CambTEK RES: Features


The CambTEK RES is at the cutting edge of fully automated sample preparation of dosage forms, in development and quality assurance laboratories, and manufacturing environments. From Phase 1 Development through to Manufacturing Quality Assurance, the RES will improve quality of data, and increase productivity.

The RES has been designed to prepare a vast range of dosage forms, including:

  • Tablets (both normal and prolonged release)
  • Capsules
  • Powders
  • Liquids
  • Gels
  • Pastes
  • Swabs
  • Stents
  • Beads
  • Intermediate Granulations
  • Pellets
  • Solid & Semi-solid Matrices
  • Suppositories

The RES uses turbulent fluidic flow with solvent quantities from 50 mL-500 mL with optional ultrasonic energy to extract samples. Pump speed is adjustable from 70 mL/min to 1 L/min approximately, giving full control of the extraction process, allowing the RES to perform a wide range of functions, including:

  • Content Uniformity Testing (CU)
  • Impurity Testing (imps)
  • Composite and Bulk Assay Testing Stability Assay Testing (ICH)
  • Blend and Granulation Uniformity Testing

After extraction, the solution is filtered and the filtrate delivered to a primary 20 mL vial ready for dilution or directly to an HPLC vial for analysis. All dilution and dispensing steps are performed with gravimetric feedback, delivering high repeatability and ASTM Class A dispensing accuracy. The RES then automatically performs a cleaning and drying cycle, ready to process the next sample.

Other features include:

  • 5-channel solvent selection allows for complex extractions
  • Off-line and adaptable for on-line with HPLC or UV/MS analysis
  • Powerful extraction for unstable compounds with or without ultrasonics
  • Robustness testing/design space of analytical test methods to investigate the envelope of extraction and dilution process
  • Highly variable working sequence giving random access workflow
  • System achieves clean & dry state between samples allowing for full flexibility of consecutive sample types

Quality of Data

CambTEK has worked with analytical chemists from leading Pharmaceutical Companies in the design and testing of the RES, to ensure the common concerns within the industry were addressed.

  • Designed to highest standards to ensure regulatory and quality compliance of data integrity, validity and repeatability
  • Sanitary design of fluidic path, minimising leeching and carryover : studies with difficult to clean compounds show < 0.1% carryover is achievable with minimal wash steps
  • Developed to exceed ASTM Class A volumetric requirements with sophisticated gravimetric feedback for closed loop confirmation of dispensing processes
  • Eliminates potential variability due to analyst technique or human error
  • Sample barcode tracking provides improved chain of custody to improve compliance
  • 21 CFR Part 11 compliance
  • In-process data for checking and conformity, answering ‘who?’, ‘when?’, and ‘what?’ queries
  • Comprehensive post-extraction report allows for detailed Out Of Specification (OOS) investigations
  • On-line video monitoring* assists method development and atypical OOS investigations
  • Sealed vials maintain sample integrity
  • Enclosed system for additional safety and sample integrity

Standardization & Compliance

Platform technology for site and user independent standardization of results, from R&D through to manufacturing.

  • Supporting R&D laboratories performing DoE and new product developments supporting Quality by Design (ICH Q8)
  • Pressure monitoring allows end-point confirmation, aiding method development
  • Fluidics and Sonication provides good equivalency to manual methods, minimizing re-validation from manual processes to automation
  • Comprehensive encrypted and secure documentation complies with 21 CFR Part 11
  • User access rights control method approval and status


Support and improve your lean sigma initiatives and gain productivity.

  • Minimal user touch-time and fast setup and operation
  • Robust design and component specification for minimal downtime and maximum reliability
  • Work 24/7 with 30 sample capacity, plus batch load operation
  • Smart carousel load and scan
  • Easy maintenance design and software control
  • Suitable for At-line testing


All aspects of the instrument are easily configured using the intuitive Graphical User Interface (GUI), from setup to method development to operation.

  • Designed for intuitive operation with simple walk-up, scan, load, and run features
  • Press “Play & Go” design concepts Barcode workflow removes need for sample placement cross-referencing by the operator
  • Consumable set designed for prescriptive operation and user error reduction, independent of user experience or ability

Health & Safety

i) User:

Automated closed system reduces analyst exposure to solvents, excipients and active pharmaceutical ingredients.

ii) System:

  • Main pump has a physical safety feature to prevent over-pressurizing of the system
  • Leak sensor increases safety of operation, and minimizes wasted samples
  • Pump revolutions are monitored and an on-screen message advises when tubing needs replacing
  • ‘Watchguard System’ monitors the entire system in operation, and where possible, recovers instrument to a working state after any stop event


RES delivers economic benefits by reducing manual sample preparation tasks, standardizing processes, reducing errors, and increasing laboratory productivity.

  • Intuitive ease of use to increase productivity and reduce cost per test
  • Reduction in associated solvent purchase and disposal costs
  • Flexible payment options to overcome common laboratory budget constraints
