TISSUE PROCESSOR Thermo Fisher Scientific Inc. features the new STP 420ES tissue processor for use in high-volume pathology laboratories. The updated instrument features more robust hardware and ease-of-use, enabling the high-throughput processing of large volumes of tissue to meet the demands of today’s laboratories. The Thermo Scientific STP 420ES models are designed to accommodate the most demanding requirements of researchers and pathologists in the field of tissue processing and have become an essential part of the laboratory workflow. The latest STP 420ES has been updated to include more robust hardware to handle the increasing number of samples processed in modern laboratories. The instrument’s dual chambers allow it to perform simultaneous or independent processing of up to 420 tissue cassettes, enabling higher throughput. In addition, ultimate fluid exchange is ensured by the innovative rotational movement of the main chamber. Rotational agitation is also up to seven-times more effective than conventional tidal agitation, eliminating the need for reprocessing.

ARRAYS SABiosciences, a QIAGEN company, launches several new RT2 Profiler PCR Arrays for gene expression profiling in nephrotoxicity, hepatotoxicology, differentiation and embryonic stem cells markers as well as analysis of epigenetic modulators and enzymes. Covering more than 100 pathways, PCR arrays enable scientists to easily and accurately analyze the gene expression in research areas such as cancer, stem cells, biomarker discovery and immunology. The RT2 Profiler PCR Array provides gene expression data from the RNA within three hours and is composed of PCR Array plates, RT2 first strand kit, RT2 SYBR Green Master Mix and the free PCR Array data analysis software. The arrays, originally developed by SABiosciences, make expression profiling accessible for routine use in every lab with a real-time PCR instrument. The experiment is simple to perform and provides sensitive, reproducible, and reliable results to accurately profile multiple genes simultaneously. The RT2 Profiler PCR Arrays as well as all other products from SABiosciences are now directly available from QIAGEN and offer the most comprehensive portfolio for sample and assay technologies for pathway analysis.

BUNSEN BURNER WLD-TEC introduces its Flame 100 Safety Burner, the safe alternative for all traditional Bunsen or alcohol burner applications. The Flame 100 is ideally suited for all flame related applications in the laboratory. The 15 millimeter precision flame allows safe sterilization of microbiological instruments as well as graduated heating of dental tools. Flame size and intensity can be adjusted infinitely. The Flame 100 Burner activates immediately with the push of a button. No match or a pilot flame are required. Optionally, the Flame 100 can also be operated by a foot pedal or an external infrared motion sensor. The Flame 100 is suitable for stationary natural gas and propane/butane gas supplies as well as gas cartridges or gas cylinders. The proven Safety Control System (SCS) is also incorporated in the Flame 100. All potential hazards are constantly monitored and, if necessary, protective measures – such as the shutting off the gas supply – are activated.

CONNECTOR SYSTEM Dolomite introduces the new Mitos In-line Connector System. This innovative connector provides a single, fast and reliable multi-way connection, which offers extensive time savings when compared to traditional connections between individual pipes. In addition to being quick and easy to use, the Mitos In-line Connector provides in-line sealing and highly accurate alignment between the tubes, enabling uninterrupted liquid flow. Available in three standard sizes 4-, 8- and 12-way, the Mitos In-line Connector operates over a wide temperature (-15 0C to 250 0C) and pressure range (up to 10bar), providing excellent chemical compatibility. Furthermore, a low dead volume reduces the risk of cross-contamination between fluid samples, thereby maintaining experimental integrity. The technology benefits a broad range of applications, including chemical and biological analysis, parallel microfluidic processing, providing multi-way fluidic connections between various laboratory equipment. In addition, it is compatible with a variety of polymeric tubes including PTFE, FEP and PEEK. Custom sizes and geometries are also available upon request.

CELL CULTURE InVitria announces the launch of ITSE Animal-Free, a recombinant and defined cell culture media supplement that provides the ingredients essential for high performance cell culture. ITSE Animal-Free provides a solution for maximizing performance in a consistent and animal-free system. Insulin and transferrin supplements are commonly used in cell culture to reduce the amount of serum, such as fetal bovine serum (FBS), required to optimize performance. Until now, researchers used insulin and transferrin supplements that were derived from animal sources. With ITSE-Animal-Free, cell culture scientists have a new alternative that is completely animal-free and well defined because it incorporates recombinant insulin and transferrin.
