One Month Later: Barnstead Mega-pure Automatic Water Distillation Apparatus, Models Mp-3a, Mp-6a And Mp-11a, Thermo Scientific A440367 Review

The Barnstead Mega-pure Automatic Water Distillation Apparatus, Models Mp-3a, Mp-6a And Mp-11a, Thermo Scientific A440367 promises a consistent supply of high-purity water for laboratory use. This system, manufactured by Thermo Scientific, is designed for single distillation to improve source water quality. I was particularly drawn to its automated features and the use of inert materials to prevent contamination.

My work at a small biotech startup demanded a reliable source of ultra-pure water for sensitive experiments. We were previously relying on a mixed system of bottled water and a small deionizer, which proved inconsistent and time-consuming. The promise of consistent, high-quality water from the Barnstead Mega-pure was extremely appealing.

Unboxing the Mega-pure, the first thing that struck me was its substantial size. The epoxy-coated aluminum cabinet seemed robust, and the visible PYREX* and VYCOR* glassware gave it a scientific, professional look. The unit felt weighty, indicative of the quality components within.

I considered cheaper alternatives like the Corning Mega-Pure System MP-1 and the VWR Water Still, but their lower production volumes and less robust construction didn’t instill the same confidence. Ultimately, I chose the Barnstead Mega-pure for its reputation for reliability, higher production rate, and fully automated operation, despite the higher price. I was excited to finally have a dependable and consistent water source for our lab.

Real-World Testing: Putting Barnstead Mega-pure Automatic Water Distillation Apparatus, Models Mp-3a, Mp-6a And Mp-11a, Thermo Scientific A440367 to the Test

First Use Experience

I initially tested the Barnstead Mega-pure in our lab’s controlled environment, focusing on ease of setup and water quality. The ambient temperature was stable, and the water source was our municipal supply. Setup involved connecting the water and power, which was fairly straightforward.

The Mega-pure performed admirably, consistently producing distilled water within the specified purity range. I needed a brief period to familiarize myself with the panel-mounted controls. There were no unexpected issues, and the automatic shutdown feature functioned correctly when I simulated a low-water condition.

Extended Use & Reliability

After a month of continuous operation, the Barnstead Mega-pure has proven to be a reliable workhorse. The distilled water quality remains consistently high. There’s minimal wear and tear, although I’ve noticed some minor scaling in the boiling chamber, which is to be expected.

Cleaning the Mega-pure is relatively simple; a periodic rinse with a mild acid solution removes the scale effectively. Compared to our previous, inconsistent water sources, the Mega-pure has significantly improved our experiment success rate. It has exceeded my initial expectations.

Breaking Down the Features of Barnstead Mega-pure Automatic Water Distillation Apparatus, Models Mp-3a, Mp-6a And Mp-11a, Thermo Scientific A440367

Specifications

• Production Volume: The Barnstead Mega-pure comes in three models: MP-3A (3.4 L/hr), MP-6A (6.0 L/hr), and MP-11A (13 L/hr). This determines the amount of distilled water produced per hour.
• Cooling Water Capacity: MP-3A (30.3 L/hr), MP-6A (53 L/hr), and MP-11A (130 L/hr). Adequate cooling is crucial to efficient distillation.
• Dimensions: MP-3A & MP-6A (114.3H x 58.4W x 30.5D cm), MP-11A (136.6H x 73.7W x 35.6D cm). The unit requires a significant amount of bench or wall space.
• Operating Weight: MP-3A (38.6 kg), MP-6A (49.9 kg), and MP-11A (56.7 kg). The unit’s weight makes it essential to have a sturdy mounting location.
• Number of Heaters: MP-3A (1), MP-6A (2), and MP-11A (4). More heaters allow a faster and more consistent boiling process.
• Materials: Constructed of inert PYREX* and VYCOR* labware with fluoropolymer resin stopcock plugs. These materials are essential for preventing contamination of the distilled water.
• Heaters: VYCOR immersion heaters. VYCOR provides excellent resistance to thermal shock and chemical attack.
• Safety Features: Automatic shutdown if water level gets too low, high-temperature cut-off switch, and automatic feed/cooling water shutoff if power is lost. These features are designed to protect the apparatus and prevent hazards.
• Cabinet: Epoxy-coated aluminum cabinet. This provides durability and chemical resistance.
• Controls: Panel-mounted, lighted push-button controls. This makes the unit easy to operate and monitor.
• Listings: UL and CSA listed. This ensures the unit meets safety standards.

Performance & Functionality

The Barnstead Mega-pure performs its primary function, producing high-purity distilled water, exceedingly well. Its accuracy is excellent; the water consistently meets our stringent purity requirements. The automated features, like the level sensor and auto-shutoff, add greatly to its usability.

The biggest strength of the Mega-pure is its reliability. A potential weakness is the need for descaling, though this is manageable. The system far exceeds my expectations for consistent water quality.

Design & Ergonomics

The Barnstead Mega-pure’s build quality is exceptional. Its use of high-quality materials like PYREX* and VYCOR* ensures the purity of the distilled water. The panel-mounted controls are straightforward, but require some initial familiarization.

Durability & Maintenance

Given its robust construction and quality materials, the Barnstead Mega-pure should last for many years with proper maintenance. Maintaining the unit involves periodic descaling and inspection of the glassware. Parts are readily available, making repairs relatively straightforward.

Accessories and Customization Options

The Barnstead Mega-pure doesn’t come with many accessories, but it is designed to be integrated into a larger water purification system. A storage bottle is required but sold separately. The ability to connect to external storage and pre-treatment systems allows for some customization. This integration is a major benefit for labs with specific needs.
