ABSTRACT:
A flask for standard solutions comprises a flask body and a closure cap for sealingly closing the flask body. It has in an upper part of the flask body a capillary passage communicating with a chamber for containing the solution. The flask is filled and/or emptied through the capillary passage. The capillary passage acts as a recondensation zone and reduces evaporative escape of solvents upon removal of the liquid, even when the closure cap is closed. The risk of contamination of the solution in the flask is also reduced. The narrow opening of the capillary passage can be sealingly closed with the closure cap of the flask. After the closure cap is removed the solution can be easily completely removed through the capillary passage using a syringe, without having to tilt the flask.
