Dissolution tester with piston pump Rinse function for reducing carryover issues.

Tablet Dissolution Tester DS 8000 SMART with Piston Pump

The Labindia dissolution tester DS 8000 Smart with piston pump is a prefect semi automatic solution to carry out precise and efficient drug dissolution testing. Dissolution tester DS 8000 has 6 vessel temperature monitoring system that automatically measures and records the temperature of individual vessel at specified sample points.

With the high pressure Piston pump system rinsing is done between samples for reducing carryover issues. DTS technology for temperature allows to monitor dissolution vessel temperature accurately along with a external temperature sensor.

Having the 21 CFR Part 11 compliant software it is easy to search and print all Audit Trail activities. Multi level roles for users with password protection, expiry and complexity. PDF reports can be generated through the dissolution test system. This makes the Labindia dissolution tester the complete allrounder dissolution system available in the market.

Standard Features of Dissolution Tester DS 8000 SMART with Piston Pump
  • Advanced, Micro-Controller based (ARM Core): User-friendly, complies with current USP, BP, IP, JP & EP specifications.
  • Moulded water bath with 6+2 (3+1 & 3+1) vessel configuration enables comparative studies
  • Mono shaft design with easy changeover between Apparatus I & II eliminates routine height validation as per USP 
  • Automatic stirrer 25 mm depth positioning (as per USP requirement) • Paddles, Baskets and Vessels are laser marked with serial numbers for traceability 
  • Automated Tablet dispenser - drops 6 dosage form at single instance
  • Low Evaporation Lids: The conical shape low evaporation recovery 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 an external RTD Temperature Sensor (DTS - Digital Temperature Sensor)
21 CFR Part 11 Compliance
  • Audit Trail for all activities with search facility, report generation and printing
  • 200 & more User ID’s with alphanumeric entries of user name, password and role based privileges selection
  • Multi-level roles with password protection, expiry and complexity
  • User authentication is per formed for each and every operation done by user
  • PDF report file can be created through print
  • USB Printing eliminates the need of serial port to connect with instrument. The user can take printout on any local or network printer as well
  • Electronic signature functionality
  • Data Backup & Restore facility available
  • LAN (Ethernet) connectivity for Data backup on Network shared folder
Pump System - PP 08
  • Piston Pump - PP 08 is ideal for sample withdrawal from 6, 7/8 channels.
  • 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
Regulatory Compliance
  • DS 8000 SMART 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
  • Specially developed cleaning system to clean the entire sampling path after each run
  • Facilities to perform the dissolution test using 3 buffers (Buffer changing) to cater the application of enteric coating tablets
  • Recovery Test facility to study 100% Drug Dissolution
  • Split & on-time interval
  • Disposable Syringe & Filter attachment for manual sample collection.
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 mid way 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.
  • Inert PTFE Fluoropolymer Carrier Tubing
Sample Collection
  • 18 X 8 sets of samples can be collected. For more sampling interval, 24 X 8 collection trays are available
  • Option of 1.5mL & 2mL HPLC vial 24 X 8 tray is available
  • Auto recognition Sensor for tray with alarm 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
