Let’s Dive into Barnstead MEGA-PURE Automatic Water Distillation Apparatus, Models MP-3A, MP-6A and MP-11A, Barnstead A440518 MP-6A Mega-Pure Glass Still
The Barnstead MEGA-PURE Automatic Water Distillation Apparatus, Models MP-3A, MP-6A and MP-11A, Barnstead A440518 MP-6A Mega-Pure Glass Still represents the pinnacle of laboratory-grade water purification technology. Designed for single distillation, this apparatus promises consistent, high-purity water for demanding applications.
My journey to this specific piece of equipment began with the increasing need for ultra-pure water in our field lab, particularly for calibrating sensitive analytical instruments deployed in remote locations. We needed a reliable system that could consistently produce water free from ionic contaminants and organic compounds, something our existing deionization setup couldn’t guarantee.
The MEGA-PURE arrived meticulously packaged, showcasing the fragility of its PYREX and VYCOR glass components. The robust, epoxy-coated aluminum cabinet gave me an immediate sense of the durable protection Barnstead prioritized.
Compared to other distillation systems like the Corning Mega-Pure and the Thermo Scientific Barnstead Classic Still, the MEGA-PURE stood out due to its automatic features and high temperature cut-off switch, increasing ease of use and providing a crucial safety measure. I chose this particular model for its balance of capacity (6 liters) and electrical requirements that fit our field lab’s limited power infrastructure.
My first impression was a blend of excitement and slight trepidation given the price tag and the glass construction, but overall I was optimistic that the promise of consistent high-purity water would justify the investment. It looked like a serious piece of equipment meant to deliver serious results.
Real-World Testing: Putting Barnstead MEGA-PURE Automatic Water Distillation Apparatus, Models MP-3A, MP-6A and MP-11A, Barnstead A440518 MP-6A Mega-Pure Glass Still to the Test
First Use Experience
The initial testing ground for the MEGA-PURE was our primary field laboratory, located in a high-altitude desert environment with significant mineral content in the local water supply. I wanted to observe how the system handled very impure source water and its ease of setup.
The MEGA-PURE performed surprisingly well, reducing the total dissolved solids (TDS) from over 500 ppm in the source water to less than 1 ppm in the distilled product, even in the challenging desert environment. The automatic features were intuitive, making the system surprisingly easy to operate despite my initial concerns about its complexity.
My only initial issue was a minor leak from a cooling water connection, which was easily resolved with a Teflon tape adjustment. Beyond that small hiccup, the first use was successful and delivered water exceeding our purity requirements.
Extended Use & Reliability
After several months of consistent use, the Barnstead MEGA-PURE has become a cornerstone of our field lab’s operations. The VYCOR immersion heaters have proven robust, showing no signs of degradation despite constant use.
There’s been minimal wear and tear, aside from the expected minor accumulation of mineral deposits in the boiling chamber. Cleaning is straightforward; a simple citric acid flush effectively removes any buildup, ensuring consistent performance.
The MEGA-PURE has significantly outperformed our previous deionization system, delivering more consistent water quality and requiring less frequent maintenance. It has become an indispensable component of our field laboratory operations.

- Safety Features: The high temperature cut-off and automatic feed/cooling water shut-off provide critical protection against damage and hazards.
While the MEGA-PURE excels at producing high-purity water, its throughput is limited by its 6-liter capacity. The cost is also significant, making it a worthwhile investment only for applications where ultra-pure water is essential.
Design & Ergonomics
The MEGA-PURE’s design prioritizes both performance and safety:
- PYREX and VYCOR Construction: These inert materials ensure minimal contamination of the distilled water.
- Epoxy-Coated Aluminum Cabinet: Provides robust protection against physical damage and chemical exposure.
- Vertical Condenser Vent: This feature allows volatile gases to escape, further enhancing water purity.
The MEGA-PURE isn’t particularly compact, but its benchtop or wall-mountable design provides installation flexibility. The lighted push-button controls are intuitive, minimizing the learning curve.
Durability & Maintenance
The MEGA-PURE is built for long-term reliability with minimal maintenance:
- Durable Materials: The PYREX, VYCOR, and aluminum construction ensure resistance to corrosion and degradation.
- Simple Cleaning: Periodic citric acid flushes effectively remove mineral deposits.
With proper maintenance, the MEGA-PURE should provide years of reliable service. Replacing the VYCOR immersion heaters may be necessary over time, but this is a relatively straightforward procedure.
Accessories and Customization Options
The MEGA-PURE is primarily a self-contained system, but some accessories can enhance its functionality:
- Storage Bottles: A dedicated storage bottle is required to collect the distilled water.
- Pre-Filters: Installing a pre-filter on the incoming water line can extend the life of the system by removing sediment and other large particles.
The MEGA-PURE doesn’t offer extensive customization options, but its core functionality is well-suited to a wide range of laboratory applications.
