Laboratory Products 43 New Webinar Shares How Weighing Accuracy Can Be Protected


Waiting for unstable or drifting measurement readings can be a frustrating waste of time in a busy laboratory. Weighing accuracy can be protected by recognising and eliminating common external influences which have a disruptive effect on weighing, as explained in ‘Worry Free Weighing: Dealing with static and drafts’, an on-demand webinar from the weighing experts.


External factors that can influence weighing accuracy are often overlooked, even though an unreliable weighing result can have a profound effect downstream on the quality of the final result.


An on-demand webinar from Mettler Toledo, ‘Worry-free weighing: Dealing with static and drafts’, features guest presenter Professor Dr Peter Ryser from the Swiss Federal Institute of Technology (EPFL) in Lausanne and provides laboratory personnel with tips and advice on how to reduce or eliminate the effects of disruptive influences on weighing, including electrostatic charges, temperature variations, and air turbulence or drafts. It will also discuss simple steps that can be taken to address these problems, as well as weighing accessories to make the tasks of a balance operator more straightforward and less error-prone.


Two of the latest innovations in weighing technology specifically designed to minimise external influences on analytical and precision balances are discussed during this webinar: StaticDetect™ - automatic static detection for analytical balances; warns whether a weighing result has been influenced by an electrostatic charge and indicates the magnitude of the error; SmartPan™ - innovative weighing pan designed for precision balances; delivers a more accurate weighing result in less than half the time, especially in an unstable environment.


Viewers of this webinar will be able to: learn how to improve weighing accuracy by recognising common external influences; understand how to avoid or control the effect of electrostatic charges on weighing results; realise how to manage temperature differences to maximise the accuracy of weighing; recognise what can be done to eliminate the effect of drafts or air turbulence on the weighing result.

Mass Flow and Pressure Instruments Now Offer EtherCAT Protocol


Alicat Scientific’s line of mass flow, pressure and liquid instruments can now be configured with the EtherCAT protocol. Users of Beckhoff PLCs for industrial automation can now connect Alicat devices with the high-speed and robust EtherCAT protocol.


In the chemical, medical, manufacturing and power industries, Alicat instruments rapidly and precisely monitor and control critical process parameters. The speed and reliability of Alicat devices are particularly well suited to vacuum coating processes, such as Atomic Layer Deposition and Chemical Vapour Deposition. All of the mass flow or pressure controller’s data, including: mass flow, volumetric flow, pressure, temperature, selected gas calibration, setpoint, and totalised flow can be output to a central PLC running a compatible automation protocol. Users may also change setpoint or gas selection, and issue other commands remotely.


EtherCAT joins Alicat’s wide offering of industrial automation protocol options, which also includes Modbus TCP/IP, Modbus-RTU, EtherNet/IP, DeviceNet and PROFIBUS communication options to fit new or existing systems. For easy drop-in replacement of older industrial units, Alicat instruments are made to fit the same space as common industry mass flow controllers. All Alicat instruments are backed by NIST-traceable calibration, comprehensive technical support and a lifetime warranty.

Premium Tensiometer Updated with New Software and Temperature Control Features


Krüss GmbH is introducing an updated version of their successful Force Tensiometer, K100, with their new ADVANCE software, and has also developed two new temperature control units for this measuring instrument. ADVANCE software displays the logical workflow of scientific measurements on an intuitive user interface. The broad scope of methods offered by the K100 include completely automated CMC measurement and processes for characterisation of the wettability of solids and powders right up to the determination of their surface free energy. In parallel with the software release, this measuring instrument also offers technical upgrades, such as a sensor that registers the closing of the sample chamber doors.


ADVANCE controls measurement sequences with the aid of ready-made automation programs, reducing manual steps to the absolute minimum. Measurements can therefore start immediately without any further adjustments. Procedures can also be intuitively modified or even newly created for completely different sequences without any programming knowledge.


The automation programs work hand in hand with the numerous software-controlled K100 components and sensors. For example, closing the measuring chamber can initiate the next sequence step of the measurement without the user needing to confirm continuation. The integrated stirrer can switch itself on and off during the procedure in order to homogenise the sample before measurement. During a critical micelle concentration (CMC) measurement, special Micro Dispensers are integrated in a fully automated procedure which includes creating a concentration series and evaluating the measurement curve.


An additional benefit in the K100 program innovation consists of two powerful temperature control units for different ranges. The Temperature Control Unit – TJ50 exploits the Peltier effect for tensiometric measurements between -15 and 130°C. The unit rapidly reaches the target temperature and keeps it stable due to excellent insulation. The temperature control housing of the unit also encompasses an electromagnetic stirrer, ensuring rapid homogenisation of the sample temperature. Moreover, the TJ50 includes a cooling unit for the Peltier element so that separate counter-cooling is not necessary.


The electrically heated temperature control unit TJ60 quickly and reliably reaches target temperatures of up to 300°C. It enables measurements of the surface tension of polymer melts or bitumen. The supplied disposable sample vessels made of the excellent heat conductor aluminium solve the problem of persistent contamination. Oxidation of the samples can also be avoided by connecting an inert gas.
