Heidolph rotovap: Removes solvent or other volatiles from a reaction mixture. A big advantage of this unit is that the control panel can be removed from the hood with the sash closed. All aspects of the rotovap can then be controlled from the safety of being behind the sash outside the hood.
Heidolph overhead mechanical stirrer: This is for when we really need to stir!
Mbraun glovebox: The glovebox uses a nitrogen atmosphere currently. This unit has a freezer, and a cold well filled with lab armor beads for doing chemistry at low temperatures inside the box.
Automatic polarimeter: This instrument determines the optical rotation of a solution containing a chiral compound or polymer. This is useful to estimate the enantiomeric excess of a small or large molecule.
ReactIR 15 in-situ FT-IR spectrometer: This is useful for monitoring epoxide and vinyl (co)polymerizations.
Heidolph stirring hotplates: Stirring and heating.
Custom glassware for polymerization: These reactors have heavy walls to handle high vapor pressure monomers, and a single standard port size for all connections of 3/8″ OD.
J.C. Meyer solvent system: This system contains THF, Toluene, Cyclohexane, DMF, Dichloromethane. We share with the Keitz lab who has a complementary set of solvents.
Labconco Lyophilizer (freeze dryer): For those times when you have a solution in water, but what you really want is a nice powder.
Polymer characterization–Molecular size distribution
GPC #1: Agilent 1260 Infinity I with Wyatt tRex, Dawn Helios, Viscostar detectors: Currently running chloroform (+stabilizer) mobile phase. Columns fluctuate depending on molecular weight range we are investigating. Wyatt detectors from wyatt.com!
GPC #2: Agilent 1260 Infinity II + MDS: (right) DMF mobile phase with LS, DLS, and RI detectors.
Polymer characterization–Physical/thermal/viscoelastic properties
Micrometrics Pycnometer: This instrument yields the density of solid samples. It is refreshingly easy to use.
Zeiss optical microscope with Linkam heating/cooling stage: Picture coming!
TA Ares 2000ex rheometer: Melt or solution viscoelasticity. This instrument has many tools that expand its functionality further.
BioLogic potentiostat (single channel): This is for conducting basic electrochemistry.
BioLogic impedance analyzer with heating stage: Measuring ionic conductivity and dielectric
