Brandtech Pipette Leak Tester

Discover and Eliminate Pipette Leaks with the BRAND PLT Unit
– Precision You Can Rely On

The most common cause of inaccuracies in piston-operated pipettes is leakage, often caused by damage to seals, pistons, or tip cones. These leaks, invisible to the naked eye, lead to significant volume errors that compromise your results. The BRAND Pipette Leak Tester (PLT Unit) detects even the smallest leaks within seconds, ensuring your pipettes maintain peak performance.

Why Pipette Leak Detection Matters

Air-displacement pipettes require regular checks to comply with ISO 8655-2 error limits, yet traditional calibration certificates only reflect the instrument's accuracy at the time of testing. Leaks can occur at any moment, meaning errors could arise between scheduled calibrations. Alarmingly, over 80% of pipettes sent in for repair have undetected leaks and operate outside volume tolerances—even if they don’t drip.

The PLT Unit bridges this gap, providing quick, reliable daily checks that complement regular gravimetric testing. Early leak detection ensures consistent accuracy and improves process reliability.

How the BRAND PLT Unit Works

The PLT Unit uses differential pressure measurement to detect and quantify leaks. By creating negative pressure, the unit measures pressure rise over time, calculating the leak rate.

Key Features of Leak Detection:

• Leak Rate Measurement: Factors like pipette/tip dead volume, cross-section flow, and pipette type are considered for precise results.
• pV Value Calculation: Determines gas volume loss over time in hPa ml/s for accurate detection.

For example, a leak rate of 1 hPa ml/s at atmospheric pressure (1000 hPa) indicates a volume loss of approximately 1 µl/s.

Intuitive Design for Easy Operation

The PLT Unit’s menu-driven software and user-friendly jog wheel make setup and testing simple. Users can easily adjust test parameters, select pressure units, and choose between English, Spanish, or German language options.

Diagnostic Tools for Comprehensive Testing

With the PLT Unit, you can:

• Test the entire pipette system with mounted, unused tips.
• Identify leaks in specific areas by retesting without the tip.
• Perform static or dynamic testing to pinpoint the source of leaks.
• Test multichannel pipettes up to four channels at a time, streamlining your workflow.

Pass/Fail Testing for ISO Compliance

The PLT Unit references ISO 8655-2 tolerances to determine whether your pipette is within acceptable limits. By calculating leak volumes based on over 35 years of pipette development expertise, the PLT ensures your instrument meets the highest standards.

Benefits of the BRAND PLT Unit:

• Accurate Leak Detection: Finds even microscopic leaks to maintain pipette reliability.
• Process Efficiency: Saves time with fast results and multichannel testing capabilities.
• Compliance Assurance: Supports adherence to ISO 8655-2 standards between calibrations.

Invest in the BRAND Pipette Leak Tester to enhance your lab's accuracy, reliability, and productivity. With the PLT Unit, you can safeguard your air-displacement pipettes from undetected leaks and ensure consistent, precise results.
