    Abstract: A hand-held, multi-channel pipettor has an electronically controlled motor to reposition pipette tips for different center to center spacing. Each repositionable tip fitting assembly has a cam following pin that is driven by cam tracks in a motor driven roller drum. Stationary ports for the multiple aspiration cylinders are strategically placed to simplify management of flexible tubes leading to the repositionable pipette tip fitting assemblies. The pipettor has a user interface that can be operated conveniently by one hand to reposition pipette tips. It has a pipette tip ejection mechanism with a sinusoidal stripper bar.

    Abstract: The invention relates to a pipette tip mounting shaft configuration and a disposable pipette tip having a matching configuration. The mounting shaft includes a locking section located above a lower sealing section. The locking section has outwardly extending locking lobes circumferentially spaced around the mounting shaft and located above a stop member that separates the lower sealing section from the upper locking section. When the mounting shaft is fully inserted into the collar of the mating disposable pipette tip, the tip locks onto the mounting shaft. The bore of the pipette tip includes a circumferential shelf separating its upper collar from the tip sealing area which is located below the circumferential shelf. The locking lobes gently flexes and distorts the pipette tip collar out of round as the mounting shaft is inserted in the pipette tip, rather than stretching the tip collar. The circumferential shelf on the pipette tip between the tip collar and the barrel isolates the sealing area at the upper end of the barrel from distortion, thus facilitating reliable sealing engagement.

    Abstract: Microplates and methods for manufacturing microplates. The microplate is designed to allow UV radiation to pass through the bottom wells of the microplate so that the microplate can be used for assaying samples by use of UV absorbance. In one embodiment, the microplate comprises at least first and second wells, each well having a UV permeable bottom. In another embodiment, the microplate comprises a frame having an upper portion and a lower portion contiguous with the upper portion and a sheet disposed between the upper portion and the lower portion and defining the bottom of at least one well of the microplate. One embodiment of the method includes steps of inserting a sheet of UV permeable material into a mold cavity that includes sections shaped to form the sidewalls of the plurality of wells, injecting molten plastic material into the mold cavity, and cooling the plastic material to form the microplate with the plastic material forming the sidewalls of each of the first and second wells and the sheet of UV permeable material forming the bottom of each of the first and second wells. Another embodiment of the method includes providing an upper plate defining sidewalls of at least one well, adhering an intermediate layer to the upper plate and adhering a sheet of UV permeable material to the intermediate layer. A further embodiment of the method includes inserting a sheet of material having at least one hole into a mold cavity, injecting a molten plastic material into the mold cavity and cooling the plastic material to form a microplate.

    Abstract: A device and method for growing tissue or cells on both sides of a membrane includes a cylindrical body which may be stood on either end in a culture well. A frame is slidably mounted in the body and carries a membrane, on both sides of which tissue or cells are to be grown. A tissue or cell sample is placed on the upper surface of the membrane and media is supplied to the well on the outside of the body. Passages at the bottom of the body allow the media to flow to the membrane and nurture the sample to cause its growth. When the first monolayer is grown, the body is inverted and the frame is pushed to the other end of the body, preferably by a jig supplied for that purpose. A second cell sample is deposited on the other side of the membrane, again on top of the membrane and it is nurtured by media supplied primarily from the reservoir on top and secondarily through the membrane.

    Abstract: A laboratory article, and in particular a cluster plate is provided including a plurality of wells supported by a structural framework including a peripheral wall. At locations in the structural framework a plurality of protrusions are provided so as to support the cluster plate on a support surface, such as a benchtop, in a point-to-point manner. Such point-to-point support allows the article to be moved across the support surface without the generation of unpleasant audible vibrations. According to a preferred embodiment, a cluster plate having protrusions extending from the lower edge of a peripheral wall is provided.

    Abstract: A filter for a centrifuge tube including a pressure filter for separating a mixture under centrifugal force. The filter tube is adapted to fit within the upper portion of a standard plastic centrifuge tube. The filter tube has a pressure filter at its lower end and an opening at its upper end adapted to be sealed by a cap extending from the centrifuge tube to hold the filter tube securely in position within the centrifuge tube. The filter tube is filled with a mixture of permeable and non-permeable materials and when the composite centrifuge tube and filter tube is spun in the centrifuge, the centrifugal force causes the permeable materials to flow through the filter and collect in the bottom of the centrifuge tube while the non-permeable materials are retained in the filter tube.
