Re: [ccp4bb] DLS

[Andreas Förster]

The Malvern is indeed very nice.  The only issue I have with ours is 
that it doesn't do plates.  This makes buffer screening a very laborious 
busy that is best left to graduate students.

Hiya.

My two penneth on the Malvern Zetasizer.

Simple, idiot-proof operation. Software is easy and intuative. Reports
are customisable to give you what information you want.
Problems easy to trouble shoot IMHO.

Does DLS, SLS, melting point determination.

After-care support is good from Malvern.

Not used the Wyatt instrument.

HTH,

Dave

Dear Fellow Crystallographers

We are going to buy a DLS instrument to help us assess crystallizability
of our proteins. I would be grateful for any opinions - either
on this BB or in my mail box (in which case I'll keep them to myself,
naturally).

We have looked more closely at two instruments:

DynaPro NanoStar from Wyatt and
Zetasizer Micro V from Malvern

and both seem to be rather similar in terms of parameters and price.

I would appreciate user opinions as to the reliability,
ease of use or any features that make a given instrument
particularly suited for assessing biological samples.

Many thanks,

Wojtek
