Barnstead/thermolyne E-pure Water Purification Systems, Thermo Scientific D5022 Review

Let’s Dive into Barnstead/thermolyne E-pure Water Purification Systems, Thermo Scientific D5022

The need for ultrapure water is paramount in many laboratory settings, where even trace contaminants can skew results or ruin experiments. The Barnstead/thermolyne E-pure Water Purification Systems, Thermo Scientific D5022 promises a reliable solution for producing Type I water, essential for sensitive analytical techniques and cell culture applications. This three-module system is designed to deliver high-quality, organic-free water, but does it live up to the hype?

My quest for this system began when our lab’s existing water purification setup started producing inconsistent results, causing havoc with our HPLC analyses. We needed a dependable system capable of consistently delivering Type I water, especially concerning organic contaminants that can interfere with our assays. The Thermo Scientific D5022 stood out due to its reputation and three-module design, which, theoretically, should provide a robust purification process.

Upon unboxing, the system felt solid and well-constructed. The polypropylene canisters inspire confidence, and the overall design appears geared toward easy maintenance. Compared to our previous system, which used proprietary cartridges, the Thermo Scientific D5022 seems more accessible in terms of replacement parts. My initial thought was excitement tinged with cautious optimism, hoping it would resolve our ongoing water quality issues.

Compared to a Millipore Direct-Q system and a Sartorius Arium Mini, the Barnstead/thermolyne E-pure Water Purification Systems, Thermo Scientific D5022 seemed to strike a balance between cost and promised performance. The Millipore system was significantly more expensive, while the Sartorius, although compact, didn’t seem as robust for handling our lab’s daily water needs. The choice hinged on the Thermo Scientific D5022’s combination of features and reputation.

Initially, I was cautiously excited. The promise of consistently pure, organic-free water was compelling, especially given the frustration we’d experienced with our previous system. The build quality seemed decent, but the true test would be its performance under pressure in our demanding laboratory environment.

Real-World Testing: Putting Barnstead/thermolyne E-pure Water Purification Systems, Thermo Scientific D5022 to the Test

First Use Experience

The Barnstead/thermolyne E-pure Water Purification Systems, Thermo Scientific D5022 was installed in our analytical chemistry lab and immediately put to use supplying water for HPLC, cell culture, and reagent preparation. The system was fed with pretreated water from our building’s central system. Initially, the setup was straightforward, with clear instructions guiding the cartridge installation and system priming.

Under normal lab conditions, with temperatures around 22°C and consistent feedwater quality, the Thermo Scientific D5022 performed admirably during the first week. The water produced met Type I standards, and our HPLC analyses showed a significant improvement in baseline stability, indicating reduced organic contamination. However, the flow rate seemed slightly lower than the advertised 2L/min, which became noticeable when filling larger containers.

The system was reasonably easy to use, requiring minimal training for our lab personnel. The digital resistivity meter provided clear readings, although it took a few uses to become comfortable interpreting the data and understanding when cartridge replacement might be necessary. There were no major surprises during the initial use, only the slightly lower flow rate than expected.

Extended Use & Reliability

After three months of continuous operation, the Barnstead/thermolyne E-pure Water Purification Systems, Thermo Scientific D5022 has proven to be a reliable workhorse. The water quality has remained consistently high, with no noticeable degradation in resistivity or increase in organic contaminants, confirmed by regular TOC measurements. The initial slightly slower flow rate remains consistent.

There are no significant signs of wear and tear. The polypropylene canisters still look new, and the connections remain leak-free. The only maintenance required has been periodic cleaning of the external surfaces and monitoring the cartridge life indicators.

Maintaining the system is simple. Barnstead’s design allows for easy cartridge replacement, a major plus compared to our previous system. Compared to our old system, the Thermo Scientific D5022 significantly outperforms it in water quality consistency and ease of maintenance, making it a worthwhile upgrade.
