Say Bolt Viscometer Apparatus
Product Code : EL-FTLE-10887
Say Bolt Viscometer Apparatus (code EL-FTLE-10887) is a two-tube digital viscometer used to measure the Saybolt viscosity of petroleum products, as the time in seconds a 60 mL sample takes to flow through a universal or furol orifice. It works between 21 and 99 °C (70 to 210 °F) in a water-oil bath with stirrer, cooling coil and digitally regulated electric heater, is rated at 750 W and comes with two of each orifice, 5 lt of heat transfer oil and two 60 ml glass flasks.

What Is the Say Bolt Viscometer Apparatus Used For?
Saybolt viscosity is an empirical measure of how thick an oil is at a given temperature: the result is simply the time, in seconds, that a 60 mL sample takes to flow through a standard orifice into a receiving flask. The operator brings the water-oil bath to the test temperature with the digitally regulated heater, stirrer and cooling coil, fills a tube, then pulls the stopper and times the flow into the 60 ml glass flask. The universal orifice is used for lighter oils and the furol orifice for heavier, more viscous products such as fuel oils. The standards listed are ASTM D88 and AASHTO T72.
What to Specify When Ordering
- Quantity — the number of viscometers required.
- Thermometers — whether the 6 thermometer viscosity set with 0.1 °C subdivisions is needed, since it is ordered separately.
- Filter funnel and withdrawal tube — whether these separately ordered items are wanted.
Frequently Asked Questions
How is Saybolt viscosity reported?
It is reported in seconds: the time a 60 mL sample takes to flow through the universal or furol orifice at the chosen temperature, anywhere between 21 and 99 °C (70 to 210 °F).
What comes with the two-tube unit?
It is supplied with 2 universal and 2 furol orifices, 5 lt of heat transfer oil, a key, two 60 ml glass Saybolt viscosity flasks, two thermometer supports and two stoppers.
Are thermometers included?
The viscosity thermometer set is ordered separately. It has 6 thermometers covering 19 to 27, 34 to 42, 49 to 57, 57 to 65, 79 to 87 and 95 to 103 °C, each with 0.1 °C subdivisions.
When is the furol orifice used instead of the universal orifice?
The furol orifice has the larger opening and is used for heavy, more viscous products such as fuel oils, while the universal orifice suits lighter petroleum oils.
What are the size, weight and power rating?
The apparatus measures 450 × 300 × 550 mm, weighs approx. 10 kg and has a power rating of 750 W.
Which standards are listed for it?
The standards listed are ASTM D88 and AASHTO T72, and the viscometer is used on petroleum products at specified temperatures.
