What is the size of PCR tube?

PCR (polymerase chain reaction) tubes come in a variety of sizes, but some common sizes are:

– 0.2 ml tubes – These are small thin-walled tubes that typically hold 20-50 μl reaction volumes. They are one of the most commonly used PCR tube sizes.

– 0.5 ml tubes – Slightly larger tubes that hold 50-100 μl reaction volumes.

– 1.5 ml tubes – Larger tubes that can hold 100-200 μl reaction volumes. Good for larger reactions or final storage of PCR products.

– 0.1 ml tube strips or plates – These hold 8, 12, or 24 x 0.1 ml tubes that are good for multiple smaller volume reactions. The tubes are attached so the entire strip/plate can be handled together.

– 0.2 ml tube strips or plates – Same as above but with 0.2 ml tubes.

So in summary, PCR tubes range from 0.1 ml to 1.5 ml in size, with 0.2 ml and 0.5 ml being very common volumes used. The choice depends on factors like reaction volume and throughput needs. Smaller tubes are preferred when possible to minimize reagent usage.
