Ensuring Safety of Powdered Infant Formulae
Oxoid has introduced two new culture media for the fast and reliable identification of Cronobacter species (formerly known as Enterobacter sakazakii) from food and environmental samples.
Faster, more precise programmable control!
From the leader in laboratory presses, 15 to 100 ton clamp capacities, inte- gral electrically operated hydraulic power unit, safety shields, heated platens (optional). Send for catalog.
The ongoing development of a new horizontal CEN-ISO standard method for the detection of Cronobacter species by the ISO/TC 34, SC9 Ad hoc group for E. sakazakii, addresses issues such as the scope of the method, reliability of identification criteria and improvements to the media. In anticipation of these future needs, Oxoid has launched Cronobacter Screening Broth (product code CM1121) and Chromogenic Cronobacter Isolation Agar (product code The Oxoid range also includes media that conform to current ISO requirements (ISO/TS 22964: 2006). This ISO method, which incorporates the use of buffered peptone water (CM1049), modified Lauryl Sulphate Tryptose Broth (CM1133 and SR0247) and Enterobacter sakazakii Isolation Agar (CM1134), allows the presumptive identification of Cronobacter spp. in just 72 hours, unlike the previous recommended method which could take up to seven days.
Oxoid Cronobacter media form part of the extensive range of ISO compliant media for food and environmental testing available from Oxoid.

Uniform and Precise Cooling of Cellular Samples
The FTS Bio-Cool® from SP Industries, Inc delivers uniform and precise cooling of cellular samples at a controlled rate to as low as -80°C.
Available only with Fritsch Cutting Mills: all grinding parts can be removed for cleaning in just a few seconds without tools – unbeatable fast, simple and efficient. This makes them ideal, time saving assistants in the comminution of fibrous and tough materials, plastics and heterogeneous mixture of materials and for sample preparation for RoHS and WEEE analysis.
Practical applications include: comminution of toys – to verify lead; comminution of PET-plastic bottles/PET pressings – for analytical assessment of the recycled material for the production of higher value products; comminution of all kinds of nuts – for example to verify the contamination with mycotoxins; comminution of natural rubber – for analytic assessment of the crude materials, before they can be used for further processing; comminution of leather – for chemical analysis and for analytical monitoring; and comminution of wood - for the analysis of matured timber in regards to heavy metals, arsen and PCP/PCB.
The mechanically refrigerated Bio-Cool™ provides a reliable, safe and quiet alternative to controlled-rate freezers that utilise liquid nitrogen as the refrigerant. Unlike liquid nitrogen systems that surround samples with a cold vapour phase, the Bio-Cool immerses samples into a well-circulated, cold liquid bath. The circulating liquid allows more efficient heat transfer to the samples and maintains a more consistent temperature profile at all locations.
Advantages of the Fritsch cutting mills include; especially simple operation for fast work; unmatched ease of cleaning thanks to patented quick opening facility; optimum airflow for particularly fast grinding and secure protection against clogging; more stable running and low wear due to the patented double cone bearing of the rotor; exceptionally long service life through use of replaceable and fixed knives; unique grinding chamber geometry: minimal dead space and progressive cutting geometry between the rotor and the fixed knives – for faster and simpler operation; and grinding parts with different cutting geometries and materials - perfectly adjustable to individual applications. Fritsch Cutting Mills are available in different configurations – for each application the perfect Mill.

With its small footprint, low operating costs and high reliability, the Bio-Cool is an excellent choice for applications including the freezing of murine, bovine or human embryos as well as the cryopreservation of embryonic stem cells.
The Bio-Cool has an easy-to-use programmable microprocessor controller with the ability to program and store up to eight different protocols, each with up to eight distinct segments specifying ramp rate, hold temperature, and hold time. The Bio-Cool 80 model is a registered medical device and is available with data collection capability. Elimination of liquid nitrogen handling and usage, better freezing results, simple straightforward operation, and SP Industries world- class service support all make the Bio-Cool the controlled rate freezer of choice for most clinical, commercial, and research applications.
