Researchers, attending veterinarians and facility managers are often faced with the difficulty
of transporting lab animals in situations ranging from moving through non-lab animal corridors to moves involving many miles and the complex mission of protecting both the animals,
technicians and the public. This is further complicated by multiple species, health status,
different primary containment and distance.
Let’s look at each factor separately. One cart may need to transport NHPs one day and rats
the next. Here the cart will most likely need adjustable shelving. Other multi-species factors
to consider: are the NHPs in squeeze cages, simple transport cages or stereotactic apparatus? In order to fulfil multiple objectives, the chamber of the chart needs to be of sufficient
size to accommodate the situation. Each transport cart from Park Bioservices is built to
accommodate facility specific requirements. Full customisation is available at out of the
In order to determine whether simple passive or powered filtration is required, distance
and duration are the key concerns. A short trip down an interior corridor probably doesn’t
require a blower and power airflow. A simple passive filter is all that is needed. A trip
cross-town in a van will require more stringent airflow specification. If the cart needs to be
powered, how long will it run before needing recharging? Are electrical outlets available
at both ends of the transport route or will it be self powered for the entire trip? Short or
long trips can be successfully completed if the parameters are known in advance. There
are multiple power options available when designing a cart: passive filter media (think
rodent shipping crate filters), 12 volt marine deep cycle battery powered blowers, 120 volt
blowers that run on standard electrical outlets but can also automatically switch to backup
power when disconnected. If this option is selected, typically APC battery backup units
are used to power the blower. If the cart will be multi-purpose, then the longest distance
will dictate the choice of power. In addition, filtration cart design is dictated by the facility
or facilities it moves within. Doorway widths, corridor configuration, elevators, ramps and
vehicles all need to be factored in.
We also need to protect both the transported animal’s health, other animals in the facility,
technician and the public. If infectious animals or germ-free and immune compromised
animals are transported, high levels of filtration will be required. Except in the case of passive filtration carts, we use HEPA filters which are 100% tested to IEST standards. In most
instances, the Park Bioservices filters will last in excess of five years.
Park Bioservices can work with you to plan the cart design and provide a CAD rendering
of the cart we propose to build. This helps ensure that all requirements have been addressed
and the cart will fulfil its mission successfully.
