My Honest Thoughts on the Barnstead/thermolyne Easypure Ii Water Purification Systems, Thermo Scientific D50229
Water. It’s the lifeblood of any laboratory, crucial for everything from rinsing glassware to running sensitive experiments. But not just any water will do. That’s why I was intrigued by the Barnstead/thermolyne Easypure Ii Water Purification Systems, Thermo Scientific D50229.
For years, I’ve been battling inconsistent water quality in our research lab, leading to skewed results and frustrating delays. We needed a reliable solution to consistently produce Type I water, and after extensive research, the EASYpure II seemed like a promising contender. My initial interest stemmed from the system’s compact design and claims of producing water with a total organic carbon (TOC) content less than 10ppb.
Upon unboxing, the EASYpure II impressed me with its solid construction. The molded plastic front and metal back gave it a robust feel, hinting at durability. Its size was also a pleasant surprise; it’s compact enough to fit comfortably on a crowded lab bench. Compared to some bulkier water purification systems I’ve used in the past, this one felt refreshingly space-efficient.
I considered the MilliporeSigma Milli-Q system and the PURELAB flex from ELGA LabWater. Ultimately, the Barnstead/thermolyne EASYpure II won out due to its smaller footprint and seemingly simpler operation. My first impression was one of cautious optimism. I was excited about the potential for consistent, high-purity water, but also aware that the proof would be in the pudding, or rather, the purified water.
Real-World Testing: Putting Barnstead/thermolyne Easypure Ii Water Purification Systems, Thermo Scientific D50229 to the Test
First Use Experience
Our initial testing ground for the EASYpure II was our analytical chemistry lab. We rely on ultra-pure water for HPLC and mass spectrometry analyses. The system was connected to our existing pre-treated water supply (reverse osmosis). Getting the EASYpure II up and running was surprisingly straightforward.
The microprocessor-controlled purity monitor displayed resistivity readings almost instantly. Within minutes, we were dispensing water with a resistivity of 18.2 megohm-cm, very close to the theoretical maximum. We did notice a slight lag in flow rate initially, but it stabilized after a few flushes.
Extended Use & Reliability
After several weeks of continuous operation, the EASYpure II has proven remarkably reliable. We’ve consistently obtained Type I water suitable for even our most sensitive applications. The resistivity remains stable, and the system’s recirculation feature seems to effectively maintain purity during standby.
There have been no noticeable signs of wear and tear. The system requires minimal maintenance. Cartridge replacement is simple and infrequent, based on our usage volume. Compared to our old mixed-bed deionization system, the EASYpure II represents a significant improvement in both water quality and operational convenience.
