Instrument
Development Service Centre(IDSC)
This is an
ongoing project of the division
at the department of Physics,
Cotton College Guwahati. Under
the scheme new instrument /experimental
set up are developed as well
as instrument/experimental set
up of the colleges which become
defective are repaired. Repairing
of instruments of college laboratories
are carried out on 'first come
first service' basis. Development
of instrument/experimental set
up are also taken up on a central
need of the colleges.
Some
of the institutions which have
received services from the centre
are Cotton College, Guwahati;
North Guwahati College, North
Guwahati; M. C. College, Barpeta;
B. Barooah College, Guwahati;
Handique Girls' College, Guwahati;
Jorhat Science College, Jorhat;
Birjhora Science College, Bongaigoan;
Darrang College, Tezpur; Pandu
College, Guwahati; Pub-Kamrup
College, Baihata Chariali; B.H.
College, Srimanta Sankar Academy,
Guwahati; Solid State Laboratory,
Gauhati University; IIT, Guwahati
and College of Veterinary Science,
Khanapara, Guwahati.
