The polymerase chain reaction machine (often known as the PCR machine) can create an indefinite amount of copies of DNA samples.
Polymerase chain reaction
Amplification is the production of many copies of a particular DNA segment. The copying repeats - so that copies of the copies are made. This results in many, many copies in only a few cycles. PCR (Polymerase Chain Reaction) is the most common method of amplifying DNA.
One method of making copies of DNA is through a process called polymerase chain reaction (PCR). In PCR, a DNA template is mixed with primers, nucleotides, and DNA polymerase, and subjected to cycles of heating and cooling to amplify the target DNA region. This results in millions of copies of the DNA target.

Replication! 1) DNA splits 2) DNA copies 3) left with 2 copies of DNA! :)
Each cell in the human body typically contains two copies of DNA.
