Laboratory Products 55 Unite 3 Measuring Tasks in 1 Instrument
The Easy VIS, one of the next-generation EasyPlus UV/VIS spectrophotometers produced by Mettler-Toledo, takes over the measuring tasks of up to three instruments: a colorimeter, a spectrophotometer, and special measuring methods for water testing, such as titration. All this power rests in one instrument about the size of a notebook. The results appear on screen in trustworthy accuracy, precision, and repeatability - within seconds. That saves money, time, and space.
A typical place for Easy VIS is the QC lab at small manufacturers in the food and beverage industry, environmental testing labs, or any industry needing quality control and supervising their process- or wastewaters. The Easy VIS is used during multiple steps of the production process: For inspection of raw materials, quality control of semi-finished and finished products, or testing the water quality of wastewater.
The visual user interface with workflow guidance allows you to simply scan and measure. Even untrained staff can operate Easy VIS intuitively. This increases the integrity and repeatability of the analysis and saves training time.
Easy VIS operates within a wavelength range of 330 to 1,000 nm. The light source is an easy-to-replace tungsten lamp, which any operator can replace within no time.
The partner device, Easy UV, covers the full UV/Vis spectrum with a wavelength range from 190 to 1,000 nm to cover additional applications in the UV range. Plus: The Easy UV runs with a power-saving and maintenance-free xenon-flash lamp.
25 standard-compliant colour scales in the visible range come pre-installed and can easily be used. Some examples are ICUMSA™ for sugar colour, ESBC for beer quality analysis, or OIV CIELab for wine colour determination. The results reveal the quality of the product within seconds.
Water analysis shows, for example, the concentration of Aluminium, Ozone, Chlorine, or Polyphenol. This reveals whether the water is fit for human consumption or can be used in further production. Is the wastewater safe to release? With its numerous built-in water testing methods, the spectrophotometer can quickly provide the answer.
For spectrophotometry, the sample is analysed at the wavelengths where the sample has its characteristic absorption of light. The Easy VIS measures the transmitted or absorbed light and the reading reveals the sample’s concentration or purity.

Virus-based Tools for Cell Engineering
Multiple Independent Studies Demonstrate Superiority of Legionella pneumophila Detection Method
The IDEXX Legiolert test is a liquid culture method designed to be highly sensitive for Legionella pneumophila, and significantly easier to perform than ISO 11731 and other traditional BCYE solid culture methods.
Legiolert has been extensively compared to traditional culture methods. There are currently 11 peer-reviewed comparison studies that have evaluated over 2,000 environmental samples taken from all over the world. Nineteen different laboratories across 7 countries were involved in these studies, including the Istituto Superiore di Sanità, the US Environmental Protection Agency, as well as public and private laboratories.
All of the peer-reviewed research showed Legiolert to be at least as sensitive as BCYE solid culture methods, with 9 of the 11 studies showing it to be statistically more sensitive. All of the studies showed Legiolert to be highly specific for the detection of Legionella pneumophila.
AMSBIO has added a new range of Vesicular Stomatitis Virus (VSV) to its suite of virus-based tools for cell engineering and the study of viral infection.
Vesicular Stomatitis Virus is an enveloped, negative-stranded RNA virus with a simple structure. Its ability to infect a wide range of mammalian cell types has made it a valuable tool to study virus entry, replication, and assembly. A key advantage of the AMSBIO VSV model is that it undergoes only one round of replication. Consequently, it is safe to use and requires only a biosafety level 2 facility.
VSV vectors offer a robust model of viral infection that can be efficiently pseudo typed with envelope glycoproteins derived from heterologous viruses, making them highly suitable for studying the entry mechanisms of such high-risk viruses.
Drawing upon proprietary technologies and reagents, recombinant VSV vectors from AMSBIO benefit from top quality production protocols that deliver products unmatched in terms in terms of titer, purity, viability and consistency.
Recombinant VSV vectors from AMSBIO are the viral product of choice for a growing variety of applications including studying mechanisms of viral entry into host cells, identification of cellular receptors used by viruses for cell entry, screening of viral entry inhibitors and vaccine development research.

This independent research is supported by a number of certification and regulatory bodies: the method has been published by ASTM International as ‘ASTM D8429-21: Standard Test Method for Legionella pneumophila in Water Samples Using Legiolert’; is specified as a recommended method in the by the UK’s Standing Committee of Analysts’ ‘blue book’ publication, ‘The determination of Legionella bacteria in waters and other environmental samples (2020) – Part 2 – Culture Methods for their detection and enumeration’; and Legiolert is also recognised with AFNOR certification for hot and cold sanitary water and cooling tower water (Reference No IDX 33/06 06/19).

Enhanced Laboratory Safety with Instant Liquid Waste
Disposal Autoclaves Autoclaving hazardous used liquids provides the ultimate method for waste sterilisation, but is not without its flaws. To run efficiently, an autoclave must be run with a full load, which in turn requires liquid biohazards to be stored until there is sufficient quantity to fill an autoclave chamber, presenting a risk of spillage. Once collected, a manual handling risk is presented in lifting the many bottles of liquid waste into the autoclave. Finally, after sterilisation,
removal of the hot waste from the autoclave provides the same manual handling risk, but now with the operators impeded by cumbersome heatproof personal protective equipment to mitigate the burn risks posed by the now sterile liquid.
The AstellBio Sink is a liquid waste autoclave that removes all these hazards. Laboratory staff can pour liquids directly into the device as soon as they become waste – reducing the timeframe in which waste could be spilled –, and in the quantity that they are produced in – minimising the volume and mass of the load, and thereby decreasing its manual handling risk. Once autoclaved, the liquid waste is despatched automatically to the drain, thereby removing any further stages of manual interaction, and removing the lifting and burn risks.
“The AstellBio Sink provides a simple method of validatable liquid waste sterilisation.” said Astell’s Sales & Marketing Director, Paul Birchmore. “Through its use, a simpler, safer method of liquid waste management can help protect organisations and their staff.” AstellBio will be discussing the AstellBio Sink on Stand Z2.L18 at Medlab Middle East this month.
