1. A PCR container consisting of the following elements:
- a) a container that is suitable for PCR; and
b) has a closed end, an open end distal to the closed end, and a lumen; and
c) a wax attached to the inside surface of the container wherein;
d) the wax is at about the meniscus or above the meniscus position of a PCR mixture added to the container;
e) the wax does not completely occlude the lumen of the container such that the PCR mixture can be added to, the container below the wax without penetrating the wax;
f) the wax is solid at about 40°
C. or below 40°
C. and liquid above 40°
C.;
g) the wax, when liquefied, spontaneously covers the surface of the PCR mixture in the container; and
h) the wax is in an amount that, when liquefied, completely covers the surface of the PCR mixture, with the provision that the inside surface to which the wax is attached is not the bottom of the container and the PCR mixture has not been added to the container.

Abstract
The invention describes a polymerase chain reaction container and methods of using the same that greatly simplify and improve the polymerase chain reaction. Specifically, the invention describes a PCR container comprising a container suitable for PCR with wax attached to the inside surface of the container. The wax is positioned at or above an estimated meniscus position of a PCR mixture. The wax melts at PCR temperatures and covers the surface of the PCR mixture thereby prevents evaporation during thermal cycling. The invention is superior to current methods, in part, because it reduces preparation time, potential sources of contamination and adverse effects on PCR.
