Barrier Isolator


Barrier Isolator

Isolator essentially means a physical obstacle between a process and its operator. A Barrier isolator is closed system whose size and features depends upon the type of application. Simple or complex operations can be undertaken either manually or automatically. Flawless functioning and optimum performance best define our range of Barrier isolators.

Specifications :
  • Efficient to be used under positive and negative pressure
  • Provided with well-designed motor and blower
  • No exchange of air with the surrounding environment

Isolator Applications Requirements for Containment processing :
  • Generally operated under negative pressure to ensure max. operator safety.
  • Negative pressure isolator is basically used for powder handling process and highly disperses products
  • Well Designed capacity of motor and blower as per sufficient airflow requirement.
  • They must not exchange air with the surrounding environment(except through a HEPA filter)
  • Equipped with nitrogen supply if required
  • Negative pressure of -100 Pa, Pneumatically controlled interlocked isolator door after startof operation
  • visual display indicates permanent status of the isolator
  • radii in the isolator chamber >15 mm
  • tightness test before each process
  • push –push” system for exhaust air filters
  • integrated rapid transfer ports (RTP) for loading and discharging without compromising the surrounding
  • Negative isolator basically used for Sampling, Dispensing, Quality checking, product charging, Filtration, Drying, Milling, sieving, Blending, Solution Preparation, Weighing and R & D purpose.

Isolator Applications Requirements for Aseptic Processing :
  • Generally operated under positive pressure to ensure maximum product safety.
  • Positive pressure isolator is basically used for Sterile Operation.
  • Exhaust system will be based on recirculation basis.
  • Well Designed capacity of motor and blower as per sufficient airflow requirement.
  • They must not exchange air with the surrounding environment except when that air passes though a HEPA filter.
  • Typically classified as ISO 5 (Class 100, Grade A)
  • In cases of applications with hazardous bacteria, subsequent biological decontamination can be carried out by means of gaseous hydrogen peroxide (H2O2) or UV radiation.
  • Positive isolator basically used for sterile transfer, filtration, sterility testing, loading and unloading of vials into lyophilizers and compact filling lines.
