ASTM Type II Water Distillation Systems for Labs Fi-Streem™

The Fi-Streem™ stills consistently produce high-quality pure, type II water for labs needing a budget-friendly solution.

The stills can remove inorganic ions, dissolved gases, organics, particles, bacteria and pyrogens from water. These systems feature a unique, patented vapor trap designed to eliminate all vapor borne droplets, ensuring there is no carry-over of impurities in the distillate water. The result is consistently pyrogen-free water at your disposal.

The Fi-Streem™ stills require no pretesting or prequalification of water prior to installing. The stills can simply be connected to tap water and ready to operate. For convenience, each still is designed with dual feed capabilities for tap or pretreated feedwater. All of the necessary tubing is included with the still to complete installation. Designed to save space, the stills can be placed on a bench or mounted to a wall with the included wall mount bracket.

All LabStrong™ Fi-Streem™ Stills include the following items FREE so that your ordering and installation will be simple and easy.​


With the press of a single button, the still is operational. With the press of two buttons, the still can begin a self-cleaning operation. The built-in, fully automatic microprocessor controls simplify operation and cleaning while assuring high reliability.


Descaling of the still is simplified by a cleaning process that does not require the dismantling of any glassware. The process requires little time and is easy to complete. The microprocessor and thermistor controlled operation incorporates a dual flush program to ensure the still is ready to return to normal operation following the cleaning cycle.

The Fi-Streem™ stills keep your tanks and carboys full and ready on demand. The still is supplied with a float switch which automatically shuts off the still when the water storage reservoir is full, allowing for safe, 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 20 Liter Carboy (B00122), LabStrong 50 Liter Carboy (A1058LS), or LabStrong 40 Liter Storage Tank (B00121) via the float switch.

Safety is a priority and the Fi-Streem™ stills have multiple safety features to protect the still and the user. For instance, a thermistor and over-temperature protection device located in the boiler assembly offers double protection against low water conditions. Additionally, the base of the still is designed to contain accidental leaks within the still. Plus, the still’s design is fully enclosed, which ensures operator safety from breakage and hot surfaces.

Reducing energy is important and the Fi-Streem™ Stills are highly efficient. The optimal power design increases output with fewer watts and a built-in flow controller maximizes product water output while minimizing inlet water usage to drain. 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 important resources.

Optimize your still’s performance by pairing it with the LabStrong™ Cascade™ Type II Water Purification System.  Using the Cascade™ as a pretreat to the Fi-Streem™ still will reduce scale build up within the boiling chamber, creating nearly maintenance free operation. Click the button below to learn more about the LabStrong™ Cascade™ Type II Water Purification System.

Simple to install, operate and maintain

The Fi-Streem™ stills don’t require pretesting or prequalification of water prior to installing.  The still can simply be connected to a tap or pretreated water source to be operational.  Fi-Streem™ stills are designed with dual feed capabilities for tap and pretreated water.  All the necessary tubing is included with the still to complete installaion.

Operation of the unit is a breeze.  With the press of a single button, the still is operational.  With press of two buttons the still will be in a cleaning mode.

For further assistance, LabStrong™ has developed a video library that demonstrates installation, operation and maintenance of the unit. Just a few of the topics available include:

Pure water, also known as reagent grade type II water, plays a key role in the various laboratory functions. In the purification process, impurities such as ions, organics, endotoxins, and bacteria are removed. There are various purification methods to produce pure water from deionization, distillation, reverse osmosis (RO) or electrical ion exchange (EDI)—however, of all the water purification technologies available, distillation can remove a wider range of impurities than any other single form of water purification.

Distilled, type II water can be used as pretreat to an ultrapure, type I, water system or for general laboratory functions:
