Instrument Repair & Service Centre

Instrument Repair & Service Centre delivers the following services:

  1. Develop instruments/experimental set up for science colleges and other institutions.
  2. Repair and redesign instruments/experimental set ups for science laboratories of colleges and other educational institutions.
  3. Impart training to laboratory technicians of educational institutions in repair and maintenance of laboratory instruments.
  4. Organize workshop, seminar and demonstration programmes on instruments.

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.
