also provides remote system monitoring via
smartphones, tablets or any Web-enabled
device, increasing walk-away time for
overnight and weekend runs.
Dimethyl sulfoxide (DMSO) is a solvent widely used for storage
and transfer of small-mo-lecular compounds during
campaigns in drug discovery.
Because of its unique physical
properties, DMSO behaves
differently than water
when handled by
and acoustic droplet ejectors.
Artel, Westbrook, Maine, has
recently introduced two new
reagent solutions that expand
the volume range measureable
with the company’s line of
DMSO products. For use with the company’s MVS Multichannel Verification System and Liquid Handler Performance Verification Service,
the reagents enable users to accurately calibrate and verify their liquid
handlers when dispensing DMSO-based solutions. The MVS is an easy-to-use, universal system that verifies the volume-transfer performance of
automated liquid handling systems and multi-channel handheld pipettes.
It consists of equipment, software, sample solutions and highly characterized microtiter plates.
An automated way to add sample
Autosamplers are another type of laboratory instrumentation used to
automatically introduce a sample into gas or liquid chromatographs,
titrators, density meters and refractometers for testing. Mettler Toledo,
Columbus, Ohio, recently introduced the InMotion autosampler, a flexible
and efficient automated sample changer for titrators, density meters and
refractometers. Designed for maximum throughput without sacrificing
space, the autosamplers improve the productivity of various laboratory
tasks. The Flex and Pro series are 42 cm wide, and the Max series can handle more than 300 samples on a 57-cm-wide sample rack.
InMotion autosamplers perform a variety of testing, cleaning and conditioning processes. Users can eliminate sample carry over with the Pow-erShower rinse system. Subsequent simultaneous titrations can be performed with the T90 Excellence titrator and a second tower for enhanced
efficiency. LED status lights on the top of the tower allow for quick status
confirmation from across a laboratory. In addition to automatically adding and removing reagents with a wide range of pumps and functions, the
autosampler offers tailoring to sample processing. The CoverUp protects
operators from volatile solvents and reagents, and waterbath racks temperate the sample rack.
Making simple tasks, simpler
Even simple laboratory tasks such as capping and de-capping bottles and
de-lidding and re-lidding plates, as well as plate stacking, can be strenuous
to laboratory personnel. When done for long periods of time manually,
For everyday capping and de-capping of bottles, Dispense Works,
McHenry, Ill., has introduced the Ring Dex filling and capping system.
Compact to save bench space, the system features a true file-based con-
trol system requiring no PC for operation. Setup of fill volumes, capping
torques and check weights is done with pre-programmed graphical
interface screens. Production dates for each container are time and date
stamped with each container’s fill weight. The history file may be upload-
ed for documentation and reporting requirements. The system also fea-
tures an on-board calibration routine.
