MPC-1000-GF manual sample counter

The MPC-1000-GFW and MPC-100-GFL single-channel manual sample change low background counters are high performance low background counters. This type of counter provides new laboratories with a way to achieve low background alpha/beta measurement capabilities. It can be upgraded when the sample volume increases and a multi-detector system or automatic counting system is required to improve the measurement capability. The MPC-100-GFL counter equipped with a windowless gas detector provides the highest detection efficiency for low-energy Beta ray detection and alpha particle detection. Each counter can run programs and QC controls developed on DUO Express software, and the program can be transferred to the instrument via the PIC connection cable.
