The Paltro B2V2 BioTribometer: Precision Tribological Testing for Biomaterials Research
The Paltro B2V2 BioTribometer is a six-station, multidirectional tribological testing platform purpose-engineered for realistic simulation of biomechanical and orthopaedic material wear. Fully compliant with ASTM F732, the internationally recognised standard test method for wear testing of polymeric materials used in total joint prostheses, the B2V2 delivers the motion profile fidelity, load programmability, and long-duration stability required by the world’s most demanding biomaterials research programs.
For research centres, universities, and medical device developers working with orthopaedic implant materials, joint prostheses, antimicrobial coatings, dental biomaterials, cardiovascular device coatings, and next-generation tissue-engineered constructs, tribological performance is a critical and non-negotiable characterisation requirement.
The B2V2 provides the experimental platform to generate the wear data that underpins regulatory submissions, academic publications, and material qualification decisions with a level of motion complexity and throughput that conventional tribometers cannot match.
Multidirectional Motion Profiles Replicating the Complexity of Biological Joints
At the heart of the B2V2 is its multidirectional motion capability. Biological joints do not move in a single plane; they generate complex, multidirectional sliding patterns that produce cross-shear effects recognised as a primary driver of wear in ultra-high-molecular-weight polyethylene (UHMWPE) and other bearing materials used in joint prostheses. Accurately replicating these cross-shear effects in the laboratory is essential for generating clinically relevant wear data.
The B2V2 supports circular, square, linear, lemniscate, U-shaped, and fully user-defined custom motion trajectories, all programmable via the integrated touchscreen interface. Motion frequency is adjustable from 0.5 to 2 Hz with amplitudes up to ±10 mm, giving researchers precise control over the kinematic conditions of their wear simulation experiments.
Six Stations: Synchronised Motion, Independent Loading
The B2V2’s six-station configuration allows up to six specimens to be tested simultaneously, dramatically increasing throughput compared to single-station instruments. All six stations share a common motion drive system, ensuring fully synchronised motion across every specimen throughout the test duration, a critical requirement for inter-specimen comparability within a single experiment.
At the same time, the modular configuration allows independent loading at each station, enabling multi-variable experimental designs where different loads can be applied to different specimens within the same test run. Load profiles are programmable up to 500 N, with support for physiologically relevant gait load cycles alongside fixed loading protocols.
No Pneumatics: Simplified Installation for Any Laboratory
Unlike conventional tribometers that require a pneumatic supply for actuation, the B2V2 operates entirely on standard single-phase electrical power (110–230 VAC, 50/60 Hz). This eliminates the need for compressed air infrastructure, simplifies laboratory installation, reduces ongoing maintenance requirements, and enables flexible placement in any research environment, including university laboratories, hospital research facilities, and medical device company testing suites where pneumatic infrastructure may not be available.
Controlled Test Environments: Temperature, Fluid, and Friction
The B2V2 supports testing in physiologically relevant fluid environments, including bovine serum, saline, and synthetic lubricants, with temperature control up to 50°C via external temperature controller integration and fluid recirculation. This enables accurate simulation of the synovial fluid environment of natural and prosthetic joints, a prerequisite for meaningful characterisation of biomaterial wear.
Optional friction sensor integration extends the B2V2’s capabilities to simultaneous measurement of the coefficient of friction throughout the wear test, delivering richer datasets from every experimental run.
Automation, Monitoring & Data Integrity
The B2V2’s integrated touchscreen control software provides continuous real-time display of test progress, status, and error indicators, enabling confident, unattended long-duration operation. Continuous data acquisition with timestamped traceability ensures a complete, auditable record of every test run, supporting both research publication requirements and regulatory documentation workflows.

Frequently Asked Questions — Paltro B2V2 BioTribometer
Q1: What is a BioTribometer and what does it measure?
BioTribometer is a specialised tribological testing instrument designed to simulate the wear and friction conditions that occur in biological systems, particularly in orthopaedic joint implants, dental prostheses, cardiovascular devices, and other biomedical materials. The Paltro B2V2 BioTribometer measures the wear of biomaterials under controlled motion, load, temperature, and fluid conditions that replicate the mechanical environment of human joints. Key outputs include gravimetric wear (mass loss), volumetric wear, surface topography changes, and, with optional friction sensor integration, coefficient of friction data throughout the test cycle.
