Abstract
A freely traversable metering head with numerous metering devices, wherein the metering devices are each provided individually or block-by-block with an activating device, and wherein a controller traversable with the metering head is designed for the independent operation of one or more activating devices. Metering devices for such a metering head and procedures for their use are also disclosed.
Claims19
A metering head that can be freely traversed by an actuating device and having a plurality of metering devices, which, as individual metering devices or as metering device blocks, are provided with respective activating devices individually or in blocks, wherein the metering devices comprise:
- picking needles or micropipettes arranged in accordance with orientation of sample volumes in a microtiter plate, the activating devices each being formed by a pneumatic cylinder having an actuating needle for activating the metering devices or metering device blocks, and
- a controller traversable with the metering head provided with control outputs whose number at least equals the number of pneumatic cylinders and which are connected with an accompanying control output by a pressure line, such that the metering devices or metering device blocks can be independently activated during metering head operation.
