Computerised control of optical components

The analy-SIS bx and ix control modules are an asset to support microscopy on the BX61 and IX 81.

Ultra-thin-layer chromatography plates

The new era of chromatographic separation started with Chromolith HPLC columns. Now Merck's latest innovation in monolithic silica technology is the ultra-thin-layer chromatography plates (UTLC).

Enhanced microbial identification

To complement the existing databases of the MicroStation system, Oxoid has introduced two new MicroLog database products to the UK.

Integration of lab informatics leads to improved process automation

A fully bi-directional communication protocol between the commercial laboratory information management system and the process information management system or enterprise resource planning system would ensure end-users total independence, but with the ability to share appropriate data. Nick Arnold explains.

Autoclavable multi-fermentor system

BIOSTAT B-DCU is the latest addition to the range of fermentation systems supplied by B Braun Biotech International.

Sample purification kits for mRNA and protein

Now available from Bio-Nobile Oy is a range of kits for the purification of nucleic acids and proteins, based on BN's magnetic particle separation technology.

Microscopes have 3000 Pa pressure range

Leo Electron Microscopy develops, manufactures and distributes worldwide electron microscopes and focused ion beam systems.

Use of hydrogen generators to supply the gas for laboratory use is on the increase

The use of hydrogen generators to supply hydrogen for laboratory use is becoming increasingly widespread.

Ultrasonic spectroscopy moves into laboratory for dynamic monitoring

Ultrasonic spectroscopy is all set to become a routine analytical technique in the laboratory. It provides a non-destructive way to measure the properties of materials, using sound waves rather than the more usual electromagnetic waves. As Vitaly Buckin and Breda O'Driscoll show, it can also be used for monitoring the course of dynamic processes such as biochemical reactions.

"Modular HPLC system offers flexibility, reliability and sensitivity"

Users of HPLC instrumentation require a vast array of features and working specifications to meet their application requirement.

clean room reaction monitoring

A Camspec M400PC diode-array fibre-optic spectrophotometer is helping NanoMagnetics develop new technology in the field of magnetic storage devices.

ICP-OES allows for sensitive analysis of organic samples

Dirk Ardelt, George Glavin, Sergej Leikin and Henk Visser look at the use of inductively coupled plasma-optical emission spectroscopy and the potential difficulties in its use in analysing organic samples.

system integration reduces costs

Whoever wants to maintain their competitive capacity today has to consider the complete flow of processes in the company, organising the areas adevelop-make-sell' as efficiently as possible.

Affinity chromatography is vital to protein research and development

Because they are derived from living organisms, biological products present a potential source of pathogens. By John M. Curling.

New references assist validation in far ultra violet spectroscopy

John P Hammond reports on new certified reference materials for the determination of wavelength and photometric accuracy in far UV spectrophotometry.

Harnessing new technologies for more powerful bioassays

Bioassays are becoming ever more powerful. Among the latest developments are a micro-sonicator capable of lysing difficult cells such as anthrax spores, and an ultra high throughput screening technique which allows one operator to perform a million assays every day.

Automatic resin and powder dispensing

Automated resin and powder dispensing is extremely useful for dispensing resins for combinatorial chemistry, scavenger resins, powders such as freeze dried antibodies, solid phase separation materials and magnetic beads for purification.

Genotypic analysis of HIV-1 drug resistance mutations

Sven Thamm looks at a fully integrated and complete solution for detecting and reporting HIV-1 resistance to specific anti-retroviral therapy.

chemicals catalogue

The new Fisher Scientific Chemicals catalogue lists more than 5000 chemicals for the analytical chemist. This edition combines the strengths of the production facility of Fisher UK and the expertise in distribution of the Acros Organics facility in Geel.

Special titration PC software released to comply with FDA requirements

The need for pharmaceutical laboratories to comply with Title21 of the Code of Federal Regulations Part11 is an increasingly important issue. It generates many requests for a21CFRPart11 compliant' software, despite the fact it is the laboratory that has to be in compliance with the regulations, rather than the software.
