Hi, Anupama,

Please have a look at: www.aurorascientific.com Aurora Scientific Inc. has
different setups for force measurements in the micro N.  Further on  Aurora has
special setups for studies on muscle physiology.   We are currently using two
force transducers from the "Series 400A Force Transducer Systems".  I have no
problems with measuring forces in the low micro N range.  By the way, this
company has a great customer service and they are extremely helpful, I would
definitively give them a call.
I hope this will help.

With best regards,
   Marc


PS If you need any further information just send me an email.
