Long series in colonies, rows, and microplates-that is the area of research in which the multichannel pipette is becoming an ever-increasing force. Ergonomics (reduced weight and ease of use) was the main reason that the Multichannel Research model was developed. This high-performance 8- or 12-channel pipette provides effective, precise, and rapid processing of long series for a wide spectrum of applications. Multichannel Research Pipettors offer a specially designed nose cone o-ring seal to reduce force required for attaching and ejecting pipette tips. 8-channel and 12-channel manifolds (lower sections) can be easily interchanged. Ideal for serial dispensing in molecular biology applications and for all types of immunological assays (i.e. applying antibodies, washing, or stopping).
