Cleanroom Tape is critical for minimizing contamination in a cleanroom environment.  It works well on metals, plastics, and other materials.  The tape pictured on the left is made from nonvinyl polyolefin film.  The properties feature a super-clean, acrylic, pressure-sensitive adhesive.  What  sets it apart from your standard run of the mill hardware or office supply store tape is  it’s characteristics of being Chemical- and moisture-resistant and performs extremely well in a wide range of temperatures.   The Superior adhesive bonding characteristics are maintained for a prolonged period.  Width Size comes in 1″, White, Blue & Clear. 

PCX™ Cleanroom Tape, (pictured on the right) can be used for sealing, labeling, masking, and various other tasks within the cleanroom that requires pressure-sensitive qualities. The properties are Low-density polyethylene.  This means, low in halogens and leachable chlorides. The special construction lessens the chance of outgassing and provides  excellent chemical resistance and good conformability. To insure that the tape is as safe as possible, it’s packaged in a cleanroom with special processing to ensure low extractable ions, down to parts per billion.  I guess it doesn’t get much cleaner than that!  Size by width runs between 3/4″ up to 3″ in a variety of colors.

The Center for Disease Control or CDC estimates that food borne illneses are responsible for 76 million people per year in the United States becoming sick, 300,000 hospitalized, and 5,000 deaths.  Food can be a medium for transmitting disease.  Foodborne illnesses normally result from pathogenic bacteria or their toxins being present during processing, handling, or preparation.  Food handlers can transmit opportunistic pathogens associated with the human body like Staphylococcus aureus or intestinal bacteria because of unsanitary practices such as failure to wash their hands before preparing or handling food.  Botulism food poisoning results from ingesting a toxin produced by Clostridium botulinum when its endospores grow in improperly home canned foods.  The endospores occur in the soil and the environment and contaminate the prepared vegetables.  Salmonella and Campylobacter are associated with poultry and eggs and can cause illnes if these foods are not properly prepared.  Special care must be taken when preparing foods in order to reduce the bacterial counts of pathogenic bacteria.

One of the things that I love about my job,  is that I’m always learning about new products and solutions.  .

Hopefully, if you have found this blog, it’s not because you’re in the middle of a crisis involving a vacuum leak on a pump.  But should that be the case, look no further.  Apiezon Sealing Compound has a putty-like consistency, used to fill gaps and joints on the rotary side of a vacuum system.   It is designed to form a seal around flat, unground joints.  Keep in mind, this is a temporary fix, depending on the application. 

An example of use might be sealing glass cylinders to metal plates.   It is used for vacuum work where low vapor pressures are not required. 

The sealing compound softens between 40-50 C (104-122 F).  Maximum temperature usage is 30 C (86 F).  The Vapor pressure is 1x1o-4 Torr at 20 C (86 F).

The compound is easy to mold, easy to apply and maybe more important, easy to remove. 

For movable joints, Apiezon makes a   high temperature and ultra-high temperature grease.  Designed for lubricating, though the grease is silicone free.   Used in vacuum systems such as desiccators, rotary evaporators, vacuum traps, and ground glass joints.

As always, our knowledgeable Staff would be happy to assist you with finding the right fix and to answer any questions that you may have.

NovaClean, is a floor cleaner manufactured by Micronova, intended for use in a Clean-room environment.  This is actually an all-purpose clean-room detergent which can be used on most floors, walls, ceilings and clean-room curtains.  The features that sets it apart from most other commercial and industrial cleaners is its Low-ionic concentrated formula, which will not generate a static charge or affect the efficiency of conductive flooring.   When used at recommended dilutions, both the sodium and potassium levels are detectable in only parts per billion.  NovaClean is Biodegradable.   To insure that it retains its properties, NovaClean is filtered, filled, and bagged in a clean-room environment.  NovaClean is a concentrate that will yield between 60 – 128 gallons of cleaning solution per gallon container.

Please note that NovaClean is NOT a disinfectant.  It was initially formulated for the Semiconductor and Electronics Industries.  It’s super fine purity and filtration lends itself to applications for both the Pharmaceutical and Bio-tech industries.

Studies show that if you are currently using DI Water or IPA, adding a small amount will break surface tension and remove more particles.  This will assure that you’re not bringing more into the clean-room than you’re taking out.

NovaClean is available in Quart, Gallon and 5 Gallon containers.  We encourage you to call our knowledgable staff with any questions that you may have.

Bacteria of the genus streptococci differ from staphylococci for two main reasons:  they lack the enzyme catalase and they occur in chains rather than in clusters.  Catalase degrades hydrogen peroxide into water and oxygen.  The streptococci often times cause mixed infections with staphylococci but they independently can cause diseases such as pneumonia, meningitis, endocarditis, pharyngitis, erysipelas, and glomerulonephritis.  Streptococci occur naturally in the pharynx and mouth where they are found on the sufraces of teeth, tongue, cheek, throat, and in saliva.  The streptococci of the greatest importance to humans are S. pyogenes, S. agalactiae, and S. pneumoniae.  Several systems have been used to classify the streptococci.  One of the first was proposed by J. H. Brown in 1919 that was based on the ability of these bacteria to cause lysis of red blodd cells when grown on blood agar.
