Choosing the right wipe for your cleanroom

In order for a cleanroom to sustain its appropriate cleanroom classification, employees not only have to follow stringent Standard Operating Procedures (SOPs) but also use the right products that are specifically designed for cleanrooms. Written by Ying Zhang

New strides in H2O2 biodecontamination

Since the emergence of ‘isolator technology’ in the 1980s, hydrogen peroxide has been the favoured agent for biodecontamination because the residues are benign. However, as effective use has been challenging due to a multitude of factors, it is interesting to compare a new ultrasonic dispersal method to the classic flash evaporation one.

Using Computational Fluid Dynamics for challenging designs

Together with the increasing design technification and process optimisation is the need for a more accurate analysis and comprehension of physical phenomena, as well as an analysis of their very complex interactions. During the last few decades CFD has been widely deployed within several fields. Written by Miquel Vidaña

The characteristics of water purity levels and how to verify them

Water is one of the most important variables in a controlled environment for maintaining cleanliness and even the most robustly conceived project can be fatally undermined by a lack of due attention. Mike Seed from Elementar explains

Implications of operator behaviour

Personnel working in cleanrooms, have since the beginning been, and furthermore still are, the most critical elements when it comes to protecting products and processes from contamination. The question is: Can all the newly developed technologies within cleanroom technology reduce, minimise, or even fully eliminate the need of cleanroom operators? Written by Matts Ramstorp

Inconsistent findings: Should HEPA filters be used for coronavirus?

Together with the COVID-19 pandemic, the complexity of the previously presented inconsistencies due to various reasons, leaves its place in the current rewriting of the science of microbial flow and aerosol by air. Metisafe's Serdar Tuncer explains

Medicinal quality risk management: A holistic view

Contamination control is a continuous process in which data trends, product information and new regulatory requirements should be evaluated on an ongoing basis. Patrick Nieuwenhuizen from PharmaLex delves into the microbiological perspective

EN 17141: Putting it into context

The new European standard outlines the importance of understanding the risks of microbial contamination. Being able to accurately identify microbes isolated from the controlled environment is vital to assess risk to pharmaceutical products, and ultimately patients, and ensure that these organisms can be eliminated or controlled. Duncan Barlow from Charles River lays out the most important parts

Identification methods for bacterial isolates

Identification of bacterial isolates provides vital information for companies undertaking environmental monitoring programmes, but methods vary greatly. Vikki Warren from NCIMB discusses

Partnering with suppliers to get the best out of your Contamination Control Strategy

The process of developing a CCS looks complicated on paper, but the practicalities of implementation can be even more so. To close all the gaps between practices and requirements requires a special touch

Disposable contamination control clothing

In the majority of cases cleanroom clothing is manufactured from re-usable cleanroom fabrics which can be processed, decontaminated and worn many times. In some applications however it is appropriate to consider disposable clothing items, which although generally low comfort and high cost, are available in a wide range of options and are simply disposed of after use

Interview with Jessica Rayser | Charles River Laboratories

Microbial monitoring is key to a well functioning cleanroom. Project Manager for Charles River's Accugenix services, Jessica Rayser, goes into depth about sustainability in EM procedures, the pandemic, and the future of rapid microbial methods

UMBC deploys BioFlash for airborne detection of SARS-CoV-2

Singapore scientists develop antibacterial bandage from durian husk

The team of four NTU researchers took two years to research and publish their findings and is now looking for industry partners who may be keen to take their antibacterial gel bandage to market

Assessing disinfection rotation at the point of use: Designing a field trial

Qualifications required for disinfectants consist of three phases: suspension tests, surface tests and field trials. The first two phases are well-described as either European or US standards, with surface testing against a range of representative surfaces being regarded as providing a more robust challenge than the suspension test. What is not described in any standard is the field trial. Written by Tim Sandle
