Abstract: An experimental instrument for examining permeability of a flowing cornea is used for imitating a lacrimal layer in the front part of a cornea or the back part of the cornea (an aqueous humor) by means of storing a various kinds of solutions comprises a cell body including a stirring part of a cylindrical wall and a bottom surface at a bottom part thereof, a constant temperature tank which surrounds the cell body all around a sample membrane setting part which is protrusively arranged at an outer surface of the call body and can set a sample membrane such as a contact lens used as a cornea or a corneal model, an outflow tube which is protrusively arranged at an outer surface of the stirring part and makes a solution in the cell body discharge, an inflow tube which is protrusively arranged at an upper part of the cell body and makes the solution flow inside of the cell body, a magnet rotator which is arranged inside the stirring part of the cell body, and a magnet stirrer which makes the magnet rotator inside

Abstract: A micro-flow controlling pump according to the present invention is used for controlling a micro-flow of a liquid in an experiment using a chemical agent for examining permeability of a membrane, reaction of a flow system, reflux of vital tissues, or the like. The micro-flow controlling pump includes: a pump body formed to have a cylindrical wall and a bottom surface, and be provided with an outflow tube formed at an outer surface of the cylindrical wall; a cover body formed to be detachably attached to the pump body and be provided with an inflow tube; a magnet rotator arranged inside the pulp body having criss-crossing blade parts; and a magnet stirrer arranged outside the pump body, having magnetic force by which the magnet rotator in the pump body can be rotated.

Abstract: This is a device for supporting an animal clamp (100) fixing a small laboratory animal in a specified position with respect to a testing apparatus (300). A base board (2) is fixed to the testing apparatus (300). An elevating board (4) is raised or lowered by jacks (31, 32) installed between it and base board (2), and a clamp mounting board (8) is tilted by jack (61) and sliding member (62) installed between it and elevating board (4).As a result, the height position and inclination angle of the animal clamp (100) mounted on the clamp mounting board (8) are determined, and they may be finely adjusted by properly manipulating the jacks (31, 32, 61). The animal clamp (100) does not slip off the clamp mounting board (8) because of the clamp slip preventive flange piece (7).

Abstract: Here is described a portable chiller with which an ophthalmic solution, cosmetic preparation, beverage or the like in a small container can be conveniently chilled. This portable chiller consists generally of a cylinder filled with a liquefied refrigerant gas and a chiller case. This chiller case includes a cylinderloading compartment, a cooling compartment in which the article is chilled, and a refrigerant ejection device for ejecting the refrigerant from the cylinder accommodated in the cylinder compartment into the cooling compartment.
