Revolutionary, all-in-one automatic triaxial testing system integrating the many components of triaxial testing into one, single compact system. Designed to make triaxial testing easier than ever before, the AUTOTRIAXQube will fit neatly in any laboratory and compliment your existing testing capability.

29-WF40Q02: AUTOTRIAXQube – All-in one fully automatic triaxial testing system 110-220V, 50-60Hz, 1ph

Main Features:
  • Space saving: less than one square meter.
  • Easy to install: No need for external panels, tank or hydraulic connection — simply connect the AUTOTRIAXQube to water and power supply and start testing.
  • Fast water de-airing: The built-in vacuum pump, tank, control valves and cavitation system will de-air the water quickly and efficiently down to levels of dissolved air acceptable for triaxial test methods.
  • User-friendly triaxial cell: Integrated lifting system with three internal columns frame makes the triaxial cell easy to handle.
  • Integrated vacuum system: for a streamlined and time saving sample preparation process.
  • Reliable and accurate: Standardized test procedures reduce inconsistencies from operator variables, or other unpredictable external factors.
  • Efficient and repeatable: Complete the whole test, from saturation to failure, in full automatic mode without any interruption — saving time, minimizing operator intervention while increasing accuracy.
  • Versatile and expandable: Start performing permeability testing by adding a third pressure line and advanced measurements such as Bender Element or local strain sensors.

Secure Triaxial Cell Lifting System
The new lifting mechanism allows the operator to raise the cell to its highest position and rotate it through 90 degrees, until it’s safely held in place with a magnetic latch. This removes the need to lift the total weight of the cell while freeing space on the work bench for sample preparation tools.

Built-in Ingenious Hydraulic System
Speeds up the time required to set-up the system correctly (water circuit saturation, pressure system and triaxial cell ) avoiding any possible damage to the sample already positioned in the triaxial cell.

User-friendly Software
The user-friendly optional software and desktop PC allow the operator to control all phases of testing over a fast Ethernet connection. The AUTOTRIAXQube can also connect using Wi-Fi which is useful for remote training and support. If you already use our flexible and renowned AUTOTRIAX software as part of your existing system, there is no need to invest in any additional software as the AUTOTRIAXQube can easily be integrated and controlled as an independent system by your existing PC and software:
  • Effective/total stress: (CU/CAU*, CD/CAD*, UU) (Included in the machine) 
  • Stress path (to be ordered separately) 
  • k0test (to be ordered separately)
* Anisotropic consolidation according to EN 17892:9 is available. For anisotropic consolidation, a vacuum top cap is required.

Universal Accessories Compatibility
All existing accessories already in use with the 70 mm banded triaxial cell (28-WF4070) are compatible with the AUTOTRIAXQube.

Additional Testing with Optional Upgrades
Permeability test, Unconfined test, Bender elements, On Sample
The AUTOTRIAX 2 is an advanced triaxial testing system that can automatically perform up to 6 entire and independent tests at the same time, from start to finish, without any human intervention. The closed-loop feedback control system monitors the components status continuously, in order to react to any change in the parameter pre-set at each test stage.  

Autotriax 2 can perform different kind of triaxial tests:
  • Total and effective stress tests UU (unconsolidated undrained), CU (consolidated undrained) and CD (consolidated drained) isotropic conditions according to ASTM and BS Standards;
  • Stress path tests following MIT and Cambridge methods;
  • K0 anisotropic volume controlled tests;
  • Permeability tests in triaxial cells according to BS 1377: 6;
  • Unsaturated soil triaxial test with control of matric suction using the axis translation method.

Also, additional software package available on request for performing:
  • CRS – Constant Rate of Strain
  • Hydraulic consolidation
  • Unconfined compression
  • CBR (California Bearing Ratio)

A typical PC controlled fully automatic triaxial configuration includes:

Load frame:
TRITECH 50 kN or 100 kN: TRITECH original high-performance load frames for triaxial tests, ideal solution for advanced and research laboratories that want to perform high quality tests at high productivity levels, directly managed by data acquisition and control unit. 

Triaxial cell with accessories:
The proper model can be selected from our range (see triaxial load frame TRITECH  and triaxial cells for advanced applications or  double wall triaxial cells required for unsaturated tests) or, as alternative, existing machines can be used.

Data acquisition and control unit:
Data acquisition and control unit transmitting data and information between the software and all the active components, such as pressure controllers and Tritech triaxial load frame.

Pressure/volume controller:
Four models are available depending on: max pressure capacity (3500 or 1700 kPa) and number of pressure lines (one or two).

Triaxial test automatic control and processing software:
The AUTOTRIAX 2 software is a comprehensive and user-friendly interface between the operator and the testing system.
