NEW - RVA 4800
With the extended temperature range (up to 140°C), the RVA 4800 provides a tool for performing more relevant analysis for a variety of applications, including ingredient (e.g. starch and hydrocolloid) performance under conditions relevant to ultra-high-temperature (UHT) pasteurization of dairy and food products, retorting, pressure cooking, extrusion and other aseptic processing conditions.
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).
High viscosity applications include: extruded and cooked 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 high solids and high viscosity modified starches (e.g. substituted and cross linked cook up food starches).
A fully featured viscometer for analyzing most samples. It covers the mid viscosity range (20 – 8,000 cP at 160 rpm). General purpose applications include: starches and starchy samples, hydrocolloids, proteins, formulated, cooked and extruded foods and “Miniature Pilot Plant” small scale process emulation.
The easy to operate, stand alone (no computer or software required), economical viscometer for routine analysis of most samples. It covers the mid viscosity range (20 – 8,000 cP at 160 rpm). Routine applications include: starches and starchy samples, hydrocolloids, proteins, formulated, cooked and extruded foods, flour and grain quality.
RVA Viscometer Accessories
The Robot Dispenser is an automated sample weigher and dispenser to accompany the Rapid Visco Analyser. Simply scoop sample into an RVA can, and the Robot Dispenser dispenses the correct amount of water into the can.
Sample cans & stirring paddles
Box of 200 cans and paddles in dispenser box for convenient storage and access.
Calibration check starch
Standard test starch ensures that the RVA is operating within specifications in compliance with the principles of Good Laboratory Practice. The test starch is supplied in sachets to maximise shelf life and for convenient storage. (Pack of ten for small users, and a more economical pack of 50.)
NIST calibration check oil
NIST certified oil for monitoring instrument performance and
compliance with calibration to meet the principles of Good
Coated cans & paddles
for broad spectrum resistance
Tests of some types of modified starches, meals and food preparations are best carried out under significantly acid or alkaline conditions, or in the presence of heavy metals. Sicpa Buff coated canisters impart broad spectrum resistance, including at high and low pH, at an economical price.
High Temperature cans & paddles
Tests run at temperatures above 100°C, in the RVA 4800, requires special cans and paddles. A practical tray of 42 high temperature cans and paddles is available.
Published by AACC International, the RVA Handbook helps you to review the scope of applications available, guides you when developing new applications, or improving existing ones, and helps you to interpret RVA test results. With this book you can avoid the pitfalls, get up to speed quickly with your application, and find inspiration for adapting the RVA to new uses.
