Telescope Spectrograph Optics
Benefiting from a unique facil-
ity where temperatures remain
constant year-round and vibration
is practically nonexistent, Optical
Surfaces is able to routinely pro-
duce and test demanding telescope
spectrograph optics (aspheres, flats, lenses, mirrors, and prisms)
that stretch the limits of conventional optical fabrication techniques.
Using a spectrograph, researchers can study the chemical and physi-
cal conditions that exist in a cross-section of space. Combined with a
land- or space-based telescope, a spectrograph can reveal valuable
information about the spectral distribution of light from a distant
astronomical object. Optical Surfaces maintains a range of interfer-
ometers that allow one-to-one testing of even the largest-diameter
spectrograph optics. Topographic and fringe analysis provides
precise testing of surface roughness and confirms the wavefront of
various surface forms. Operating a rolling program for calibration of
test optics (where possible) to national standards and production ap-
proval to ISO 9001-2015 ensures that our optics are second to none.

Instead of using aluminum foil or plastic wrap to cap beakers and
flasks, scientists can now use KIMBLE Silicone Lids. The lids stretch
and conform to beaker tops for a tight, secure seal providing a safer
closure. Available in three sizes and colors, the user-friendly lids fit on
beakers, flasks, bottles, and cylinders. The stretchy silicone material
creates a seal on spouts, beaded tops, or threaded necks on glass or
plastic vessels. Resistant to heat and chemicals, the lids are designed
with tabs so they are easy to put on or take off, even when wearing
gloves. Dishwasher-safe and reusable, the lids are a popular, sustain-
able solution for environmentally conscious labs.

dwk.com/colorsplashVacuum Ultraviolet Spectroscopy Workstation
McPherson offers two new deep-UV spectroscopy workstations to facili-
tate teaching and experimentation in vacuum and ultraviolet physics.
The workstations are ideal for spectroscopy experiments in the vacuum
ultraviolet regime, potentially advancing quantum information science
and engineering. There are two experimental kits available: diagnostic
and analytical. The diagnostic system equips the spectrometer with
a sensitive charge-coupled device (CCD) detector and can be used to
measure spectral emission of laser interaction, high-harmonic genera-
tion, plasma formation, luminescence, and fluorescence. The analytical
system comes with a tunable deep-UV light source, rather than the
CCD detector, and is ready to explore Einstein’s photoelectric effect,
one of the earliest predictions of quantum physics. The configuration
is also good for measuring transmission, photocathode response,
and reflection. Key features of these workstations include a versatile
and convenient spectrometer; filters; an open-concept, high-vacuum
sample chamber with a built-in optical breadboard; and an easy-to-
use vacuum pumping system. Systems may also have a deep-UV light
source. Students and experienced researchers will have more time to
consider setups and interpret results when using these systems.

The Thermo Scientific ALPS 5000 has been developed to increase
the efficiency of the heat plate-sealing process and offers maximum
flexibility to support high-throughput applications, from polymerase
chain reaction and high-performance liquid chromatography to NGS,
compound storage, and flow cytometry. It facilitates easy, tool-free foil
loading and does not require the use of adapters to change between
different plates. The system is operated via a large, intuitive touch-
screen with a modern user interface that allows for precise control over
sealing parameters, ensuring repeatability while including program-
ming parameters for integration into automation or robotic workflows.
Users can program sealing time, temperature, and pressure param-
eters to suit their specific requirements. The instrument offers fast seal-
ing times of up to four plates per min and features a compact footprint
to save valuable bench space. Furthermore, the ALPS 5000 has been
equipped with an Eco Mode, which triggers a temperature reduction
down to 30°C when the system has been inactive for a prespecified
amount of time, allowing for considerable energy savings.

Quantification of biotin after biotinylation of antibodies (or other pro-
teins of interest) can be an important step for development, manufac-
turing, or quality control of immunoassays. Traditional biotin quantifi-
cation methods, such as the HABA (4’-hydroxyazobenzene-2-carboxylic
acid) assay, suffer from long and complex hands-on protocols as well as
accuracy and reproducibility issues. The Biotin Q Conjugation Kit (with
inbuilt quantification) from Expedeon provides immunoassay develop-
ers with a short and simple hands-off protocol, along with accurate
and reproducible measurements. Spectrophotometric readings can be
made directly on conjugated antibodies or other proteins of interest
after biotinylation.

The new UltraVap Mistral XT 150 from Porvair Sciences provides
unmatched, automated drydown of organic solvent-based samples
in tubes and microplates up to 150 mm in length. Designed for easy
integration with linear laboratory robots, the workstation uses a sample
shuttle that can serve and retrieve long tubes or microplates from the
deck of Perkin Elmer, Tecan, Hamilton, and Beckman liquid handlers.
Controlled via an intuitive color touchscreen, the XT 150 comes com-
plete with clear safety side screens and full integral fume management.
Installation requires only connection to a gas supply and mains electric-
ity. Safety of solvent removal operation is ensured, as this compact,
CE-marked unit fits into all fume cupboards.
