What to Look for in a Laboratory Incubator

Written by Bob Sandor

Laboratory incubators used in microbiology laboratories and other research and development applications provide an environment for growing cultures under controlled conditions such as humidity, temperature, and CO2.   Several regulations apply to operating a laboratory incubator so it is important to be certain that the laboratory equipment you buy is designed to meet your particular requirements.

Experts suggest that even before purchasing a laboratory incubator you should first consider what it will be used for and where it will be located.  So instead of buying an incubator and then trying to make it fit your process or needs, turn the procedure around.  This makes sense not only for assuring proper performance; it helps you pick a model that is most cost-effective for your needs.

Window Blind Cleaning with an Ultrasonic Cleaner

Written by Bob Sandor

If you make a living providing commercial or residential window blind cleaning and are looking for a better way to do it, an ultrasonic blind cleaner especially designed for this job provides quick relief.  Quick is the operative word here because ultrasonic energy will remove in minutes smoke stains, dust, grease, finger marks and other soils thanks to the power of ultrasonic cavitation.

Single or multiple blinds of any configuration – Venetian, accordion, insulating, roll up and vertical as examples – are placed in a basket then immersed in the cleaning side of a dual-tank ultrasonic cleaner filled with an ultrasonic cleaning solution. When the unit is activated transducers affixed to the underside of the tank create billions of tiny bubbles in the solution.

A Primer on Drug Stability Testing in Stability Chambers

Written by Rachel Kohn

As described by the FDA, stability testing provides evidence of the effect of time and environmental factors on the quality of pharmaceuticals and medicinal products.  Such factors include light, humidity and temperature.  Stability tests also establish a re-test period for the drug substance or a shelf life for the medicinal product along with recommended storage conditions.

Stability tests are conducted in validated stability chambers such as manufactured by Norlake for pharmaceutical (ICH), biological (BOD), scientific and laboratory applications. These tests, which subject the product samples to variations in temperature and humidity, are conducted during drug product development as well as once a candidate drug reaches use and are governed by current good manufacturing practices (cGMPs). They are regulated in the U.S. by 21 CFR Part 211 Section 166. (www.gmp1st.com/drreg.htm#211.166)

Tips on Choosing a Laboratory Freezer for Vaccine Storage

Written by Rachel Kohn

Pharmaceutical laboratories, manufacturing facilities and healthcare providers must establish standard operating procedures to assure safe vaccine storage.   Because many vaccines must be kept frozen to maintain potency it is important to select the correct laboratory freezer and institute practices to be followed by laboratory or healthcare facility personnel responsible for vaccine storage.

Lab freezers as offered by Norlake and available from Tovatech come in several sizes. While size is important, the critical purchasing decision is deciding between a manual defrost laboratory freezer and an auto-defrost laboratory freezer.
