45-mm threaded base with adapters for 32-, 38-, and 40-mm bottles; alternative screw-type volume setting button; 120-mm long delivery jet with stopper; and 350-mm long feed tube.
The solutae 530 model has a PFA-coated glass plunger for trouble-free dispensing of salt solutions, and both weak and strong acids or bases. A built-in calibration system, hidden under the cap, allows for simple adjustment to accurately accommodate solutions due to varying viscosity or temperature. Two volume adjustment knobs are included—use the premounted slider when changing dispensing volumes frequently or the screw-type version for a more permanent setting without the risk of accidental changes.
