Laboratory Products 39 Advanced viscometers for QC and R&D labs


Wiggens is proud to announce the expansion of its viscosity measurement equipment offerings, essential for rapid and accurate readings in QC and R&D laboratories. The updated range now includes rotational viscometers, capillary viscometers, automatic viscosity measurement systems, and falling ball viscometers.


Introducing the Premium Plus line of rotational viscometers, designed to determine viscosity and other rheological properties of homogeneous samples with precision. This modern series combines sleek design with cutting-edge electronic technology, positioning Wiggens at the forefront of viscosity measurement tools.


The Premium Plus series features significant enhancements, such as a touch keyboard for user-friendly operation and new software that improves sample analysis accuracy. The equipment also offers advanced options such as flow curve visualisation and modes including step, multistep, and ramp, providing substantial benefits to users. A notable innovation is the continuous reading feature for advanced products, complemented by a USB connection for easy data download to any computer.


Capillary viscometers operate on the principle of measuring the relationship between viscosity and time, using gravity as the driving force to determine kinematic viscosity. With the known density, dynamic viscosity is easily calculated.


The automatic viscosity measurement system improves data accuracy, reduces operator errors, and minimises exposure to chemicals, making it ideal for measuring the relative viscosity of polymers and the absolute viscosity of oils.


The Wiggens falling ball viscometer, Visco Ball, complies with DIN 53015 / ISO 12058 standards, providing precise measurements of transparent Newtonian liquids and gases. Using six special glass or metal balls, the device times the rolling and sliding movements through the sample liquid in an inclined cylindrical tube. The viscosity is determined by the time taken for a ball to traverse a set distance, with additional measurements possible by inverting the tube and applying the return constant. Results are given in dynamic viscosity units (mPa·s), making it suitable for industries such as paint and coating.


These advanced viscometers from Wiggens deliver high-performance solutions for viscosity measurement, ensuring accuracy and efficiency in laboratory settings. More information online: ilmt.co/PL/Q6xm

Pioneering products for sustainable food development


AMSBIO offers a range of kits, media, and reagents that facilitate the development of food in an environmentally sustainable manner, ensuring minimal resource wastage and no adverse impact on consumer health.


Recent biotechnological advancements have led to the creation of cultured meat - meat grown in a laboratory using stem cell technology. This innovation mimics the texture, flavour, and nutritional value of conventional meat. Cultured meat has the potential to be less resource-intensive, reducing the need for animal husbandry and slaughter, which in turn can decrease air pollution, deforestation, water use and contamination, biodiversity loss, antibiotic resistance, and foodborne illnesses.


AMSBIO’s products for cultured meat research and development fall into three main categories. First, they provide the right environment and stimuli for cultured cells. Second, they offer standards and kits to test if these cells behave like their in vivo counterparts. Finally, they supply cryopreservation media to archive cells for reference or future use. Their range includes skeletal muscle differentiation kits, recombinant extracellular matrices, 3D scaffolds, and cryopreservation media.


Cultured meat production requires a suitable source of cells that can differentiate into muscle and fat cells. A 2023 study by Kalkehi et al. highlighted the challenge of repeated cell harvesting from different animal sources. This was overcome by successfully cryopreserving bovine myogenic cells in CELLBANKER®


media from AMSBIO, which maintained cell quality for future production.


Another crucial component in developing new cell-based foods is the culture media and matrix that support cell growth and differentiation. In 2022, Takahashi et al. demonstrated the efficiency of iMatrix-511 Laminin E8 fragments, available from AMSBIO, for the adherence and differentiation of bovine myogenic cells into myotubes. These micropatterned culture substrates formed scaffolds upon which myotubes could align into myofibers, mimicking native muscle tissue structure.


Ongoing research aims to determine the optimal combination of cellular sources, growth media, bioprocesses, and biomaterials to scale up cultured meat production commercially. All materials and procedures used must comply with strict GMP and FDA regulations to ensure consumer safety. The main challenge is the high cost of large-scale production, necessitating standardised procedures and automated processes to reduce costs. AMSBIO aims to ease the transition from bench scale to manufacturing with GMP-compliant products and services.

New WalkLAB HD9031 Dissolved Oxygen meter from Trans Instruments


Trans Instruments (TTBH PTE LTD, Singapore), a leading manufacturer specialising in pH and conductivity instrumentation for over three decades in water analysis, is delighted to introduce the latest addition to our WalkLAB series: the WalkLAB Dissolved Oxygen meter HD9031.


Designed for both laboratory and field use, the meter boasts a dual-display LCD with integrated temperature readings. Encased in a rugged ABS housing, it is fully splash-proof and weather- proof with an IP rating of 65.


The meter is user-friendly, displaying readings in mg/L (ppm) within a range of 0 to 20ppm and offering an accuracy of +/-0.4ppm. It comes equipped with a probe suitable for standard BOD bottle fittings, facilitating Biochemical Oxygen Demand measurements. The air calibration feature, complemented by a countdown function, minimises errors. Additionally, the meter allows for recording sessions to capture maximum and minimum readings during testing.


Automatic atmospheric and salinity compensation settings enhance its versatility, especially in non-sea-level locations or when dealing with samples with higher salinity. This automation streamlines readings, eliminating the need for manual conversions within the test session thus making it an ideal choice for both laboratory and field-testing environments.
