The Rapid Visco Analyser is a unmatched tool for product development, quality control and process control.
The RVA is a cooking, stirring viscometer with ramped temperature and changeable shear capability perfected for testing the viscous properties of starch, grain, flour and foods. The analyzer requires as little as two or three grams of sample using international standardised methods or your own tailor-made test routines of mixing, measuring, heating and cooling.
Applications include: flour and grain quality, native starches, modified starches and starchy samples, formulated foods (e.g. sauce, ketchup, gravy, dressing, mayonnaise, soup, dairy beverages) other ingredients and foods (e.g. hydrocolloids & proteins), cooked and extruded foods (e.g. ready to eat breakfast cereals, snack foods, pet foods, fish feeds and animal feeds), meltability tests (e.g. process cheese, chocolate and confectionery) and “Miniature Pilot Plant” small scale process emulation.
Rapid Viscosity Profile: Standard starch pasting test in 13 minutes.
Stand-alone option: Preconfigured RVA-StarchMaster2 operates simply; no computer required; no software to learn.
Relevant: Tailor test routines to emulate processing conditions in industry.
The RVA 4500 and RVA-TecMaster combine speed, precision, flexibility and automation with Thermocline for Windows (TCW) software for viscometric data acquisition and analysis on a local machine.
The RVA-StarchMaster2 offers the same speed and precision with simple stand alone operation. The RVA-StarchMaster2 is recommended for routine testing, process and quality control.
Low temperature (LT, below 100°C) aluminium
Made of aluminium (Al 1070 alloy), suitable for most applications at near neutral pH up to 100°C. Also suitable for use with organic solvents such as dimethylsulphoxide (DMSO).
Low temperature (LT, below 100°C) chemical resistant canisters
Coating with a cathodic epoxy to make them chemically resistant to pH (2-11) and are suitable for use for the most severe chemical conditions up to 100°C. The coating narrows the shearing gap between the paddle tip and the canister, which has a minor effect on viscosity results. Using the same cans between tests will ensure consistency in comparisons. Recommended single use only.
High temperature (HT, above 100°C) aluminium
Used with the RVA 4800, for most applications at near neutral pH up to 140°C, including those involving the use of organic solvents such as DMSO.
High temperature (HT, above 100°C) chemical resistant canisters
Coated with cathodic epoxy. Used with the RVA 4800 in extreme pH conditions (2-11) up to 140°C. Recommended single use only.
|Low temperature (LT, below 100°C) standard paddles
Made of (clear) polycarbonate and are suitable for most applications at near neutral pH up to 100°C.
Low temperature (LT, below 100°C) chemical resistant paddles
High temperature (HT, above 100°C) chemical resistant paddles
Variable shear gap paddles – product development
Offset blade paddles – high viscosity fluids
