuously measures the actual sample temperature, and precisely regulates cooling to ensure accurate sample preservation.

Standard Features

  • Dependable, easy-to-program controller uses field-proven technology to ensure the reliability, ease of operation, and durability you expect from Isco. 
  • Runs on either external 12VDC or 120/240VAC mains power. 
  • Recall and run a stored program with two keystrokes. 
  • NEMA 4x, 6 (IP67) controller enclosure is watertight and dustproof. 
  • Actual measured sample temperature is stored by controller. Min, max, and average temperature are reported on LCD and in downloadable file using Samplink software. 
  • Patented LD90 non-contacting Liquid Presence Detector and pump revolution counting system ensure accurate sample volumes. 
  • Collect composite samples in 10 or 20 liter bottles - or eliminate bottle washing with ProPak® single-use liners.

Applications

  • Stormwater sampling 
  • Biomonitoring – where accurate sample preservation is needed 
  • Influent and effluent sampling – Glacier can be easily moved in-plant to collect monthly or weekly at multiple sampling points. (Not recommended for use in corrosive atmospheres.) 
  • Anywhere you need sampling mobility plus reliable, ice-free cooling

Options and Accessories

  • Mobility Option – includes alumnimum frame with handle and pneumatic tires 
  • Single-bottle sampling configurations- 1 x 10 liter plastic or glass; 1 x 20 liter plastic, or 9-liter ProPak single use liner system 
  • Suction lines and strainers
