Surplus Equipment

Seeking new homes for surplus equipment

The UChicago Chemistry NMR Facility has a fair amount of equipment that is no longer compatible with our current equipment or research aims. We seek to direct it away from the e-waste stream and toward laboratories that can make good use of it. On this page, we post equipment that can be picked up for free by appointment with the facility manager.

Alternative channels:

To give these items greater visibility, we will post them on Rheaply and eBay.

Rheaply – we use this service to post items of general interest, like monitors, crates, furniture, etc. to a campus audience, and perhaps to greater Chicagoland. This will not include items with such specific technical requirements that we know is must be visible to a national or global technical community.
eBay – we use the channel when items are likely to need to be shipped, and when they are highly technical in nature and need a very large audience to locate the limited number of interested parties.

ALL SURPLUS EQUIPMENT IS DISTRIBUTED AS IS
!! NO GUARANTEES OF PERFORMANCE !!

CURRENTLY AVAILABLE:

Magnets – late 1980s vintage

AVAILABLE for unintended purposes: two late-1980s-vintage Oxford magnets that have been in storage for about 15 years. We need these out of the storage room ASAP, so they will go for free to the first person/people who commit to driving up to our dock and taking them away.

Oxford 300 widebore, presumably unshielded. Magnet book (recently discovered) says it was energized in 1988.
Oxford 400 narrowbore, presumably unshielded, presumably same vintage as the 300. Magnet book location unknown.

These magnets are most probably NOT recoverable for NMR use:

Simple cost/benefit analysis of restoring one is surely higher than the cost of a regular used magnet
Helium consumption of one must be higher than a relatively modern magnet
Lack of shielding poses site problems
Neither magnet appears to have been secured with shipping restraints. The people working through the stuff in the storage room thought the magnets had liquid in them because they “sloshed” when shoved. I’ve found a few objects in odd boxes that appear to be restraints, but I’m sure it’s not a complete set.
The widebore suffered some water damage from the top during its time in storage.

NMR Probes

We have a number of probes for 5mm-diameter liquids/solution samples, and one for 7mm solids samples.

SOLIDS: Bruker 300 MHz widebore HXY MAS 7mm solids probe with VT control. Top-loading, includes transport tube. Includes four extra tuning modules. See folder “UChi1_300widebore_HXYprobe7mm” for photos. SN B0620/035.
LIQ: Bruker 300 MHz BBO, 5mm, manual tune, no gradient, no VT heater but dewar look OK – BONUS: adapter set for widebore magnet. See folder “UChi02_300Liq_BBO_WideboreAdapt_5mm_Manual” for photos. SN Z3150/0020.
LIQ: (Beautiful) Cryomagnetic Systems 500 MHz BBO, 10mm, manual tune (<< with long separate tuning rods – included! >>), VT seems OK. See folder “UChi03_500Liq_BBO_10mm_Manual_Cryomag” for photos. SN HR-50/94.
LIQ: Bruker 500 MHz 1H-only Z-grad 5mm probe with working (probably) VT control – glass insert is loose. Even if not fixed, good as prop for teaching probe architecture. See folder “UChi04_500liq_1Honly-Z_5mm_Manual-LooseInsert” for photos.SN Z8479/004.
LIQ: Cryomagnetic Systems 500 MHz 1H-only, no decouple, 5mm manual tune (requires separate long tuning drivers, which are missing), no gradient. See folder “UChi05_500Liq_1Honly_5mm_Manual_Cryomag” for photos. SN HR-44/7.
LIQ: Bruker 500 MHz BBI Z-grad 5mm probe with broken VT dewar. Even if not fixed, good as prop for teaching probe architecture. see folder “UChi06_500Liq_BBI-Z_5mm_Manual-brokenVT” for photos. SN Z8375/0008.
LIQ: Cryomagnetic Systems 400 MHz 19F w/ 1Hdec 10mm manual tune (requires separate long tuning drivers, which are missing), no gradient, VT seems OK. See folder “UChi07_400Liq_19F-1Hdec_10mm_Manual_Cryomag” for photos. SN HR-50/112.
