My Experience with the Kimble/Kontes Natelson Capillary Tubes, Kimble Chase 603 Heparinized, Red Color Code: Here’s the Truth
The Kimble/Kontes Natelson Capillary Tubes, Kimble Chase 603 Heparinized, Red Color Code are essential tools in the field, especially when dealing with potential injuries or illnesses requiring rapid blood sample collection. These tubes, manufactured by Kimble Chase, are designed for easy and efficient collection of micro blood samples, especially useful in remote locations or emergency situations where larger blood draws are impractical. Their heparinized coating prevents clotting, ensuring sample integrity, and the red color code helps quickly identify them.
My journey to these capillary tubes started with a recurring challenge: the need for immediate blood samples in remote first aid scenarios. I was a medic for a wilderness search and rescue team, frequently facing situations where traditional venipuncture was not feasible or time-efficient. The need for quick and accurate blood collection was paramount. I needed a solution that was lightweight, reliable, and capable of preserving the sample until it could reach a lab.
Upon unboxing, my initial impression was one of simplicity and functionality. The Kimble/Kontes Natelson Capillary Tubes are neatly packed in lint-free boxes, which is crucial for maintaining their cleanliness and preventing contamination. The glass construction felt sturdy enough for field use, though obviously required careful handling to avoid breakage. The red color code was immediately noticeable and a welcome visual aid.
I considered a few alternatives before settling on these Kimble Chase tubes. I looked at some plastic micro-collection devices, but I was concerned about potential interference with certain assays and their overall durability in extreme temperatures. I had also considered using standard non-heparinized capillary tubes, but the risk of clotting, especially in warmer climates, made them unsuitable for my needs. Ultimately, the proven track record and heparinized coating of the Kimble/Kontes Natelson Capillary Tubes made them the clear winner.
My first impression was positive; they appeared to be a well-designed solution for on-the-spot blood collection. I was particularly impressed with the tapered tips, which promised easy and less traumatic blood collection.
Real-World Testing: Putting Kimble/Kontes Natelson Capillary Tubes, Kimble Chase 603 Heparinized, Red Color Code to the Test
First Use Experience
My initial field test took place during a search and rescue exercise in the high desert. The dry, dusty environment presented a challenge to maintaining sample integrity. I used the Kimble/Kontes Natelson Capillary Tubes to collect a small blood sample from a simulated casualty with a potential head injury.
The tapered tips made the collection process remarkably easy and relatively painless. I found that applying gentle pressure to the puncture site encouraged capillary action without causing undue discomfort. The heparinized coating proved its worth by preventing clotting even after a slight delay in sealing the tube due to the challenging environment.
There were no immediate issues, but I did notice the importance of using a proper capillary tube sealer to prevent leakage during transport. Sealing the tubes properly is of utmost importance.
Extended Use & Reliability
After several weeks of use in various field exercises and mock disaster scenarios, the Kimble/Kontes Natelson Capillary Tubes have proven to be reliable and durable. The glass construction, while requiring careful handling, has held up well to the rigors of being packed and transported in a medical kit. Minimal breakage was observed.
Cleaning is straightforward; any residual blood can be easily rinsed out with saline solution before being properly disposed of as biohazardous waste. Their compact design also allows for easy storage within medical kits. The heparin coating remained effective even after multiple uses from the same box.
These tubes have consistently outperformed my previous attempts at using alternative blood collection methods in the field. The ability to quickly and reliably obtain a small blood sample has proven invaluable in scenarios where time is of the essence.
