Optigraph: control your rennet and determine the ability of milk to coagulate
Widely used by dairy industries, both in Research as well as Quality control, Optigraph allows you to better monitor your process (Milk standardisation, milk quality…).
Developed in partnership with the INRA (LGMPA / G. CORRIEU) by Alliance Instruments, on the request of ARILAIT, who was looking for a new type of analyzer to replace the old and obsolete technology from the Formagraph. The selected solution is a simple system, fully automated, and dedicated to simultaneous control of coagulation of 10 milk samples: the Optigraph.
Based on the measurement of Near Infrared signal, the Optigraph makes the calculation in real time of all the parameters required for the process: coagulation time, firmness evolution, optimum curd cutting time, organization speed.
Zero maintenance, time saving, easy cleaning
Optigraph has no moving parts. 10 curves on the same graph
The Optigraph facilitates reading and gives in real time curves and results. You will not only save the use of consumables (thermic paper…) but be able to print and save all your results.
The Optigraph has also been designed to reduce the time of daily cleaning of parts and to keep stable and reliable results during its entire lifetime. Just a simple cleaning of the cuvette after each analysis, and you can focus on your analysis, being sure that you will keep reliable and accurate results for years.
The most complete information
Easy software to drive the instrument and get your results
- Automatic calibration before each test
- Personalization of all feature points.
- Control of temperature from 25° up to 45°C
- Graphical representation of data:
- Classical curves (glass of Champagne)
- All curves in one
- Firmness evolution
- Speed (1st derivative of signal)
- Storage of old data on hard disk to create a ‘library’ for traceability
- Storage of the temperature measurement
The software will give you different type of graphs allowing you to characterize each sample independent of the type of milk you are measuring (cow, goat ,sheep ,buffalo…). Also by saving the raw signal Optigraph enables you to print, export, or save all data you need to rework them as you like.
