Lab and Fume Hoods
The group's research is performed in a 2000 ft2
(200 m2) state-of-the-art lab-space. Each group member performs
his or her tasks in a six foot wide fume hood (left). Safety is our primary
concern: all chemicals are stored in cabinets (middle) with liquid compounds
placed in plastic containers. Solvents and odorous compounds are stored in
special ventilated cabinets (right).
GC/MS
and Chiral GC
Our group owns a Hewlett Packard GC/MS system:
a 6890 plus GC system combined with a 5973 mass
selective detector. The MSD is capable of detecting mass from 1.6 to 800 amu.
The GC system is comprised of two capillary columns, with an FID detector
available on the second column. The system also utilizes an HP 7683
automatic injector, which
can accommodate up to 8 samples providing perfect reproducibility of
retention times. The system
includes Agilent's ChemStation to analyze and display sample results as well as
a database which has over 150,000 mass spectra of known compounds. In addition,
the group owns a HP 5890 GC system equipped with a chiral column.

Solvent purification system
Our new solvent
purification system allows to produce up to four anhydrous solvents and keep
them at oxygen-free conditions ready for immediate use.

FT-IR

The group has a Nicolet 800 FT-IR, used to record infrared spectra in the range of 400 to 4000
cm-1.
UV-Vis

For recording spectra in the UV
and visible regions, we have a Hitachi U-2000 UV-Vis spectrophotometer that
works in the range 1100 to 190 nm.
HPLC
In addition to GC/MS for column chromatography, our lab
also has three HPLC systems. The Hitachi system is composed of an L-4000 UV detector,
an L-6200 Intelligent Pump, and an HP 3395 integrator. The HPLC setup for
normal phase separation of relatively low polarity compounds. The second
HPLC system is setup for reverse phase separation of polar compounds.
Additionally, we have assembled a third HPLC system, equipped with a chiral
column.
Glove Box
For working with various
hygroscopic and other air-sensitive chemicals. The glove box is a 60 cubic foot, argon filled apparatus designed to
keep chemicals isolated from oxygen, moisture, and other unwanted
nuisances. The box is equipped with a Sartorius analytical balance, IKA
magnetic stirrer, a vacuum pump inlet, two side chambers (one for large
unit entry, one for small), a Plexiglas clear window in the front, and two pairs of
thick rubber gloves to allow the user to work within the box, all of which is necessary
for synthetic operation within the glove box.

Rotary Evaporators
The group also possesses 7 rotary evaporators, which means
there is a rotovap for every two people. Each unit is equipped with a variable temperature water
bath and a 10 Torr teflon vacuum pump. The
rotovaps allow for the rapid evaporation of solvents off of nonvolatile
compounds. To increase lab safety, each system is equipped with an
additional condensation system for the evaporated solvent and all vapors not
condensed are disposed of into fume hood.
Kugelrohr
The group owns a B-580 Buchi glass oven
distillation apparatus, also known as a kugelrohr. The unit is comprised
of the glass oven, a series of bulbs for distillations, a rotary unit for the
rotation of these bulbs, and a vacuum adapter to perform distillations at
reduced pressures. The kugelrohr is used in the distillation of small
amounts of compounds, where a simple distillation apparatus would be inefficient
at best. Using various vacuum pumps connected to the unit, far more
effective distillations may be performed on small scale.

Fraction Collectors
To aid in the collection of samples from chromatography
columns, we have several fraction collectors. The machines are programmed
to change test tubes automatically, allowing for other tasks to be performed
while running the column.

Thermostate
The VWR thermostate allows for the
maintaining of temperature reactions, both inside the thermostate and in the
external reaction vessel, in the interval of -26°C to 260°C with an accuracy
of 0.1°C.

Syringe Pump
The pump can accommodate variable sizes of syringes and possesses
the ability to control the actual rate that the liquid is added.
This is extremely useful for the slow addition of reactants to preserve an
essential excess of one reactant versus another or to maintain extremely low
concentrations of substrates.

Balances
In addition to regular lab balances, the
group also has a Sartorius BP211 D analytical balance
capable of measuring masses up to 210g. The model has an accuracy of 0.01mg
up to 80g and 0.1mg up to 210g. We also have an Ohaus analytical balance
with 0.1mg accuracy and can measure masses up to 120g.
Coffee Makers
Perhaps the most important and most frequently used piece
of equipment in our chemistry lab is the coffee maker. Fortunately,
should tragedy one day strike our coffee maker, we also have an espresso maker
as well. Also available are refrigerators, microwaves and water boilers, all
invaluable
pieces of machinery, as well.
