Automating Dissolution Testing With a High Precision Data Acquisition Dissolution System
2026-04-17
When you automate dissolution testing with a High Precision Data Acquisition Dissolution System, you eliminate manual variability and finally achieve true walk-away efficiency in pharmaceutical QC.
Introduction
For busy quality control laboratories, manual dissolution testing is a hidden bottleneck. From dosing to positioning sampling needles, to logging temperatures and speeds, followed by manual data transfers, there are numerous opportunities for errors. By 2026, forward-thinking procurement teams will be upgrading obsolete testers with High Precision Data Acquisition Dissolution Systems and completely automating the workflow.
Raytor’s RT600 Dissolution Apparatus is built for exactly this mission. It combines automatic dosing, automatic positioning, real-time monitoring, and infinite data storage into one compliant platform. Below, we break down how automation transforms dissolution testing – and why the RT600 is the smart choice for forward-looking labs.
Why Automation Is No Longer Optional
Manual dissolution testing creates three costly problems:
• Inter-operator variability: Different technicians produce different results, hurting reproducibility.
• Data gaps: Handwritten logs are easily lost or manipulated – a direct 21 CFR Part 11 violation risk.
• Low throughput: Time spent on setup and manual recording means fewer tests per day.
• A High Precision Data Acquisition Dissolution System solves all three by taking human hands out of the critical steps.
Key Automation Features of the RT600
Raytor designed the RT600 to automate every phase of dissolution testing, from preparation to data archiving.
- Automatic Synchronous Dosing – Guaranteed Consistency Every Run
• What it does: This system enables simultaneous dosing of all eight vessels at any programmed time.
• Why it matters: This system completely eliminates time-of dosing differences that could lead to early-timepoint dissolution results variability.
• Traceability: The time of dosing is recorded and captured automatically, with no manual effort.
- Automatic Positioning of Sampling Needles
• How it works: The sampling needle is able to lower to a depth that corresponds to the set solvent volume (e.g., 500 mL, 900 mL).
• User benefit: No ruler, no guesswork, no vessel-to-vessel variation.
• Bonus: Non-resident sampling needles retract between samplings, reducing turbulence that could affect dissolution profiles.
- Real-Time Display of Speed and Temperature
• Live parameters: Speed (0–300 rpm, resolution 0.01 rpm) and temperature (accuracy ±0.2°C, resolution 0.01°C) are shown continuously.
• Automated logging: The High Precision Data Acquisition Dissolution System writes these values to internal memory at user-defined intervals.
• Alerts: Instant notification if speed drifts beyond ±0.3 rpm or temperature exceeds ±0.2°C.
- Preheat with Medium Automatic
• Fast start: Instead of manually preheating, schedule a bath to begin heating at 6:00 AM. By 9:00 AM, the medium will be at a precise 37.0°C ±0.1°C.
• Energy intelligent: Heats only when necessary, not overnight.
• Audit ready: The preheating schedule is logged and time-stamped.
- Infinite Data Storage – Never Delete a Run
• No upper limit: Store years of dissolution profiles, method parameters, and calibration records on the system.
• Searchable archive: Retrieve any old run by date, operator, or product batch.
• Part 11 ready: Data cannot be altered or deleted without proper permissions.
How Automation Improves Compliance With USP, EP, and Chp
The RT600 fully satisfies USP <711>/<724>, EP 2.9.3/4, and Chp 0931. But automation takes you beyond simple compliance:
• Vessel verticality (90° ±0.5°) and centering deviation (< ±2.0 mm): Automatically maintained by the self-centering dissolving cups – no manual alignment needed.
• Shaft wobble (< ±1.0 mm): The paddle-basket coaxial design ensures wobble stays within limits even after switching methods.
• Temperature uniformity: The round-corner water bath eliminates dead circulation zones, so every vessel sees the same temperature without manual stirring.
All these mechanical parameters are verified at the factory and documented in the RT600 validation brochure (PDF).
2026 Design Trends That Favor Automation
Procurement teams this year are prioritizing systems that reduce hands-on time. The RT600 matches three major trends:
• Walk-away operation: Set up a 12-hour dissolution run with automatic sampling intervals. Return the next morning with complete, audit-ready data.
• Method flexibility: Switch between basket and paddle without readjusting dissolution unit height. The system remembers your parameters.
• Low cleaning effort: One-piece, rounded water bath corners and non-resident needles mean faster changeover between products.
Real-World Applications for Automated Dissolution
A High Precision Data Acquisition Dissolution System is valuable across many dosage forms. The RT600 handles:
• Oral tablets: Standard basket and paddle methods.
• Patches: Paddle-over-disk with automatic positioning.
• Semi-solid preparations: Using suitable membrane holders.
• Injections: Reconstituted product dissolution.
• API intrinsic dissolution rate (IDR): For early formulation screening.
Each application benefits from the same automation – dosing, sampling, temperature control, and data logging are all hands-off.
Conclusion: Let Automation Work for You
You do not need more technicians or longer shifts to increase dissolution throughput. You need a High Precision Data Acquisition Dissolution System that automates the tedious, error-prone steps. The Raytor RT600 delivers automatic synchronous dosing, automatic positioning, real-time monitoring, infinite storage, and programmable preheating – all in a compact, compliant package.

Quick FAQ
Q: Does the RT600 support 21 CFR Part 11 compliance out of the box?
A: Yes. The High Precision Data Acquisition Dissolution System includes infinite data storage, audit trails, and secure user access – all firmware-level features that simplify Part 11 validation.
Q: Can I use the RT600 for both basket and paddle methods without recalibration?
A: Absolutely. The paddle-basket coaxial design lets you switch between USP Apparatus 1 and 2 without readjusting the dissolution unit height.
Q: How does automatic medium preheating work?
A: You set a start time (e.g., 6:00 AM), and the water bath begins heating automatically. The medium reaches 37.0°C ±0.1°C before your shift begins.
Q: What happens if speed or temperature drifts during a run?
A: The system captures these deviations and will log the incident and potentially alert you so you can address the issue prior to the release of the batch.
Q: Is training needed for operators?
A: Training is minimal. With the RT600, many manual steps are eliminated with automation of dosing, positioning, and preheating. Most operators are productive within one hour.
