Array tests for common anthelmintic analytes
ANTHELMINTICS are drugs that are effective against tapeworms, liver flukes, round worms, and other internal animal parasites – known as the helminthic infections. The use of anthelmintic drugs can improve animal health and so boost livestock production, but regulatory agencies…
Control O2 and CO2 in the microplate reader
FULLY regulated independent control of oxygen (O2) and carbon dioxide (CO2) within a microplate reader is the promise made by BMG Labtech’s Atmospheric Control Unit (ACU). Available for the Omega microplate reader range, the microprocessor-controlled ACU offers dual independent control…
Lasers output 4W at 514nm
COHERENT says the newest members of its Genesis family of solid-state lasers are the first to offer multi-Watt output at 514nm. This makes them useful in life science applications such as fluorescence studies, and in bioinstrumentation. They are also useful…
Calibrating pipettes at 100 laboratories
ACCURATE pipette performance is vital to any laboratory, and can only be assured through regular calibration. This is essential not only for Good Laboratory Practice (GLP) and Good Manufacturing Practice (GMP) requirements, but for any quality assurance structure. Mettler Toledo…
Electrophoresis made easier
THE RANGE of electrophoresis products from Cleaver Scientific has been bossted with the addition of the MultiSub Midi 96, which allows direct loading from 96-well plates. Samples can be loaded from the plates using a standard eight-channel pipette, eliminating smple…
Optimised grinding of temperature-sensitive samples
THE COMMINUTION of difficult samples, like temperature-sensitive powder coatings and plastics, or materials with intrinsic moisture such as tea or herb leaves, can present a problem for some sample preparation mills. Fritsch says that its Pulverisette 14 variable high speed…
Automatic potency analysis from colony counter
SYNBIOSIS says its ProtoCol 3 colony counting and zone measurement system is the first to automatically generate antibiotic and vaccine potency analysis from count and zone data. ProtoCol 3 can read plates of 30-150mm, detecting colonies as small as 43…
Higher throughput for better H1N1 screening
THE LABORATORIES at Labor Krone and Imoltec (Bielefeld University of Applied Sciences), Germany, have taken delivery of a Thermo Scientific KingFisher Flex magnetic particle processor to enhance research into H1N1 screening. After the 2009 ‘swine flu’ pandemic (Influenza A H1N1),…
Enhanced lyophilisation with this condenser
GENEVAC promises a new benchmark for enhanced evaporation and lyophilisation with its new SuperCool 75 condenser, when used in conjunction with the HT-12 high throughput evaporator. Preparing dried powder samples from HPLC purification fractions is a routine laboratory task, and…
