RVA 4500, 230V, 50/60 Hz with TCW S/W

The best choice for analyzing low viscosity samples (down to 10 cP at 160 rpm) because of its exceptional sensitivity and accuracy. Low viscosity applications include: low solids starches (e.g. ethylated & cationic starch for paper & packaging), low viscosity food starch (e.g. acid/enzyme thinned), low viscosity products (e.g. sauce, ketchup, gravy, dressing, mayonnaise, soup, dairy beverages) and other low viscosity non starch foods (e.g. with hydrocolloids & proteins). Also optimized for the widest viscosity range (up to 25,000 cP at 160 rpm).

Overview

The Rapid Visco Analyser is a unique tool for product development, quality and process control and quality assurance. The RVA is a cooking, stirring viscometer with ramped temperature and variable shear capability optimized for testing the viscous properties of starch, grain, flour and foods. The instrument will analyze as little as two or three grams of sample using international standard methods or your own tailor-made test routines of mixing, measuring, heating and cooling.

Applications include the following:

  • 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)
  • "Miniature Pilot Plant" small-scale process emulation

The new RVA 4800 can perform regular tests below 100°C, as well as high-temperature tests up to 140°C in a specially designed pressure vessel.
