Breaking Down the Features of Barnstead Demineralizer Bantam D0800

Specifications

The Barnstead Demineralizer Bantam D0800 is engineered for efficient demineralization. It connects directly to a raw water line, providing a continuous flow of demineralized water at atmospheric pressure. The unit features a direct reading meter that constantly displays water purity, calibrated in parts per million (ppm) as NaCl from 0-19, and in ohms resistance from 25,000 to 18,000,000 ohms-cm.

This meter is crucial as it not only indicates real-time purity but also signals when the demineralizing cartridge needs replacement, preventing accidental use of less-than-pure water. The flow rate is specified as 19-38 L/hour (5-10 gal./hour), which is ample for most laboratory applications. Its compact dimensions of 15.2W x 22.2D x 72.4H cm (6 x 8 ¾ x 28 ½ inches) make it suitable for benchtops or wall mounting, with a removable pedestal for added versatility.

The electrical specifications are standard for laboratory equipment, requiring 120V, 50/60 Hz. The Thermo Scientific No. for this model is D0800. The unit is sold as an each item, meaning a single complete demineralizer system. These specifications combined offer a practical, user-friendly system for achieving high-purity water without complex infrastructure.

Performance & Functionality

The primary function of the Barnstead Bantam D0800 is to deliver demineralized water, and it excels at this task. Its ability to connect directly to the raw water supply simplifies installation and immediate use. The continuous flow ensures that you can fill containers of various sizes without waiting for reservoirs to refill, which is a significant advantage in a busy lab.

The direct reading purity meter is perhaps its most valuable feature for performance monitoring. It provides instant feedback on water quality, eliminating guesswork and ensuring that experiments are not compromised by ionic contamination. This feature alone justifies its inclusion over simpler filtration methods.

A minor point for improvement could be the upper limit of the purity meter. While 18 million ohms-cm is excellent for many applications, some highly sensitive biochemical or trace-element analyses might require even higher resistivity. However, for the vast majority of standard laboratory demineralization needs, its performance is more than adequate.
