Nano ITC Getting Started Guide Page 15Each syringe needle is equipped with a flattened, twisted paddle at the tip, which does the actual stirring ofthe solutions in the cell. The stirring paddle spins clear of the sides of the reaction vessel. When stirring isactivated, the contents of the reaction vessel are stirred continuously until the end of the experiment oruntil stirring is turned off.Stirring is controlled by a stepping motor mounted inside the calorimeter. This type of motor is usedbecause of its very constant and adjustable speed. The motor drives the rotating shaft of the buret, whichholds the titrant syringe.Buret AssemblyThe buret accurately delivers the titrant to the reaction vessel at specified volumes and intervals. Theassembly also functions as the stirring mechanism for the reactants in the cell when the titrant syringe isinstalled. The rotating shaft on the lower portion of the buret assembly holds the titration syringe in place,and has two external o-rings which provide the friction necessary for the stir motor to rotate the shaftduring operation.See online help for details on using the buret.Options and AccessoriesA degassing station is available to complement your Nano ITC instrument.
