8170-Ostwald Viscometers
Read more- Ostwald Viscometer or U-tube viscometer is a chemical instrument that is used to measure the viscosity of a liquid with a known density.
- This viscometer is named after the German chemist, Wilhelm Oswald.
- This viscometer is a U-tube with two bulbs separated by a capillary tube.
- The two bulbs act as reservoirs for the liquid.
- The small reservoir is located at a higher level than the larger reservoir.
- There are two marks at the top and the bottom of the small bulb.

8190-Stalagmometer
Read more- A stalagmometer a simple and normally manual instrument for measuring the surface tension(SFT) of liquids and, more rarely, the interfacial tension (IFT) between two liquids.
- The measurement involves determining the mass or volume of drops of liquid falling from the tip of a vertical capillary after flowing through it.
- The stalagmometer is an earlier form of the drop volume tensiometer, which measures the dynamic IFT or SFTwith the help of an electronically controlled liquid feed and optical drop detection.

8230-Thistle Funnels
Read moreUsage Guide:
- Thistle Funnels are used to add liquids to a narrow necked flask or other container.
- They are usually passed through a bung or clamped in place.
- They are particularly useful if the liquid addition must be low down in the flask where a funnel or dropping funnel would have too short a stem.
