Abstract
A low tare weight filter system is disclosed. The low weight makes the system especially advantageous for use in inertial microbalance instrumentation where small variations in mass must be accounted for to deliver accurate results. Moreover, the assembly is constructed to permit the filter collector to flex and stretch over a complimentary body incorporated in a filter support base and securely fasten to the same. Such use offers further advantages for instrument performance. It insures consistent apposition and long-term stability in the contact between the filter media and its reference surface.
