Abstract
A draft protection device for a laboratory instrument. The device encloses a weighing compartment that surrounds a balance pan. The draft protection device includes a rear wall, a front wall, two sidewalls, a top cover, and a floor that is delimited by border edges. The draft protection device further includes at least one guiding means that is connected to the top cover and serves to guide the movement of at least one horizontally slidable sidewall, and/or a holder means that is connected to the top cover and serves to hold the front wall in place, wherein the guiding means and/or the holder means supports the weight of the at last one sidewall and/or the front wall in such a way that the wall(s) is pushed by a biasing torque against the floor of the weighing compartment. This torque is supported by the border edge facing towards the respective wall.
