Abstract
A press for compressing a liquid-bearing absorbent article to transfer a portion of the liquid materials to a contiguous article has two concentric pressure feet. One is an outer foot member that bears against the liquid-bearing article along the periphery of the pressure area, and the other is an inner, deformable and contoured foot member that applies pressure to the liquid-bearing article progressively along the pressure area. A photometer can be combined with the press to measure constituents or other properties of the liquid materials being transferred.
Claims3
An instrument for analyzing liquid material carried in an absorbent article by monitoring a reactant formed from the liquid material in a reaction pad, said instrument comprising:
- A. a platen member of material transparent to selected radiation and having a first surface for supporting the pad during pressing,
- B. pressure means having a pressing surface disposed on a first side of said platen member for compressing the absorbent article between said pressing surface and said first surface of said platen member thereby to press the liquid material from the absorbent article to the reaction pad, and
- c. a fluorometer;
- 1. disposed on the opposite, second side of said platen member,
- 2.
