Polymer and Protein Molecular
Weight Analyzer
The BI-MwA Molecular Weight Analyzer
from Testa Analytical Solutions is a high-
performance tool for studying synthetic
and natural polymers in solution as well
as investigating protein aggregation,
oligomerization, and complex formation.
Employing a 30-mW, 660-nm diode laser, the
BI-MwA uses seven angles to determine the intensity of scattered
light as a function of angle and polymer concentration. Using this
information, the system software can quickly produce Zimm, Berry,
and Debye plots from which weight average molecular weight (Mw),

chromatography (GPC/SEC) system, or for following the kinetics of
polymerization using the tunable diode laser absorption spectroscopy
(TDLAS) technique.

customized for more rapid heating and/or multiple temperature zones.
Several options are available, ranging from facilities for internal cell
measurement, to sealed sample/additions valves, condenser jackets,
electrical heating options, liquid charging systems, gas supply/mixing
systems, air-driven stirrers, purged heating chambers, and more.
Drawing upon skilled United Kingdom craftsmen, Asynt can also build
these reactors from alternative materials, such as Hastelloy, Inconel,
titanium, and alloy steels, allowing for greater heat capacity and use with
particularly corrosive or caustic chemicals.

Human pluripotent stem cells (hPSCs), including embryonic
and induced pluripotent stem cells, acquire recurrent genetic
abnormalities during prolonged culturing. These karyotypic
abnormalities can alter the behavior of stem cells, jeopardizing the
validity of a disease model, drug screen, or cell therapy. The hPSC
Genetic Analysis Kit from STEMCELL Technologies contains all required

a wide range of applications. Easy-defrost condensers enable fast
turnaround between runs. A choice of condenser capacities of 35 L or
50 L allows you to select a high shelf-surface-to-condenser-surface ratio,
which is most suitable for freeze-drying products requiring a very large
amount of shelf area but containing less solvent, as is the case with many
diagnostic kits and tissue-banking applications.

- Automated Rotary Vial Washer
SP PennTechís RW-500 rotary vial washer is a small, automated system
designed for low-to-medium output pharmaceutical and biotech
applications. This washer has only two moving parts inside the washing
chamber, and does not use needles, minimizing the chance of glassware
damage and the possibility of a U.S. Food and Drug Administration (FDA)
483 notice for a product containing unintended particulates. Suitable
