The lab can be a stressful place as you’re constantly judged on the ability to produce consistent and repeatable results. Give yourself some peace of mind with a LabStrong™ Fi-Streem™ distillation system that:

• Consistently produces ASTM Type II pure water.
• Is reliable, simple to use and easy to clean.
• Has safe operation through multiple safety features.
• Will be highly efficient and economical.

Of all the water purification technologies available, distillation can remove a wider range of impurities than any other single form of water purification. The Fi-Streem™ stills remove contaminants such as inorganic ions, dissolved gases, organics, particles, bacteria and pyrogens and the result is high quality ASTM Type II pure water. The patented vapor trap is designed to eliminate all vapor borne droplets, ensuring no carry-over of impurities in the distillate water. Plus the glass components in the still stop the leaching of impurities.

There’ll be no down time searching for needed tubing during installation because your new Fi-Streem™ still will ship with all necessary tubing. The space saving design of the Fi-Streem still allows you the flexibility to place the still almost anywhere in your lab. Either place the still on the bench or use the included bracket to mount it to the wall.

Designed with dual feed capabilities, the Fi-Streem™ still can easily be directly connected to tap water or a pretreated source. To optimize performance and reduce scaling, we recommend pairing your Fi-Streem™ still with the LabStrong™ Cascade, a deionization type II water system that can be used as a pretreatment. Using the Cascade™ as a pretreatment can greatly decrease water consumption and reduce scale build up within the boiling chamber, creating nearly maintenance free operation. Did you know that connecting to a pretreat source can yield 1 liter of stilled water from 1.1 liters of pretreated water!

Operating the Fi-Streem still is a breeze. With the push of a single button, the still is operational. With the press of two buttons, you can put the still in the clean mode! The still can be conveniently turned off for extended periods of time and returned to operation without the need for sanitizing or replacing consumables. Not only does this feature save valuable time, but also resources.

Imagine how great it would be to run your still 24 hours and unattended. The Fi-Streem still is supplied with a float switch which shuts off the still automatically when the water storage reservoir is full, enabling safe and unattended operation. The 24-hour automatic control activates the still as required to maintain a full reservoir. The automatic control start/stop feature is enabled when the still is connected to the LabStrong™ 8 Liter Carboy (A1052LS) or LabStrong™ 20 Liter Carboy (B00123) via the float switch.

Safety is a top concern for us all and with multiple safety features on the Fi-Streem™ still you can rest assured that you’ll be able to safely operate and maintain the still.

• A thermistor and over temperature protection device in the boiler assembly offers double protection against low water conditions.
• The base of the still is designed to contain accidental leaks within the still.
• The totally enclosed still design assures operator safety from breakage and hot surfaces.

Quotes to provide preventive maintenance (PM) contracts or quotes to provide installation/startup of the complete system are available upon request.
