16 Lean laser for exact measuring into the nano range


Fritsch’s A-22 NeXT laser particle analysers stand out for their user-friendly, compact, and low-maintenance design. They deliver fast, precise results in the nano- and micro-scale - often in under a minute. A new dry dispersion unit expands the modular system.


The A-22 NeXT Nano measures particles from 0.01 to 3,800 μm with high accuracy even for the smallest particles, while the A-22 NeXT Micro covers 0.5 to 1500 μm for general applications. Both models use a single laser; the Nano requires no extra light source for backscattering. High-resolution sensors capture scattered light signals from all detectors simultaneously, and the angled arrangement of the measuring cell to the laser beam, a signifi cantly larger scattering angle range can be recorded than with comparable instruments. One image covers the full range, speeding up the process - including cleaning - to under a minute.


Using Fritsch’s reverse Fourier design, which is now standard in the industry, the system requires no extra optics and includes few components and virtually no moving parts, making it compact, easy to clean and mostly maintenance-free. The included software comes with predefi ned SOPs for common tasks, which users can modify or replace. SOPs automate key settings, ensuring consistent, reproducible results.


The A-22 NeXT was developed according to a modular concept. For example, customers can choose between a dry and a wet dispersion unit depending on the individual task. In the wet dispersion system, a powerful centrifugal pump with adjustable speed ensures stable measurement. The pump also transports heavy particles and allows the sample material to be distributed quickly and uniformly throughout the entire circuit. A dry dispersion option has recently been added for materials that react in water or other liquids. This can also be used for larger sample quantities in the range from approx. 1 cm³ to greater than 300 cm³. In dry measurement, the sample material is transported from the vibratory feeder via the suction funnel of the dry measuring cell, where it falls directly into a Venturi nozzle operated with adjustable compressed air. Agglomerates are broken down as they pass through the nozzle. The particle size distribution is then measured directly in the laser beam.

Titan Enterprises shares practical insights to help engineers and operators tackle the complexities of precision liquid batching for accurate, repeatable results and effi cient process control. At fi rst glance, metering batches of liquid might appear simple - install a fl owmeter, connect a control instrument, wire in a valve, enter the volume, and dispense. Yet in real-world applications, a host of factors can affect precision and repeatability, making liquid batching far more demanding than it seems.


Modern processing systems require highly accurate fl ow measurement, whether adding water to food mixers, dispensing fl avourings to beverages, or handling aggressive chemicals. Even small inconsistencies in system design can lead to costly inaccuracies and process disruption.


For batching applications, repeatability is key - ensuring the correct volume is dispensed every time. Maintaining stable process conditions helps, but it’s not always possible. Temperature fl uctuations can alter viscosity and volumetric fl ow, while changing feed tank levels can affect dispensing rates. To address this, batching systems should be designed to minimise as many variables as possible within a reasonable budget, selecting fl ow meters, pumps, and valves that can handle any necessary adjustments.


Titan’s NSF-Approved Beverage Flowmeter is one example of a solution tailored for the drinks market. Known for its reliability and repeatability,


this low-cost device is widely used in applications ranging from beverage production lines to self-pour beer walls in bars and restaurants. Typical batch fl ow measurement applications include juice processing, where precise metering of water, fl avourings, and sweeteners ensures product consistency. In beer dispensing systems, fl owmeters monitor and control pours, preventing waste and maintaining profi tability. In bottling operations, fl ow switches and meters detect fl ow loss and manage critical functions like CO2


control and refrigerant protection.


Key considerations for effective batching systems include maintaining hydraulic stability, avoiding pulsating fl ows, ensuring stable conditions, and selecting appropriately calibrated equipment. The correct placement of fl owmeters, understanding resolution needs, and using fast-acting valves or overrun compensation software further enhance batching precision.


By addressing these factors at the design stage and selecting fi t-for-purpose metering technology, engineers can optimise process performance and achieve dependable, high-accuracy liquid batching. More information online: ilmt.co/PL/mnvm and ilmt.co/PL/BNAR


64469pr@reply-direct.com Choosing the right autoclave for your lab


Selecting the right autoclave for your lab is a major decision. If built well, an autoclave can last beyond the foreseeable future. Designed for laboratories that require robust, reliable and high-effi ciency steam sterilisation repeatedly, Priorclave’s autoclaves have a well-earned reputation for quality. The forward-thinking modular design of their autoclaves ensures that it can be upgraded to remain current, which is a valuable consideration.


Priorclave’s Base range covers, as one might expect, ‘the basics’: media preparation, waste loads, and sterilising loose instruments, open containers and labware.


Their Smart range is intended for industrial, research and production labs; suitable for facilities that have more diverse needs. This range of autoclaves can handle all standard tasks (e.g., media prep, waste loads, labware) but also produce drier loads and more reliably handle complex loads that tend to trap air.


The Performance range is designed for high throughput operation (more than four complete cycles every day) and is especially capable of dealing with more challenging loads and items. These jacketed autoclaves are quick to heat and cool rapidly, enabling them to produce drier loads more quickly and reliably, at a lower cost than many comparable sterilisers. This affordable solution enables the most modest lab access to the highest capacity and performance steam autoclaves available.


Whichever range you choose, all of Priorclave’s autoclaves are fi tted with their exclusive Tactrol® start, even whilst gloved.


3 control system, enabling complex programmes to be run with just the press of a single push-button


To further enhance the longevity and performance of your autoclave, every exterior epoxy-coated surface has antimicrobial protection incorporated into it; ensuring surfaces remain cleaner for longer, thereby reducing the risk of microbial growth and cross-contamination.

Salmonella serotyping solution enhances food safety testing


Bio-Rad Laboratories, Inc, a leading provider of life science research and clinical diagnostics solutions, has unveiled the XP-Design Assay Salmonella Serotyping Solution. This innovative tool enables fast and accurate detection and characterisation of Salmonella species in food and environmental samples.


Salmonella is a gram-negative, rod-shaped bacterium responsible for signifi cant foodborne illnesses. According to the US Department of Agriculture (USDA), it is the leading cause of reported foodborne infections in the US, accounting for approximately 1.4 million cases and over 400 deaths each year


Utilising real-time polymerase chain reaction (PCR) technology, Bio-Rad’s assay amplifi es and identifi es specifi c Salmonella serotypes using fl uorescent probes. This molecular serotyping approach facilitates rapid response during outbreaks and supports ongoing monitoring in food processing environments.


The XP-Design Assay provides a streamlined and fl exible solution for serotype identifi cation following initial Salmonella screening. Its ready-to-use format includes serotype-specifi c oligonucleotides (primers and probes), ensuring high specifi city while minimising cross-reactivity, resulting in reliable and reproducible results.


“With the XP-Design Salmonella Serotyping Assays, we are raising the bar for food safety testing by providing rapid and accurate solutions,” said Franck Edouard, Senior Marketing Director of Bio-Rad’s Food Science Division. “This launch reaffi rms our dedication to delivering advanced tools that help detect and identify Salmonella, strengthening food safety measures and consumer protection.” More information online: ilmt.co/PL/6L58
