Carlisle Barrier System AMP2000 Glove BoxImage Coming Soon

Carlisle Barrier System AMP2000 Glove Box

Cambridge ID #: 11525

Features:

  • 4 glove isolator
  • highly aseptic environment for transfer of sterility test materials
  • The isolator has been designed with an emphasis on ergonomics and PLC control
  • Size of the isolator: 60”W x 26”D
  • Enclosure height: 30”
  • The operator will access storage shelves via three glove ports
  • Isolator construction is of 316L stainless steel with laminated safety glass windows, in silicone channel gaskets
  • An inlet and outlet blower system will exhaust hydrogen peroxide vapors through 2” automatic ball valves, controlled by the PLC for fully automated decontamination cycle with a VHP-1000 generator by Steris Corporation. Under normal operations, the inlet blower will slightly pressurize the isolator through HEPA filters, providing a minimum Class 100 environment.
  • Product and test materials are entered into the isolator via the large hatch back window and stored on shelves
  • After the window is sealed, the VHP decontamination cycle can be initiated.
  • Upon completion of the decontamination cycle, the operator docks the 350mm RTP beta flange to the alpha flange found on the work center (testing) isolator. The door is opened from the work center isolator. After the door is opened, the operator enters the glove ports and passes the required materials into the work center isolator for testing.
  • After testing, the operator passes media samples into the transfer isolator.
  • The transfer isolator is taken to incubators, where sealed media containers are removed from the isolator and placed into Amgen’s incubators.
  • Other waste material can be removed from the isolator and any cleaning can take place. The isolator will need to be decontaminated again for the next sterility test.

 Chamber Differential Pressure (DP) Controls

  • Sampling Method: Chamber pressure is sampled using  .250"OD X .125" ID polyurethane tubing. One pressure port on the transducer is terminated to a dedicated sense port penetrating the isolator chamber. The second pressure port is left open to the room. The pressure transducer is located to facilitate short tubing runs to decrease pressure drops and signal latency.
  • Set Point Variable (SPV): The operator is responsible for entry of the set point variable. This variable is the numeric value entered into the Phase Parameter Screen at the HMI. This value is considered the chamber's DP Set Point (DP SP).
  • Process Variable (PV): An appropriately ranged pressure transducer continuously senses the differential between the isolator chamber and the ambient or room air pressure. The transducer converts and transmits the air pressure signal to an electrical signal. The electrical signal format is typically a 4-20ma analog signal.  The 4-20ma signal is routed to an analog input at the PLC. The program will translate the electrical signal to a raw decimal value. This raw decimal value is considered the chamber's Differential Pressure Process Variable (DP PV).
  • Control Variables (CV): The PLC program will scale the process variable to appropriate units of pressure (typically INCHES of H2O). Each individual operating phase will use the scaled PV values & SP values for enabling pressure control logic & adjustment of outputs to associated devices, numeric or graphical displays at the HMI, and conditional logic for alarms.

Chamber Oxygen (O2) Controls:

  • Sampling Methhods: Two different methods of oxygen sampling are used by Carlisle Barrier Systems.The first and simplest method is continuous sampling.  With this method the oxygen sensor is directly located within the isolator chamber.  The transducer is then exposed to, and sampling, the isolator atmosphere at all times.The second method of oxygen sampling is to employ a sampling pump. With this method the pump pulls an air sample from the isolator chamber and passes the atmosphere sample past the oxygen sensor. The pump can then be enabled/disabled  for different phases of operation
  • Set Point Variable (SPV): The operator is responsible for entry of the set point variable. This variable is the numeric value entered into the Phase Parameter Screen at the HMI. This value is considered the chamber's O2 Set Point (O2 SP).
  • Process Variable (PV):  The O2 transducer continuously senses the chamber O2 level. The transducer converts and transmits the oxygen signal to an electrical signal. The electrical signal format used is typically a 4-20ma analog signal.  The 4-20ma signal is then routed to an analog input, at the PLC, where the program then translates the electrical signal to a raw decimal value. This raw decimal value is considered the chamber's O2 Process Variable (O2 PV).
  • Control Variables (CV): The program will scale the process variable to appropriate units of oxygen (typically % O2). Each individual operating phase will use the scaled PV & SP values for enabling control logic & outputs to associated devices, numeric or graphical displays at the HMI, and conditional logic for alarms.

 Chamber Relative Humidity (RH) Controls:

Sampling Method:The transducer is typically inserted directly into the isolator chamber. Unless otherwise capped off the transducer is continuously exposed to chamber atmosphere.

  • Set Point Variable (SPV): The operator is responsible for entry of the set point variable. This variable is a numeric value entered into the Phase Parameter Screen at the HMI. This value is considered the chamber's RH Set Point (RH SP).
  • Process Variable (PV): The RH transducer continuously senses the chamber RH level. The transducer converts and transmits the oxygen signal to an electrical signal. The electrical signal format used is typically a 4-20ma analog signal.  The 4-20ma signal is then routed to an analog input, at the PLC, where the program then translates the electrical signal to a raw decimal value. This raw decimal value is considered the chamber's RH Process Variable (RH PV).
  • Chamber Temperature  (Deg F) Control: The Chamber temperature is continuously sensed, translated to a 4-20ma analog signal, and input into the PLC thru an analog input. The temperature signal is then scaled accordingly, posted to the HMI screen, and compared to the appropriate temperature set point. If the controls and alarms are enabled, appropriate modifications are made to the temperature control signal, and alarm indications.

