ABOUT ULTRA SCIENTIFIC
ULTRA Scientific, Inc. is a global leader in analytical chemical solution manufacturing, offering certified reference materials,
QC standards, reagents and other laboratory solutions to meet the needs of laboratory professionals world-wide. Founded
in 1976, ULTRAs corporate headquarters is in North Kingstown, RI and operates sales offices and distribution centers in
Bologna, Italy and Wesel, Germany.
ULTRAs extensive catalog listing of chemical standards is complemented by our flexibility to manufacture custom
solutions to exacting specifications. We sell products and services direct to end-user laboratories, through international
and regional distribution, and under OEM partnerships with multinational instrument manufacturers.
Omnion Scientific Instruments (OSI), as a wholly-owned subsidiary of ULTRA Scientific, manufactures chemical standards,
reagents and 123 Ion Selective Electrode Meters for the measurement of sodium, chloride, potassium and calcium
content in food, beverage, feed and grain. In addition, ULTRA manufactures a line of Oxidative Stability Instruments to
analyze the stability of biodiesel, oils, fats, fat substitutes, plastics and cosmetics.

THE OSI PROGRAM
THE OIL STABILITY INDEX
Continuous data monitoring
Definition: All oils and fats have a resistance to oxidation which depends on the degree of saturation, natural or added antioxidants,
prooxidants or prior abuse. Oxidation is slow until this resistance is overcome, at which point oxidation accelerates and becomes very rapid. The
length of time before this rapid acceleration of oxidation is the measure of the resistance to oxidation and is commonly referred to as the induction
period, or Oxidative Stability Index.
Measure up to 24 channels simultaneously
Automatic endpoint determinations
The Omnion Oxidative Stability Instruments provide an instrumental determination of the oxidative stability of fats oils and other organic materials, eliminating the time, inconvenience, hazards and errors associated with manual titrations. Continuous data monitoring (up to 24 channels
simultaneously) ensures no missed endpoints.
Graph data; current or historical
Store, recall, overlay complete OSI curves for exact
batch-to-batch comparisons
Shelf Life/Predictive Value
The Omnion OSI accelerates the development of oxidative rancidity so that the useful life of an oil containing material may be determined.
Unlike tests such as peroxide value, which determine oil quality only at the time of the test, the OSI has predictive value, therby allowing
quality decisions to be made before spoilage becomes a problem.
Conversion algorithms
a) O
SI/OSI converts OSI at one temperature to OSI at any
other temperature
b) OSI/AOM converts OSI to 97.8 C AOM
c) AOM/OSI converts AOM to OSI at any temperature
The OSI is an invaluable quality control tool for eliminating inferor ingredients, for isolating process variables causing stability problems, for measuring the stability of finished products, for evaluating antioxidant activity, for monitoring the deterioration of cooking oils with use, for determining
the stability of PVC, and for many other applications where oxidative rancidity is the cause of product failure. Because the OSI has predictive value,
problems are detected and eliminated before they cause rejection, unlike other tests which merely indicate that problems have occurred after it is
too late to correct them.
Instrument status obtained at a keystroke allows
status of all channels to be simultaneously examined
Current data is immediately displayed on all channels
Designed for precision and accuracy, ease of use and maintenance, and inexpensive operation, the OSI is used worldwide by refineries, food companies, pharmaceutical concerns, research institutes, chemical firms, pet food manufacturers, universities and governments agencies.
OSI CONFIGURATION
THE OSI ADVANTAGE
EASY TO USE | SIMPLE TO MAINTAIN | NO MOVING PARTS | NO CHEMICALS | UNBREAKABLE SENSORS
Excellent precision
Continuous data monitoring
ensures no missed endpoints
Automatically calculates induction times
and plots conductivity/time curves
