qPCR Sample Preparation

The TopPette 12-Channel Adjustable Manual Pipette is a high-performance multichannel pipette engineered for accuracy, reproducibility, and operator comfort in ultra-high-throughput clinical diagnostics, molecular biology, and pharmaceutical research. Available in four volume ranges from 0.5 µL to 300 µL, this 12-channel pipette allows simultaneous transfer of liquids across an entire column of a 96-well plate (8 dispenses per plate) or across an entire row of a 384-well plate (16 dispenses per plate), reducing pipetting steps by over 90% compared to single-channel pipettes.

Every TopPette 12-channel pipette is calibrated according to ISO 8655 and supplied with an individual calibration certificate, delivering exceptional accuracy (e.g., systematic error as low as ±2.4% at 10 µL) and precision (CV as low as ±1.6% at the same volume). The 9 mm channel spacing is perfectly compatible with standard 96-well plates, 384-well plates, deep-well blocks, and tube strips. The lower housing on select models is autoclavable at 121°C for 20 minutes, allowing routine decontamination for aseptic applications in cell culture and microbiology.

Key ergonomic features include a lightweight body optimized for 12-channel balance, a low-force plunger, a relaxed finger hook, and a staggered tip ejector that reduces ejection force by up to 50% compared to traditional designs — especially critical for ejecting 12 tips simultaneously. A large digital display provides unambiguous volume confirmation, and the volume locking mechanism prevents accidental setting changes during operation.

For the clinical laboratory scientist and molecular biologist working with high-density plates, the TopPette 12-channel pipette delivers the throughput, accuracy, and ergonomic comfort required for ultra-high-volume ELISA, qPCR master mix distribution for 384-well plates, clinical chemistry sample transfer, and drug discovery high-throughput screening. For the patient, consistent, error-free 12-channel processing ensures that diagnostic results are reproducible and reliable, with dramatically faster turnaround times that directly support timely clinical decision making in high-volume testing environments.
