Abstract
The invention relates to a collector which is able to take small samples of possibly hazardous dusts lying scattered on a surface. The invention consists of an evacuated sampling bottle closed with a septum, which is to be provided with a telescopic cap which has a contact plate shaped for removing the dust or liquid sample from a small surface by suction and a needle which can puncture the septum. The sample bottle can be filled with a small amount of liquid to take up the dust. When the sample bottle is held in the hand and the cap is pressed onto a surface which is coated with dust or liquid droplets, the needle punctures the septum and the vacuum sucks some of the dust or liquid droplets into the sample bottle.
