44 Ultrasonic Cleaning Solutions for Laboratory Applications
The cavitation phenomenon consists of the formation and growth of millions of microscopic bubbles under a low-pressure stage, produced into the ultrasonic bath due to a high power transducer 40kHz. These bubbles break in all directions and attack every surface in contact with water, erasing dirt, impurities and pollutants when contacting with the materials or pieces into the bath. This phenomenon allows cleaning all kind of items without the need of disassembling, due to all the surfaces being in contact with the liquid. The heating function of the unit allows the acceleration of this cleaning process.
Wiggens presents two series of standard ultrasonic cleaners with reliable quality and useful features, which allows the users a wide range of cleaning applications such as lab materials, medical instruments, dental prosthesis, optics, industrial items, jewelleries, also the degasifi cation or liquid dissolution and compact substances disaggregation.
The following are the standard working volumes supplied: 3, 6, 10 and 22 litres, and bespoke volumes can be ordered for different applications. All functions can be viewed and monitored on a large and clear touch screen display. The parameters can be set by screen touching, including the ultrasonic working power (40% to 100%), bath temperature (20°C to 80°C), timer and warning function for safety.
All models are equipped with lids and trays that allow the parts they introduce to be directly cleaned without damaging the transducers and for easy handling.
In addition to the standard ultrasonic cleaners, Wiggens also offers the ultrasonic cleaners with special added functions. The Shaking Ultrasonic Cleaner is a good example, which means that the sample can be pre-homogenised at a specifi c shaking speed, and then fi nal homogenisation can be achieved in a very short time, using ultrasonic power These two procedures can be carried out simultaneously or separately. Another added function is an ultrasonic cleaner with cooling for use in pathology and analysis labs, where the temperature of bath can be maintained at 10°C to 40°C even with the ultrasonic power generating heat continuously.

Affordable Solution for Partial Sterile Clean Air Areas
For over 25 years, Spetec has been renowned for designing and constructing clean rooms of various sizes, catering to diverse customer requirements. The company has fl exible and innovative approach to creating partial sterile clean air environments.
The core feature of this breakthrough solution is the implementation of a laminar fl ow module, incorporating a high-quality fan and a fi lter system consisting of a pre-fi lter and a high-performance HEPA 14 fi lter. This advanced fi lter is capable of capturing 99.995% of all particles with a diameter ≥ 0.5 µm, ensuring an exceptionally sterile and particle-free zone. The module’s size can be adjusted to suit specifi c applications, allowing fl exible installation either above a workplace in an enclosed clean room or within air-conditioned rooms.
To create larger clean air zones or clean room cells, multiple modules can be installed and interconnected. For environments containing equipment or furniture, Spetec recommends adopting a low-turbulence airfl ow to ensure effi cient air exchange throughout the space. All modules and accessories are manufactured in compliance with GMP standards, with custom sizes available to meet individual customer needs.
The modern modules can be suspended at various heights or securely attached to ceilings, operating discreetly with a fi lter change indicator for ease of maintenance. Depending on the air quality in the room, the fi lter can remain effective for up to four years or more.
This cost-effective alternative to fully enclosed clean rooms proves to be particularly advantageous for new builds and renovation projects. By effectively sealing entrances and windows, a comparable level of air cleanliness can be achieved through the continuous operation of these systems.
Spetec recommends the use of strip curtains to further enhance air cleanliness classifi cation, creating particle-free, sterile work environments. Sensitive equipment and tools can be safely utilised and stored within this space without the need for extensive construction.
In conclusion, Spetec’s fl exible and budget-friendly modules offer a compelling solution for achieving partial sterile clean air areas, eliminating the necessity for costly fully enclosed clean rooms, especially when the freedom of movement within the workspace is essential. With their commitment to quality and innovative design, Spetec continues to drive advancements in clean room technology.

Advancing Mitochondrial Disorder Research Using Electronic Pipettes
Researchers at the Wellcome Centre for Mitochondrial Research (WCMR), based in the Faculty of Medical Sciences at Newcastle University, have adopted Integra Biosciences’ VOYAGER adjustable tip spacing pipette to advance their investigations into mitochondrial diseases. This interdisciplinary research team employs this cutting-edge equipment to optimise multiple phases of their high-throughput screening assays. Their aim is to pinpoint potential drug candidates capable of restoring mitochondrial function, thus enhancing the quality of life for individuals affl icted by mitochondrial conditions.
Adam Creigh, a researcher at the WCMR, explained: “Our team is focused on fi nding treatments by screening large compound libraries, and testing them on patient cell lines with a range of different mutations. Having versatile and reliable equipment like the VOYAGER adjustable tip spacing pipettes is a gamechanger, as we can be focused on testing entirely different compounds from one day to the next. The VOYAGER’s programmable aspiration speeds offer more control than can be achieved manually, meaning that delicate cell lines can be effi ciently handled with care. Setting it to a slow and gentle aspiration ensures that cells are not disturbed during the process, providing a level of precision that is essential. Furthermore, the tip spacing can be changed at the push of a button to accommodate different types of plates and wells, and this fl exibility is invaluable when we are working with various assays and sample formats.”
Adam continued: “The convenience and effi cacy that the VOYAGER brings to our workfl ows is remarkable. It’s in constant demand throughout the center, and the effi ciency of our workfl ows has been enhanced thanks to the reproducibility it offers. It has become an indispensable tool for our mitochondrial disease research and, looking ahead, we hope to get more INTEGRA pipettes to expand our high throughput screening capabilities as part of our mission to fi nd treatments for people affected by mitochondrial dysfunction.”
