The 4.00ml tube with external thread has a massive working volume. The sample storage tube is ideal for solid or large volumes of liquid samples. Using externally threaded storage tubes eliminates the possibility of the sample coming into contact with the screw thread, minimizing chance of cross-contamination while improving sample integrity. This and the sturdy design of the tube make the 4.00ml tube with external thread suitable for high speed centrifuging. On the other hand, the wide opening and flat inner bottom enable easy loading and removal of tissue samples using tweezers.
Micronic 4.00ml tubes with a 2D Data-Matrix code permanently laser-etched on the bottom of the tube are the storage medium of choice for customers demanding long-term reliable code reading. The code surface of the tubes with external thread features a raised edge, which protects the 2D code against accidental scratches, ensuring absolute traceability.
