Laboratory Products 35 Environmental sample extraction: Overcome limitations of EPA method 3546
Many laboratories using EPA method 3546 for the solvent extraction of environmental samples are aware of the bottleneck of sample throughput plus sample weight limitations.
Traditional extraction of contaminants such as PCBs, semivolatile organic compounds, and PAHs use lengthy methods that also require large volumes of solvents. A recent development - microwave assisted extraction (MAE) overcomes these limitations, resulting in rapid sample preparation with reduced amounts of solvents while working at higher temperatures and pressures.
The Milestone Ethos X microwave extraction system from Analytix can extract organic target compounds from soils in full compliance with EPA 3546 (100-115°C and 50-150 psi). The system is capable of processing up to 24 samples and 30 g of sample per vessel simultaneously thereby improving the limit of quantitation (LOQ) for analysis. This results in the capacity to extract over 200 samples in an 8-hour workday and the potential problems of contamination, memory effects, and cleaning are eliminated due to the use of disposable glass vials.
The handling is very easy, the sample is weighed directly into the vial, hexane/acetone or dichloromethane/acetone (1:1) is added, and the vessel is loaded into the 24 place FastEX that has contactless temperature control in all positions. After 10–20 min of microwave heating, the sample is ready to be fi ltered and analysed by GC or GCMS.
The use of disposable glass vials coupled with speed of extraction and reduced solvent consumption makes the Ethos X a unique and innovative solution for the extraction of contaminants from soils, providing unmatched ease of use and low running costs.

Reliable biosafety and CO₂ incubation for critical labs
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
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.
Avidity Science is the UK distributor and service provider for NuAire, a global leader in high-performance laboratory equipment. The company supplies the full range of NuAire biosafety cabinets and CO₂ incubators.
In laboratory environments where biological safety is critical, the performance and reliability of containment equipment are non-negotiable. NuAire manufactures the highest quality Class 2 biological safety cabinets for the most demanding applications and is universally recognised as one of the world’s leading providers, having designed and built the fi rst modern-day biological safety cabinet. NuAire cabinets are engineered for maximum user and sample protection, featuring dynamic airfl ow control and real-time airfl ow monitoring to ensure containment is always maintained.
NuAire CO₂ incubators provide a precision- controlled, contamination-free environment for sensitive cell cultures. The stainless- steel chamber is easy to clean, while the closed-loop HEPA fi ltration system ensures ISO Class 5 cleanroom conditions by continuously circulating fi ltered air.
Optional O₂ control, RH control, and data monitoring make these incubators ideal for advanced research applications such as hypoxic or stem cell culture.
All UK installations of NuAire equipment are carried out by highly trained Avidity Science engineers, ensuring systems are installed to the highest standard. With a dedicated team of 26 engineers across the UK and over 25 years of experience supporting the life science sector, Avidity Science provides comprehensive servicing, preventative maintenance, and ongoing training throughout the life of each system.
Avidity Science is proud to be a trusted partner, supporting lab performance, compliance, and continuity at every stage.

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.
