Gamry Instruments Inc. design and manufacture the Reference™ 600, Reference 3000, Interface 1000 Potentiostats. The choice of potentiostat is usually based on the maximum and/or minimum level of current expected in the experiments. Gamry Potentiostats can function as a potentiostat, a galvanostat, or a Zero Resistance Ammeter (ZRA). All Gamry Potentiostats include (as standard) hardware capable of performing electrochemical impedance spectroscopy (EIS). Gamry Potentiostats electrically fully float, allowing electrochemical experiments with grounded samples such as pressure vessels. Gamry’s eQCM 10M is a rapid, impedance-scanning electrochemical quartz crystal microbalance (EQCM). The EQCM adds a valuable tool in the analytical toolbox of…
Parr supply a family of stirred pressure vessels ranging from 25ml to 5 USG (18.75L). These are split into 7 series which all follow the same design principles and use Parr’s extensive design and manufacture capabilities to ensure that the systems are as user-friendly as possible without compromising the pressure vessel safety. All of these vessels come complete with a stand comprising heater and motor and a Parr 4848 controller. Material of Construction All standard Parr pressure vessels are made from 316 stainless…
Flame Photometry is the technique of choice for the measurement of sodium, potassium and calcium in all sample types for: • mineral extraction• oil industry• paper industry• pharmaceuticals• soil analysis• utilities• food and beverage• chemical manufacture• fertilisers Sherwood Scientific’s Model 410 Industrial Flame Photometer with digital output (for printer or PC connection), also offers sodium linearization capability to allow higher concentrations of Sodium (<40 ppm) to be directly measured using a single point calibration. This facility can be switched on or off according to the operator’s preference or protocol for sodium determinations. The Model 410 also has sodium, potassium and…
Chemisens for Reaction Calorimetry and Process Analysis Reaction calorimeters are tools for analysing chemical processes. The major output from experiments in a reaction calorimeter is the heat production rate, associated with the processes inside the reactor. The heat production curve is then the base for the calculations of a number of important parameters. The technique to measure and the way to calculate the heat production rate is of utmost importance for the reliability of all related calculations and considerations. ChemiSens manufactures ‘True Heat Flow’ reaction calorimeters that are pre-calibrated, which means that each instrument presents the heat production rate directly…
Sherwood Scientific have developed and manufactured a range of two general purpose Fluid Bed Dryers (FBDs): one analogue and one with digital controls of airspeed, temperature and time. In addition, Sherwood Scientific have also developed a programmable FDB where drying programmes can be created and stored on computers. BenefitsThe laboratory fluid bed dryer offers significant advantages over conventional drying techniques: • The high rates of heat and mass transfer ensure much faster and more homogeneous drying than other methods such as oven and vacuum drying.• Drying times range from a few seconds to minutes. Complete drying is usually achieved in…
Latest Applications SciMed Applications Testing the quality of biodiesel What is biodiesel? Biodiesel represents a popular, renewable alternative to traditional petroleum-derived fuels. Its carbon neutral footprint, sustainability and economic viability have brought it sharply into consideration as a substitute and supplement for middle distillate fuels. Biodiesel is synthesised by transesterification of triglycerides into mono-alkylated, fatty esters and glycerine. Why is biodiesel quality control testing important? In the early 2000s, insufficient regulation on biodiesel production led to multiple mechanical issues, such as engine clogging. As biodiesel is less stable than petrodiesel, it is more vulnerable to oxidation. The products of this…
Thanks to its peculiar properties like corrosion, chemical resistance, electrical conductivity and ductility, gold is widely used in electronics industry as material for electrical connections in mass manufactured electronic devices such as circuit boards, integrated chips and semiconductors but also in a variety of novel microelectronic devices like sensors. The well-known biocompatibility of gold has led to its medical use since ancient times. Also a large variety of new applications in high-tech areas, like nanomaterials, are becoming increasingly important. High purity gold (> 99.999 %) is indispensable, since even the smallest contaminants can affect the manufacturing processes as well as the…
