Tablet Dissolution Test Apparatus DS 8000+ with Piston Pump and Filter changer


Dissolution Tests are conducted to determine the drug release patterns, physiological availability and bioavailability of for mulated drug products. It is also used as a quality control tool. The Dissolution rate of a dr ug from the solid state is defined as the amount of dr ug substance that goes into solution per unit time under standardised conditions of liquid / solid inter face, temperature, and solvent composition.

LABINDIA brings to you the State-of-the-art Dissolution Testing Apparatus in elegant design with advanced features, which supports USP 1, 2, 5 & 6. Apparatus for Intrinsic test & stationar y basket methods are available.



• Advanced, Micro-Controller based: User-friendly, complies with current USP, IP & EP specifications.

• Splash waterproof keyboard: Alphanumeric polyester soft keys for keyboard.

Moulded water bath with 6+2 (3+1 & 3+1) vessel configuration enables comparative studies.

• External vibration free Water Circulator: for uniform water circulation, with audible, low water level alarm, with indication on display for safety.

• Mono shaft design with automatic adjustment for 25 mm depth setting with easy changeover between Apparatus I & II eliminates routine height validation as per USP.

Paddles, Baskets and Vessels are laser marked with serial numbers for traceability.

• Tablet dispenser - drops 6 dosage form at single instance.

• Low Evaporation Lids: » The conical shape low evaporation recover y lids reduces media loss during long run.

» Integrated pre-centered lids; no manual removal or positioning of lids. This ensures automatic vessel centering and precise

positioning of paddle/basket with shaft without any special tool as per pharmacopeia requirements.

• State-of-the-art design:

» Easy placement and locking of vessels, the Ease-align system allows the vessels to simply slide into the place (Bionet Locking).

Once placed, vessels do not float even when empty.

» Facility to monitor Vessel temp., with DTS Technology (Digital Temperature Sensor)



• DS 8000 meets all requirements relating to validation, qualification and calibration.

• Appropriate qualification documents (I.Q. / O.Q.) can be supplied with the instrument.



• Automated sampling as per USP Specifications. Sampling tubes are lowered in the media only at the time of sampling and withdrawn immediately after sampling, thus no par t of the assembly contributes motion, agitation or vibration.

• Sampling tubes are accurately moved to the USP sampling position i.e. a zone mid way between the sur face of media and the top of

paddle/basket parameters, not less than 1 cm from the vessels wall as selected in the method.

• 6 vessels temperature monitoring system automatically measures and records the temperature of individual vessel at specified sample points.



• Piston Pump - PP 08 is Microprocessor controlled and is ideal for sample withdrawal from 6, 7, 8 channels

• The Piston Pump - PP 08 with iner t ceramic rotor overcomes all absorption issues

• High flow rates of 25 ml / min can be achieved with accuracy better than ±5%

• Rinse function for reducing car ryover issues

• Surfactant Media Compatibility



• Automatic Filter changer FC 08 is Microprocessor controlled and designed to filter 6, 7, or 8 sampling lines simultaneously.

• Accessory for Inline Filtering of Sample before collection through Syringe Filters

• FC 08 is used in conjunction with high pressure LABINDIA Piston Pump-PP 08 with filtration down to 0.22 & 0.45 μm

• High Storage capacity – up to 96 filters at a time gives uninterrupted filtered sample collection for 16 Sampling Points.

• Individual channel Sensors to ensure filters are in place.

• Incase the syringe filter is missing, automatic switch-over of valves to collect unfiltered sample, with an indication in the printout



• 10 X 6 or 16 X 6 sets of samples can be collected. For more sampling interval, 24 X 6 collection trays are available.

• Option of 1.5ml & 2ml HPLC vial tray is available.

• Over Head Design for electronic safety and fail safe operation

• Sensor to locate proper position of tray with alar m facility for collection of sample

• Wide mouth vial to minimise SLS spillover problem due to foaming characteristics

• Easy positioning with respect to vials or test tube tray for easy changeover



• Built-in Validation software.

• Facility to RINSE the entire sampling path in between sampling time-point to eliminate contamination & carryover

• Specially developed cleaning system to clean the entire sampling path after each run.

• Facilities to perform the dissolution test using two buffers (Buffer changing) to cater the application of enteric coating tablets.

• Recovery Test facility to study 100% Drug Dissolution.

• Split & on-time interval



• Control: Micro controller based (Advanced version of microprocessor).

• Display: 40 x 2 line back lighted liquid crystal display (LCD)

• Keyboard: Alphanumeric splash waterproof polyester sof t keys.

• Method Storage: 15 programs with parameters.

• Data Storage: Available with Non-Volatile memory.

• Water Bath: 17 litres capacity with built-in water level sensor / Front located drain tap for easy draining of the water bath.
