o Dr. Shirley Malcom, born and raised in the segregated South more than 65 years ago, a career based
on her studies in science seemed even less likely than the launch of the Soviet’s Sputnik. But with Sputnik’s
success, the Space Race officially started and, in an instant, brought a laser-like focus to science education
and ways to deliver a proper response. Not long after, Dr. Malcom entered the picture.
Although black schools at the time received fewer dollars per student and did not have sufficient
resources to maintain their labs at a level equivalent to the white schools, Dr. Malcom found her way to the
University of Washington where she succeeded in obtaining a B.S. in spite of the difficulties of being an
African American woman in the field of science. From there she went on to earn a Ph.D. in ecology from
Penn State and held a faculty position at the University of North Carolina, Wilmington.
Dr. Malcom has served at the AAAS in multiple capacities, and is presently Head of the Directorate for
Education and Human Resources Programs. Nominated by President Clinton to the National Science Board, she
also held a position on his Committee of Advisors on Science and Technology. She is currently a member of the
Caltech Board of Trustees, a Regent of Morgan State University, and co-chair of the Gender Advisory Board of
the UN Commission on Science and Technology for Development. She has held numerous other positions of
distinction and is the principal author of The Double Bind: The Price of Being a MinorityWoman in Science.
Of her active career in science, Dr. Malcom says, “I guess I have become a poster child for taking
one’s science background and using that in many other ways: we ask questions; we try to under-
stand what we find; we consider what evidence we would need to confirm or refute hypotheses.
And that happens in whatever setting one finds oneself.”

AUTOMATED COMPOUND QUALITY CONTROL
The Brooks Plate Auditor is a fast, accurate, and noninvasive tool
for identi� cation of precipitate and empty wells in compound and
screening plates. The new Plate Auditor is the result of a success-
ful collaboration with the Scripps Research Institute. The new Plate
Auditor is designed to evaluate the quality of microplate-based com-
pound samples for precipitation and liquid volume prior to use in
compound management and high throughput screening activities.
The system rapidly analyzes plates to automatically verify sample
integrity thus eliminating the need for extensive manual quality con-
trol. The ability of the instrument to provide sample color information
makes the Plate Auditor a unique option for monitoring sample qual-
ity over time, and identifying wells with artifacts which may interfere
with or invalidate screening results.

ELECTROCOMPETENT CELLSCloneCatcher Gold DH5G Electrocompent E. coli cells exhibit ex-
tremely high electroporation ef� ciencies that approach the theoreti-
cal maximum of 3.4 x 1011 cfu/�g pUC19 DNA. Transferring exog-
enous DNA into E. coli is a standard laboratory method for cloning
genes and constructing cDNA, genomic, and epitope libraries. The
limiting factor in many library-screening efforts or multiple fragment
ligations is the ef� ciency by which DNA can be introduced into E.
coli. Electroporation is one method to ef� ciently introduce DNA into
E. coli. CloneCatcher Gold cells meet the needs of scientists that are
seeking to � nd rare clones or are building complex or metagenomic
libraries. CloneCatcher Gold signi� cantly outperforms all other com-
mercially available Electrocompetent Cells when introducing ligated
DNA. When the amount of input DNA is limited, CloneCatcher Gold
enhances your likelihood of success. CloneCatcher Gold requires
less topoisomerase-loaded vector and therefore can reduce the
overall operating costs.

HPLC COLUMNA new 5 �m particle has been added to the Kinetex core-shell prod-
uct line. As the largest diameter particle in the family, Kinetex 5 �m
core-shell columns deliver better performance than 3 �m or 5 �m ful-
ly porous offerings, with no increase in backpressure. In fact, the new
5 �m media provides 90% higher average ef� ciencies compared to
the same size fully porous columns and little to no method devel-
opment is required to achieve improved performance on standard
high-performance liquid chromatography (HPLC) systems. Chroma-
tographers can simply substitute these columns into reversed phase
HPLC methods that use traditional fully porous columns. Kinetex
5 �m delivers increased resolution and higher ef� ciencies and ex-
tends the scalability and portability of the product line. With the cur-
rent range of available particle sizes, including 1.3 �m, 1.7 �m, and
2.6 �m, the same method can be easily transferred from UHPLC to
HPLC to Preparative LC with Kinetex Core-Shell Technology

THERMAL TEST ENCLOSURES A line of thermal test enclosures for the ThermoJet ES precision
temperature cycling system is now available. The thermal enclo-
sures provide highly accurate testing and processing of temperature
sensitive electronic products. Available in either clamshell or hood
con� gurations, the thermal test enclosures may be used to isolate a
device under test (DUT) at a precise temperature insulated from ex-
ternal conditions, thereby providing the optimal conditions for highly
accurate testing. Maintaining a uniform stable temperature with re-
al-time thermal measurements on a DUT, the new thermal enclo-
sures deliver unmatched test accuracy and precision. The thermal
enclosures allow temperature testing of a variety of device sizes into
almost any test setup, enabling characterization, quali� cation, and
fault isolation on components or production level testing. All thermal
test enclosures are electrostatic discharge-free and/or electromag-
netic interference shielded.

ELECTRIC CAPPERDesigned to work with all sample storage 96-format tube and rack combinations,
without use of adapters, the Univo Electric Capper CP480 sets a new bench-
mark for ease of use, versatility, and speed of operation. Operating as a stand-
alone benchtop unit the compact Univo Electric Capper is able to uniformly cap a
complete rack of 96 sample storage tubes in only four to nine secondsóless than
half the time of competitive systems. The versatile Univo Electric Capper can cap
all Micronic plug style caps: capmats, capbands, and capclusters made of TPE,
EVA, or other materials on 96-format Micronic tubes and racks. The capper is also
compatible with most other brands of tubes and caps. The Univo Electric Cap-
per is extremely easy-to-use. For capping, simply place the rack � lled with tubes
in the sample holder and place a capmat, capband, or capcluster on the tubes.
