Abstract: The present invention provides an animal restraining device to securely accommodate the animal and further prevent it from escaping the device. The device includes a substantially cylindrical shaped body having a front end, a rear end and a cavity. The front end includes an opening to the cavity for passage of the animal during loading and unloading of the animal. The device also includes a slot formed in the body configured to receive a tab following the loading of the animal in the cavity in order to block the animal from escaping the device. The device further includes an access opening formed on the top portion to permit access to body of the animal.

Abstract: An enclosed magnetic stirring bar arrangement includes a housing formed by front and rear walls interconnected by a peripheral wall, so as to define a substantially hollow interior chamber within said housing. An operational opening is formed within the front wall and at least one discharging aperture is provided in the peripheral wall. A magnetic stirring member is movably positioned within the substantially hollow interior chamber, whereby rotational motion of the magnetic stirring member facilitates entering a liquid into the substantially hollow interior chamber and discharging the liquid from the interior chamber through the at least one discharging aperture.

An operational opening is formed within the front wall and at least one discharging aperture is provided in the peripheral wall. A magnetic stirring member is movably positioned within the substantially hollow interior chamber, whereby rotational motion of the magnetic stirring member facilitates entering a liquid into the substantially hollow interior chamber and discharging the liquid from the interior chamber through the at least one discharging aperture.

Abstract: A laboratory implement consisting of a body formed with at least a blade at one end thereof is used for handling biological samples. The blade is provided with photoluminescent qualities, so as to emit visible light when subjected to ultraviolet light. In the method, the implement is positioned in a hand of the user with the blade facing the biological samples. The samples are cut by the blade in darkness under ultraviolet light, in such a manner that the blade is visible to an operator.

Abstract: A micro volume, filtered pipette tip device useful with either of two respective pipettors comprising (i) a manual or electronic, air displacement pipettor operable within the approximate range of 0 to 20 microliters and having a relatively long insert tip, and (ii) a manual or electronic, air displacement pipettor operable within the approximate range of 20 to 200 microliters and having a relatively short insert tip. The filtered pipette tip device includes a pipette tip body having insert and fill chambers extending in continuous tapering configuration from the mounting end to the fluid contacting end. A filter is positioned within the axial bore in the intermediate section, providing a dividing barrier between the insert and fill chambers of the pipette tip device. The insert chamber includes a tapering internal wall structure configured to receive a continuously tapering terminal insert portion of each of the two respective pipettors in a snug, sealed fit within the insert chamber.
