Filtering and sampling device

A sampling device (20, 142, 152, 162, 172) for collecting a sample of a liquid sample is provided, the sampling device comprising a filter assembly (24, 142, 152, 162, 172), the filter assembly comprising a tubular container (30, 1430) and a plunger (40, 1440, 1540, 1640, 1740). The plunger (40, 144, 154, 164, 174) includes a plunger head (42, 144, 154, 164, 1742) and a plunger rod (82, 148, 1782) shaped to define an interior plunger space (86, 148, 158, 168, 178) having a plunger space proximal end opening (90, 1490, 1590, 1690, 1790) through a proximal end (88, 1488) of the plunger rod (82, 148, 178). The sampling device (20, 142, 152, 1620, 1720) is configured such that the filter (60) is removable from the tubular container (30, 1430) via the plunger space proximal end opening (90, 1490, 1590, 1690, 1790) while the plunger head (42, 1442, 1542, 1642, 1742) is within the tubular container (30, 1430). Other embodiments are also described. 提供了用于浓集液体样本样品的采样装置(20、1420、1520、1620、1720)，该采样装置包括过滤组件(24、1424、1524、1
