Avoiding Electrostatic Charges; Liquid Dosing; Attaching The Dosing Head To The Bottle Cap - Mettler Toledo Q3 Manual De Usuario

5.4.4 Avoiding electrostatic charges

When preparing sample vessels, electrostatic charge may build up. Electrostatic charges may make correct
dosing impossible or adversely affect the dosing result.
Factors increasing the amount of electric charges:
using sample vessels made of plastic
wearing latex gloves
The integrable antistatic kit is used to remove electrostatic charges from sample vessels. This antistatic kit is
especially designed for dosing purposes and consists of two ionizing electrodes, one placed on each side of
the weighing chamber. The electrodes can be activated automatically when dosing or manually. Using those
two electrodes helps removing electrostatic charges from sample vessels.
Make sure to install a dosing head before placing the sample vessel on the weighing pan. This way, ionizing is
active while placing the sample vessel on the weighing pan and electric charges are neutralized. In addition,
try not to touch the upper edge of the sample vessel, e.g., close to a vial opening, when handling it.
