Compared to previous generic cartridges I’ve used in other systems, these Barnstead cartridges offer a noticeably longer service life and more stable output.

Breaking Down the Features of Barnstead Cartridge Kit No Filter Hplc D4802

Specifications

The Barnstead Cartridge Kit No Filter Hplc D4802 is a comprehensive replacement kit designed for specific Barnstead NANOpure water purification units, particularly the quad-style models. It includes several key cartridges that work in concert to produce extremely pure Type I water. The kit is explicitly described as a “Low organic, Type I Cartridge Kit without final filter,” meaning it focuses on removing ionic impurities and larger organic molecules, leaving the final polishing step for a separate filter. This distinction is vital for users who may have specific requirements for their final water quality or who prefer to select their final micron filter independently.

The kit contains a series of cartridges: D0836, D0803, D5027, and D5021. While the specific function of each cartridge isn’t detailed in the provided description, in the context of Type I water purification, these typically include stages for pre-filtration, ion exchange, and activated carbon adsorption. The absence of a final 0.2-micron filter means that this kit handles the bulk of the purification, and users must order a 0.2-micron filter separately, depending on the style of their remote dispenser. This modular approach allows for customization based on end-use applications and dispenser configurations.

Performance & Functionality

The primary function of the Barnstead Cartridge Kit No Filter Hplc D4802 is to deliver consistently high-purity Type I water. In my laboratory, this translates to water with an resistivity of 18.2 MΩ·cm and very low TOC levels. The kit excels at its main job, providing water that is free from dissolved ions and organic contaminants, which are critical for preventing baseline drift and ghost peaks in HPLC analysis.

The major strength of this kit is its effectiveness in achieving and maintaining stringent water purity standards essential for analytical science. Its performance directly contributes to the reliability and accuracy of sensitive experiments. A minor weakness, if one can call it that, is the requirement to source the final 0.2-micron filter separately, which adds an extra step to the purchasing process. However, this also offers flexibility for users to choose a filter that precisely matches their application’s needs or dispenser type.

Design & Ergonomics

The design of the Barnstead Cartridge Kit No Filter Hplc D4802 focuses on practical, efficient replacement within the Barnstead NANOpure system.
