A PCR Deep Well Plate is a specialized type of laboratory plate used for polymerase chain reaction (PCR) experiments. It is a plate with multiple wells (usually 96 or 384 wells) that are deeper than traditional microwell plates, allowing for larger volumes of liquid to be used in each reaction. PCR deep well plates are made of various materials such as polypropylene, polycarbonate, or glass, and are designed to be compatible with thermal cyclers, which are the instruments used to amplify DNA in PCR reactions.

A sampling swab is a small, sterile, absorbent tool used to collect samples of liquid or material, such as saliva, blood, or mucus, from surfaces or body cavities. Sampling swabs are commonly used in medical and laboratory settings for tasks such as co samples for culture, PCR, or DNA analysis. They are often made of foam, rayon, or nylon, and have a handle that allows the user to hold and manipulate the swab. Some SAMPLING SWAB are individually packaged to maintain sterile conditions, and others are packaged in bulk for convenience.
