PCR tubes are small, thin-walled tubes used in polymerase chain reaction (PCR) to amplify DNA. They are made of polypropylene, which is resistant to heat and chemicals, and have a volume of 0.2mL or 0.5mL. PCR tubes are usually sold in strips or racks of 8 or 12 tubes.

There are two main types of PCR tubes: skirted and non-skirted. Skirted tubes have a flat bottom and a raised rim around the top, which makes them easier to handle. Non-skirted tubes have a round bottom and no raised rim. Both types of tubes are available in a variety of colors, including clear, white, black, and blue.

PCR tubes are an essential part of PCR, and they offer several benefits over other types of tubes. PCR tubes are thin-walled, which allows for efficient heat transfer and reduces the chance of thermal gradients. They are also chemically resistant, which makes them compatible with a wide range of PCR reagents. Additionally, PCR tubes are available in a variety of sizes and formats, which makes them suitable for a variety of applications.

PCR tubes should be stored in a cool, dry place away from direct sunlight. They should not be exposed to extreme temperatures or humidity. If PCR tubes are not stored properly, they may become brittle or deformed, which can affect their performance in PCR.
