<p>#CMT# #/CMT# The pipetting device has valve arrangement (200) with valve device (101") for adjusting a pipetting pressure. The valve device has valve chamber with pump unit which is connected with the valve chamber for producing a chamber pressure in the valve chamber. A pipette and bypass channel (104") which is opened to environment are respectively connected to the valve chamber. The valve device is formed such that it is distributed to produce the desired pipetting pressure in the pipette and the chamber pressure on the pipette and the bypass channel. #CMT# : #/CMT# An independent claim is included for method for manufacturing pipetting device. #CMT#USE : #/CMT# Pipetting device for fluid sample pipetting process in medical, biological, biochemical, chemical and other laboratories. #CMT#ADVANTAGE : #/CMT# The accurate pipetting and dispensing processes in pipetting device are performed efficiently regardless of pipette container size, as the valve device is formed such that it is distributed to produce the desired pipetting pressure in the pipette and the chamber pressure on the pipette and the bypass channel. By rotationally symmetrical design of the valve piston and the interior area of the piston support element, the high manufacturing precision of the pipette device is achieved. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-sectional view of valve assembly of pipette device. 101" : Valve device 103" : Pipette 104" : Bypass channel 110" : Valve piston 200 : Valve arrangement.</p> |
