Anton Paar PTD 100 Cone-Plate Temperature-Controlled Rheology Accessory for ViscoQC 100/300

Overview

The Anton Paar PTD 100 Cone-Plate is a precision-engineered temperature-controlled rheological accessory designed exclusively for integration with the ViscoQC 100 and ViscoQC 300 rotational viscometers. It transforms these benchtop instruments into high-accuracy cone-and-plate viscometers—enabling absolute viscosity measurement under controlled shear conditions defined by ISO 2555 and ASTM D2196. The system operates on the fundamental principle of controlled-gap rotational rheometry: a precisely ground conical geometry rotates above a flat plate, generating a uniform shear rate across the sample volume. This geometry eliminates end-effects and ensures Newtonian and non-Newtonian fluid behavior is quantified with high reproducibility—critical for QC labs validating formulation consistency, thermal stability, or shear-thinning profiles. Its integrated Peltier-based temperature control delivers stable, programmable thermal regulation from 0 °C to 100 °C (±0.1 °C accuracy), eliminating reliance on external water baths and reducing setup complexity.

Key Features

• Integrated Peltier temperature control (0–100 °C) with real-time monitoring and closed-loop feedback via ViscoQC touchscreen interface
• Toolmaster™ automatic identification and parameter recall: eliminates manual input errors and reduces setup time by up to 25 seconds per measurement
• Electromagnetic coupling mechanism ensures rapid, repeatable, and backlash-free attachment to ViscoQC spindle drive
• Auto-gap setting function: fully automated, motorized gap adjustment to the nominal 0.05 mm cone-plate clearance—unique at this performance tier
• Optimized for minimal sample volume: accurate viscosity determination using only 0.5 mL of liquid—ideal for precious, hazardous, or low-yield formulations
• Conical geometry conforms to ISO 3219 and DIN 53019 standards for cone-and-plate rheometry; certified angular tolerance ≤0.1°

Sample Compatibility & Compliance

The PTD 100 supports aqueous, organic, polymeric, and suspension-based liquids—including paints, inks, pharmaceutical suspensions, food emulsions, and cosmetic gels. Its stainless-steel cone (standard 25 mm diameter, 2° angle) and hardened steel plate resist corrosion and wear during routine QC use. The system complies with GLP and GMP documentation requirements when used with ViscoQC’s audit-trail-enabled firmware (supporting 21 CFR Part 11–compliant user access controls and electronic signatures). Measurement traceability aligns with ISO/IEC 17025 calibration practices; factory calibration certificates include uncertainty budgets referenced to NIST-traceable standards.

Software & Data Management

All temperature setpoints, rotational speeds, torque values, and viscosity results are managed natively within the ViscoQC operating system—no additional software license required. Data export is supported in CSV and PDF formats, including metadata (date/time, operator ID, instrument serial number, temperature log, and gap verification timestamp). The system logs full thermal ramp history and maintains a secure, tamper-evident measurement archive compliant with internal QA protocols. Optional connectivity via Ethernet or USB enables centralized data aggregation into LIMS environments supporting ASTM E1578 and ISO 15197 interoperability frameworks.

Applications

• Quality control of low-viscosity solvents and high-shear-rate coatings where traditional spindle geometries yield insufficient sensitivity
• Thermal viscosity profiling of thermosensitive biologics (e.g., monoclonal antibody formulations) across physiological and storage temperature ranges
• Routine validation of batch-to-batch consistency in adhesive, ink, and resin manufacturing per ISO 2555 acceptance criteria
• Stability assessment of nanoemulsions and colloidal dispersions under controlled thermal stress
• Regulatory submission support for FDA IND/ANDA filings requiring documented, temperature-resolved rheological characterization

FAQ

Is the PTD 100 compatible with ViscoQC 200 models?

No—the PTD 100 is certified only for ViscoQC 100 and ViscoQC 300 platforms due to mechanical interface and firmware protocol requirements.
Does the system require recalibration after each temperature change?

No—thermal drift compensation is embedded in the Peltier controller firmware; factory calibration remains valid across the full 0–100 °C range.
Can the gap be manually adjusted?

No—gap setting is fully automated and locked post-calibration to ensure geometric fidelity; manual intervention voids metrological validity.
What is the maximum measurable viscosity range with this accessory?

Viscosity range depends on selected rotational speed and sample rheology; typical operational span is 1 mPa·s to 10⁵ mPa·s under standard test conditions (25 °C, 1–100 rpm).
Is Toolmaster™ data stored permanently on the device?

Yes—Toolmaster™ configuration files, including geometry ID, calibration coefficients, and thermal offset tables, are retained in non-volatile memory even after power cycles.
