BROOKFIELD _ VISCOMETERS / RHEOMETERS RST Touch Series Rheometers ™ Touch Screen Rheometers for Controlled Rate/Stress Measurement The RST series of touch screen rheometers represent the best that Brookfield has to offer — instruments that operate both in controlled shear rate (rpm) and controlled shear stress (torque) modes — for sophisticated rheological analysis. With automatic data collection and analysis using optional Rheo3000 software, RST Rheometers offer greater flexibility and more features than other high-end rheometers in their class — at a fraction of the cost. RST Rheometers have a durable design with rapid bob (spindle) attachment and easyto-clean surfaces for years of trouble-free operation. Increased measurement capabilities range from simple single-point viscosity tests to comprehensive rheological profiling. Evaluate material behavior from initial yield stress through full flow curve response at variable shear rates to relaxation, recovery and creep. The RST touch screen series is available in three configurations and all models feature: - Controlled stress/rate operation to analyze comprehensive flow behavior - User friendly LCD touch screen with graphical display - 11 memory slots for structured multi-step test programs ADHESIVES: RST-CPS tests a variety of silicone-based adhesives at temperatures in excess of >200°C. Advantages include small sample volume (< 2mL), rapid temperature equilibrium with Peltier plate, variable shear rate (to 7,800 sec-1) to duplicate conditions for actual adhesive use, quick test time (< 2 min). ADHESIVE INGREDIENTS: RST-CPS with Peltier control excels at rapid QC measurements at defined shear rates. Optional Peltier plate changes temperature much more quickly than bath/circulator. Test throughput increases dramatically. BIOMASS: RST-CC with vane spindle in coax chamber measures biomass fluids used for biofuel production. Easily handles suspended solids and evaluates important flow properties by simulating what happens to the material during pumping in production. CHOCOLATE: RST-CC is instrument of choice for select manufacturers who run 24/7 operations requiring robust, reliable performance. Choice of optional serrated bob (spindle). Conforms to DIN and ISO test methods which quantify yield stress and consistency using Casson analysis. Affordable alternative to higher priced rheometers. DAIRY: RST-CC with double-gap geometry measures low viscosity (<0.1 Pa•s) dairy products ranging from skim milk to thicker creams. GYPSUM: RST-SST is popular choice for measurement of joint compound manufactured by the gypsum industry in accordance with ASTM C474. Small footprint, data display in BU units, and robust design make it ideal for lab and production floor use. PESTICIDES: RST-CC with double-gap geometry measures various low viscosity formulations (0.001 Pa•s) at shear rates up to 5,600 sec-1. Provides reliable capability in a busy QC lab measuring dozens of samples each day. - Auto spindle identity recognition PHARMACEUTICAL: RST-CPS with open plate design for easy sample placement accommodates a variety of small sample sizes (< 4mL) and rapid temperature control using the Peltier option. Produces quick profiling of flow behavior, including yield stress and creep, important properties for characterizing ointments. - Quick connect coupling for easy spindle attachment - Optional Rheo 3000 Software for PC control and data management - 21 CFR compliance for controlled user access and data security A portable version without touch screen capability (Model RS Portable) is also available. RST Technical Specifications (all models) Maximum Torque: Torque Resolution: Speed: Data Output: Display Units: Some popular applications include: PIGMENT DISPERSIONS: RST-CPS with Peltier is used by a range of industrial markets, including plastics and paints. Handles broad viscosity range from thin formulations (0.025 Pa•s) to non-flowing pastes. Broad shear rate capability simulates both processing of materials (pumping and mixing) and application of material (brushing and spraying). SAUCES AND SYRUPS: RST-CPS with Peltier replaces traditional hour-long viscosity tests which measure product from a cooking vessel after it cools to room temperature. Peltier option cools sample to 25°C in less than 1 minute, greatly reducing test time. SLUDGE/SLURRIES/CONCRETE: RST-SST with vane spindle geometry measures diverse mixtures with particulates ranging in concentration up to 70% solids. www.brookfieldengineering.com www.brook
