Lab Tubes main types include:
Ordinary test tube: The most common type of test tube, usually made of glass or plastic, is suitable for a variety of routine experiments.
Scale test tube: with volume scale, easy to measure liquid volume.
Centrifugal tube: Designed for use in high-speed centrifuges that can withstand high centrifugal forces, it is often used to separate components from mixtures.
Freeze-storage tube: Specially designed for the cryogenic preservation of biological samples, it can store samples for long periods at -80°C or even liquid nitrogen temperatures.
PCR tube/plate: For polymerase chain reaction (PCR), usually made of clear plastic, with single or multiple pore sites.
Colorimetric tube: having a uniform diameter, suitable for color comparison experiments or spectral analysis.
