same, though badged differently, edulab?We have this one
An efficient design for all the usual electrostatic experiments and for where a continuous source of high voltage is required. It has a strong metal base with profiled hand grips, housing a quiet running a.c. motor. The discharge sphere may be plugged into the base or supported separately...www.philipharris.co.uk
I replaced the old Combs on one of ours they were " very flimsy aluminium foil like combs" with two little bits of stamped aluminium mesh made lovely points when cut works greatOurs is quite old but I just changed the belt, now it's almost too good! Even works on very damp days
The only thing that will age is the belt, should be able to source a replacement. Make sure there is a small gap between the belt and the brushes. Make sure the dome is really clean.Has anyone purchased a new Van de Graaff recently? Ours does not work so well as it used to (I estimate it's over 30 years old). I have been asked to cost up a new one, but they do seem to vary in cost.
