    Abstract: A liquid dispensing device (100), in particular for watering animals, in particular laboratory animals, such as small rodents or the like, said device (100) comprising a main body (101) which defines a longitudinal cavity (1011) for the passage of watering liquids, said longitudinal cavity (1011) being in communication with the outside through a delivery (1002) and a discharge (1001) for introducing said liquids in said longitudinal cavity (1011) and discharging said liquids from said longitudinal cavity (1011) respectively, a valve body (105) and an annular shape elastic sealing element (120) arranged inside said longitudinal cavity (1011), said valve body (105) comprising a stem with a first portion (106) which extends through said annular sealing element (120) and a flange-shaped head (107), wherein said flange-shaped head (107) is kept pressed against said annular sealing element (120) by means of an elastic thrust element (130), and wherein said stem can switch between a first closing position, in which the flow of said liquid downstream of said annular sealing element (120) is prevented by said annular sealing element (120), and a second opening position, in which the flow of said liquids downstream of said annular sealing element (120) is possible.

    Abstract: A laboratory animal cage including a basin and a removable hood positioned which define an inner space that is closed and not accessible from the outside. The basin includes a flat bottom wall and sidewalls joined thereto, which define a first support edge. The hood is tray-shaped to define a second engagement edge and includes a main cover wall. Positioning the hood over the basin prevents the inner space from being accessed via the opposing first support edge and second engagement edge. With the bottom of the basin positioned on a support plane, the maximum distance between the first support edge and the support plane is 110 mm or less. Additionally, at least 50% of the inner surface of the bottom wall has a minimum height measurement to the inner surface of the hood of at least 127 mm, which is available for an animal.

    Abstract: Provided is an animal weighing scale that automatically measures a weight of an animal by a simple configuration. The animal weighing scale includes a breeding container for laboratory animals and a scale including a weighing pan supported by a weight sensor, the weighing pan is disposed inside a breeding space of the breeding container, and the weight sensor is disposed inside or outside the breeding space, and accordingly, based on a measurement value change when an animal inside the container is placed onto the pan, a weight change of the animal can be continuously recorded.
