Let’s Dive into Barnstead/thermolyne Easypure Ii Water Purification Systems, Thermo Scientific D50229
The Barnstead/thermolyne Easypure Ii Water Purification Systems, Thermo Scientific D50229 promises a compact solution for producing high-purity Type I water in laboratories. This system aims to deliver water with minimal organic carbon, catering to applications demanding stringent purity levels. Thermo Scientific, a well-known name in lab equipment, stands behind this product.
My quest for a reliable water purification system stemmed from increasingly stringent demands in our environmental testing lab. We needed a consistent source of ultrapure water for trace metal analysis, and our old system was no longer cutting it. The lure of <10ppb TOC (Total Organic Carbon) and the compact design drew me to the Easypure II.
The unit arrived well-packaged, a sign of Thermo Scientific’s attention to detail. Lifting it onto the bench, its solid construction was immediately apparent. The molded plastic front and metal back exuded quality, and the footprint was indeed smaller than I anticipated.
Compared to the Millipore Milli-Q system and the Elga PURELAB Classic, the Easypure II seemed a more budget-friendly option initially. However, the Easypure II boasted a recirculating standby mode, a feature I found appealing for maintaining water quality during periods of low usage, unlike some competing systems. I was cautiously optimistic about the system’s potential.
Real-World Testing: Putting Barnstead/thermolyne Easypure Ii Water Purification Systems, Thermo Scientific D50229 to the Test
First Use Experience
I set up the Easypure II system in our trace metal analysis lab, connecting it to our existing pre-treated RO water source. The initial setup was straightforward, with clear instructions provided. The system sprang to life with a quiet hum, and the digital resistivity reading on the purity monitor immediately caught my eye.
During the first week, we used the purified water for preparing blanks and standards for ICP-MS analysis. We noticed a significant reduction in background noise compared to our previous system. The water purity consistently met the <10ppb TOC specification, providing us confidence in our analytical results.
There were no major issues during the first week, although I did notice the flow rate was somewhat lower than expected (around 1 L/min with our line-fed model). This required some adjustment in our workflow, but the water quality was undeniable.
Extended Use & Reliability
After six months of continuous operation, the Easypure II has proven to be a reliable workhorse in the lab. The system maintains consistent water purity, with resistivity readings consistently at or near 18.2 megohm-cm.
The only visible wear and tear so far is some minor discoloration on the dispensing nozzle, but this doesn’t affect performance. The cartridges, however, require replacement every 3-4 months, depending on water usage and feedwater quality. Changing cartridges is relatively simple.
Compared to my previous system, the Easypure II is noticeably quieter and more energy-efficient. The recirculating standby mode also appears to be effective in maintaining water quality during downtime, which I appreciate. Overall, the Easypure II has exceeded my initial expectations.
Breaking Down the Features of Barnstead/thermolyne Easypure Ii Water Purification Systems, Thermo Scientific D50229
Specifications
The Barnstead/thermolyne Easypure Ii Water Purification Systems, Thermo Scientific D50229 features a microprocessor-controlled purity monitor, displaying digital resistivity readings with temperature compensation to 25°C. The system includes a 0.2µm filter at the outlet for removing particles and bacteria. It is available in both batch-fed (with a 7L reservoir) and line-fed models.
The line-fed models can deliver up to 1.5L/min flow rate, while batch-fed models offer 0.5L/min. All models are designed to produce Type I water with a TOC content of less than 10ppb. UV models further reduce TOC to below 3ppb using dual-wavelength ultraviolet light (185 and 254nm). UF models utilize a 10,000 molecular weight ultrafilter for low pyrogen levels (<0.005EU/mL).
These specifications are critical for applications requiring high purity water. The resistivity measurement ensures the absence of ionic contaminants, while the TOC level reflects the presence of organic impurities. The final 0.2µm filter is essential for removing bacteria, guaranteeing sterile water.
Performance & Functionality
The Easypure II excels at producing Type I water with a TOC content consistently below 10ppb. The resistivity readings are accurate and temperature-compensated, providing reliable feedback on water quality.
The system’s key strengths lie in its compact design and user-friendly operation. The flow rate, while not the fastest, is adequate for most lab applications. However, the need for frequent cartridge replacements can be seen as a weakness.
Overall, the Easypure II meets and even exceeds expectations for producing high-purity water. Its performance justifies its intended use in demanding laboratory environments.
Design & Ergonomics
The Easypure II boasts a durable cabinet with a metal back and a molded plastic front, ensuring longevity. The compact design allows for easy bench mounting, saving valuable lab space.
The system is designed to be user-friendly, with intuitive controls and a clear digital display. The cartridge replacement process is straightforward and requires no special tools.
Durability & Maintenance
The Easypure II is built to withstand the rigors of daily lab use. Its robust construction and quality components ensure a long service life.
Maintenance is limited to replacing cartridges and the final filter, both of which are easily accessible. With proper maintenance, the system should provide reliable operation for many years.
Accessories and Customization Options
The Easypure II system comes with a standard 0.2µm final filter. Additional accessories include various cartridges tailored for specific feedwater types and purity requirements.
The system is compatible with optional accessories such as a remote dispenser, allowing for convenient water access at different locations in the lab. Thermo Scientific also offers a range of pre-treatment systems to optimize feedwater quality.
