A Close Look at the Barnstead MEGA-PURE Automatic Water Distillation Apparatus, Models MP-3A, MP-6A and MP-11A, Barnstead 740883 Accessories Immersion Heater For 240V Mega-Pure Stills
The Barnstead MEGA-PURE Automatic Water Distillation Apparatus represents a pinnacle in laboratory-grade water purification. Manufactured by Barnstead, this system, available in MP-3A, MP-6A, and MP-11A models, coupled with the 740883 Accessories Immersion Heater for 240V Mega-Pure Stills, promises unparalleled water purity for critical applications. This review will delve into my experiences with this system, its strengths, weaknesses, and whether it truly lives up to its promise of delivering ultra-pure water.
My journey to acquiring the Barnstead MEGA-PURE stemmed from a growing need for consistently high-quality water in our advanced materials research lab. We were facing inconsistent results in sensitive experiments. The problem was traced back to trace contaminants in our existing water source, even after using multiple filtration stages.
The unit arrived securely packaged, showcasing the Barnstead’s commitment to protecting its investment. Upon unboxing, I was immediately struck by the robust construction, featuring high-quality PYREX and VYCOR glass components. The epoxy-coated aluminum cabinet exuded durability, and the overall design felt meticulously engineered for long-term reliability.
Before settling on the MEGA-PURE, I considered a Millipore system and a reverse osmosis setup with deionization cartridges. The Millipore system was significantly more expensive. While the RO/DI setup had a lower upfront cost, the recurring expenses of replacing cartridges and the potential for inconsistent water quality made the MEGA-PURE, with its promise of consistent, single-distillation purity, the more attractive long-term solution.
My first impression was one of cautious optimism. The price tag is substantial, but if the Barnstead MEGA-PURE delivers on its promise of consistent, ultra-pure water, it would be a worthwhile investment.
Real-World Testing: Putting Barnstead MEGA-PURE Automatic Water Distillation Apparatus, Models MP-3A, MP-6A and MP-11A, Barnstead 740883 Accessories Immersion Heater For 240V Mega-Pure Stills to the Test
First Use Experience
The initial testing took place within our controlled laboratory environment, simulating the demands of our research. I carefully followed the setup instructions, connecting the system to our existing water supply and electrical mains, utilizing the 240V Immersion Heater. The MEGA-PURE was easy to start up.
During the initial run, the MEGA-PURE operated smoothly, albeit with a noticeable hum from the VYCOR immersion heater. The ambient temperature of the lab remained consistent at 22°C, and the system efficiently distilled water at the rate specified for the MP-6A model we were testing. The resulting water, tested with our lab’s resistivity meter, showed exceptional purity, exceeding the capabilities of our previous filtration system.
Extended Use & Reliability
After several months of continuous operation, the Barnstead MEGA-PURE has proven to be a reliable workhorse in our lab. The water quality has remained consistently high, eliminating the variability we previously experienced. The robust construction has held up well to the rigors of daily use.
Maintenance is straightforward, primarily involving periodic cleaning of the glass components and monitoring the immersion heater. A few times, I have noticed mineral scale buildup, which was easily addressed using a mild acid solution, as recommended by Barnstead. Compared to our previous RO/DI system, the MEGA-PURE requires significantly less hands-on maintenance and produces a much more consistent product.
