1. A sample cell filling device for filling a sample cell to be used remotely from a polarimeter comprising:
- a liquid-sealed housing having a recess for receiving and supporting the sample cell at an inclined angle, the sample cell having;
a first optical window at a first end and a second optical window at a second end along a longitudinal axis of the sample cell; and
a first filling port located near the first end and a second filling port located near the second end, at least one of the first and second filling ports adapted to form a temporary liquid tight seal when a sample injecting device is received therein;
a light source that transmits light from the first optical window to the second optical window; and
a viewing screen, wherein light exiting the second optical window is directed to the viewing screen.

Abstract
A sample cell filling device for filling a sample cell to be used remotely from a polarimeter is provided. The filling device includes a liquid-sealed housing, light source and a diffuser viewing screen. The housing has a recess for receiving the sample cell, the sample cell having first and second optical windows at the respective ends. A light source transmits light from one optical window to the other optical window. A diffuser viewing screen receives light exiting from the sample cell such that light from the viewing screen can be observed by a user to determine the quality of the sample fill.

11. A sample cell filling device for filling a sample cell externally of and to be used remotely in a polarimeter comprising:
-
a liquid-sealed housing having a recess for receiving the sample cell at an angle between about 10 to about 50 degrees relative to a horizontal plane, the sample cell having a first optical window at a first end and a second optical window at a second end along a longitudinal axis thereof; a light source positioned within the liquid-sealed housing and operable to transmit light from the first optical window to the second optical window; a focusing lens positioned within the sealed housing and to receive light from the second optical window; a viewing screen, wherein the viewing screen receives light from the focusing lens, and further wherein the viewing screen is physically adapted to diffuse the light it receives. - View Dependent Claims (12, 13, 14, 15)
