These tubes deliver top-notch results, whether you’re spinning samples at high speeds or storing them for a long time.

2. Superior Protection Against Contamination

Made in a Class 100K clean room, these tubes have no risk of contamination. The production doesn’t involve any secondary assembly or any manual handling in between for O ring infusion in caps, which ensures a clean environment.

Plastic Tubes vs. Glass Tubes: Why Plastic is the Better Option

When comparing plastic and glass tubes plastic tubes—such as Accumax Screw Cap Tubes—have several important benefits:

1. Toughness and Ability to Withstand Impacts

Plastic screw cap tubes last much longer than glass tubes and are less prone to breaking even when hit hard. This helps a lot in busy labs where people might drop things by accident. Because plastic resists impacts so well, it lowers the chance of expensive and dangerous breaks keeping important samples safe.

2. Light and Easy to Handle

Plastic screw cap tubes weigh less than glass, which makes them simple to handle, move, and keep. This matters a lot when you’re working with many samples or moving them between different places. The light weight of plastic also helps cut down on tiredness during long lab work.

3. Cheap and Throwaway

Plastic screw cap tubes cost less than glass ones. You can throw them away after using them, which means you don’t need to clean and sterilize them like you do with glass tubes. This saves time and cuts down on running costs, making plastic tubes cheaper to use over time.
