The sample concentrator is suitable for the concentration of multiple samples in a heating block, using a system of low-pressure injection of inert gas (usually nitrogen) on the surface of the sample, which in combination with the heating block produces ideal conditions for a rapid and efficient evaporation. The gas injection is performed through a needle inserted into a silicone membrane, which is adjustable in height by a precision rack system.rrThe sample concentrator includes gas chamber and the tube holder. Needles, heat block heating and aluminum blocks must be ordered separately.r
