Let’s Dive into Barnstead PURA-LITE Ind 50K OHM-CM 120V E3450
The Barnstead PURA-LITE Ind 50K OHM-CM 120V E3450 from Thermo Scientific (formerly Barnstead) is an economical water purity indicator designed for use with B-Pure deionizer cartridge systems. It’s a simple, yet crucial device for anyone relying on consistently high-purity water for critical applications. This indicator uses easy-to-read lights, a green one signifying acceptable water purity, and a red one warning of unacceptable levels.
My need for this device stemmed from a growing frustration in our small research lab. We were experiencing inconsistent results in our experiments, and after a thorough investigation, the culprit turned out to be fluctuating water purity from our aging deionization system. I needed a reliable, real-time indicator that wouldn’t break the bank, and that’s what led me to research Barnstead products.
Unboxing the PURA-LITE, I was immediately struck by its simplicity. It’s a no-frills device, encased in a durable plastic housing with a clear and straightforward indicator light display. The build quality felt robust, reassuring me that it could withstand the demands of a lab environment, though the plastic housing does feel less substantial than some higher-end models.
I considered other water purity indicators, including more complex digital models with conductivity readouts, such as the Myron L Ultrameter II. However, the PURA-LITE’s simplicity and clear visual indication of water quality appealed to me, as did its significantly lower price point compared to the Myron L. Another option was a basic handheld TDS (Total Dissolved Solids) meter, but those require manual testing and interpretation, lacking the real-time monitoring of the PURA-LITE. Ultimately, the combination of affordability, real-time monitoring, and ease of use made the Barnstead PURA-LITE Ind 50K OHM-CM 120V E3450 the clear winner.
My first impression was one of cautious optimism. I appreciated the straightforward design and the promise of real-time monitoring, but I was also slightly concerned about the long-term accuracy and reliability of a device relying on a simple indicator light. I hoped it would prove to be a valuable asset in maintaining the integrity of our research.
Real-World Testing: Putting Barnstead PURA-LITE Ind 50K OHM-CM 120V E3450 to the Test
First Use Experience
The initial setup was incredibly easy. The PURA-LITE simply threads into the outflow of our B-Pure deionizer cartridge system using its 12.7mm (1/2“) NPTM cell thread. I plugged it into a standard 120V outlet, and it sprang to life, displaying a reassuring green light. I tested the water immediately using a separate, calibrated conductivity meter, and the reading aligned perfectly with the PURA-LITE’s 50K OHM-CM threshold.
I observed the PURA-LITE during several experimental runs. The indicator light remained consistently green, confirming stable water purity. It provided peace of mind, allowing us to focus on our experiments without constantly second-guessing the water quality. No issues arose during this initial testing period, confirming the device was working exactly as described.
Extended Use & Reliability
After several months of continuous use, the PURA-LITE continues to perform admirably. The indicator light responds quickly to changes in water purity, turning red within minutes when the deionizer cartridge reaches its capacity. The visual indication has been invaluable, alerting us to the need for cartridge replacement before any potential contamination can affect our results.
There are no significant signs of wear and tear. The plastic housing has proven surprisingly durable, resisting minor bumps and splashes without any cracking or discoloration. Cleaning is a breeze; a simple wipe-down with a damp cloth is all it takes to keep it looking like new.
Compared to our previous method of infrequent manual water quality checks, the PURA-LITE is a game-changer. It provides continuous, reliable monitoring, ensuring consistent water purity and preventing costly experimental errors. It far outperforms the old manual testing methods, saving time and resources, and providing better overall confidence in our work.
Breaking Down the Features of Barnstead PURA-LITE Ind 50K OHM-CM 120V E3450
Specifications
The Barnstead PURA-LITE Ind 50K OHM-CM 120V E3450 has key specifications that directly impact its usability and performance:
- Resistivity: 50,000 ohms-cm. This indicates the threshold for acceptable water purity. When the water resistivity drops below this level, the indicator light turns red, alerting the user to a decline in water quality.
- Electrical: 120V. The PURA-LITE operates on standard 120V power, making it compatible with most laboratory and industrial settings.
- Thermo Scientific No.: E3450. This is the product’s unique identifier, facilitating easy ordering and referencing.
