The fully automated 4 in 1 tablet testing instrument PTB 420 Auto is a dual test mode instrument to determine the weight, diameter, thickness and hardness of tablets. The instrument is made in strict compliance with the EP and USP Pharmacopoeia. PTB 420 Auto features an integrated Sartorius analytical balance module to determine individual sample weights and a tablet feeder for up to 25 samples. Prior to testing the hardness of the tablet the PTB 420 can measure sample thickness (or height) and diameter (or length). The thickness is detected automatically by an optical system. The samples are automatically positioned by means of the patented movable alignment jaws. The behaviour of the jaw’s movement is adjustable to accommodate many different shapes of tablets and oblongs. The instrument can be set to either linear force or linear speed increase mode for the tablet hardness test. PTB 420 Auto offers two modes for the weight measurement: either weigh each sample individually, before placing them into the tablet magazine or weigh all samples together and calculate the average weight.
