Safety Notes and Warnings Thermo Fisher Scientific does not assume respon- sibility for independent repairs and consequences of improper use. Do not clean the unit with solvents (fire risk!) - - a wet cloth soaked in household detergent is nor- mally sufficient.
Unpacking / Setting Up Unpacking 5.1 Transportation damage? Notify carrier (forwarding merchant, railroad, post office etc.), Compile a damage report. 5.2 Before return delivery: Inform dealer or manufacturer (Small problems can often be dealt with on the spot). 5.3 Contents of Delivery The following standard accessory is delivered together with the falling ball viscometer:...
Unpacking / Setting Up 5.4 Material for use No other material except for cleaning material (800-0125 cleaning piston, 800-0131 cleaning brush) is necessary at normal use. 5.5 Spare parts See chapter 13. 5.6 Waste disposal The transportation packing is made out of paper and can be recycled.
Unit Description Unit Description 7.1 Principle of the measurement The HAAKE Falling Ball Viscometer measures the viscosity of transparent newtonian liquids. This viscosity is correlated to the time a ball requires to fall a defined distance. The rol- ling and sliding movement of the ball through the sample filled into a slightly inclined cylindrical measuring tube is de- scribed by means of the fall time.
Measuring 9.1 Preparation for a test 9.1.1 Temperature control The HAAKE Falling Ball Viscometer may be temperature controlled in a temperature range from --20 C up to +150C using liquid circulators. Ensure that the sample to be measured is homogeneously tempered.
Measuring 9.1.3 Selection of the balls The standard ball set contains 6 balls, which pass through the measuring tube of an inner diameter of approximately 15.94 0.01 mm. Order- Ball Made of Density Diameter Constant K Recomm. (standard of the ball (approx.) measuring values)
Measuring 9.2 Measurement of the falling times The jacket tube snaps into a defined 10-position at the bot- tom of the instrument. By turning over the jacket tube, the ball is set to the measu- ring position. The falling time of the ball moving from the ring mark A to ring mark B is determined by using a stop watch.
Measuring 9.3 Evaluation of the test results The dynamic viscosity (in mPas) is calculated using the following equation: = K ( -- ) ¡ t where: K = ball constant in mPascm /gs (see chapter 11) = density of the ball in g/cm (see chapter 11) ...
Measuring To evaluate the reliability of the results the following criteria may be used: 9.3.1 Reproducibility (one person, one instrument) If one person determines two test results under identical test conditions, these results are supposed to be acceptable if they do not vary more than the figures stated in the table below from the average value.
Measuring 9.4 Viscosity determination of gases The viscosity determination of gases has to be done with ball G which is made out of glass. The measuring tube must be closed with rubber stop- pers fitted with glass stopcocks. Measuring tube, glass ball and gas must be clean and dry.
Cleaning the Measuring Tube 10. Cleaning the Measuring Tube Usually the tube is cleaned by rinsing it with a suitable solvent. High viscous liquids (glue and heavy oils, etc.) have to be removed with the cleaning piston which is supplied with the instrument.
Calibration 11. Calibration of the Falling Ball Viscometer The falling ball viscometer is checked according to the HAAKE regulations before delivery. The geometry relates strictly on the DIN 53015/ISO 12058 and therefore the listed ball constants can be used. The calibration of the instrument can be done using nation- ally recyclable calibration fluids.
Page 21
Calibration The calibration fluids should be stored in dark rooms and be used within 3 months after their date of expiry. The disposal depends of the composition of the substance which is listed in the “EC - - SAFETY DATA SHEET”. It is absolutely essential that for calibration the instructions for filling the tube and cleaning are closely adhered to.
Maintenance by the User 12. Maintenance by the User 12.1 Exchange of the measuring tube and the jacket tube Unscrew the screws 4 and remove brace 11. Loosen threaded bush 18 with socket spanner no. 003-2110. Unscrew connecting rods 20. Now remove both cover lids 7 and 9.
