Laboratory Products 35 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.

Next Generation Hotplate and Stirrer Announced
Wiggens’ innovative technology has been used to produce the new generation round top hotplate-stirrer WH240 series. The hot plate uses unique infrared technology with a power of up to 600W and the ceramic glass has a high infrared transparency which results in a very high heating efficiency in a standard round top plate of 135mm diameter. Optimised PID parameters allows many different kinds of applications. A specially designed stainless steel protection ring, sealed outer shell of the top plate, and the robust ceramic glass can resist a thermal shock of 700ºC guaranteeing an enhanced longevity of the instrument. The control system has been updated to a higher level using a bright LCD display with adjustable backlight for user friendly monitoring and setup. Adjustable safety temperature setting using independent safety temperature circuit ensures a high safety level. A well-chosen design with reliable embedded temperature sensors inside the ceramic glass top plate makes the control more stable and accurate. A wide range of accessories suitable for the standard top size can provide uniform heating for multiple size vials in parallel reactions with a superior stirring effect as well. The products are now available for the international market with various voltage standards.
41468pr@reply-direct.com ADVERTORIAL Integra Highlights Benefits of Low Retention Pipette Tips
Integra has released an application guide highlighting the importance of choosing the right disposable tips for the liquid you’re pipetting. The recently published Performance of Low Retention GripTips from INTEGRA demonstrates how these high quality consumables can improve pipetting performance for viscous and low surface tension liquids.
High quality pipettes and correct techniques are essential to ensure reliable and reproducible results, but the physiochemical properties of the liquid can also have a significant impact on accuracy and precision, particularly at low volumes. Polypropylene (PP) is the material of choice for most disposable pipette tips, as it repels aqueous liquids, leading to low fluid retention within the tip. However, liquids with a low surface tension – such as oils or solutions containing detergents – or the viscous fluids common in some biological applications can adhere to the inner surface of PP tips. This ‘wetting’ prevents efficient

liquid ejection during dispensing, affecting reproducibility and leading to wastage of precious samples or reagents. Integra’s Low Retention GripTips – designed to work in combination with the company’s range of manual and electronic pipettes – offer an ideal solution to overcome this issue, ensuring optimal liquid recovery and improving experimental results.