Q2: What is ASTM F732 and why is it important for biomaterials testing?
ASTM F732 is the Standard Test Method for Wear Testing of Polymeric Materials Used in Total Joint Prostheses, published by ASTM International. It specifies the equipment requirements, specimen geometry, motion profiles, load conditions, test fluids, and data reporting procedures for standardised tribological evaluation of bearing materials used in joint replacement implants. Compliance with ASTM F732 is required or referenced by regulatory bodies including the US FDA and TGA in Australia when evaluating the safety and performance of orthopaedic implant materials for clinical use. The Paltro B2V2 is designed to comply with ASTM F732 load and motion profiles, making it the appropriate instrument for regulatory-grade biomaterials wear characterisation.
Q3: What motion profiles does the B2V2 BioTribometer support?
The B2V2 supports the following programmable motion profiles: circle, square, line, lemniscate (figure-eight), U-shape, and fully user-defined custom trajectories via the integrated trajectory editor. These multidirectional profiles are critical for replicating the cross-shear effects observed in natural and prosthetic joints, a key factor in accelerating the wear of UHMWPE and other polymer bearing materials that is not captured by simple unidirectional wear tests. Motion frequency is adjustable from 0.5 to 2 Hz, with amplitude up to ±10 mm
Q4: How many specimens can be tested simultaneously?
The B2V2 accommodates six specimens simultaneously across its six test stations. All stations share a common motion drive system, ensuring fully synchronised motion across every specimen in the experiment. Each station can be independently loaded, enabling multi-variable experimental designs. For example, testing different loads on different specimens within the same run. This six-station throughput significantly reduces the time and cost of wear studies compared to single-station instruments.
Q5: What test fluids can be used in the B2V2?
The B2V2 is compatible with bovine serum (the standard lubricant specified in ASTM F732), saline solution, and synthetic lubricants. Testing is conducted in liquid-holding cells that maintain the specimen in contact with the test fluid throughout the test cycle. The external temperature controller option allows fluid temperature to be maintained up to 50°C with fluid recirculation, enabling physiologically relevant test conditions that simulate the thermal environment of the human body.
Q6: Does the B2V2 require a pneumatic supply?
No. Unlike many conventional tribometers and wear testers, the Paltro B2V2 operates entirely on standard single-phase electrical power (110–230 VAC, 50/60 Hz). No pneumatic or compressed air supply is required. This significantly simplifies laboratory installation, eliminates the need for compressed air infrastructure, and reduces ongoing maintenance, making the B2V2 suitable for a wide range of laboratory environments, including university research labs, hospital-based research facilities, and biomedical company testing suites.
Q7: What specimen sizes does the B2V2 support?
The standard specimen configuration for the B2V2 is a pin-on-disc geometry: upper pin of 9 mm diameter and 30 mm length, and a lower disc of 30 mm diameter (45 mm diameter also available). Other sizes and geometries are possible. Contact Radiant Instruments to discuss your specific specimen requirements and confirm compatibility with your experimental protocol.
Q8: Can friction be measured during the wear test?
Yes, with the optional friction sensor integration. When equipped with optional friction sensors, the B2V2 provides continuous coefficient of friction (CoF) measurement throughout the wear test cycle, delivering simultaneous wear and friction data from the same experimental run. This is particularly valuable for research into lubricant performance, surface coating tribology, and the relationship between friction and wear mechanisms in biomaterials.
Q9: Is the B2V2 suitable for long-duration unattended testing?
Yes. The B2V2 is specifically designed for long-duration, high-stability testing. The integrated touchscreen software provides continuous real-time monitoring of test progress, status, and error indicators, with visual alerts if any parameter falls outside acceptable bounds. This enables the instrument to run unattended overnight or over multiple days without operator intervention, a critical capability for the multi-million-cycle wear simulations required by ASTM F732 and orthopaedic implant qualification programs.
