#CMT# #/CMT# A receiver (180) with a light source (110) at its side, a detector (120) and electronics (130) form the monitoring unit (010). The receiver repeatedly defines positioning of a vessel unit (150). The source produces a plane of illumination parallel to the rows of containers, near their upper edges, over the entire length of the vessel unit. The detector is on the side of the receiver opposite the source. It has individual light intensity detector elements (121) connected to the electronics. The latter produce a signal profile (131) of light intensity. Free access to each container is permitted, for a channel (162) of the transfer unit. #CMT# : #/CMT# An independent claim IS INCLUDED FOR the corresponding method of monitoring. #CMT#USE : #/CMT# Monitoring equipment for manual pipetting operations. #CMT#ADVANTAGE : #/CMT# Normally a standing position is adopted when pipetting, and there are stringent requirements concerning the accuracy of location. This demands high concentration. Over time, these conditions considerably stress the operator, both mentally and physically. The new equipment helps maximize accuracy whilst minimizing operator stress. Accuracy is improved, especially where smaller sample matrices, e.g. smaller micro-titration plates, are used. High costs associated with robotic pipetting can be saved. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a plan view of the pipetting arrangement. 010 : monitoring unit 110 : light source 120 : detector 121 : detector elements 130 : electronics 131 : signal profile 150 : vessel unit 162 : channel 180 : receiver. |
