Real-World Testing: Putting VWR SuperClear Ultra-High Performance Centrifuge Tubes with Flat or Plug Caps, Polypropylene 3132-340-306 Tubes With Plug Caps to the Test

First Use Experience

My first real test of these tubes was in the field, collecting samples from geothermal hot springs in Iceland. The harsh conditions—near-freezing air temperatures punctuated by the intense heat and humidity of the springs—demanded equipment that wouldn’t falter. I used the tubes to collect water and sediment samples, which then needed to be centrifuged on-site using a portable, battery-powered centrifuge.

The tubes performed flawlessly, even after being subjected to rapid temperature changes as they were transferred from the frigid air to the warm centrifuge. The plug caps created a reliable seal, preventing any leakage during high-speed spinning, which was a huge relief considering the valuable and potentially hazardous nature of the samples. There was a slight learning curve in ensuring the plug caps were properly seated to guarantee a leak-proof seal, but this became second nature after a few uses.

Extended Use & Reliability

After months of using these tubes in various environments – from the arid deserts of the American Southwest to the humid rainforests of Southeast Asia – I can attest to their durability. I’ve used them to store samples at -80°C for extended periods, and transported them in less-than-ideal conditions, strapped to backpacks or bouncing in the back of a truck. There have been no issues with cracking or leakage.

The graduations on the tubes remain clear and legible even after repeated autoclaving and exposure to various solvents. Cleaning is easy, thanks to the smooth inner walls, and the polypropylene material hasn’t shown any signs of degradation. These tubes have significantly outperformed some of the “premium” brands I’ve used in the past, especially considering their resistance to cracking when frozen.

Breaking Down the Features of VWR SuperClear Ultra-High Performance Centrifuge Tubes with Flat or Plug Caps, Polypropylene 3132-340-306 Tubes With Plug Caps
