A pipette comprising a cylinder with a piston movable inside the cylinder for aspiring and dispensing liquid, and a handle portion for gripping the pipette, wherein the pipette further comprises an imaging device element for obtaining images that assist the use of the pipette.

Pipette comprising imaging device element

A pipette is described which includes a piston for aspirating liquid into and dispensing out of a container in the pipette. The pipette is provided with at least one tracking element which is able to count the magnitude of some variable or variables relating to the amount of use of the pipette, at least one operating device for creating a limit magnitude for each variable, and for giving information when the limit value is exceeded. Thus, the user may, for instance, be warned when he may be exposed to high workload stress possibly causing injuries.

Pipette with a tracking system

The invention relates to liquid dispensing and concerns a pipette comprising at least one aspiration channel with a piston. At the lower end of the aspiration channel there is an extension channel () and at its end a pipette tip mounting piece () onto which a pipette tip () is attached. On the pipette tip mounting piece there is a surrounding groove () and in the groove a sealing ring (). The width of the groove in the axial direction is at least 1.1 times the thickness of the sealing ring in the axial direction. When the mounting piece is pushed into the pipette tip, the inner wall of the tip can move the sealing ring upwards in the groove. The construction can provide a reliable sealing despite of inherent dimension differences between different tips and mounting pieces.

Sealed pipette

The invention relates to a pipette having a piston and a barrel with variable diameter at least in the portion passing by the sealing point.

Calibratable pipette

A handle pipette including at least one cylinder with an upper end and a lower end, said cylinder having a movable piston, an elongate handle (), by which the pipette can be manually gripped, said handle having an upper part, and in the upper part of the handle, a sideways extending finger support (), which finger support () is at least partly flexible and/or it can be shaped by the user.

Handle pipette

A support pipette including at least one cylinder with an upper end and a lower end, each cylinder having a movable piston, and an elongate handle () with an upper part and a lower part, at which handle the pipette can be manually gripped, wherein the lower part () of the handle () includes a sideways protruding lower support ().

Support pipette

The invention relates to a pipette, comprising a tip remover element which, upon moving it against a tip, disengages the tip. The remover element is operated with a mechanism, comprising a rotatable ramp member which is provided with a circle-forming ramp surface, including one or more segments within which the ramp surface has a high point and a low point, whereby the ramp surface, upon rotating through a single segment, forces the remover element first to move against the tip and then allows it to return.

Pipette with a tip removing mechanism

The invention relates to an electric pipette () comprising a body (), a tip part (), a hook part (), a push-button part () and a display part (), said body () having a vertical axis () and at least one of the parts selected from the group consisting of the hook part (), the push-button part () and the display part () is rotatable about the vertical axis () of the electric pipette () correspondingly by an angle &#x3c6;, &#x3c6;or &#x3c6;.

Electric pipette

The invention relates to a controllable pipette comprising a piston actuated by a motor, a control system allowing actuation of the piston according to a given pipetting function consisting of several steps, setting keys () for selecting the desired pipetting function, a switch (), which activates the function steps when depressed, and a display (). The control system comprises a change function, whose activation enables a change of the selected function in the process of its operation. When the change function can be activated, this is indicated on the display and it can be activated by depressing a given setting key.

Controllable pipette

A pipette includes a housing defining a suction chamber. A piston is configured to move in the suction chamber. A first retainer mechanism includes a first threading configured to limit a motion of the piston in the suction chamber. A second retainer mechanism includes a second threading configured to limit the motion of the piston in the suction chamber, the second threading having a pitch less than a pitch of the first threading.

Adjustable pipette

Pipette stand

The patent application discloses a multi-cylinder pipette (1). The pipette specifically comprises 16 4.5 mm spaced channels (5), being thus suitable for use with a plate comprising equally spaced 16.times.24 wells. The set of cylinders of the pipette has been assembled from separate elements. A set of cylinders composed of elements provides ease of manufacture. Moreover, the same element and other components can be assembled to provide various pipettes.

Multi-cylinder pipette

A pipette provided with a tip remover, which pipette has a lever mechanism, in which the tip is pressed off the pipette. In this way, it has been possible to decrease the force needed for the loosening.
