Laboratory Products 59 High Throughput Nanolitre Pipetting
200 platforms equipped with a variety of liquid handling arms. Material is often limited for compound screening, so we need to be able to pipette volumes down to 300 nl, and have invested in a new Freedom EVO platform optimised for this work.”
“Using the 15 µl tips, the new workstation’s MCA 384 can accurately and reproducibly pipette down to 300 nl without the need to use any special techniques. This allows us to reduce our assay volumes to just 30 µl while still maintaining a DMSO concentration of less than 1%. We control almost everything from Freedom EVOware®
, which is perfect for rapid, high throughput screening using fairly simple worklists, but still allows more complex
programming for assays where the timing is crucial. It gives us so much flexibility.”

Scientists working at the Leibniz-Institute for Molecular Pharmacology (FMP) in Berlin, Germany, are benefitting from the low volume pipetting capability of a MultiChannel Arm™ (MCA) 384 for siRNA and small molecule screening. Martin Neuenschwander, an automation scientist working in Dr Jens Peter von Kries’ Screening Unit at the FMP, explained: “We have been using laboratory automation for small molecule screens for several years, and have four Tecan Freedom EVO®
Compact Solution for Parallel Blending / Formulation Experiments
Asynt has developed a new adaption of its Vortex overhead stirrer, called the Vortex Blend, specifically to cater for the requirement of scientists who need to test new formulations and blends in parallel.
Many scientists in the oil, polymer, cosmetics and hygiene industries have established methods for blending and formulation development based upon mixing materials in standard laboratory beakers. These protocols often require heating and powerful mixing to ensure blend / formulation homogeneity. To accelerate formulation development it is advantageous to perform multiple blending experiments in parallel. Traditionally conducting multiple heating and overhead stirring experiments in parallel has taken up a lot of valuable fume hood space. Also when working in parallel it is important to ensure identical conditions are created in each beaker which is difficult when using multiple heater stirrer set-ups where motor speeds and heating rates may vary.
Developed by Asynt, in conjunction with a leading industrial formulation development group, the Vortex Blend offers scientists an efficient, space saving way of performing 3 blending experiments in parallel. Benefiting from a 3-way gearbox and integral heating plate – the Vortex Blend not only economises valuable lab space but also ensures that parallel experiments have identical stirring rate and heating rate/temperature conditions thereby improving result reliability. The Vortex Blend incorporates a standard overhead stirrer motor and hotplate for operation.

ADVERTORIAL There is an Easy Way to Control Climate Changes
Putting technology at the fingertips of researchers. Aralab’s new touch-screen ClimaPlus controller, integrated into all climatic chambers and controlled environment rooms, is a new step towards ease of use in climatic simulation, placing all environmental variables in an intuitive icon based interface for all programming, scheduling, and alarm functions.
Main chamber processes such as temperature, humidity, light intensity or CO2
the controller memory, as well as on the PC based software.
Adding external sensors or features such as air flow speed or automatic nurturing of plants is virtually automatic and all new functions become integrated on both the controller functions and controller memory. This will provide an increased capacity of research variables and information, ultimately improving the quality of all experiments.

Arctic Cold and Tropical Heat in the Same Controlled Environment
Aralab, a leading European manufacturer of climatic chambers and controlled environment rooms has introduced a new climatic chamber for Plant Research.
The new Aralab FITOCLIMA 2500 sets a new standard in controlled environments, introducing the ‘Auto-Defrost’ option, making it possible for researchers to work with full light intensities at negative temperatures without temperature defrost spikes.
Adding to the wide temperature and humidity ranges, light control was also improved with numerous lighting options that can increase research control and reduce operating costs. Examples: LED lights with fully adjustable spectral distribution or the most modern and energy efficient ceramic metal halide lamps, both providing more than 1.000µmoles/m²/s-1 (74.000 Lux) at 50cm from the lights.
Height adjustable shelves guarantee the optimal positioning of the specimens at any time during the experiment, also allowing for an efficient control of required light intensities.
