PRODUCTS

  • Marki Microwave waveguide twists provide accurate offsets and directional changes for waveguide transmission lines and are built with high precision and then gold plated for high corrosion resistance.

  • Immunotherapy is an evolving and promising cancer treatment that works by stimulating the immune system. More biologically relevant human primary cells are now the chosen starting material for immunotherapy development. Historically, scientists routinely used immortalized cell lines in the research and development of therapies as they offer an inexpensive and stable platform. However, they are not fully representative of what is going on in vivo.

  • PHCbi brand’s 19.5 cu.ft. (554 L) pharmaceutical refrigerator with adjustable shelving and forced-air circulation help helps ensures uniform temperature control from 2°C to 14°C. The sliding glass door design minimizes air loss and supports easy access in high-use environments. A microprocessor controller and OLED display feature excellent visibility and intuitive operation utilizing control buttons that provide convenient, yet secure, user commands. Refrigeration temperature can be displayed in 0.1°C increments, and the minimum and maximum temperatures within the previous 12 and 24 hours are displayed. Audible and visual alarms with adjustable setpoints warn of deviations from setpoint temperatures, and all alarm conditions are displayed and recorded. A password-protected control interface assures operational security. Natural hydrocarbon refrigerants and inverter compressor technology deliver quiet, energy-efficient performance with fast recovery. ENERGY STAR® Certified.

  • Isolators with product protection as a housing for aseptic processes, e.g., filling, loading and unloading of freeze dryers.

  • The MM1-2567LS is a passive GaAs double-balanced MMIC mixer suitable for both up and down-conversion applications featuring excellent conversion loss, isolation, and a small form factor.

Catalysts

Catalysts work by changing the structure of a molecule or by bonding to reactant molecules causing them to combine, react, and release a product or energy.  For example, a catalyst is required in order for oxygen and hydrogen to bond, combine and produce water.

Catalysts increase the rate of chemical reactions. Unlike a reagent that gets consumed as apart of the chemical reaction, catalysts do not get consumed in the reaction. They can actually participate in multiple chemical transformations.Catalysts can be organic, synthetic or metal.

All processes need energy to take place. Processes require a very high level of energy in order to spark or start if a catalyst isn’t present.  When a catalyst is present the amount of energy required to spark the reaction is lowered and that makes the reaction happen faster and more efficiently.

Catalytic effects vary depending on other substances present that are a part of the chemical reactions. There are certain substances that can inhibit the effectiveness of a catalyst like poisons, and other substances that promote or increase the effect of the catalyst.  Inhibitors or negative catalysts are very important in medicine to treat mental illnesses, high blood pressure, cancer and many other diseases.

Catalysts are often used to help crack, or split, larger organic molecules like hydrocarbons into simpler molecules. It does this by breaking carbon-carbon bonds. The speed of the splitting process depends heavily on what specific catalyst is used and the temperature.  Applications of this technology include oil and petrochemical industries.
