What makes these culture tubes stand out?

Eliminate Spillage Risk

Our unique screw cap culture tubes prevent liquid spillage and provide a stable, secure opening that protects your samples. Unlike plug cap tubes, our screw caps won’t pop off during high-speed centrifugation, ensuring safe and reliable use.

Easy Labeling and Writing

Our bacterial culture tubes have a large white area on the body for easy labeling. The flat cap allows for writing and attaching labels, making them more convenient for lab use.

One Tube, Two Purposes

GenFollower’s bacterial culture tubes have two main uses.
a. Aerobic culture: Rotate the cap a quarter turn until you hear the first click. The tube is now ready for aerobic culture.
b. Anaerobic culture: Rotate the cap a half turn until you hear the second click. The tube is now ready for anaerobic culture.
