26 New precision balance with alibi memory
KERN & SOHN introduces a new precision balance to the market: The KERN PCJ is tailored for integration with Laboratory Information Systems (LIMS). It features a menu lock function preventing unauthorised access to the device. Within the balance’s integrated alibi memory, weighing data is documented with date, time, and identification number. This enables the proper electronic evaluation and further processing of results for legally required weighings.
Data and control commands exchange between the balance and PC or network can occur through multiple interfaces, such as RS-232, USB, Bluetooth, WIFI, or Ethernet. This is facilitated by the built-in KERN Universal Port, onto which the desired interface adapters can be simply attached.
The internal calibration circuitry is adjustable independently from the power source via battery operation and a knob. This feature ensures high accuracy and portability.
The balance’s menu offers several customisable settings. For instance, users can determine button tones, assign a button with different functions for quicker access, and adjust the print protocol as needed.
With the PCJ, KERN introduces another balance featuring a standardised and user-friendly operational philosophy. Balances of this generation
maintain consistency across products in design, menu structure, button functions, interface connection, and interface protocol. More information online:

62488pr@reply-direct.com Precise solutions for low flow liquid measurement
Low-flow measurement is increasingly prevalent across various industries. Yet, as flow rates decrease, the task of controlling and measuring them becomes progressively more challenging. This poses a significant obstacle for users and flow sensor manufacturers alike in their search for cost- effective and reliable flow measuring technologies.
While there isn’t a standardized definition for ‘low flow’ concerning fluidics handling, these applications face distinct challenges compared to larger flows. The minimal volume of liquid involved makes low-flow systems highly sensitive, amplifying concerns about flow stability and performance. Even minor disruptions in process or environmental conditions can significantly affect flow stability in low-flow scenarios.
In the markets where Titan Enterprises operates, low flow rates are considered to be those below 50 ml/min, with many customers seeking flow rates ranging from 2 to 20 ml/min.
Neil Hannay, Senior R&D Engineer at Titan Enterprises, noted: “We are observing a significant rise in the demand for low flow measurement technologies, fuelled by various industries shifting towards transporting highly concentrated liquids that are later diluted at the point of use. This transition results in substantial savings on transportation and storage expenses, while also yielding positive environmental benefits.”
From cleaning fluid additives to beer or soda syrups and flavourings, chemical additives for oil and fuel, paint pigments, or drug administration, the use of low-flow flowmeters is essential. They ensure precise dosing of these concentrated fluids at the end of the process, facilitating accurate dispensing for the correct dilution.
As mentioned, measuring low flow presents a challenging application to address. The energy available in low liquid flow is often inadequate to drive most mechanical flowmeters to provide linear results. Electronic flow meters, on the other hand, may face limitations such as sensitivity, zero drift, and slow response times. This analysis covers five types of flow meter - Ultrasonic, Turbine, Oval Gear, Thermal, and Coriolis - and assesses their suitability for low flow measurement.
Selecting the most appropriate high-precision flow sensor for your application is crucial, as flowmeters can often be the most constraining element of a low flow fluidic system.
Neil stated: “We recognise a robust market demand for low flow meters, and we are presently collaborating with two international OEMs to devise a solution for measuring ultra-low flows leveraging our oval gear technology and miniaturised gears.” More information online:

62331pr@reply-direct.com Chemical resistant diaphragm pumps
The C Series chemical resistant diaphragm pumps from Wiggens are an excellent solution for continuous, oil-free pumping of corrosive gases and vapours and meet demanding applications. The multi-stage construction provides an advantageous combination of high pumping speed and ultimate low vacuum. All major parts in contact with pumped media are made of PTFE which are ideal for extremely aggressive/corrosive gases and vapours. The sealing system provides reduced leakage rates for improved ultimate vacuum (1mbar).
Wiggens is continuously expanding the line of diaphragm pumps and applying new technologies to the C Series. The latest models feature more powerful
motor-driven multi-stage pump heads, making them an excellent choice for applications requiring high vacuum levels with corrosive gases and vapours. These pumps find applications in pilot reactors, industrial rotary evaporators, the semiconductor industry, drying ovens, and various laboratory applications. The maximum pumping speed can reach up to 145L/min.
Equipped with a frequency conversion motor, these powerful pumps can achieve high vacuum levels quickly and with good stability, making them suitable for larger laboratory applications.
Furthermore, the frequency conversion vacuum pump helps reduce noise in the laboratory and extends the service life. If you have any questions about vacuum requirements for your experiments, please contact Wiggens for assistance. More information online:
