APPENDIX 6
Sample and Cuvette Adapters
Test tube and cuvette size, apertures, and the sample cell path length all affect
the sensitivity of the instrument. In general, the greater the diameter of the test
tube or cuvette (the greater the path length), the more sensitive the readings and
the lower the linear range.
The smaller the window and path length, the less sensitive the readings.
You must recalibrate the instrument if you change cuvette adapters, or if you
change path lengths or attenuators.
A. Installing and Removing Sample Adapters
Available for the TD-700 are a variety of sample adapter to cater to the
sample size needs of researchers. These are :
-25 mm test tube adapter
(P/N 7000-982, standard with TD-700 model 7000-000)
-13 mm test tube adapter
(P/N 7000-981, standard with TD-700 model 7000-000)
-10x10 mm square cuvette adapter
(PN 7000-988, standard with TD-700 model 7000-009)
-Minicell adapter
(P/N 7000-951, fits inside 10x10 cuvettes adapter
P/N 7000-009)
To install/use adapters
1. Open the lid to the sample chamber.
2. Align pin or point arrow on the adapter to the silver dot on the TD-700.
3. Slide the sample adaptor inside the sample chamber and push down
until it is fully seated in the chamber.
To remove sample adapter:
1. Open the lid to the sample chamber.
2. Remove the test tube.
3. Grasp the sample adaptor by the rim and pull straight up.
