E.Coli Testing Protocols Seward Ltd, manufacturer and developer of the world leading, patented Stomacher®
successful year for sales of its Stomacher® Paddle Blender range, announces a highly 3500 large volume sample preparation systems. This follows recent changes to USDA
Escherichia coli 0157:H7 testing protocols, where an expanded description of how its Food Safety & Inspection Service (FSIS) confirms and reports on this virulent food pathogen was published.
All meat products consumed (whether locally produced or exported) within the US must have undergone the recently renewed FSIS
E.coli 0157:H7 testing protocols. Within these, the volume of sample and diluents has been increased to 125g of food sample in 1.25L broth to maximise the opportunity for pathogen detection. Detailed within the revised Laboratory Guidebook chapter on ‘Detection, Isolation and Identification of Escherichia coli O157:H7 from Meat Products’, a Stomacher 3500 is used for the sample preparation of varying quantities and types of meat sample.
The Stomacher 3500 range, including Stomacher bags, is available specifically for large volume (400ml to 3.5L) blending and extraction, where all the washing solution or solvent is required to be retained for microbiological analysis.
The Stomacher 3500 is unrivalled in the market of large volume sample blending and extraction, making it ideal for routine sample preparation of a variety of products for microbiological testing,” said Stuart Ray, Technical Director, Seward. “This is due to its quality, robust components which make it extremely durable, even when processing the largest and toughest of samples. In fact we have examples of these large systems still going strong after 20 years of hard service in many industrial settings.”

SmartBuffers and SmartReagents are among the Medicago products now distributed in the UK exclusively by Cambio. Founded in Uppsala, Sweden, Medicago AB specialises in the design, development and manufacture of high quality research bio-reagents as well as diagnostic and biochemical kits. Cambio also offers Medicago Absolute Lectins, Immuno Reagents and Bioactive Proteins.
Flow Chemistry Systems Green, Fast and Clean
Accendo Corporation's automated chemical flow reaction systems utilise a segmented flow technology that enables automated reaction preparation, synthesis and online analysis.
Drug discovery and process research scientists have adopted Accendo's technology to expand their chemistry capabilities and dramatically increase laboratory productivity. These systems have enabled the pursuit of faster, greener and cleaner reactions.
The Accendo systems accelerate users chemistry and even reactions under extreme conditions like highly aggressive reagents, forbidden chemistry or extremely exothermic reactions can be performed.
The selectable reactor conditions are -20°C – 300°C and up to 150 bar and these conditions allow the use of greener solvents such as methanol, ethanol or propanol.
The systems automate reaction preparation and injections, and scale up from milligrams to hundreds of grams with integrated automated online LC/MS analysis.

Preparation of biological buffers in research and clinical laboratories is often perceived as tedious and error-prone. Manufactured in a controlled clean environment using highly purified, analytical-grade chemicals, Medicago’s SmartBuffers are supplied as precisely pre-weighed tablets or powder pouches with given concentration and pre-set pH. Preparation is as simple as dissolving one tablet or the contents of one pouch in the specified volume of deionized water, saving time and eliminating errors in calculation, formulation and weighing.
These products are very much easier to store than litres of made-up buffer, while a long shelf life of at least three years is another significant advantage.
Medicago SmartReagents are also available as pre-weighed tablets or powders with the highest quality and purity, making them ideal for standardising laboratory work. Ready to use in minutes, this range of reagents and biochemicals are suitable for numerous life science and biotechnology applications.

Labmate-online.com Portable Calibration Unit Provides Mobile Calibration Standard
Providing an efficient and affordable secondary calibration standard, the Portable Calibration Unit (PCU) from Alicat Scientific integrates three Alicat Laminar Mass Flow Meters into a portable industrial briefcase that can be taken anywhere. The PCU is ideal for use in laboratories, industrial plants, process facilities and by field technicians to verify proper operation of flow meters and flow controllers from any manufacturer.
Unlike other currently available secondary standards, the PCU is fully self-contained and does not require any additional support equipment or line power. It is as simple as having a tech arrive on site, plug the unit into the system and take readings. The PCU also has on-board digital output to send flow data to a laptop or other computer system via multi-drop RS-232 communications for simultaneous data acquisition.
Each of the integrated meters on the PCU displays mass flow, volumetric flow, pressure & temperature with high accuracy calibration of +/- (0.4% of reading + .2% of full scale). The ranges of the flow meters are specified by the end user upon ordering the PCU. Twenty pre-set selectable gas calibrations and ten pre-set gas mix calibrations (specific gas mixes and calibrations) are available.
Alternate and adjustable standard temperature and pressure simplifies comparisons to other flow devices. The unit has an integrated totaliser for tests that require long term averaging. Alicat’s FlowVisionSC GUI software is included, enabling graphing, data acquisition, and scripted polling.
The PCU can be plugged into wall power or powered by two standard 9V batteries. The unit will alert the user via a bright LED indicator to replace the batteries when power falls below a minimum threshold. Like Alicat's standard line of flow devices, the PCU has no large mechanical parts to service or fail. All of Alicat’s products carry the CE marking and are NIST traceable
