Performance examples & technical parameters
Representative accuracy/precision examples (values in % and absolute μl):

Single-channel adjustable (examples)
0.1–2.5 μl (inc. 0.05 μl): test 2.5 μl — systematic 2.50% (0.0625 μl) / random 2.00% (0.05 μl)
0.5–10 μl (inc. 0.1 μl): test 10 μl — systematic 1.00% (0.1 μl) / random 0.80% (0.08 μl)
10–100 μl (inc. 1 μl): test 100 μl — systematic 0.80% (0.8 μl) / random 0.15% (0.15 μl)
1000–5000 μl (inc. 50 μl): test 5000 μl — systematic 0.50% (25 μl) / random 0.15% (7.5 μl)

8- and 12-channel adjustable (examples)
0.5–10 μl (inc. 0.1 μl): test 10 μl — systematic 1.50% (0.15 μl) / random 1.50% (0.15 μl)
5–50 μl (inc. 0.5 μl): test 50 μl — systematic 1.00% (0.5 μl) / random 0.50% (0.25 μl)
50–300 μl (inc. 5 μl): test 300 μl — systematic 0.70% (2.1 μl) / random 0.25% (0.75 μl)

Fixed-volume examples
5 μl — syst. 1.3% (0.065 μl) / rand. 1.2% (0.06 μl)
100 μl — syst. 0.5% (0.5 μl) / rand. 0.3% (0.3 μl)
1000 μl — syst. 0.3% (3.0 μl) / rand. 0.2% (2.0 μl)

Applications & buyer guidance

• Choose single-channel adjustable models for variable-volume workflows; use multichannel 8/12 for plate-based high-throughput tasks
• Verify required accuracy/precision per working volume against the technical tables when selecting a model
• Lower part autoclavable and modular piston/tip assemblies simplify maintenance and compliance workflows
