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

How To Eliminate Heat Effect In Your Fume Hoods
Chemical procedures commonly require the introduction of heat. This is typically in the form of a hot plate or open flame. While the best place to perform these types of chemical procedures is inside a chemical fume hood, most people are unaware of heat’s effect on the airflow through the fume hood, and the potential impact on containment.

Water Purity And Lab Glassware Washers: Just How "Pure" Does It Have To Be?
Water purity supplied to a laboratory glassware washer for rinsing has been the subject of debate in regards to the end result of producing clean glassware. It should be noted that the term ‘deionized water’ does not reference any specific water purity level. The deionization of water produces water within a wide range of purity levels. The deionization process can be used to make medium grade water at 10-20 microsiemens of conductivity, or, it can be used in polishing systems to produce water with a 16-18 megohm resistivity level.
