Brookfield CTX Texture Analyzer

Overview

The Brookfield CTX Texture Analyzer is a high-precision, dual-mode mechanical testing instrument engineered for objective, quantitative measurement of textural and mechanical properties of soft solids, semi-solids, and viscoelastic materials. Based on controlled-force compression and tension actuation via a precision stepper motor-driven crosshead, the CTX operates on fundamental principles of uniaxial mechanical deformation—applying defined loads at regulated speeds to generate force–distance or force–time profiles. Its architecture adheres to standard test methodologies including compression (e.g., puncture, extrusion, hardness), tension (e.g., peel, tensile strength, adhesion), and shear (e.g., spreadability, cutting). Designed for integration into regulated laboratory environments, the CTX delivers repeatable, traceable results essential for method validation, product development, and routine quality control across food, pharmaceutical, cosmetic, and packaging industries.

Key Features

• Dual-mode operation: Simultaneous support for compression and tensile testing without hardware reconfiguration—enabling rapid transition between probe-based penetration (e.g., TA-44 spherical probe) and fixture-mounted peel/tensile tests (e.g., 90° peel jig, tensile grip set).
• High-resolution load cell: Capable of measuring forces from 0.01 N up to 500 N with ±0.5% full-scale accuracy, ensuring sensitivity for delicate samples (e.g., yogurt film integrity) and robustness for high-force applications (e.g., cheese firmness or tablet crushing).
• Programmable crosshead speed: Adjustable range from 0.01 mm/s to 10 mm/s in 0.01 mm/s increments, facilitating compliance with standardized test protocols such as ASTM F3102 (peel rate: 300 mm/min) or USP (tablet hardness: 1–2 mm/s).
• Modular probe and fixture system: Compatible with over 60 ISO- and ASTM-compliant accessories—including Kramer shear cells, Volodkevich bite jaws, and texture-specific probes—enabling method transfer across laboratories and alignment with published reference methods.
• Integrated thermal enclosure option: Optional temperature-controlled chamber (−10 °C to +60 °C) supports rheo-textural characterization under realistic storage or consumption conditions (e.g., ice cream consistency at −5 °C or chocolate snap behavior at 25 °C).

Sample Compatibility & Compliance

The CTX accommodates diverse sample geometries and physical states—from viscous dairy products (yogurt, custard), elastic confectionery (gummy bears, marshmallows), compressed pharmaceutical tablets, cosmetic sticks (lipstick, deodorant), to laminated packaging films. All test configurations are designed to meet international regulatory expectations: force calibration traceable to NIST standards; data acquisition compliant with FDA 21 CFR Part 11 requirements when used with validated TexturePro CT software (including electronic signatures, audit trail, and user access controls); and documentation support for ISO/IEC 17025 accreditation. Routine verification using certified reference standards (e.g., calibrated spring kits, polymer modulus standards) ensures ongoing measurement integrity across shifts and operators.

Software & Data Management

TexturePro CT software provides an intuitive, Windows-based interface for test method creation, real-time visualization, and post-acquisition analysis. Users define multi-stage test sequences (pre-test equilibration, trigger threshold, return-to-start), apply mathematical derivatives (e.g., slope of force curve = stiffness; area under curve = work of deformation), and generate comparative statistical reports (mean, SD, CV%, ANOVA). Raw data exports to CSV, Excel, and PDF formats support seamless integration into LIMS, ELN, or enterprise QA systems. Audit trails record operator ID, timestamp, parameter changes, and result modifications—fully satisfying GLP and GMP documentation requirements for regulated environments.

Applications

• Food Science: Quantifying firmness of baked goods, cohesiveness of meat analogs, spreadability of margarine, gumminess of chewing gum, and peel strength of fruit snack films.
• Pharmaceuticals: Measuring tablet hardness (USP ), capsule shell rupture force, gelatin bloom strength, and transdermal patch adhesion per ISO 2528.
• Cosmetics: Evaluating lipstick break resistance, mascara film flexibility, and foundation spread coefficient using controlled shear fixtures.
• Packaging: Validating seal integrity of pouches (ASTM F88), opening force of child-resistant caps (ASTM D3475), and delamination resistance of multilayer laminates.

FAQ

Is the CTX compatible with existing Brookfield accessories?
Yes—the CTX accepts all legacy Brookfield texture probes and fixtures designed for the QTS and TA.HD Plus platforms, enabling cost-effective method migration and hardware reuse.
Does the system support automated pass/fail criteria for QC release?
Yes—TexturePro CT allows users to define upper/lower specification limits per parameter (e.g., “hardness ≥ 8.5 N, ≤ 12.0 N”) and auto-flag outliers during batch testing.
Can test methods be locked to prevent unauthorized modification?
Yes—administrator-level password protection enables method lockdown, ensuring procedural consistency across shifts and operators.
What calibration services are available?
Brookfield-certified field service engineers provide on-site annual calibration with NIST-traceable documentation, including load cell linearity verification and crosshead position repeatability assessment.
Is training included with purchase?
Standard installation includes one-day on-site operator training covering safety, method setup, data export, and basic troubleshooting—plus access to Brookfield’s global eLearning portal with video modules and SOP templates.
