VWR Hydrometer Bat W/SYPHN Set. The polystyrene makes the instrument lightweight and robust giving accurate repeatable results. All units are shipped with a Syphnometer adaptor complete with a digital manometer lattice hydrometer hollow glass stopcock and goggles. The units can be stacked together to form a reservoir and they fit snugly into the stopcock sleeve. The stopcock stores in the end nearest the hydrometer making its location obvious. Then a plastic tubing is laid over the stopper and the hydrometer along with its integrated holder are stored in a nylon bag to keep clean. The stopcock is moved to the front of the hydrometer making it easier to read than the meter being used.
