Cotton string

Vertical surface collectors can readily provide information on relative drift (e.g., the amount of drift from one field trial compared to another). However, it is difficult to obtain absolute data unless the precise collection characteristics are known for the droplet size spectrum at the point of spray collection, wind speed and air turbulence intensity. " The SDTF conducted studies in wind tunnels to compare the collection efficiency of different types of drift collector used in its field studies. These studies showed that collection efficiency on strings was several orders of magnitude higher for 0.8-mm diameter cotton string than for 2-mm diameter polyethylene line and vertical o -cellulose strips or squares. The higher collection efficiency for the cotton...

It is not difficult to insulate. Cut a strip of insulation making it 1 metre long and a bit wider than the vessel. (Roll out a length and cut off). Place it round the vessel and tie in place with cotton string. Cut off surplus insulation round the top and bottom of the vessel and cut out the holes. The insulation is very easy to cut so this is simple. Put on more layers and bind fast until you finally have a thickness of 10 mm or more. It s finished ...

Alternatively, iron electrode clamps, sealed to the P3rrex caps with asbestos-waterglass mixture, are used with no cooling. In that case, the Pyrex caps may have to be woimd with cotton string, wetted with water to remove the heat.
