    Abstract: A small volume laboratory filter having a thin rectangular body and coaxial inlet and outlet sleeves connected to opposite ends thereof. A very thin filter cavity is formed in the body and lies in a plane inclined slightly to the common axis of the inlet and outlet sleeves. The cavity is divided by a filter membrane into extremely thin chambers, one communicating with the inlet sleeve and the other with the outlet sleeve. A rigid package for the filter is sealed across one end by a flexible cover which when stripped from the package exposes the inlet sleeve so that it may be readily engaged by a syringe nipple or other fluid source without the user having to touch the filter. When the inlet sleeve is engaged, the filter may be withdrawn from the package.

    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: A pipette tip mounting shaft includes outwardly circumferentially extending locking lobes over which the pipette tip collar is mounted. The locking lobes preferably include an inclining ramp portion that gently flexes and distorts the pipette tip collar out-of-round as the mounting shaft is inserted into the pipette tip, rather than the stretching tip collar. Each locking lobe also includes a declining ramp portion which extends upward along the mounting shaft. The peak of the lobes is preferably curved. When the pipette tip is fully mounted on the mounting shaft, a locking ring on the inside surface of the tip collar engages the declining ramp of the lobes to provide an over-center engagement, however, the required ejection force is small.

    Abstract: In one aspect, 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 located above a stop member and a lower sealing section located below the stop member. 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 or shoulder separating its upper collar from the tip sealing area which is located below the circumferential shelf. The tip collar preferably includes a locking ring located at or near the upper opening for the mounting shaft. The dimensions of the collar, and in particular the distance between its circumferential shelf and the locking ring, are selected to match the dimensions of the mounting shaft between the stop member and the upper end of the locking lobes, thus locking the pipette tip in a secure, reliable position and orientation while using ergonomic insertion and ejection forces. The locking lobes preferably include a ramp portion that 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 between the lower sealing section of the mounting shaft and the sealing ring in the upper end of the barrel of the pipette tip.

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.
