VivaCare Ventilated Animal Holding Systems For Vivarium And Laboratory Animal Protection

Description

APPLICATIONS
There is ample evidence that airborne microbial contamination is a significant factor in the incidence of infection in laboratory animal colonies. It has been found that turbulent contaminated air in the animal holding environment is a major cause of infection.
The feeding and holding of Specific Pathogen Free animals demands an environment which is free from contamination in the form of bacteria, viruses and parasites. Immuno-suppressed animals such as nude mice must be kept in ultra-clean conditions.
Gelman SPF Series Class 100 Animal Holding Systems have been developed to meet the needs of such applications and utilise laminar flow principles to create an ultra-clean environment. Gelman SPF Series systems provide an extremely cost-effective alternative to the construction of a dedicated room.

OPERATION
Gelman SPF Series systems are self-contained, mobile laminar flow enclosures which incorporate an animal cage compartment with 3-adjustable shelves and 2-hinged PVC transparent doors.
Ambient air is drawn in through an easily accessible primary prefilter on top of the enclosure to remove gross particulates of 5 micron and larger.
The prefiltered air is biologically-cleaned by a HEPA filter which removes all particulate and biological matters down to 0.3 micron.
The HEPA-filtered air is introduced across the full length of each cage in all compartments in a horizontal air flow pattern.
The ultra-clean airflow which “bathes” the animals greatly reduces the concentration of airborne contaminants. Additionally the constant displacement of air from the cage compartment prevents the re-entry
of ambient contamination.
A secondary prefilter and an exclusive HMZD molecular carbon filter are installed to remove airborne particulates as well as odours and gaseous contaminants present in the exhaust air, preventing their escape into the laboratory.
An optional air heating system with thermostatic control can be installed to regulate the air temperature within the cage compartment.

APPLICATIONS
Infected animals pose significant risks for laboratory personnel and other laboratory animals. Applications involving the holding of
infected animals create a need for controlled environments, where contaminants such as infected faeces, urine, fur, sawdust and aerosols are arrested and contained.
Gelman ACU Series Infected Animal Containment Systems have been developed to meet the needs of such applications and utilize a
HEPA filter / fan system to extract air from cages which contain infected animals.

OPERATION
Gelman ACU Series systems are self-contained “100% exhaust” mobile enclosures which incorporate an animal cage compartment with 3-adjustable shelves and 2-hinged PVC transparent doors.
Ambient air is drawn into the cage compartment through small openings in the doors.
The inflow air is introduced across the full length of each cage in all compartments in a horizontal airflow pattern.
This constant inflow of air over the cages effectively creates a containment to ensure that aerosols released from the compartment are contained to protect laboratory personnel and other laboratory animals from the hazards of airborne infection.
The contaminanted air from the cage compartment is drawn in through an easily accessible prefilter to remove gross particulates of 5 micron and larger.
The prefiltered air is biologically-cleaned by a HEPA filter which removes all particulate and biological matters down to 0.3 micron.
An exclusive HMZD molecular carbon filter is installed to remove odours and gaseous contaminants present before the air is discharged into the laboratory.
