• How to ***
• ① Insert the microcap into the cap until it is visible in the glass tube.
• ② There is a hole in the rubber ball at the top, and air passes freely, so the liquid rises by capillary action.
• ③ When the liquid is completely filled from *** to *** of the capillary, the microcap is collected at the specified volume
