Genevac, world leaders in solvent removal technology, has over 20 year’s experience of supplying evaporators for removal of solvents from oil, fat and fuel samples.
Oils, fats and fuels are normally isolated from natural sources using extraction or separation techniques that present the final sample in a solution of organic solvent. Before analysis such samples must be dried or concentrated. Whether extracting and recovering additives, evaluating lipid content of foods, characterising reclaimed cooking oils before reprocessing / conversion to biofuels, or investigating drillling test samples - oils, fuels and fats can often prove difficult to dry without using very high temperatures which may lead to loss of the more volatile fractions within the sample....
Read MoreNew Opportunities in Cancer Research Created By Extracellular MatrixMar 7, 2013
A new white paper, available from AMSBIO, discusses the latest developments in extracellular matrix (ECM) and the opportunities they offer in cancer research
At least 80% of cancers are carcinomas, or tumours of the epithelia. Traditionally, cell transformation to a cancerous stage has been evaluated by anchorage dependent growth. More recently, the role of the extracellular matrix, already established in normal epithelial biology, has come to the fore in the study of carcinomas. The extracellular matrix is largely composed of several protein families, notably laminins, collagens and fibronectin. AMSBIO's new white paper focuses on ECM proteins most relevant to cancer research and their use in the oncology field...

Pipetting is a forceful and repetitive activity, and it is now widely accepted that there is a strong association between pipetting forces and the occurrence of developing Repetitive Strain Injuries (RSI's). In fact, pipetting for just over an hour a day over the course of a year is enough to put you at risk, and these risks tend to increase with workload and age. But for most scientists pipetting is an unavoidable daily task, so reducing or even preventing your risk of RSI should be high on your list of priorities. The best way to start protecting yourself is by ensuring you have all the correct facts and advice available about which conditions pose or increase your risk...
METTLER TOLEDO today announced the release of a white paper on the topic of gravimetric sample preparation. It compares the advantages and disadvantages of gravimetric vs. volumetric sample preparation methods, with particular reference to recognizing and acting to reduce errors associated with each step in the sample preparation workflow
Anyone working in a regulated analytical laboratory or a Quality Assurance (QA) / Quality Control (QC) environment will identify with the potentially costly and time-consuming process of investigating Out-of-Specification (OOS) results. More than 50% of OOS results in analytical workflows are reportedly caused by sample processing and operator errors. Implementing automated Gravimetric Sample Preparation and following Good Weighing Practice™ (GWP®) can help reduce data variability and OOS results.

Read MoreMalvern Instruments introduces DLS MicrorheologyOct 10, 2012
New Zetasizer Nano ZSP offers emerging rheology technique for weakly structured fluids
With the recent launch of the new top of the range Zetasizer Nano ZSP system, Malvern Instruments has added dynamic light scattering (DLS) Microrheology to its portfolio of materials characterization techniques. To introduce this powerful technique, the company has published an in-depth paper that explains the background to microrheology, and how it can be used to investigate the rheological properties of even the most weakly structured fluids, using sample volumes on the microliter scale. ‘An Introduction to DLS Microrheology’ includes data for protein (bovine serum albumin (BSA)) and polyethylene oxide (PEO) solutions that illustrate the significance and usefulness of the method. It is freely available from the Malvern website.
As science evolves, new technologies and methods are continuously created that supplant older, outdated methods. The main reasons to replace outdated applications are: to save money, to save time, and to be safer. If a new application can do all three, its chance of successfully replacing an older technology greatly increases
In the last decade, the microplate reader has become a multi-mode, multi-functional instrument that is used routinely in most laboratories.

Read MoreImproved cryopreservation of human hepatocytesAug 13, 2012A recently published article from researchers at the Karolinska Institute details an improved protocol for cryopreservation of primary human hepatocyte using STEM-CELLBANKER® cryopreservation solution from AMSBIO.
In the article the authors compare cryopreservation of liver hepatocytes using STEM-CELLBANKER with the frequently used DMSO-University of Wisconsin (DMSO-UW) medium protocol. Both protocols yielded hepatocytes with good P450 function, however, the STEM-CELLBANKER protocol gave a higher viability than the DMSO-UW cryoprotectant. The researchers concluded that STEM-CELLBANKER beneficially is also xeno-free and will be applicable to cryopreservation of clinical-grade primary human hepatocytes...
