Polymerase chain reaction apparatus
First Claim
1. A PCR apparatus comprising:
- a specimen chamber;
a heating conduit which communicates with the specimen chamber;
a cooling conduit which communicates with the specimen chamber;
a pumping device for pumping a gaseous or liquid medium through the heating conduit and the cooling conduit to the specimen chamber;
a heating device, disposed separately from the cooling conduit, which communicates with the heating conduit and is operable to heat the medium located in the heating conduit; and
a mixing device which communicates with the heating conduit and with the cooling conduit such that a ratio between a volume of the medium flowing per unit of time through the heating conduit and a volume of the medium flowing per unit of time through the cooling conduit to the specimen chamber is adjustable by the mixing device.

Abstract
A PCR apparatus has a specimen chamber, a heating conduit which communicates with the specimen chamber, a cooling conduit which communicates with the specimen chamber, and a pumping device for pumping a gaseous or liquid medium through the heating conduit and/or the cooling conduit to the specimen chamber. The PCR apparatus further has a heating device, disposed separately from the cooling conduit, which communicates with the heating conduit and heats the medium located in the heating conduit c. The PCR apparatus has further a mixing device, which communicates with the heating conduit and with the cooling conduit, such that a ratio between a volume of the medium flowing per unit of time through the heating conduit and a volume of the medium flowing per unit of time through the cooling conduit to the specimen chamber is adjustable.

11. A PCR apparatus comprising:
-
a specimen chamber;
a heating conduit which communicates with the specimen chamber;
a cooling conduit which communicates with the specimen chamber;
a pumping device for pumping a gaseous or liquid medium through the heating conduit and or the cooling conduit to the specimen chamber;
a heating device, disposed separately from the cooling conduit, which communicates with the heating conduit and is operable to heat the medium located in the heating conduit; and
a mixing device which communicates with the heating conduit and with the cooling conduit, such that a ratio between a volume of the medium flowing per unit of time through the heating conduit and a volume of the medium flowing per unit of time through the cooling conduit to the specimen chamber is adjustable by the mixing device, wherein the mixing device includes a valve, which varies one of the volume of the medium flowing through the cooling conduit and the volume of the medium flowing through the heating conduit. - View Dependent Claims (12, 13, 14, 15)
