Pretreatment of the glass capillary

Absolutely, pretreatment of the glass capillary with a gaseous phase
high contact angle contact modifier.  I would suggest either a
Perfluourosilane or a FDTS, treatment will render the glass highly
hydrophobic and resistant to anything sticking to it.  Contact me for
further details. [email protected]  Bill Moffat

Subject: [mems-talk] Pretreatment of the glass capillary

Hi all,

I need some information on this.

I am using Fluorescent Carboxyl Magnetic particles (SPHEROTEC Inc) which
will be passed through a Borosilicate glass capillary. Now what I have
observed during the flow of the above magnetic particles (dispersed in
H20), some of the particles are sticking to the glass surface. So can
anyone suggest that any pretreatment of the glass capillary will solve
the problem?

Regards
Asfer
