EVU 10 Low Temperature LN2 accessory

The Anton Paar EVU 10 is a liquid nitrogen evaporation unit designed for MCR rheometer temperature devices like the CTD 450 convection oven. It cools samples down to -130 °C or -170 °C, preventing ice formation by flooding the test chamber with nitrogen vapor. Key Features of the EVU 10 System

• Temperature Range: Cools convection ovens down to extreme sub-zero levels (typically -130 °C to -170 °C depending on the specific oven configuration).
• Moisture Control: Floods the measuring area with dry nitrogen gas to stop ice crystal buildup and condensation on cold samples.
• Gap Compensation: Works with the rheometer's normal force control to adjust for thermal contraction of the sample during cooling tests.

IRS Interfacial Rheology System

The Anton Paar Interfacial Rheology System (IRS) is an accessory for MCR series rheometers. It measures two-dimensional flow and viscoelastic properties of liquid-gas or liquid-liquid interfaces. This tool helps evaluate emulsion and foam stability by analyzing how surfactants or proteins behave at phase boundaries.

Key Features

• Compatibility: Works with MCR rheometers (such as the MCR 302 and 502).
• Measuring Geometries: Uses a bi-cone ring, double-wall ring, or Du Noüy ring placed directly at the interface.
• High Sensitivity: Detects very weak interfacial structures using precise low-torque controls.
• Test Modes: Supports rotational and oscillatory tests, including film formation tracking over time.

CTD 620 Convection Temperature Stability Device

The Anton Paar CTD 620 is a high-precision temperature stability chamber and convection oven designed for use with Anton Paar Modular Compact Rheometers (such as the MCR 302) to perform dynamic mechanical analysis (DMA) and high-temperature rheological testing.

Key Features and Specifications

• Function: Provides controlled gas convection heating and cooling around the sample testing area.
• Temperature Stability: Offers high thermal stability within \(\pm0.1\ \text{\textdegree}C\). [1]
• Application Modes: Frequently used in torsion deformation modes for rectangular solid bars, parallel-plate configurations, and melt rheology characterization. [1, 2]
• Environment Control: Often operated under an inert gas purge (such as nitrogen at controlled flow rates around 5 mL/min) to prevent sample degradation or oxidation at elevated temperatures. [1]
• Typical Test Range: Widely utilized for temperature ramps and sweeps spanning ambient values up to high thermal limits (e.g., \(40\ \text{\textdegree}C\) to over \(180\ \text{\textdegree}C\) to \(200\ \text{\textdegree}C\)+) for polymers, composites, and hydrogels

Peltier System P-PTD200/80/I high-precision Peltier temperature control measuring cell 

Provides precise, rapid thermal control—typically ranging from -40 °C to 200 °C (depending on the specific lower plate or cylinder accessory). It eliminates external bath dependencies for standard ranges, features automatic Toolmaster recognition, and supports accurate cone-plate, parallel-plate, or concentric cylinder configurations.

Key Features

• Temperature Range: Standard operation spans from -40 °C up to 200 °C, ideal for polymers, gels, and liquids.
• Toolmaster™: Automatically detects attached measuring systems and lower plate configurations.
• T-Ready™: Verifies that the sample has reached the exact target temperature before data logging begins.
• TruGap™ Support: Adjusts for thermal expansion dynamically during temperature sweeps.

Anton Parr H-PTD200

Peltier-controlled heating and measuring temperature hood designed for use with Anton Paar MCR series rotational rheometer. It pairs with lower Peltier plate systems (like the P-PTD200) to enclose the sample space, providing precise thermal regulation from above and below.

C-PTD200

Peltier-temperature-controlled concentric cylinder device designed for Anton Paar MCR (Modular Compact Rheometer) series instruments. It provides active heating and cooling to accurately control sample temperatures during rheological measurements.

Key Specifications & Features

• Temperature Range: -30 °C to +200 °C

Key Functions and Features

• Precise Temperature Control: Delivers stable thermal management (often within ±0.01 °C accuracy) directly at the measuring zone.
• Evaporation Prevention: Creates a closed thermal chamber that minimizes solvent or sample evaporation during long or elevated-temperature rheological sweeps.
• Purge Gas Option: Can be connected to a gas flow (such as air or nitrogen) to regulate the internal environment or prevent condensation/oxidation at sub-ambient or high temperatures.
• Application Compatibility: Frequently used in cone-plate and parallel-plate configurations for testing polymers, hydrogels, pharmaceutical creams, food emulsions, and dynamic viscosity profiling.
