New Products Spectrophotometer measures wavelength range in three seconds The Jenway 7200 Series Diode Array Scanning Spectrophotometers from Cole Parmer have been designed for fast and easy use in life science applications. This spectrophotometer was constructed for use in the fields of molecular biology laboratories, biotechnology, biochemistry and cell biology applications due to its compact and lightweight design. The product uses electrical scanning to measure wavelength range using diode array technology simultaneously in under three seconds. The reduction of wait times increases the potential of productivity in the labs. Additionally, each dataset contains readings from the complete spectrum, making the data readily available for future analysis. The detector’s orientation shields the array from stray light, allowing an individual to perform measurements with the lid open, quickly exchange samples, and decreases user errors in results. The spectrophotometer has a small footprint, taking up limited space with a large colour touch screen interface for an easy setup and simple operation in the lab. The USB port on the rear can connect to a printer, while the USB on the front allows for flash drives to store data, quantitation curve uploads, and firmware updates. It is compatible with a range of small volume cuvettes, making it an excellent tool for measuring the purity and concentration of DNA, RNA and other biological samples. The instrument has also been preprogrammed with methods for the quantification of nucleic acids and proteins, measuring optical density of bacterial cell cultures such as E. coli and yeast cells, and enables scientists to measure cell growth before harvesting.

Ductless workstation features variable speed control Hemco Corp. has released a ductless hood workstation that is equipped with an activated carbon filtration system that is ideal for fumes, odours, non-hazardous chemical vapours and particulate filtration. It is completely self-contained with an integral recessed work surface to contain spills. The clear hood surrounds the instrument to provide a platform for clear viewing on three sides, as well as providing a layer of safety between the research and the researcher. The sash can also be modified for use with a microscope if required. There is a variable speed fan that provides a high to low level of air flow for use during sensitive operations. It conforms to UL, CSA, & CE requirements, and operates on 115V AC / 60Hz, or 230V AC / 50Hz Internationally. There are electrical port exits on both sides. Filters are easy to change and need to be done roughly every sixty to ninety days, depending on usage. Typical applications include sample weighing, general chemistry involving small volumes of common chemicals, individual workstations, tissue staining and processing, education and containment of forensic applications.

EVOS FL Auto 2 imaging system The Invitrogen EVOS FL Auto 2 Imaging System has been designed to bring a high-level of performance with more advanced capabilities and to simplify demanding cell-based imaging applications, including livecell imaging, image tiling, and z-stacking. The new instrument can scan a 96 well plate in three fluorescent channels in less than five minutes making it a quick and efficient model. The imaging system can be customized to meet a variety of needs with over 20 user-friendly LED light cubes, dual monochromatic and colour cameras, sports a variety of objectives ranging from 1.25x to 100x, and has multiple vessel holders. The time-lapse live-cell imaging options allows for precise control of temperature, humidity and gases for normoxic, or hypoxic conditions, and the area view of the imaging system moves rapidly from low to high magnification to easily define and capture the area of interest. These time-saving features such as autofocus, rapid stage movement, and automated routines reduce time spent on experiments while still acquiring high-quality data.

New gasket and braided hose range from BioPure The Watson-Marlow Fluid Technology Group (WMFTG) has added additions to the BioPure range. BioPure has innovated a range of high purity platinum-cured silicone gaskets and platinumcured silicone braid hoses to add to the current collection of fluid path components. The gaskets and hoses have been designed to meet the exacting requirements of biotechnology and pharmaceutical single-use applications with the highest level of validation available and extractable data in line with BioPhorum Operations Group (BPOG) guidelines to enable users to simplify and expedite validation procedures.The silicone, platinum-cured gaskets have been designed for bioprocessing applications where fluid paths are required. Each gasket has been engineered to achieve a smooth bore, contaminationfree fluid path under clamping compression. They are designed in accordance to standards of the ASME-BPE and are ISO14644 Class 7 cleanroom manufactured and packed. The gaskets are available in ten varied sizes, ranging from ½” to 8” unflanged, and in eight flanged size options from 1” to 8”. The silicone platinum-cured braided hose offers another biotech and pharmaceutical fluid path option. These single and double-braided flexible hoses have been designed for high pressure situations. The hoses offer an immense bending radius and the continuously extruded silicone bore assures the validity of the contacting fluid. They are also built to withstand repeated autoclave and sterilisation processes. BioPure platinum-cured silicone braided hoses are manufactured and packed within an ISO14644 Class 7 cleanroom environment to thereby give users full batch traceability to raw material. There are ten inner diameter sizes for single braided hose are available from 0.125” to 1”, while double braided hoses come in ½”, ¾” and 1” internal diameters. BioPure’s silicone hose is similarly supported, as is the gasket, by the highest level of validation and extractable data.
