Printing function with automatic solvent mixing device

PROBLEM TO BE SOLVED: To provide an automatic solvent mixing device with a printing function that can automate measuring, mixing, and identification table printing work simply by inputting numeric values in the device and operating it, reduce preparation operations, prevent erroneous measuring, and perform identification table creation work.SOLUTION: An automatic solvent mixing device with a printing function includes: piston syringes 3 and 4 for sucking and discharging a solvent; a switch valve 5 for switching a path between a path for sucking the solvent in the piston syringes from solvent bottles 1 and 2 installed at a position higher than the switch valve 5 and a path for discharging the solvent to a solvent mixing bottle 6 from the piston syringes; a touch panel 7 for inputting setting values of a mixing ratio and a mixing amount of the solvent; a control roller 9 for controlling the piston syringes 3 and 4, and the switch valve 5; and a printer 8.
