Kimble/Kontes Flask Screw Cap Scl 2000ML PK2 26505 2000 Review

The Kimble/Kontes Flask Screw Cap Scl 2000ML PK2 26505 2000: Is It Really That Good?

In the world of outdoor gear, we often focus on knives, tents, and packs. But the humble flask plays a crucial role in countless scenarios, from preparing solutions in a remote field lab to safely storing samples collected in the wild. The Kimble/Kontes Flask Screw Cap Scl 2000ML PK2 26505 2000 promises to deliver reliable performance in these demanding environments. This two-pack of 2-liter Erlenmeyer flasks from Kimble/Kontes features a screw cap and graduated scale, seemingly tailored for precision and secure storage.

My work often involves setting up temporary labs in the field, where I need reliable and sterile containers for mixing and storing reagents. I was seeking a flask that could handle a large volume, withstand transportation, and prevent contamination. I needed something more robust than your average lab beaker.

Upon unboxing, I was immediately impressed by the heft and clarity of the glass. These weren’t flimsy containers. The screw caps felt solid and the rubber liners appeared to provide a tight seal. The graduated scale seemed clear and accurate, a vital feature for my applications.

Compared to standard beakers or generic plastic containers, the Kimble/Kontes Flask Screw Cap Scl 2000ML PK2 26505 2000 offers superior volume, a secure screw-top closure, and a marked scale for precision. I considered using a large Pyrex beaker with a silicone stopper, but I was concerned about accidental spills and the lack of volume markings. The Kimble/Kontes flasks offered a dedicated, all-in-one solution. My initial impression was one of cautious optimism – they looked the part, but I needed to see how they performed under real-world conditions.


Real-World Testing: Putting Kimble/Kontes Flask Screw Cap Scl 2000ML PK2 26505 2000 to the Test

First Use Experience

My first real test was setting up a temporary water analysis station at a remote fishing camp. I used one of the Kimble/Kontes flasks to mix a buffer solution for pH testing, and the other to store collected water samples. The dusty environment tested the seal of the screw cap.

The flasks performed admirably, even when jostled around in the back of my off-road vehicle. The screw caps held tight, preventing any leaks, and the graduated scale made measuring ingredients quick and easy. I appreciated not having to worry about contamination or spills while concentrating on other tasks.

Extended Use & Reliability

After several weeks of use, including repeated washings and autoclaving, the Kimble/Kontes Flask Screw Cap Scl 2000ML PK2 26505 2000 has shown remarkable durability. There are no signs of cracks or etching on the glass, and the screw caps still provide a reliable seal. Cleaning has been straightforward, even after storing viscous liquids.

Compared to my previous experience with cheaper glassware, these flasks feel significantly more robust and reliable. I’ve had generic beakers crack after only a few autoclave cycles, but the Kimble/Kontes flasks show no signs of deterioration. They’ve clearly outperformed my expectations, justifying the higher price.

Breaking Down the Features of Kimble/Kontes Flask Screw Cap Scl 2000ML PK2 26505 2000

Specifications

  • Description: FLASK SCREW CAP SCL 2000ML PK2. This clarifies that you’re getting two 2000mL (2-liter) flasks with screw caps.
  • Material: KIMAX glass. KIMAX is a borosilicate glass known for its excellent chemical resistance and thermal shock resistance.
  • Thread Finish: G.P.I. 38-430. This is a standardized thread size, important if you want to replace the caps with alternatives.
  • Design: Erlenmeyer flask design conforms to ASTM Specification E1404, Type III requirements. Adherence to this specification ensures consistent dimensions and quality.
  • Features: Approximate volume scales. This allows for quick estimates of liquid volume, but isn’t a substitute for precision measurement.
  • Liner: Inert rubber liners cemented into screw caps. These liners create a leak-proof seal and prevent chemical reactions with the flask contents.

These specifications matter because they directly impact the flask’s reliability, durability, and ease of use in demanding field conditions. The KIMAX glass means I don’t have to worry about the flask shattering from temperature changes. The secure screw cap with the rubber liner prevents spills and contamination.

Performance & Functionality

The Kimble/Kontes Flask Screw Cap Scl 2000ML PK2 26505 2000 performs its job of mixing and storing liquids exceptionally well. The large volume is ideal for preparing solutions in bulk, and the screw cap ensures a secure and leak-proof seal. The graduated scale, while not precise enough for exacting measurements, is helpful for quick approximations.

A key strength is its robust construction, providing confidence that it can withstand the rigors of field use. A minor weakness is the approximate scale; for truly accurate measurements, one must still rely on calibrated glassware. Overall, it meets and even exceeds my expectations, providing a reliable and durable solution for storing and mixing liquids.

Design & Ergonomics

The Kimble/Kontes Flask Screw Cap Scl 2000ML PK2 26505 2000 features a classic Erlenmeyer flask design. This makes it easy to swirl liquids and prevent splashing. The weight is substantial, giving a sense of quality and durability, but it might be tiring to hold for extended periods when full.

The screw cap design is simple and effective, providing a secure grip. The flasks require no special skills to use. The only potential learning curve is understanding the limitations of the approximate volume scale.

Durability & Maintenance

The KIMAX borosilicate glass ensures that the Kimble/Kontes Flask Screw Cap Scl 2000ML PK2 26505 2000 is likely to last for years with proper care. The glass resists chemical attack and thermal shock, and the screw caps are designed to withstand repeated use.

The flasks are easy to clean with standard laboratory detergents and can be autoclaved for sterilization. Replacing the screw caps might be necessary after prolonged use, but these are readily available.

Accessories and Customization Options

The Kimble/Kontes Flask Screw Cap Scl 2000ML PK2 26505 2000 comes standard with screw caps featuring cemented-in inert rubber liners. Customization options are limited, but you could potentially replace the screw caps with other compatible caps with different materials.

While not a direct accessory, a hot plate stirrer is a valuable companion tool for efficiently mixing solutions in the flask. The standardized thread finish could allow for adapting various custom closures, depending on specific needs.
