Tablet Dissolution Tester DS 8000+ with Piston Pump

The Labindia dissolution tester DS 8000 with piston pump is a prefect semi automatic dissolution testing solution to carry precise and efficient drug dissolution. Mono shaft design allows easy changeover between apparatus I and apparatus II thus eliminates routine height validation checks as per pharmacopeia.

Piston pump PP 08 is microprocessor controlled and ideal for sample withdrawal from 6, 7 or 8 channels. All types of media like surfactant are compatible without any effect on the sample volumes. This dissolution tester contains an inert ceramic rotor in the piston pump PP 08 overcomes all absorption issues.

Over head design of the sample collector give electronic safety for fail safe operation. With a choice of trays the user has a flexibility to choose between test tubes or standard vials that can be used in dissolution testing.

Standard Features of Tablet Dissolution Tester DS 8000+ with Piston Pump

  • User-friendly, complies with current USP , IP ,BP & EP and ASTM specifications.

  • Alphanumeric polyester soft keys for keyboard.

  • External vibration free Water Circulator for uniform water circulation with audible and low water level alarm.

  • 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.

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

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

Sample Collection

  • 12 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 vials 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

Pump System - PP 08

  • Piston Pump - PP 08 is ideal for sample withdrawal from 6 ,7/8channels.

  • The Piston Pump - PP 08 with inert ceramic rotor overcomes all absorption issues.

  • Accuracy better than ±2%.(@10mL)

  • Rinse function for reducing carryover issues.

  • Surfactant Media Compatibility.

Intelligent Sampling System

  • 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 part of the assembly contributes motion, agitation or vibration.

  • Sampling tubes are accurately moved to the USP sampling position i.e. a zone midway between the surface 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 & records the temperature of individual vessel at specified sample points.

Regulatory Compliance

  • DS 8000+ with Piston Pump meets all requirements relating to validation, qualification and calibration.

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

Additional Features

  • Built-in Validation software.

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

  • 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


  • Alphanumeric entries of Sample Name, Sample Number and Identification Number for authentication.

  • Built-in Real Time Clock (RTC) for date and time on display and on printout.

  • Daily Auto Incremented Run Number and factory entered CUSTOMER NAME with Instrument Serial Number on report printouts

  • Non-Volatile memory storage methods with parameters.

  • Two tier password protection of Admin and User

  • Reports can be obtained even after Resetting / Power off / Power failure conditions.

  • Error indication helps user to trace the problem.

  • Audible indication for ready state of instrument.

  • Validation Software to validate RPM, Temperature, sampling volume & replenish volume.
