Choosing the Right Pipette for Precision: Tips from Sartorius & BRAND Experts

Whether you’re performing delicate molecular assays or routine liquid transfers, your pipette is one of the most essential instruments in the lab. Selecting the right model—manual or electronic, single- or multi-channel—directly impacts your accuracy, efficiency, and comfort.

This comprehensive guide explores how to choose the right pipette for your workflow, the differences between leading brands like Sartorius, BRAND, and Thermo Scientific, and expert tips to maintain long-term accuracy.

At LabFriend, you’ll find a wide range of pipettes and accessories sourced from trusted manufacturers—helping scientists, educators, and technicians achieve precision with every drop.

1. The Role of Pipettes in Modern Laboratories

Pipettes are indispensable tools in any lab—used to measure and transfer precise liquid volumes. From simple chemical assays to advanced genetic research, pipettes ensure reproducibility across experiments.

A high-quality pipette doesn’t just deliver accuracy; it also minimises user fatigue and prevents repetitive strain injuries (RSIs). Ergonomic design, calibration stability, and compatibility with quality tips are key factors that distinguish a premium pipette from an average one.

2. Types of Laboratory Pipettes

2.1 Air-Displacement Pipettes

The most common type found in research and diagnostic labs. These pipettes use an air cushion between the piston and liquid to aspirate and dispense volumes accurately.

Applications: Routine molecular biology, clinical testing, reagent preparation.

Best examples:

• BRAND Transferpette® S Pipette – high accuracy, lightweight body, and colour-coded controls.

• Sartorius Tacta® Pipette – superior ergonomics with a perfectly balanced design.

2.2 Positive-Displacement Pipettes

Used for viscous, volatile, or high-density liquids (like oils, glycerol, or solvents) that challenge air-displacement models. The piston directly contacts the liquid, ensuring leak-free dispensing and maximum precision.

Examples:

• BRAND HandyStep® Touch – electronic stepper for serial dispensing.

• Sartorius Microman® E – exceptional control for small-volume and high-viscosity samples.

2.3 Single-Channel vs Multi-Channel Pipettes

• Single-Channel Pipettes: Ideal for individual sample handling in analytical or research applications.

• Multi-Channel Pipettes: Designed for high-throughput work, such as microplate assays or ELISA tests.

Examples:

• Sartorius Picus® NxT Electronic Pipette (8- or 12-Channel) – precise, lightweight, and digitally controlled.

• BRAND Transferpette® Multi-Channel – robust construction and quick-set volume adjustment.

2.4 Electronic Pipettes

For labs needing precision, repeatability, and time savings, electronic pipettes are invaluable. They minimise manual error and allow programmable functions such as multi-dispensing, dilution, and mixing.

Highlights:

• Sartorius Picus® NxT – compact electronic pipette with intuitive digital interface.

• Thermo Scientific E1-ClipTip™ Electronic Pipette – ensures consistent tip sealing with clip-lock technology.

3. How to Choose the Right Pipette

3.1 Volume Range and Accuracy

Select pipettes with volume ranges suitable for your routine tasks. For example:

• 0.1–2.5 µL for PCR and molecular work.

• 10–100 µL for general assays.

• 100–1000 µL for media or buffer preparation.

Always choose a pipette where your target volume lies in the mid-range of its capacity for maximum precision.

3.2 Ergonomics and Comfort

Fatigue can severely affect accuracy. Ergonomically designed pipettes from Sartorius and BRAND feature lightweight builds, soft-touch plungers, and low pipetting forces to enhance comfort during repetitive use.

Expert Tip: Sartorius pipettes are engineered to maintain natural wrist posture, reducing repetitive strain injuries—a vital feature in high-throughput labs.

3.3 Compatibility with Pipette Tips

A pipette’s accuracy depends heavily on the fit and quality of tips. Poor sealing can cause air leaks and imprecise volumes. Using brand-specific tips—like BRAND TipBox®, Sartorius Optifit, or Thermo Scientific ClipTip™—ensures a perfect seal and consistent results.

3.4 Calibration and Maintenance

Regular calibration safeguards your data integrity. Pipettes should be calibrated at least twice yearly or after extensive use.
Key maintenance practices:

• Clean pistons and seals regularly.

• Store vertically using a pipette stand.

• Avoid dropping or immersing the body in liquid.

LabFriend also supplies replacement seals, lubricants, and calibration accessories from major brands to keep your instruments in peak condition.

4. Comparing Leading Pipette Brands

Sartorius Pipettes

Sartorius is a global leader in precision liquid handling, known for ergonomic innovation and durability. Their Picus® NxT and Tacta® models set industry benchmarks for lightweight performance and digital precision.

• Electronic control options for repetitive tasks.

• ISO 8655-compliant for measurement accuracy.

BRAND Pipettes

German-engineered BRAND pipettes are synonymous with reliability and comfort. Their Transferpette® line delivers robust performance across teaching, research, and clinical labs.

Key Features:

• One-handed operation and easy volume adjustment.

• Air-cushion technology for smooth aspiration.

• Autoclavable lower parts for simple sterilisation.

• Colour coding for intuitive volume identification.

Thermo Scientific Pipettes

Thermo Scientific combines innovation with rugged design, ideal for intensive lab environments. Their Finnpipette™ and ClipTip™ series are popular across Australian research institutions.

Key Features:

• Secure tip attachment with minimal ejection force.

• Durable materials for chemical resistance.

• Smooth operation with precise plunger control.

5. Best Practices for Reliable Pipetting

Accuracy in pipetting is not only about the device—it’s about technique.
Follow these best practices to ensure consistency:

• Pre-wet tips before use to stabilise temperature and humidity.

• Keep pipettes vertical when aspirating.

• Dispense slowly along tube walls to prevent splashing.

• Avoid pressing the plunger too hard—it can distort results.

Even the most advanced pipettes need careful handling. Incorporating good pipetting habits ensures reliable performance and longer instrument lifespan.

6. Why Premium Pipettes Are Worth the Investment

High-quality pipettes from Sartorius, BRAND, and Thermo Scientific come with advanced calibration mechanisms, durable construction, and precision-engineered tips.

While cheaper models may appear cost-effective initially, they often lead to inconsistencies, calibration drift, and user fatigue. Premium pipettes offer:

• Consistent accuracy across thousands of cycles.

• Lower maintenance and repair costs.

• Improved user comfort and compliance with ISO standards.

Over time, a dependable pipette becomes a long-term investment in laboratory efficiency and data quality.
