Flame Photometer

The model 360 Flame Photometer responds to the current demand that five filters come standard in a low-cost instrument. This instrument brings unrivalled precision, ergonomic design, and ease of maintenance to industrial flame photometers. The photometer is fundamentally more stable, less noisy, and has lower limits of detection than would be expected in such a cost-effective instrument. Ease of operation is ensured by the ergonomic design, which uniquely places all the controls, the pressure gauge, air regulator, and sample introduction on the front of the instrument. The large unobstructed sample work area features an innovative spill containment tray which is easy to remove and clean. LEDs on the front panel indicate the filter selected—sodium, potassium, lithium, calcium, or barium—and the flame status. Applications include the analysis of sodium in food, drinking water, waste water, and cement manufacture. The 360 is also an ideal choice for the education sector. The instrument has a conveniently small footprint of 20 x 30 cm and provides exceptional ease-of-maintenance.

Amine coupling

HOOK NHS-dPEG4-Biotin couples to proteins and peptides through its N-hydroxysuccinimide (NHS) ester, and the long polyethylene glycol (PEG) spacer arm imparts water solubility, reducing aggregation. The product is available in two sizes. The larger format is designed for the coupling of 1–10 mg of protein per reaction and is suitable for 10 couplings. The micro kit is supplied with the single use OneQuant HOOK NHS-dPEG4-Biotin and is designed for the coupling of 50–250 μg of protein per reaction and is suitable for 8–10 reactions. Each kit is supplied with a specific Optimizer Buffer for greater coupling efficiency and SpinOUT columns for the removal of uncoupled biotin. The large format has a HABA-Biotin assay to quantitate coupling efficiency.

Recirculating Chillers

Designed as a modular platform, the ThermoFlex Series of Recirculating Chillers offers a wide variety of options and cooling capacities that can be configured for diverse applications in markets such as aerospace, industrial, laser, medical, printing, and semiconductor processing. The latest addition, the ThermoFlex 24000, has a cooling capacity of 24,000 watts to meet the needs of researchers who require a high level of cooling performance. The ThermoFlex chiller platform was developed to be an easy-to-use low maintenance, high performance chiller platform configurable to the most demanding applications. Each chiller includes water filters that can be changed while the unit is in operation and an intuitive user interface for ease-of-operation. End-users benefit from a quick start guide for seamless start up in minutes.

Syringe pump

The Mitos P-Pump provides a pulseless liquid flow, using a precise pressure driven pumping mechanism. With excellent response time and accuracy, this pressure driven flow is ideal for microfluidic systems where a highly stable flow is required. This includes applications such as compartmentalized chemistry and alginate polymerization, which necessitate the stable formation of oil-in-water or water-in-oil droplets; however their monodispersity (size consistency) is key to obtaining accurate and repeatable results. The Mitos P-Pump provides a coefficient of variation in the droplet diameter of less than 0.6 percent. Its precise pressure-driven pumping mechanism delivers liquid with a smooth and even flow, whereas even the best motor drives and mechanics of a syringe pump have slight nonlinearities, which cause unwanted pulsation.

3D Image Analysis

The universal 3D image analysis Volocity software is designed to give research institutions working with confocal microscopes a deeper understanding of cellular biology. Analyzing images in 3D delivers more accurate measurements and the quantitative data to advance scientific breakthroughs in cellular sciences, including cancer and stem cell research and neurological and infectious diseases. The Volocity software platform is a portfolio of high performance 3D image analysis products for the visualization and measurement of cells. The new Volocity Demo is a fully functional analysis version of the software that allows researchers to take their own microscope image data, and explore and evaluate Volocity's analysis capabilities on their own time without time limitations. This free downloadable version allows scientists to measure and analyze the crucial relationships between tissues, cells, and their organelles; generate quantitative data; and create 3D images and movies, which they can then go on to publish with a full Volocity license.
