The new RheoTex software developed by LAMY RHEOLOGY allows control of all instruments

The measuring head of the GT300 PLUS has the same characteristics as the GT300 PLUS viscometer.
Like this one, it can be used alone or with the Rheotex Software.
When it is controlled by a computer, the choice of the most judicious method is a constant speed measurement followed by the evolution of the viscosity as a function of time (see instructions for use of the software for programming).
This will determine the inflection point when the reaction of your product begins.
Using the GT300 PLUS without the software only provides the time when the maximum torque of the instrument is reached.
Since it is an automatic shutdown, no recording or reading of the result will be possible.
It is therefore best to use it with the software.
When using the GT300 PLUS with or without software, the measurement will stop automatically when the maximum torque of the measuring head is reached.

The license file associated with the software allows you to automatically configure software to be compatible with instrument. Since the software base is the same,
only an additional license is required when you have two devices to control by RheoTex.
The installation of the software is not limited to one computer station.
The integrity of results and methods is guaranteed by using a database and by an optimized management of the users with specific rights.
New graphical tools allow custom management of the display of curves, tables and analysis results.
The 21 CFR option is available in two versions :
• Standard for only one approval electronic signature.
• Advanced for three level of electronic signature : Done-Review-Approval.

  • Creation and saving of methods.
  • Transfer data from device memory.
  • Temperature ramp method.
  • Use of mathematical tools for data analysis.
  • Creation of free program.
  • PDF report editing.
  • Compatible with office software or experience creation (automatic measurement and analysis).
  • 21 CFR Part 11 Compatible.
Manual  Mode  enables  to  choose  your  measurement  parameters  like «Measuring System », « Speed » then « Time of measurement ».

Auto mode allows you to select pre-recorded programs.
Select the program from the list and click "Start" to start your measurement.
The display automatically adjusts to show the current measurement.
At the end of measurement, instrument will ask you to save or print (if printer is connected).

Remote Mode
This mode enables to drive GT300 PLUS by external RheoTex software.

This barcode reader allows you to quickly identify your sample without risk of data entry errors. It is compatible with all instruments in the LAMY RHEOLOGY range thanks to  their USB port and with RHEOTEX software when connected to the computer.
Included USB cable and holder.

(Ref. 111-000630)

The screen protector provides permanent protection for touch screen of instruments in the LAMY RHEOLOGY range.
It is effective against projections and dust while  ensuring ease of use.
GEL TIMER GT 300 PLUS is the solution to works from 0.05 to 30 mNm

Unlimited number of speeds between 0.3 and 1500 rpm

Regarding the choice of rotation speed, the ideal range is between 0.5 and 20 rpm.
Too slow a speed at the beginning of the measurement can cause problems of too low torques and a too fast speed of the couples too high when the reaction of your product accelerates.
The choice of speed will depend on the kinetics of your product.
