The various GMP (good manufacturing practice) guidelines and international ISO standards regarding GMP cleanrooms are complex and often seem contradictory in their guidance, leading to confusion and, at times, misinterpretation. In the case of routine environmental controls, there is little prescriptive guidance and it is up to the cleanroom owner to devise an appropriate control plan. In the generally prescriptive GMP industry, this lack of direct instructions leaves users perplexed.
Reducing costs while developing efficient bioprocesses as fast as possible is a rigorous task. Intensive screenings, including a vast number of different experiments regarding strains, media composition and process conditions, have to be conducted in order to create high yields and product titers.
Tinius Olsen and SDL Atlas participate and work within the Tasks groups at ASTM and the Working Groups at BSI, CEN and ISO meetings on the amendment and development of standards. Seaming properties and tensile strength are the key aspects to be measured in order to assess the fitness and longevity of the final garments.
Wettability is the determining factor in many applications ranging from coatings to enhanced oil recovery and medical implants to pesticides. Due to a wide range of applications, the measurement of wettability, i.e., the contact angle measurement can be done with several different methods.
We started the series of different contact angles with a static contact angle. The static contact angle offers a fast way of characterizing the wettability of the solid. The static contact angle can, however, be problematic as there is no one static contact angle for any real surfaces. In a typical experiment, you measure the static contact angle on several different spots on the same
Being one of the key components in cleaning products, surfactants are in the limelight when it comes to enhancing the performance of a cleaning formulation. Contributing with key properties such as foaming, wetting of the surface to be cleaned, emulsifying the soils and keeping the dirt dispersed in solution to prevent re-deposition on surface, there are several performance
