Barnstead Remote Dispenser D11981 Review

The Real Deal Behind the Barnstead Remote Dispenser D11981

As a seasoned gear specialist with over a decade of hands-on experience across diverse environments, I’ve encountered my fair share of laboratory equipment. The Barnstead Remote Dispenser D11981 caught my eye not just for its functionality but for the promise of convenience it held for certain lab workflows. My lab’s reliance on purified water for critical experiments meant any efficiency boost was worth investigating. The need arose from a recurring bottleneck in our workflow: a technician having to repeatedly move to the main water purification unit to dispense small volumes of ultrapure water, a process that ate up valuable research time. This remote dispenser, from Barnstead, seemed like a direct solution to that problem.

Upon initial inspection, the dispenser presented itself as a robust, no-nonsense piece of equipment. The coiled tubing was neatly managed, and the connection points felt secure and well-engineered. There wasn’t anything flashy about its appearance, but that’s often a good sign in a lab setting where functionality trumps form. I had briefly considered looking into an additional, smaller-scale purification system for that specific workstation, but the cost and maintenance seemed prohibitive compared to a simple dispensing accessory. My first impression was one of practical utility – it looked like it would do exactly what it claimed.

First Use Experience

My first real-world test of this dispensing unit was on our primary research bench, where we conduct sensitive molecular biology assays. The setup involved connecting it to our existing Barnstead EASYpure* line feed system. Installation was straightforward, requiring minimal effort to secure the fittings.

The act of dispensing water for the first time felt remarkably smooth. The coiled tubing expanded just enough to reach the necessary working area without becoming unwieldy. There was no noticeable lag or sputtering; the water flow was consistent from the moment the dispense was initiated.

After a full week of daily use, dispensing water for cell culture media preparation and buffer dilutions, the dispenser continued to perform admirably. I deliberately subjected the coiled tubing to moderate bending and stretching as I moved around the bench, simulating real-world lab activity.

The durability seemed quite good; there were no signs of kinks or permanent deformation in the tubing. I also noticed that the unit’s design did an excellent job of minimizing residual water within the dispenser itself, a crucial factor in maintaining water purity. Cleaning was as simple as running a mild sanitizing solution through it periodically, which is standard practice for any water-contact equipment in my lab.

Compared to our old method of repeatedly walking to the main unit, this remote dispenser was a significant upgrade. It eliminated wasted steps and allowed for quicker experimental turnaround. The only minor quirk I encountered was the initial firmness of the coiled tubing, which straightened out with a bit of use.

Extended Use & Reliability

Over the subsequent months, the Barnstead Remote Dispenser D11981 became an indispensable part of our lab’s daily operations. It was used countless times a day, often by multiple technicians, for everything from rinsing glassware to filling reagent bottles.

The build quality held up exceptionally well. Despite the constant use, the tubing remained flexible, and the connections stayed tight, with no signs of leaks whatsoever. The dispensing nozzle consistently delivered a clean stream of water, and I never experienced any issues with contamination traced back to the dispenser itself.

Maintenance remained simple. A monthly flush with a dilute bleach solution, followed by thorough rinsing with purified water, was all that was needed to keep it in optimal condition. There were no complex parts to disassemble or special tools required, which was a welcome relief.

In comparison to some generic dispensing tubes I’ve seen used in other labs, this unit felt considerably more robust and reliable. Those often suffer from premature kinking or developing small leaks over time. The Barnstead model, however, feels built to withstand the rigors of a busy laboratory environment.

Specifications

The Barnstead Remote Dispenser D11981 is designed to seamlessly integrate with Barnstead EASYpure* and NANOpure* DIamond* water purification systems. Its primary specification is its ability to deliver ultrapure water up to 8 feet away from the main unit. This extended reach is facilitated by a coiled tube design, which is a key feature that allows for flexible positioning without creating a trip hazard or taking up excessive bench space.

The unique design of the dispenser is specifically engineered to virtually eliminate any dead volume. This is a critical technical detail for laboratory applications where water purity is paramount; dead volume can lead to stagnation and potential microbial growth or contamination. The coiled tubing itself is typically made of a durable, inert material suitable for ultrapure water applications, ensuring no leaching occurs.

While specific dimensions of the coiled tubing when unextended aren’t listed, the fact that it retracts to a compact form is a significant practical advantage. It means that when not in use, the dispenser doesn’t clutter the workstation. The “Each” unit designation implies it’s sold as a single dispensing assembly, ready for connection.

Performance & Functionality

The core function of the Barnstead Remote Dispenser D11981 is to provide convenient access to purified water at a distance from the main system, and it excels at this. Its performance is defined by its consistent, reliable water delivery. The flow rate, dictated by the connected purification system, is maintained without noticeable degradation through the dispenser.

A significant strength is its near-zero dead volume design. This is not just a marketing claim; in practice, it means that the water dispensed is as pure as it is at the outlet of the purification unit. This is crucial for sensitive experiments where even trace contamination can lead to erroneous results.

The primary area where it shines is its convenience and workflow enhancement. By allowing users to dispense water directly at their workstation, it drastically reduces the time and effort previously spent walking back and forth. This dramatically improves efficiency in tasks requiring frequent water replenishment.

Design & Ergonomics

The design of this remote dispenser prioritizes functionality and ease of use within a laboratory setting. The coiled tube is the most prominent design element, offering a practical solution for extending reach without a tangle of straight tubing. This design also contributes to a cleaner workspace, as excess tubing can retract neatly.

Ergonomically, the dispenser is straightforward. The dispensing nozzle is designed for easy activation, typically with a simple push or lever mechanism (though not explicitly detailed in the provided specs, this is standard for such devices). The overall feel is one of solid, dependable construction, as expected from a brand like Barnstead.

The materials appear to be chosen for their chemical resistance and compatibility with ultrapure water. While not visually striking, the utilitarian design is practical and fits seamlessly into the typical laboratory aesthetic. The minimal dead volume is an important functional design aspect that directly impacts purity and user confidence.

Durability & Maintenance

Based on my experience, the durability of the Barnstead Remote Dispenser D11981 is a key selling point. The components, particularly the tubing and connectors, are constructed from materials that resist degradation from repeated flexing and exposure to purified water. I haven’t encountered any signs of premature wear or performance degradation even after months of heavy use.

Maintenance is commendably simple. Regular flushing with appropriate sanitizing agents and purified water is sufficient to maintain its pristine condition. The absence of complex mechanical parts means fewer points of failure and less potential for wear and tear over time.

The coiled tubing is particularly resilient; it doesn’t easily kink or develop stress fractures, which are common failure points in less robust tubing. This inherent durability contributes to its long-term reliability and reduces the likelihood of unexpected downtime.

Accessories and Customization Options

The primary function of the Barnstead Remote Dispenser D11981 is its direct integration with existing Barnstead EASYpure* and NANOpure* DIamond* systems. As such, it doesn’t typically come with a wide array of external accessories in the way a multi-tool or tactical flashlight might. Its design is focused on being an add-on module rather than a standalone item requiring significant customization.

However, the critical “accessory” in its own right is the coiled tube itself, which is integral to its extended reach capability. Compatibility with specific Barnstead water purification models is the main consideration. Users should ensure their existing system is on the compatible list to ensure a proper, leak-free connection. There isn’t a need for user-added needles, tips, or other embellishments, as its purpose is direct dispensing of water.
