Abstract:
An apparatus for controlling the temperature of at least one liquid reaction mixture, the apparatus comprising:(a) at least one reaction vessel having open proximal and distal ends, said at least one reaction vessel including a gas permeable, liquid retaining, barrier being positioned at a proximal portion thereof,(b) a pump being in fluid communication with said proximal end of said at least one reaction vessel through said barrier, for generating negative or positive pressure within said at least one reaction vessel, for translocating the at least one liquid reaction mixture through said distal end into and out of said at least one reaction vessel, wherein the at least one liquid reaction mixture is retained within said at least one reaction vessel via said negative pressure generated therein by said pulp, thereby obviating a need of sealing said distal end; and(c) a temperature controller being in thermal communication with said at least one reaction vessel for controlling the temperature of the at least one liquid reaction mixture when maintained within said at least one reaction vessel.
