Ease of use was exceptionally high. The tubing’s inherent pliability, combined with its precisely manufactured dimensions, meant I could manipulate it with one hand while securing connections with the other. There was no “fight” from the material; it simply bent and conformed as needed. This significantly sped up the setup process compared to some of the stiffer, more recalcitrant tubing I’ve encountered.

The only minor surprise after this initial use was how little “memory” the tubing had. It coiled back to its original shape with minimal effort after being uncoiled, which is excellent for storage and reuse. This indicated a very stable polymer structure, which is a testament to the platinum-curing process.

Extended Use & Reliability

Over the subsequent months, the Nalge Nunc 50 Platinum-Cured Silicone Tubing, NALGENE 8060-0190, Case became an indispensable part of my mobile laboratory setup. It has been used for transferring everything from delicate protein solutions and cell cultures to more aggressive buffers and sterilization agents. The tubing has also been subjected to repeated autoclaving cycles at 121°C (250°F) as part of our sterilization protocols.

After weeks of continuous use and multiple sterilization cycles, the tubing still exhibits no visible signs of degradation. There are no cracks, no hardening, and crucially, no discoloration or odor. Its remarkable resilience to repeated autoclaving is a testament to its material composition and the robustness of the platinum-curing process.

Maintenance and care have been incredibly straightforward. A simple rinse with distilled water or a mild detergent, followed by thorough rinsing and air drying, is all that’s typically required. The smooth, non-porous inner surface resists the adhesion of biological materials and residual chemicals, making cleaning remarkably efficient.

When comparing this to my previous experiences, the Nalge Nunc tubing stands head and shoulders above. I’ve previously used generic silicone tubing that would become brittle after a few autoclaves, or tubing that would leave behind a residue after aggressive cleaning agents were used. This Nalge Nunc product not only maintains its integrity but also consistently performs at a high level, ensuring the purity and safety of the fluids it handles. It has genuinely reduced my downtime and eliminated concerns about material-induced contamination.
