Two new vacuum pumps for mass
spectrometer systems
Hena 50 (photo) and 70 are singlestage,
oil-sealed rotary vane pumps
that were developed for the demanding
requirements of mass spectrometer
systems. They achieve pumping
speeds of between 32 and 59 m3/h,
depending on their size and speed of
rotation. Their integrated oil-mist separator
ensures clean exhaust air. They
are equipped with a frequency converter
that enables them to be used
worldwide with single-phase input and
identical pump capacity for 50 and
60 Hz. A constantly high flowrate in
the target pressure range, adjustable
pumping speeds and low final vacuum
contribute to the instrument's reliable
high performance. Long maintenance
intervals and operating hours are ensured
by the high oil volume in the
pumps and their low oil temperature
during operation. - Pfeiffer Vacuum

Locating software includes
digital twin of performance
The new Location Intelligence software
(photo) expands the Simatic RTLS
(realtime locating system) platform to
include a digital twin of performance.
The web-based software analyzes and
visualizes dynamic data, processes
events, and can be addressed directly
from enterprise resource planning
(ERP) or manufacturing execution
system (MES) systems. The position
data provides the user with a comprehensive
overview of material flow,
order information or possible problem
areas. Depending on the process step
and order status, order information can
then be displayed on the Simatic RTLS
ePaper transponders, providing a paperless
solution. - Siemens Digital

Temperature control for the
semiconductor industry
The new Semistat series of thermoelectric
process thermostats (photo)
are used to control temperature in
etching processes in the semiconductor
industry. Semistat S 1200 is
an entry-level device that offers a
small footprint with a cooling output of
1.2 kW at 20°C. The Semistat S 2400
incorporates the latest innovations
from the thermoelectrics sector, including
high-performance Peltier elements,
which guarantee a higher power density
and greater reliability. The Semistat
4400, with 4.4-kW cooling output, is
designed for applications using 300mm
wafers with a high cooling-output
requirement at low temperatures. -

Durable analytical balances
provide improved safety features
The MS-TS analytical balance (photo)
features a robust full-metal housing, as
well as built-in quality-assurance and
safety features designed for shared
laboratory equipment. In addition to
being easy-to-clean, the MS-TS offers
Glove Mode, which makes the touchscreen
even more sensitive and easy to
navigate through gloves, reducing the
risk of exposure to aggressive materials.
Multiple interface options make it
easy to manage data, and with the addition
of EasyDirect data-management
software, users can collect data from
up to 10 balances simultaneously for
fast, error-free reporting and enhanced
regulatory compliance. - Mettler
Toledo GmbH, Greifensee, Switzerland

This pilot-scale mixer
has been redesigned
The newly redesigned RS-02 highshear
pilot-scale mixer (photo) is well
suited for pilot plants and small-scale
production, including product development,
formula optimization and trial
mixtures. The RS-02 redesign includes
a mobile lift stand with a wider base for
added stability and a hand crank for adjusting
mixer height. The portable unit
fits through standard-width doorways,
making it easier to transport it within a
plant. The RS-02 has a batch capacity
of 5 to 20 gal and incorporates the
patented Rotosolver high-shear mixing
impeller to provide balance between
shear and flow so that mixtures are
completely homogenous, emulsified
and agglomerate-free. - Admix, Inc.,
