Accurate pipetting is fundamental to reliable experimental results, yet many laboratories struggle when working with viscous, volatile, foaming, or low–surface-tension liquids. To address these challenges, METTLER TOLEDO Rainin is hosting a live technical webinar titled “How to Optimize Your Pipetting Technique for Challenging Liquids.”
The event will take place on March 3, 2026, at 4:00 PM (London time) and is designed for laboratory professionals seeking practical, actionable guidance to improve accuracy and reproducibility when handling difficult samples.
Why challenging liquids cause pipetting errors
Most standard pipettes are optimized for room-temperature, aqueous solutions, but real-world laboratory samples often behave very differently. Liquids that are viscous, volatile, foaming, hazardous, or have low surface tension can introduce:
- Inaccurate aspiration and dispensing
- Poor reproducibility between operators
- Increased variability across experiments
- Sample loss or contamination
Without adapting tools and technique, even experienced users can obtain inconsistent results.
What the webinar will cover
This live session will explain how liquid properties directly influence pipetting performance and how to adapt both equipment choice and technique to overcome these effects.
Participants will learn:
- How viscosity, volatility, surface tension, and foaming affect pipetting accuracy
- Which pipettes and tips are best suited for different challenging liquid types
- Practical technique adjustments that improve accuracy and reproducibility
- When to use air displacement vs. positive displacement pipettes
- How to match pipetting approaches to specific sample characteristics
The webinar will include clear comparisons between pipetting technologies and demonstrate how small procedural changes can lead to significant improvements in data quality.
Air displacement vs. positive displacement: choosing the right tool
A key focus of the session will be understanding the strengths and limitations of different pipetting mechanisms:
- Air displacement pipettes – widely used and ideal for aqueous samples, but sensitive to temperature, volatility, and viscosity
- Positive displacement pipettes – better suited for viscous, volatile, or hazardous liquids due to direct piston–sample contact
By understanding when and how to use each system, researchers can reduce systematic error and improve confidence in their measurements.
Expert-led instruction
The webinar will be led by Fabian Troll, Global Product Manager at METTLER TOLEDO Rainin. Drawing on extensive experience in liquid handling and laboratory workflow optimization, Fabian will provide hands-on recommendations grounded in real laboratory use cases.
Attendees will also have the opportunity to ask questions live, making this session particularly valuable for those dealing with persistent pipetting challenges.
Who should attend
This webinar is especially relevant for:
- Researchers handling viscous or volatile reagents
- QC and analytical laboratories requiring high reproducibility
- Life sciences, diagnostics, and biopharma professionals
- Anyone experiencing inconsistent results during routine pipetting
Whether you work in research, development, or applied laboratory environments, the session offers clear guidance you can apply immediately.
