The Road Test: Kimble/Kontes KIMAX Nessler Color Comparison Tubes, Tall Form, APHA Standard, Kimble Chase 45315-50100

The Kimble/Kontes KIMAX Nessler Color Comparison Tubes, Tall Form, APHA Standard, Kimble Chase 45315-50100 are essential laboratory tools used for precise colorimetric analysis, specifically designed to meet the stringent APHA standards. Manufactured by Kimble Chase, these tall-form Nessler tubes are constructed from high-quality KIMAX borosilicate glass, known for its exceptional clarity and chemical resistance. This ensures accurate and repeatable results in water and wastewater testing, as well as other applications where subtle color differences are critical.

My work in remote water quality testing often demands portable yet precise analytical tools. I needed a set of color comparison tubes that were robust enough to withstand field conditions and accurate enough to provide reliable data on-site, replacing my reliance on bulky lab equipment and time-consuming sample transport. The promise of shadowless bottoms and consistent graduations drew me to the Kimble/Kontes KIMAX Nessler Color Comparison Tubes.

Upon unboxing, I was immediately impressed by the robust build and clarity of the KIMAX glass. The tubes felt substantial in hand, and the white ceramic enamel markings were crisp and easy to read. Compared to the cheaper plastic alternatives I’ve used, these tubes felt like a serious upgrade.

I considered cheaper, generic color comparison tubes from lesser-known brands, and even reusing old graduated cylinders. However, the criticality of accurate water quality data, especially in sensitive environments, made me prioritize Kimble/Kontes’ commitment to APHA standards and quality construction. I also looked at matched sets, but felt unmatched was sufficient for my preliminary testing.

My initial impression was one of cautious optimism. While the price point ($319.99) is significantly higher than basic glassware, the potential for improved accuracy and durability seemed worth the investment, especially in the long run.

Real-World Testing: Putting Kimble/Kontes KIMAX Nessler Color Comparison Tubes, Tall Form, APHA Standard, Kimble Chase 45315-50100 to the Test

First Use Experience

My first field test of the Kimble/Kontes KIMAX Nessler Color Comparison Tubes took place on a remote section of the Colorado River, where I was assessing water quality parameters for a conservation project. I used the tubes to perform colorimetric tests for nitrate and phosphate levels, comparing the samples against standard solutions. The shadowless bottoms indeed transmitted light evenly, making subtle color differences much easier to discern compared to my older tubes.

In moderately windy conditions, the tall, narrow design was surprisingly stable. While the glass is durable, I was still careful not to drop them, which highlights an unavoidable con of using glass in the field. The large graduation markings at both 50 and 100 mL were easy to read, even under varying sunlight conditions.

The first use was problem-free, instilling confidence in the product’s design and functionality. The improved clarity and even light transmission noticeably enhanced the accuracy of my color comparisons.

Extended Use & Reliability

After several months of regular use in diverse field locations, the Kimble/Kontes KIMAX Nessler Color Comparison Tubes have proven to be a reliable and durable addition to my testing kit. Minor scratches have appeared on the glass from transport and handling, but these haven’t affected the clarity or readability of the tubes. I transport them in a padded case.

Cleaning is straightforward; a simple wash with laboratory detergent and distilled water is sufficient to remove residue. The KIMAX glass shows no signs of chemical degradation, even after repeated exposure to various reagents. Compared to my previous experience with plastic tubes that often became stained or warped, the Kimble/Kontes tubes maintain their integrity remarkably well.

Breaking Down the Features of Kimble/Kontes KIMAX Nessler Color Comparison Tubes, Tall Form, APHA Standard, Kimble Chase 45315-50100

Specifications

The Kimble/Kontes KIMAX Nessler Color Comparison Tubes, Tall Form, APHA Standard, Kimble Chase 45315-50100 feature several key specifications:

• Type of Set: Unmatched – allows for flexibility in using individual tubes.
• Cap Stopper: No – provides a clear, unobstructed view of the sample column.
• Graduated at: 50 and 100 mL – offers versatility in sample volume measurement.
• Size: 24×375 mm – provides an optimal aspect ratio for accurate color comparison.
• Scale Length: 275–295 mm – ensures a long optical path for enhanced sensitivity.
• Kimble Chase No.: 45315-50100 – identifies the specific product model.

These specifications are crucial for accurate colorimetric analysis. The tall form and long scale length maximize the path length of light through the sample, enhancing the visibility of subtle color differences. The KIMAX glass ensures minimal interference with the light spectrum, while the absence of a cap stopper prevents any distortion of the color viewed through the tube.

Performance & Functionality

The Kimble/Kontes KIMAX Nessler Color Comparison Tubes excel in their primary function: facilitating accurate color comparisons. The shadowless bottoms and clear KIMAX glass provide an ideal environment for observing subtle color variations in liquids.

The tubes are easy to use; simply fill to the desired graduation mark and compare against a standard solution. While unmatched tubes may introduce slight variations, the consistent graduations and high-quality glass minimize any significant errors. The only improvement I can imagine would be offering these in a case specific for field use.

The tubes meet and, in some cases, exceed my expectations for field-based colorimetric analysis. The enhanced clarity and consistent light transmission provide a noticeable improvement in accuracy compared to lower-quality alternatives.

Design & Ergonomics

The Kimble/Kontes KIMAX Nessler Color Comparison Tubes are designed with functionality in mind. The tall, narrow shape is optimized for light transmission and ease of handling.

The build quality is excellent. The KIMAX glass is robust and chemically resistant, ensuring longevity. The tall, thin shape, however, makes these tubes susceptible to tipping, so care must be taken to secure them during testing.

The user-friendliness is high; there is no learning curve involved. The clear graduations and smooth glass surface make these tubes a pleasure to use.

Durability & Maintenance

With proper care, the Kimble/Kontes KIMAX Nessler Color Comparison Tubes should last for many years. The KIMAX glass is resistant to most common laboratory chemicals and can withstand repeated cleaning cycles.

Maintenance is simple. Routine washing with laboratory detergent and distilled water is sufficient to keep the tubes clean and free from residue. The glass can be autoclaved for sterilization purposes, but this is generally not necessary for routine colorimetric analysis.

Accessories and Customization Options

The Kimble/Kontes KIMAX Nessler Color Comparison Tubes do not come with any specific accessories, as they are designed for use with standard laboratory equipment. However, they are compatible with various accessories, such as:

• Test tube racks: Essential for holding and organizing multiple tubes.
• Color comparators: Devices that provide standardized light sources for more accurate color comparisons.
• Standard solutions: Used as reference points for colorimetric analysis.

There are no specific customization options available for the tubes themselves, but users can select different sizes or matched sets to suit their specific needs. A carrying case with foam cutouts for each tube would be a very welcome addition.