Chamber Temperature (Deg F) Control:

Sampling Method:The temperature transducer is inserted directly into the isolator chamber. Unless otherwise capped off the temperature sensor is continuously exposed to the isolator atmosphere. When RH sensing is present on the isolator, the temperature sensor is typically combined with this sensor. If there is no RH sensing present then an independent temperature-sensing probe is used. Without RH sensing present, the sensing transducer is typically an industrial RTD. With RH sensing present the sensing transducer is typically an integrated chip (IC).

  • Set Point Variable (SPV): The operator is responsible for entry of the set point variable. This variable is a numeric value entered into the Phase Parameter Screen at the HMI. This value is considered the chamber's RH Set Point (RH SP).
  • Process Variable (PV):  The RH transducer continuously senses the chamber RH level. The transducer converts and transmits the RH signal to an electrical signal. The electrical signal format used is typically a 4-20ma analog signal.  The 4-20ma signal is then routed to an analog input, at the PLC, where the program then translates the electrical signal to a raw decimal value. This raw decimal value is considered the chamber's RH Process Variable (RH PV).

Chamber Vaporized Hydrogen Peroxide (VHP) Level

Sampling Methods: Sampling pumps are used to pull a small portion of the isolator's atmosphere past the VHP sensor(s). The sampled atmosphere is pumped through .250"OD X .125" ID VITON or TEFLON tubing passed by the VHP sensor and returned to the chamber.  The sample pump(s) are configured to run based on different the different conditional requirements for each phase of operation.

  • Set Point Variable (SPV): The operator is responsible for entry of the set point variable. This variable is the numeric value entered into the Phase Parameter Screen at the HMI. This value is considered the chamber's VHP Set Point (VHP SP).
  • Process Variable (PV):  The VHP transducer continuously senses the VHP level present in the sampling system. The transducer converts and transmits the VHP signal to an electrical signal. The electrical signal format used is typically a 4-20ma analog signal.  The 4-20ma signal is then routed to an analog input, at the PLC, where the program then translates the electrical signal to a raw decimal value. This raw decimal value is considered the chamber's VHP Process Variable (VHP PV).

 

Chamber HEPA Pressure Level

Sampling Method: Chamber inlet and exhaust HEPA filter pressure is sampled using  .250"OD X .125" ID polyurethane tubing. The pressure transducers are continuously exposed to chamber atmosphere.

  • One pressure port on the each respective pressure transducer will be terminated to a dedicated pressure sense port on the "non-chamber side" of the inlet or exhaust port HEPA filter. The second pressure sense port on each respective transducer will be tee'd together and terminated to a dedicated pressure port penetrating the isolator chamber. This tubing method generates a differential pressure measurement acrossed the HEPA relative to chamber pressure.
  • Set Point Variable (SPV): The operator is responsible for entry of the set point variable. This variable is the numeric value entered into a Phase Parameter Screen accessible from the HMI. The set point variable associated with the HEPA filter pressures used only for alarm functions.
  • Process Variable (PV):An appropriately ranged pressure transducer senses the resulting differential pressure. The transducer converts and transmits the air pressure signal to an electrical signal. The electrical signal format used is typically a 4-20ma analog signal.  The 4-20ma signal is then routed to an analog input, at the PLC, where the program then translates the electrical signal to a raw decimal value. This raw decimal value is  the HEPA filter Differential Pressure Process Variable (HEPA DP PV).

Control and Indications Variables

As stated above control function associated with HEPA filter pressure variables is limited to alarm. 

Chamber Vapor Level

  • Sampling Methods: The vapor sensor is directly located within the isolator chamber.  Unless otherwise capped off, the transducer is exposed to, and sampling, the chamber atmosphere at all times.
  • Set Point Variable (SPV): The operator is responsible for entry of the set point variable. This variable is the numeric value entered into the Phase Parameter Screen at the HMI. This value is considered the chamber's Vapor Set Point (VPR SP).
  • Process Variable (PV):  The vapor transducer continuously senses the vapor level. The transducer converts and transmits the vapor signal to an electrical signal. The electrical signal format used is typically a 4-20ma analog signal.  The 4-20ma signal is then routed to an analog input, at the PLC, where the program then translates the electrical signal to a raw decimal value. This raw decimal value is considered the Vapor Process Variable (VPR PV).
  • Control  and Indication Variables (CV): The program will scale the process variable to appropriate units of vapor (typically % vapor). Each individual operating phase will use the scaled PV & SP values for enabling control logic & outputs to associated devices, numeric or graphical displays at the HMI, and conditional logic for alarms
