FLEX-A-SCOPE, A STACKABLE ALUMINUM LABORATORY MANIFOLD

File0001

Manifold as used in a laboratory environment is defined as a pipefitting with several lateral outlets for connecting one pipe with others. In various lab settings, it is necessary to utilize manifold as a means of carrying building services such as nitrogen, oxygen, water, compressed air, vacuum and carbon dioxide to individual lab spaces from a remote storage area.  This is necessary for two reasons: First, it is hazardous to locate gas cylinders in a laboratory area, and secondly, it is a waste of valuable floor space. Well designed gas delivery systems provide safety, efficiency, aesthetics and cost-efficiency.

Flex-a-scope is a stackable, aluminum manifold that provides a safe, attractive delivery system for house services.

Phenolic Resin Countertops

WHAT ARE PHENOLIC RESIN COUNTER TOPS?

  Phenolic Resin is a plastic-like material formed from a chemical reaction between a carbon based alcohol and an aldehyde.  Aldehydes are organic chemicals with the     structure of R-CHO, which is a carbon double bonded to an oxygen center (a formyl group), which in turn is bonded to hydrogen and a side chain.

. In the mid 1900’s this material was mixed with wood fibers and heated to high temperatures, forming a strong plastic-like polymer. This was used to make handles for cooking utensils and ovens, as well as other household items, such as the phone below. This early plastic was called Bakelite. phenolic-resin-image

  Today, phenolic resin is made by compressing many layers of paper and impregnating them with the liquid resin under high heat and pressure conditions. The result is a relatively light weight, chemical resistant product that can be fabricated into tops, cabinets, and shelving.

Phenolic resin countertops are often used today in place of the traditional black epoxy resin tops in hospitals, restaurants, schools and many laboratories.

Polypropylene Fume Hoods

      Fume Hoods are always a fixture in industrial and academic settings to capture and exhaust toxic vapors which result from experimentation in a laboratory. Their most important function is to protect the student or technician, as well as the environment. However, there are many instances where the reagents or products also require special conditions, whether it be increased ventilation, or a completely non-metallic work surface. Trace Metal Analysis and High Acid Digestion are two systems where a polypropylene hood is necessary for precise, safe testing.
Trace Metal Analysis to identify trace metals in various materials to the ppm, ppb and ppt level has many applications. Medical laboratories do blood and urine testing to detect toxic or deficient levels of particular metals in the body. Marine biologists look for trace metals in algae and other aquatic organisms to determine the effect of their presence on growth and proliferation. Forensic scientists can treat skin with a test solution and illuminate residual metal with UV light, determining the presence of metal, the type, weight and duration of contact. These analyses are so precise that the experimentation must be done in a completely non-metallic environment.

      Likewise, High Acid Digestion is used to analyze soil and rock samples by first dissolving silicate minerals. Basically, it is a process which breaks down a complex substance into volatile gases and simple salts. Various chemical methods can then be used to accurately determine the concentration of each element. Digestion techniques can also be used to test the integrity of plastic laminate materials used in industry and construction. Fume hoods with metal components are contra-indicated for these types of analysis due to potential corrosion.

Polypropylene fume hoods and casework are also appropriate for industries using  sophisticated electronic and semiconductor equipment.

Saving Energy with Smart-Sash®

Fume hoods are essential components of research facilities, whether they be pharmaceutical, medical, industrial, biotechnical or education-based. They serve multiple purposes, the most important being to protect workers in the lab from breathing harmful vapors. Unfortunately safety comes at a price, and it has been estimated that one fume hood running for 24 hours a day uses as much energy as two single homes.

In order to maximize energy conservation and increase laboratory safety, Jamestown Metal Products has developed Smart-Sash®. This is a fully automated, programmable system which opens and closes the sash completely hands free. Whenever a researcher enters the designated field of operation in front of the fume hood, the sash will automatically open, and likewise will close 15 to 20 seconds after technician steps away. This eliminates the uncontrollable human factor, optimizing safety and efficiency.

 

 

Features include:

  • Electronic gear motor coupled to the chain and sprocket sash counterbalance system.
  • Direct drive to sash chain allows smooth uninterrupted up and down motion.
  • Sash closes within 20 seconds after operator leaves the front of the hood.
  • Able to be retrofitted on JMP or non-JMP bench hoods.
  • Operator can stop the sash opening at any time and re-position manually.
  • Meets ANSI/AIHA Z9.5-2003 specifications.
  • Minimizes exposure by returning the sash to the closed position when not in use.
  • Low volume audible pulses alert operator of sash closure.
  • Prevents cross contamination between hoods.
  • Up to $2,561 annual savings per hood.
  • Aerodynamic sash handle allows for the containment of harmful fumes during rapid sash movement.

    From organic chemistry experiments in a university setting, to drug synthesis in a pharmaceutical lab, Smart-Sash® is unparalleled in its increased safety, efficiency and energy conservation.

Redefining Physics Tables

As you may, (or may not) remember from physics class, Galileo introduced a formula that predicted the motion of an object moving down an inclined plane, and he was the first to account for a frictional force affecting the velocity, although only in a theoretical sense. His theory was the basis for Newton’s First Law of Motion and the concept of inertia. Creating a frictionless surface for experimentation has since been achieved in various ways, most recently by the Naval Research Lab which built a 37 ton air hockey table to test a new satellite docking system.

        During the planning phase of a recent high school science lab renovation, the AP physics teacher asked if there was a way to make an air hockey-like table that could be used for “frictionless” experiments. LF Systems designers, together with this innovative teacher, expanded this idea to create lab tables for everyday class work that could all be easily transformed into frictionless surfaces. Using the ultra-level qualities of Trespa phenolic resin, the uniform air movement of tubeaxial fans and vibration damping swivel leveling mounts, these classroom worktables easily become frictionless experimental work stations. They can be used alone or configured together to create a  larger working area.

       The type of investigations that can be done is limited only by the imagination. Straight and orbit velocity, angle of inclination, and collision between pucks of varying mass are just a few of the frictionless experiments the physics teacher designed for his students.
