Kimble/Kontes Tube Disp Flint 13X100 PK250 60CM13 Review

The Kimble/Kontes Tube Disp Flint 13X100 PK250 60CM13: Not Just Another Review

As a seasoned outdoor and tactical gear specialist, I’ve handled everything from advanced optics to rugged survival kits, but rarely do I get excited about something as seemingly simple as a test tube. The Kimble/Kontes Tube Disp Flint 13X100 PK250 60CM13, however, piqued my interest because of its potential applications in field testing and sample collection – areas where durability and reliability are paramount. These aren’t your average school science project tubes; these are designed for serious work in various laboratory and field settings.

My interest in these tubes stemmed from a need to reliably collect and transport water and soil samples during extended backcountry trips for preliminary analysis. I wanted a cost-effective and dependable solution for environmental assessments far from a conventional lab. The Kimble/Kontes tubes offered a potential solution that I needed to test.

Upon opening the package, I was immediately struck by the robust nature of the glass, described by VWR as Soda Lime (Flint) glass. The tubes felt significantly more substantial than the thinner, more fragile tubes I’d used in the past. My initial impression was one of cautious optimism; these felt like they could withstand the rigors of field use.

I considered similar products from Corning and Fisher Scientific, but the Kimble/Kontes tubes offered a better balance of price and reported durability based on available specifications. It seemed the best value for the sheer quantity provided (250 tubes). I was excited to put them to the test.

Real-World Testing: Putting Kimble/Kontes Tube Disp Flint 13X100 PK250 60CM13 to the Test

First Use Experience

My first real-world test involved a week-long backpacking trip into the Sierra Nevada mountains, focusing on water quality assessments of remote streams. I used the Kimble/Kontes Tube Disp Flint 13X100 PK250 60CM13 to collect water samples from different locations, ranging from high-altitude snowmelt streams to tannin-rich creek beds. The tubes were transported within a padded section of my pack to minimize the risk of breakage.

The tubes performed admirably in varying conditions. While the Sierra Nevada test did not involve extreme temperatures, the tubes were exposed to significant temperature fluctuations and moisture. Filling the tubes and securing them for transport was straightforward. There were no issues with leaks or breakage during this initial field test.

Extended Use & Reliability

After several months of regular use, the Kimble/Kontes Tube Disp Flint 13X100 PK250 60CM13 have proven to be remarkably durable. While I have broken a few due to accidental drops on hard surfaces, the overall breakage rate has been lower than expected, given the glass construction. The tubes have also held up well to repeated cleaning and sterilization.

I’ve used these tubes for everything from collecting soil samples for pH testing to holding small amounts of solvents for cleaning delicate optics in the field. The key has been diligent packing and handling. They’ve outperformed some plastic alternatives in terms of chemical resistance.

Maintaining these tubes is relatively simple. They are easily cleaned with standard laboratory detergents and can be autoclaved for sterilization. This is a significant advantage over some disposable plastic tubes, which cannot withstand high temperatures. I’ve found that proper cleaning and storage are key to maximizing their lifespan.

Breaking Down the Features of Kimble/Kontes Tube Disp Flint 13X100 PK250 60CM13

Specifications

• Description: TUBE DISP FLINT 13X100 PK250 – This clearly defines the product as disposable flint glass tubes packaged in a quantity of 250. The “disp” indicates their intended use as disposable items, minimizing cleaning concerns in certain applications.

• Material: Soda Lime (Flint) Glass – This type of glass offers a good balance of chemical resistance and cost-effectiveness. While not as chemically inert as borosilicate glass (Pyrex), it’s suitable for a wide range of applications, particularly in general chemistry and biological sample collection.

• Dimensions: 13×100 mm – These dimensions represent the outer diameter (13 mm) and length (100 mm) of each tube. This is a standard size, providing a reasonable volume for most sample collection and testing needs.

• Package Quantity: PK250 – The package contains 250 individual tubes, making it a cost-effective option for labs or field operations requiring a large number of disposable tubes.

These specifications are crucial because they dictate the tube’s suitability for specific applications. The flint glass construction makes them chemically sound for the majority of applications. The standard size ensures compatibility with common lab equipment.

Performance & Functionality

The Kimble/Kontes Tube Disp Flint 13X100 PK250 60CM13 perform their primary function admirably: holding and transporting liquids and solids for analysis. The glass is generally inert enough to not contaminate samples (though ultra-sensitive work might require borosilicate).

A key strength is their chemical resistance, allowing the storage of a wide range of substances without degradation of the tube itself. A minor weakness is their fragility compared to plastic alternatives; however, careful handling mitigates this issue. Overall, they meet and even exceed expectations, considering their intended use as disposable tubes.

Design & Ergonomics

The design is simple and functional. The tubes are lightweight and easy to handle, even with gloved hands. The round bottom design can make them unstable on flat surfaces without a rack.

There is minimal learning curve. They are simply tubes that can be filled and, typically, capped (caps are sold separately). The lack of graduated markings can be a slight inconvenience for precise measurements, but this is not their primary purpose.

Durability & Maintenance

While these are designed to be disposable, their robust flint glass construction gives them a reasonable lifespan if handled carefully. The key to longevity is preventing breakage from impacts.

Cleaning is straightforward. They can be cleaned with standard laboratory detergents and sterilized via autoclaving, allowing for repeated use in non-critical applications.

Accessories and Customization Options

These tubes don’t come with any specific accessories, such as caps or racks. These must be purchased separately.

Compatible accessories are widely available from various brands. Standard 13 mm tube caps fit perfectly, and a wide range of test tube racks can accommodate the 13×100 mm dimensions. The universal sizing makes them easily adaptable to different laboratory setups.

Pros and Cons of Kimble/Kontes Tube Disp Flint 13X100 PK250 60CM13

Who Should Buy Kimble/Kontes Tube Disp Flint 13X100 PK250 60CM13?

These tubes are perfect for researchers, field scientists, and anyone needing a cost-effective and reliable solution for collecting and storing samples. They are ideal for general chemistry labs, environmental testing, and basic biological sample collection.

These might not be the best choice for applications requiring ultra-high purity or extreme chemical resistance. Borosilicate glass tubes would be a better option in those instances.

Must-have accessories include 13 mm test tube caps to prevent leaks and contamination, as well as a test tube rack for secure storage and transport.
