Cropico has the measure of industrial temperature testing

Precision temperature measurement in industrial applications is provided by a range of high-accuracy digital temperature indicators now available from Cropico.

Temperature affects many processes involved during industrial manufacturing and production stages, so the accurate calibration of sensors is critical to quality control. This can be provided using the Cropico 3000 range which utilises platinum resistance thermometer technology to achieve greater accuracy. For further information and download information, view the company's website: http://www.cropico.com/products/Digital_Thermocouple_and_PRT_thermometer.asp

Platinum resistance thermometers provide a stable temperature coefficient and being a noble metal are not susceptible to contamination. Pt100 (PRT) is the most commonly used and has a temperature coefficient of 0.00385 (European standard) which corresponds to an average resistance change, over the temperature range 0 to 100°C of 0.385Ω per degree Celsius.

The 3000 series offers a choice of inputs for platinum resistance thermometers and all popular thermocouple types.

The 3000 model has inputs for Pt25 and Pt100 platinum resistance thermometers and thermocouple. The 3001 offers the same flexibility as the 3000 but does not include the PT25 input option. The 3002 is designed for use with Pt 100 platinum resistance thermometers only.

Dual channel input allows the comparison and cross calibration of probes and sensor types and a variety of linearisation standards can be selected including user coefficients.

Special features include the ability to eliminate thermal EMF and self heating errors along with the provision to store the calibration data of up to 20 PRT probes.

An internal data memory facility can store up to 4,000 temperature readings for display or direct transmission to a PC or printer. Statistical analysis of stored data can also be undertaken to provide mean, max, min, peak and standard deviation information.

Fully portable with built-in rechargeable batteries providing some 14hr operating time and enclosed in a rugged aluminium case, the 3000 temperature measurement instrument has an accuracy of 0.01°C and resolution of 0.001°C, with SPRT (ITS-90) conversion as standard.

The unit can also be supplied with an optional 19" rack mounting kit to allow the unit to be fitted into any standard enclosure for full system integration. To help with this the unit has options of RS232 or IEEE for communications.

An optional scanner can also expand the instrument to have up to 10 input channels for multi point temperature measurements. The scanner option allows the user to mix different types of scanner cards, to give the 10 input channels. The user can have 4 PT inputs and 4 TC inputs, with the capability to incorporate all common thermocouples from B through to T.

Cropico precision temperature indicators are able to measure with both Pt100 and Pt25 PRT sensors and form part of a comprehensive range of precision measurement instruments available from Cropico Ltd, part of the Seaward Group.

Versatile syringe pump offers extremely smooth flow rate

Dolomite, the world leader in microfluidic design and manufacture, recently launched the Mitos Syringe Pump Extra Smooth (XS), a versatile pumping solution making complex and powerful microfluidic technologies possible. This innovative new pump system has been built on the success of the original Mitos Syringe Pump, but now incorporates a virtually pulse free flow rate.

Designed for applications such as droplet generation, reagent dispensing, cell manipulation, microreactions and any application where precise control over fluid flow is required, the Mitos Syringe Pump XS removes pulsation through advanced drive electronics to provide an exceptionally smooth flow.

With the ability to programme two six-port valves and two syringes to operate in a number of different configurations, a broad range of fluid delivery capabilities are possible. Furthermore, the unit can be controlled directly via the intuitive user interface or the PC software. Fluid can be dispensed either by volume or flow rate over a definable period of time with the ability to create unique flow profiles. With an extremely small footprint (260 x 160 x 250 mm), the Mitos Syringe Pump XS addresses the requirement for a smooth-flow microfluidic system without occupying valuable laboratory space.

New Single quadrupole GC-MS with removable ion source

The new Thermo Scientific ISQ single quadrupole gas chromatography-mass spectrometry (GC-MS) system has a unique, non-venting full-source removal capability. Featuring the new ExtractaBrite ion source, the ISQ system offers simplified operation and maximum uptime for uninterrupted productivity across routine GC-MS applications including forensics, toxicology, food safety and environmental.

The ISQ GC-MS is a highly robust and rugged system that provides high-throughput sample analyses and 24/7 operation. The new ExtractaBrite removable ion source is designed to provide maximum uptime and productivity by extending the length of time between required source maintenance. When the system requires maintenance, the time-consuming and labor intensive procedures including breaking the vacuum, cooling off, cleaning, reassembling and restoring associated with conventional systems are eliminated. The entire ion source can be removed without venting the analyzer. The new ISQ single quadrupole GC-MS also offers an extended mass range, from 1.2 to 1100 u, for analyses across a varied range of compounds.

Thermo Scientific's ISQ single quadrupole gas chromatography  mass spectrometry (GC-MS) system has a unique, non-venting full-source removal capability, and features the new ExtractaBrite ion sourcey, 

The ISQ system is ideally-suited for today's fast-paced gas chromatography methods. Advanced electronics allow the ISQ to acquire and write data to disc at accelerated rates for truly high-speed acquisition in real-world applications. The sequential full scan/selected ion monitoring (SIM) capability provides qualitative and quantitative analyses in a single injection, for confirmation and screening in the same analytical run.

With the ISQ GC-MS, labs are able to operate continuously and productivity can be considerably improved. The innovative ISQ GC-MS represents the most advanced technology available today while providing the opportunity for future upgrades and options. The ISQ mass spectrometer is offered with either the Thermo Scientific FOCUS GC for routine GC-MS or with the full-featured TRACE GC Ultra for improved flexibility and performance.
