Heating And Cooling A Laboratory: Important Considerations For Equipment And Design
ASHRAE Standard 55-2004 determines the temperature, humidity and airflow which the average worker is comfortable; and though people in many industries have the luxury of dressing for the seasons, laboratory workers are usually burdened with an extra layer or two of protective garb. So, room atmosphere considerations also need to take into account that many laboratories have their own requirements as to temperature, humidity and airflow (ventilation). All of this adds up to a laboratory having very strict conditions of the facility’s internal air quality. By Brian Garrett, LEED Green Associate, Product Specialist, Labconco Corporation
WHITE PAPERS & CASE STUDIES
Air Particle Counters Resistant To Vapor Hydrogen Peroxide (VHP)
The use of Vaporous Hydrogen Peroxide (VHP) is commonplace in the pharmaceutical industry for disinfecting sterile manufacturing cores. Since VHP is a strong oxidizing agent it can be damaging to certain internal components in optically based air particle counting instruments. The MET ONE series of air particle counters have been specifically designed to utilize materials that will not be damaged by exposure to VHP. The testing outlined in this paper demonstrates the resistance of these components and stability of the instrument over an extended period of exposure time.
Major Nutritional Supplement Manufacturer Increases Production With New Mixing And Blending System
A major nutritional supplement manufacturer needed to address the need for greater efficacy and additional capacity in the production of various products. Custom Powder Systems manufactured a 5000 Liter blender that fits and can be loaded and discharged within their limited manufacturing space and low ceiling heights.
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.
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.
