    EZ-Campy System

    Campylobacter jejuni is a Gram-negative microaerophilic organism, which means it has a requirement for reduced levels of oxygen. It is relatively fragile, and sensitive to environmental stresses (e.g ., 21% oxygen, drying, heating, disinfectants, acidic conditions). Because of its microaerophilic characteristics the organism requires 3 to 5% oxygen and 2 to 10% carbon dioxide for optimal growth conditions. This bacterium is now recognized as an important enteric pathogen.

    Surveys have shown that C. jejuni is the leading cause of bacterial diarrheal illness in the United States. It causes more disease than Shigella spp. and Salmonella spp. combined.

    FAQ's

    How does the EZ-Campy System work?

    For microaerophilic conditions the EZ-Campy System removes half the air in the jar one time and replaces this with anaerobic gas mixture.

    Is a Jar Gassing System right for me?

    While obligate anaerobes should be processed using an anaerobic workstation, a jar gassing system is suitable for facultative anaerobes and microaerophiles. The evacuation and replacement method is considered to be the most efficient way to create microaerophilic conditions within a gas jar. The EZ-Campy System produces conditions this way without any of the disadvantages of gas generating envelopes. There is no chemical waste and condensation levels are much lower, so plates are more convenient to handle and read following incubation.

    **Microbiology International does not recommend jar gassing systems for the isolation of obligate anaerobes. Anaerobic jar gassing systems require users to inoculate samples and handle the agar plates on the bench at atmospheric oxygen levels which can reduce the recovery rates for a range of clinically significant strict anaerobes. Jar gassing systems are suitable for facultative anaerobes and microaerophilic samples. An anaerobic workstation is recommended for strict anaerobic samples to insure maximum recovery, isolation and identification.

    Accessories

    Microbiology International offers two different types of anaerobic jars, plastic or stainless steel, that are compatible with your EZ-Campy System. The plastic jars have a 9-plate capacity and the lids are fitted with carrier clips for catalyst sachets used for anaerobic cycles. The jars will vent automatically if too much pressure is applied.

    Plastic Anaerobic Jars

    The stainless steel jars are available with a 9-plate capacity or 48-plate capacity. They are the most durable jars offered, and are constructed to last sample after sample. The lids are fitted with carrier clips for catalyst sachets used for anaerobic cycles. The jars will vent automatically if too much pressure is applied.

    Options and Specs Images and Video

    Microbiology International can now offer the unique Whitley Internal HEPA Filtration System to provide a high degree of product/sample protection on Whitley Anaerobic Workstations. HEPA fitted workstations are ideal for use as part of a pharmaceutical manufacturing process, for the cultivation of slow-growing anaerobes, or for applications requiring complex manipulations under anaerobic conditions (ie biochemical assays).

    Using innovative circulation technology, all the atmosphere in the chamber passes through the filter every four seconds, quickly creating and maintaining a particle-free environment (tested down to 0.3μm – exceeding ISO 14644 Class 3, as referenced in the Cell Tissue Culture Directive, or Class 1 of US Federal Standard 209E). Unlike some other systems, Microbiology International integrates the filter within the workstation.

    To introduce samples or equipment, the built-in, 12 liter, rapid-cycle airlock has the capacity to introduce up to 40 Petri dishes into the workstation in 60 seconds. There is also the option to specify the 15cm letterbox, ideal for quickly transferring all sizes of dishes and small items.

    Whatever your application, we can tailor the Whitley A35 Workstation to your requirements. For example, if you want to be able to use electrical equipment inside the chamber, you could include the option of a built-in, interior electrical socket. If you require the ability to thoroughly sanitize your workstation between experiments or need to introduce large items of equipment, you may want to specify the removable front option.

    A35 Front Options

    From a relatively small footprint we have been able to maximize incubation capacity to create the perfect environment, whether for a few plates or hundreds of plates.

    The Whitley A35 Anaerobic Workstation is the latest innovation in workstation technology from Don Whitley Scientific. Complete with a built-in, rapid airlock and intuitive touch-screen control panel, this new workstation allows you to work completely glove and sleeve-free.

    Anaerobic Conditions
    Monitoring System
    This factory-fitted option monitors and displays real time oxygen levels within the workstation. Depending on the percentage of oxygen present, the chamber/airlock symbol on the touch screen will read green, yellow or red. The electronic Anaerobic Conditions Monitoring System is complete with oxygen sensor and a special software package. The oxygen sensor is located inside the chamber for accurate, real-time readings. The sensor is easily and quickly calibrated via the touch screen.

    Gas Pressure Monitor
    Designed as a method of monitoring the gas supply. The system will indicate the status of both sides of the switchover: FULL – IN SERVICE, and DEPLETED. When a cylinder or cylinder bank is depleted, the green light will change to a red light, and the audible alarm will sound.
