Rapid Visco Analyser RVA 4500

Product catalog summary

Overview
The Rapid Visco Analyser (RVA) 4500 is a tool designed to measure the viscosity and performance of starches, raw materials, ingredients, and foods. It uses controlled temperature and shear to optimize quality and performance, suitable for both research and industrial applications.

Features & Benefits

High Sensitivity: Equipped with a direct drive motor for low viscosity samples.
Wide Viscosity Range: Optimized for high viscosity samples.
Rapid Viscosity Profile: Conducts standard starch pasting tests in 13 minutes.
Robust and Traceable: Suitable for various environments with calibration checks to meet ISO standards.
Glass-free and Precise: Safe for food manufacturing with accurate stirring speeds and temperature control.
Standard and Relevant: Approved methods by ICC and AACC International, customizable to industry processing conditions.
ER/ES Compliant: Supports secure electronic records and signatures.

Applications

Starch Testing: Full pasting tests for native and modified starches.
Flour Milling & Baking: Evaluates starch quality and amylase activity for various baked goods.
Proteins and Gums: Analyzes protein concentrates and hydrocolloid formulations.
Brewing and Dairy: Suitable for malting barley and processed cheese manufacturing.

Catalog excerpts

Rapid Visco Analyser Measure Performance of Ingredients and Finished Products

Open the catalog to page 1

The RVA measures the viscosity and performance of starches, raw materials, ingredients and foods using controlled temperature and shear. It can be used to characterize ingredients, intermediates and finished products to optimize quality and performance. Temperature and stirring speed (shear) can be programmed to follow international standard methods or your own custom methods, or use the RVA as a miniature pilot plant to mimic realworld manufacturing and preparation processes such as heating, cooling and mixing. RVA 4500 interfaces with a PC and TCW3 software for operation and data management...
