14+2 position Dissolution Tester, 2 Motors

The PTWS 1420 is a 14+2-position, “dual 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>. The instrument features 14 testing positions and includes two additional standard size vessels for media refilling and reference standard media. PTWS 1420 features independent stirrer speed control for the left and right half of stirrers.

12 position Dissolution Tester, 2 Motor

The PTWS D620 is essentially a 12 position version 2 motor of the PTWS 620 with 12 working positions plus two addition vessels for blank (medium) and standard storage. The user may edit a testing procedure and file it within the Method filing system. User and acess rights administration are standard. All 12 stations are controlled by the same electronics so the rotation speed of all tools for example is identical.

The PTWS 620 model is generally preferred if manual sampling is the chosen option. The six in line (plus two stirred extra vessels) format places all vessels in front of the user. Also the "staggered start" option for each stirrer is a user friendly design as it allows manual sampling without any timing problems. As with the PTWS 310, the instrument offers testing method filing, user access administration, auto positioning of the vessels inside the water bath.

The PTWS 820D is an 8 position, single drive compact tablet dissolution testing instrument for solid dosage forms as described in USP chapter and EP section as well as the DAB and Japanese Pharmacopeia section . It is supplied with a staggered start feature for each of the eight positions. The upper drive is electronically controlled to offer two positions: an upper cleaning and a lower working position. The electronically driven lift mechanism is located centrally above the water bath. This assures that the whole lift drive mechanism is positioned in a way so that the tool shafts are always kept parallel and at a 90o angle to the vessel walls when in the working position.

The PTWS 120D is a 6 position, single drive compact tablet dissolution testing instrument for solid dosage forms as described in USP chapter and EP section as well as the DAB and Japanese Pharmacopeia section . It is supplied with a staggered start feature for each of the six positions. The upper drive is electronically controlled to offer two positions: an upper cleaning and a lower working position. The electronically driven lift mechanism is located centrally above the water bath. This assures that the whole lift drive mechanism is positioned in a way so that the tool shafts are always kept parallel and at a 90o angle to the vessel walls when in the working position.

The PT-DDS4 media preparation and degassing instrument is a vital part of a dissolution testing system. Deaerated media are critical to the reproducibility of dissolution results. The PT-DDS4 can prepare up to 25 litres of pre-heated media, which is degassed by a combination of heating, vacuum and circulation.

The PTFC-2/8 fraction collector can be attached to any Pharma Test dissolution bath. Using either a peristaltic-, syringe- or a valve-less piston pump, the dissolution media is directly sampled into covered glass vials inside the sampling dish of the PTFC-2/8. The PTFC-2/8 supports dissolution bath with up to 8 vessels. For baths with more positions, the PTFC-16 is available.

Manual sampling from a dissolution test instrument is not only time consuming but also limits the reproducibility and is close to impossible if sustained release products have to be analysed over prolonged time periods. The Pharma Test DSR-M (Dissolution Sampling Robot) provides a neat solution to this automation procedure.
