2nd hand magnet(s) wanted

The NMR group in the Institut de Physique des Nanostructures would like to acquire one or more 200 or 300 MHz 89-mm bore magnets, manufactured by Oxford Instruments, and housed in so-called "family-type" cryostats. the characteristic of these cryostats is a bore tube length of 880 mm (all other magnet cryostats are clearly higher).
magnet accessories (current leads, shorting plug, transfer line) preferably included. power supply optional. no probes or RT shims.
if you have any available for sale, pls. contact
arnaud.comment@epfl.ch
or
jacques.vanderklink@epfl.ch
with an indication of the wanted price.
thanks.

Two Oxford, 89mm bore superconducting magnets for sale

We have two Oxford, 89mm bore superconducting magnets for sale,

- 200MHz decommissioned by Magnex but fully operational until 2007 (with stand and some optional Bruker MAS probes); and,
- 400MHz at field (with stand, some optional MAS probes and CMX 2-channel console items).

No formal guarantee can be given about any of these items.

If you have an interest in one or both of them, please contact me by email initially, and before September 26th.

Shipping and decommissioning can be arranged, but recipient will need to pay these costs. Viewing and inspections welcomed.

The University reserves the right not to sell or dispose of these items to any interested party if it so wishes without disclosure of the reasons, and no formal guarantees or future liability of the use of the equipment can be given about the condition or performance any of these items. The full regulations about sale, liability and disposal are available on request.

Avance 800MHz for sale

The Laboratoire de Chimie et Biologie Structurales (ICSN-CNRS) in Gif sur Yvette (France) is currently installing a new 950MHz Bruker spectrometer. Because of site setting requirements, we have to upgrade our 800MHz Bruker machine to an ultrashielded version.

Our current Avance 800MHz spectrometer (installed 02/1998 and equipped with a cryoprobe refurbished in 2007) is thus available for sale.

Wanted: Bruker micro-imaging probe

Folks,

We have an ancient, highly-modified, Bruker micro-imaging probe here that is
used in a 4.7T WB system.

This is the type of micro-imaging probe that took only 30 or 40 Amps max,
had air-cooling only (not water), and most importantly, had 8 electrical
connecting pins at the bottom of the gradient set, in 2 rows of 4, that
pushed down into a green block with 8 holes with electrical compression
fittings in it - which connected to the plug at the bottom of the probe
body, and from there to the gradient amps. These probes were in use in the
mid-1990's - not sure when they were discontinued.

Our probe-body has been in poor shape for a long time, and the cylindrical
fittings have been getting pushed out of the green block each time the
gradient set is inserted. Eventually, some wires gave way on the bottom of
the cylindrical connectors, and now we're down to a 2-axis gradient set.
Attempted in-house repair has only made the situation worse.


I was wondering if anyone has such an old probe-body lying around, no longer
in use? I know the gradient sets used to burn out fairly easily, so maybe
there are a couple of these in closets somewhere with no gradient set to
attach to it?

Alterantively, if you have a complete set of probe body plus gradients, let
me know. I realize the gradients are probably of no use without the probe
body. But if you stopped using your micro-imaging probe after upgrading to a
micro2.5 or Bruker's newer 60 Amp PSU's and have no use for the older probe,
we might be able to buy it for a nominal fee. We don't need RF coils - as
we do a lot of wierd X-nuclei at strange frequencies, so it doesn't matter
if the 1H coils in the probe are not 200 MHz!

I have photos of our probe and connectors, and can email them to anyone who
is not sure if they have what we're looking for!

Many Thanks,

Ross Mair
