Kinematic Viscometer Bath A C C U R A C Y — M e a s u r e m e n t s are made with an error not greater than ί 0 . 2 % from true kinematic viscosity when the viscometer constant is calculated as a simple integer in order to simplify calculation. Even greater accuracy can be secured if required by using the actual constant. S P E E D — A t a conservative estimate this method takes one-fifth the time required by other methods. The speed with which samples can be run, with up to nine samples being run at a time for continuous operation, makes it practical to run checks of all items of importance. E A S E O F O P E R A T I O N — Both the test procedure and the operation of the apparatus are simplicity itself. Cleaning requires only about thirty seconds without removing the viscometer tubes. Tubes need be re moved only for changing sizes and types.
The Klett Huorimeter
No. 2070
Designed, for the rapid and accurate d e t e r m i n a t i o n of t h i a m i n , riboflavin, and other substances which fluoresce in solution. The sensitivity and sta bility are such t h a t it has been found particu larly useful in determining very small a m o u n t s of these substances.
E C O N O M Y — Continuous operation permits full use of the operator's time. Highly skilled operators are un necessary. Cost per test is appreciably lower than by other methods. THE RANKIN VISCOMETER TUBE is now obtainable for use on black oils. The extreme accuracy and speed possible with this new tube will make the Braun ShellDesign Kinematic Viscometer Bath more essential in your laboratory than ever before. WRITE FOR BULLETIN C-144.
