The PTWS 120S is a 6-position, multiple drive, compact tablet dissolution testing instrument for solid dosage forms as described in USP chapter <711/724> and EP section <2.9.3/4> as well as the BP, DAB and Japanese Pharmacopeia section <15>. Its design for manual operation and ease of use.

Advantages:
>> 6 stirring positions, individually electronically regulated high precision drive system for each one of the 6 stirrers.
>> Grouping of stirrers, like 2 groups of 3, or 3 groups of 2 running at the same speed
>> Modular design to minimize bench space requirements
>> 3-point individual vessel centering system
>> Borosilicate glass vessels including extra low evaporation vessel covers
>> Individual vessel batch code at the top of the vessel flange for easy identification
>> Excellent access to all vessels
>> Eco saving double walled vacuum molded water bath
>> Motorized Drive Head lifting mechanism including head position programming facility
>> Screen saver functionality and count-down timer offers most important information at a glance (stirrer speed, bath temperature, time to next sampling interval, elapsed time, media temperature etc.)
>> Wake up functionality to start heating at a pre-programmed time
>> Ultra-fast heating system due to newly designed heat exchanger, saves up to 1/3rd of the heating up time compared to most other models
>> MonoShaft™ system to avoid re-adjustment of immersion depth
>> Staggered stirrer start feature for convenient manual sampling
>> Water diffuser inside the vacuum moulded water bath for even temperature distribution and fast temperature equilibration
>> Spring loaded pump assembly to eliminate vibration transfer
>> Extraordinary safety features for pump and heating system, flow control, digital temperature control, thermo switch, thermo fuse
>> Auto stirrer stop when drive lift is moved
>> Excellent stirrer shaft verticality inside the vessels due to central position of lift columns, drive head assembly and rigid anodized aluminum framework
>> Easy removal of the water bath from of the frame work for cleaning and maintenance work
>> Energy saving double walled bath option, less heat transfer into the lab environment, less power consumption during instrument operation
>> DQ/QC, IQ and OQ documents included free of charge
