Tips For Optimal Pipetting Results
There are several environmental factors to be aware of when pipetting. They can all lead to inconsistencies in your results. Be aware of the temperature and humidity levels in the room. The smaller the difference in temperature between the pipette, tip and liquids, the more accurate the results. Evaporation of the liquid can be eliminated by humid air; dry air can cause sample evaporation.

Interpreting The Results After A Chemical Decontamination Cycle Performed With Vaporized Hydrogen Peroxide
The unexpected growth of a biological indicator (BI) at the end of a decontamination cycle is certainly an undesirable and problematic event. What can and should be done at this point?
The Purpose And Application Of ISO 21501-4
ISO 21501 is titled “Determination of particle size distribution – Single particle light interaction methods” and consists of 4 parts. Part 4: Light scattering airborne particle counter for clean spaces applies to handheld, portable and remote airborne particle counters used in cleanrooms.
TSI® AeroTrak® Remote With Pump Particle Counters Installation Considerations
When specifying particle counters for continuous monitoring applications, such as pharmaceutical aseptic manufacturing processes, there are many system design decisions to be made. These will include instrument location and how to get services such as vacuum and communication cabling to that location, as well as protecting the unit from regular cleaning activities and considering easy access to perform ongoing calibration and maintenance.
Highlights On “Equivalent Time” F0 Sterilization
It has been experimentally shown that the reaction of thermal degradation of micro-organisms obeys the laws of a first order chemical reaction (i.e. like a chemical decomposition reaction) in which the reaction rate is proportional, in each moment, only to the amount of product still to be degraded (or decomposed).
Particle Testing in Cleanroom High-Pressure Gas Lines for ISO 14644
This paper provides guidelines for the testing of high pressure gases used in cleanrooms according to the cleanliness limits derived from the ISO 14644-1 cleanroom classification standard, the FDA cGMP guidelines and the EU GMP Guidelines. Specifically, this applications paper relates to satisfying the air particle concentration limits of Class 100 (ISO 5) where product is exposed to the air environment.
Rouge & Biofilm: Compounding Cleaning Challenges
Rouge may facilitate the development of more tenacious biofilms. Both rouge and biofilm represent cleaning and decontamination challenges to manufacturers. By Michael Gietl and Paul Lopolito
