Kimble/Kontes Septa, PTFE/Silicone Rubber, Kimble 73818A 24, Case of 144 Review

The Real-Use Review: Kimble/Kontes Septa, PTFE/Silicone Rubber, Kimble 73818A 24, Case of 144

As an outdoor and tactical gear specialist, I’ve come across a wide array of products promising reliability and dependability. However, few laboratory consumables find their way into my world – until the need arose for incredibly reliable sample storage in extreme conditions. The Kimble/Kontes Septa, PTFE/Silicone Rubber, Kimble 73818A 24, Case of 144 stood out as a potential solution, piquing my interest due to Kimble/Kontes‘ reputation for quality and the critical nature of a secure seal in volatile environments.

My work often involves analyzing samples collected in remote locations, from arctic expeditions to desert surveys. These samples, ranging from soil and water to biological specimens, need to be preserved without contamination or leakage, often under harsh conditions. This led me to search for a septum that could guarantee sample integrity, and the Kimble/Kontes Septa, PTFE/Silicone Rubber, Kimble 73818A 24, Case of 144, with its promise of resisting coring and suitability for autosamplers using screw-thread vials, seemed like a perfect fit.

Upon receiving the case of 144 septa, my initial impression was positive. The packaging was straightforward, ensuring the septa were kept clean and protected. The combination of PTFE (Polytetrafluoroethylene) and silicone rubber felt robust and well-constructed. This suggested a high level of chemical resistance and resilience, qualities I desperately needed.

Compared to cheaper, generic septa I’ve used in the past, the Kimble/Kontes option immediately felt superior. The generic septa often crumbled after a few punctures, leading to leakage and sample loss. I’d also considered using pre-scored aluminum foil septa for easier needle penetration, but those are prone to tearing in rugged environments. I chose the Kimble/Kontes Septa, PTFE/Silicone Rubber, Kimble 73818A 24, Case of 144 for their balance of robust construction and reliable sealing capabilities.

My first impression was cautiously optimistic. The build quality and the Kimble/Kontes name instilled confidence, but the real test would be how they performed in the field under pressure. I hoped they would live up to their promise of maintaining sample integrity across a wide range of demanding conditions.

Real-World Testing: Putting Kimble/Kontes Septa, PTFE/Silicone Rubber, Kimble 73818A 24, Case of 144 to the Test

First Use Experience

My initial test involved using the Kimble/Kontes Septa, PTFE/Silicone Rubber, Kimble 73818A 24, Case of 144 during a water sampling expedition in the Alaskan backcountry. The vials containing the septa were exposed to freezing temperatures, moisture, and constant jostling within my pack. This environment presented an immediate challenge to their sealing capabilities.

The septa performed admirably in these conditions. Even after multiple punctures with a syringe for on-site testing, the seals remained tight, preventing any leakage or contamination. Their resistance to coring proved valuable, as I didn’t encounter any fragments obstructing the needle or compromising the sample. I was initially concerned about the PTFE layer becoming brittle in the cold, but it maintained its flexibility and integrity.

The septa were incredibly easy to use, fitting perfectly with the standard 24-400 GPI thread size vials used in the field. No special tools or techniques were needed for installation or needle penetration. One initial concern was the potential for the silicone to degrade upon contact with certain hydrocarbons, but the PTFE layer seemed to adequately protect the silicone layer, preventing any noticeable degradation after initial exposure.

Extended Use & Reliability

After several months of consistent use, the Kimble/Kontes Septa, PTFE/Silicone Rubber, Kimble 73818A 24, Case of 144 continue to impress. Even after repeated freeze-thaw cycles and exposure to a variety of chemicals, they maintain their sealing integrity. The durability is exceptional.

There are virtually no signs of wear and tear beyond the puncture marks from the needles, which are inevitable. Cleaning is straightforward, requiring only a wipe with a lint-free cloth and, if necessary, a mild solvent to remove any residue. The ease of maintenance is a significant advantage, especially in field conditions where time and resources are limited.

Compared to previous experiences with other septa, the Kimble/Kontes Septa, PTFE/Silicone Rubber, Kimble 73818A 24, Case of 144 outperform significantly. The consistent sealing and resistance to degradation provide peace of mind, knowing that the integrity of my samples is protected, even under the most demanding conditions. These septa offer a level of reliability that cheaper alternatives simply cannot match.
