SAMPLE CELL FILLING DEVICE FOR USE REMOTELY FROM A POLARIMETER AND METHOD OF USING THE SAME
First Claim
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, the sample cell having;
a first optical window at a first end and a second optical window at a second end; 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 with a sample injecting device;
a light source that transmits light from the first optical window to the second optical window; and
a diffuser viewing screen that receives light exiting from the second optical window such that light from the viewing screen can be observed by a user to determine the quality of the sample fill.

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 inclined angle, the sample cell having a first optical window at a first end and a second optical window at a second end; 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 diffuser viewing screen that diffuses light from the focusing lens such that light from the viewing screen can be observed by a user to determine the quality of the sample fill. - View Dependent Claims (12, 13, 14, 15)

16. A method of checking the quality of a fill in a sample cell using a sample cell filling device away from a polarimeter, the method comprising:
-
placing an empty sample cell in a recess of a sample cell filling device, the sample cell having a first optical window at a first end and a second optical window at a second end, the recess being inclined to receive the sample cell at an inclined angle such that one of the first and second windows is lower than the other window, the filling device having a light source that transmits light from the first optical window to the second optical window, and a viewing screen that receives light exiting from the second optical window such that light from the viewing screen can be observed; filling the sample cell with a sample through the filling port adjacent to the lower window; observing the quality of the sample fill through the viewing screen; determining that the sample cell has been filled when a uniform illumination through the viewing screen is observed; removing the filled sample cell from the filling device and placing the filled sample cell in the polarimeter. - View Dependent Claims (17, 18, 19, 20)
