These seripettor® pro dispensers offer the rugged versatility and low lifetime cost of the regular seripettor and handle a wider range of liquids. Ideal for customers who do not require all the features of the Dispensette® dispensers. Seripettor pro dispensers are threaded to fit directly onto 45-mm screw-neck bottles; adapters for S40, 33- and 38-mm bottles are included. Order bottles separately.
