Functional description

Presentation

“Pharmaceutical manufacturing evolves from an art to a science”.

This sentence alone from the FDA Guideline “Pharmaceutical cGMP for the 21st century – A

Risk-Based Approach” summarizes the current revolution in the Pharmaceutical industry.

Conscious of these changes and remaining attentive to its customers, bioMérieux decided to

improve its Air IDEAL 3P aerobiocollector in order to best respond to these new needs.

Air IDEAL 3P was thus developed and validated in order to provide a tool to the

pharmaceutical industry that would guarantee a scientifically proven method of air sampling.

Air IDEAL 3P evidently remains perfectly suited to the enumeration of airborne

microorganisms in less demanding work environments such as agribusiness.

In addition and in order to continue its universal application, Air IDEAL 3P is still available in

two versions:

−

one for the use of culture media in 90 mm diameter Petri dishes,

−

the other designed for use with 65 or 70 mm plates.

The aspiration flow-rate of Air IDEAL 3P is calibrated at 100 L/min with an impact velocity of

less than 20 m/s. According to good sterilization practices, the sampling grids can be

sterilized in an autoclave, see section "Sterilization of grids" on page 5-1.

Operating principle

Air IDEAL 3P is an impaction aerobiocollector, used to detect the presence of viable

microorganisms in the environment to be tested by precise sampling of a given volume of

air.

Air is taken up with a turbine through a grid surface. The acceleration of airflow results in the

impaction of airborne microorganisms on the agar. Passage of the air through the grid filters

out particles, thereby facilitating the enumeration of CFU (colony forming units) after

incubation of the medium.

A reading and statistical correction table is used to convert the number of CFU to the most

probable number of microorganisms collected per m of air.

Presentation

Performance

The performance characteristics of an aerobiocollector depend on its capacity to collect

microorganisms in the air without compromising their viability during impaction on the agar.

This property can be obtained only with a perfect compromise between the high aspiration

velocity leading to effective collection, and a sufficiently low impaction velocity to guarantee

the revivification of collected microorganisms.

Air IDEAL 3P was developed in close cooperation with aeraulics experts in order to

optimize this ratio.

Since the industry has increasing needs for scientifically proven methods, bioMérieux

*

commissioned two recognized independent organizations* to validate the physical and

biological efficiency of Air IDEAL 3P.

Collection efficiency validated according to the ISO 14698 standard

Air IDEAL 3P was third party validated by the Health Protection Agency (UK) to meet the

requirements of ISO 14698-1 for the control of clean rooms. Both the physical and biological

efficiencies of the equipment have been validated according to this standard.

Physical efficiency testing approach

The physical efficiency of an air sampler for collecting airborne bacteria is evaluated by

comparison with a membrane filter sampler. Uniform particles of different diameters

containing bacterial spores of Bacillus subtilis var niger were generated in a controlled room.

The physical efficiency of Air IDEAL 3P was determined by comparison with the membrane

filtration standard operating side-by-side.

Biological efficiency testing approach

Air sampler inefficiency can either be due to a failure of the sampler to capture particles

containing micro-organisms (physical loss), or to inactivation of viable micro-organisms

during collection, so that formation of visible colonies on agar will not occur (biological loss).

To address this point, Air IDEAL 3P was evaluated for recovery of a mixture of Bacillus

subtilis (standard indicator for physical loss) and Staphylococcus epidermidis (standard

indicator for biological loss).

The ratio of S. epidermidis / B. subtilis for the test samplers was divided by the ratio

obtained with the reference standard membrane filter sampler to give a comparative

biological efficiency.

U s e i n g l o ve b o x e s

In order to be used to test glove boxes, the design and materials

Air IDEAL 3P had to be entirely reviewed in order to optimize system air tightness.

of

In addition and in order to guarantee the optimal operation of Air IDEAL 3P in this

application, the system underwent a complete validation in a glove box (SKAN AG, model

ARIS glove box).

Ap p l i c a t i o n s

Air IDEAL 3P enables the precise and reproducible sampling of air. The volumes taken can

be set in 10 L steps up to a maximum volume of 2000 L.

This sampling range enables Air IDEAL 3P to be used in all types of environments, from

sterile zones to more contaminated surroundings and in all applications, e.g. qualification of

sterile rooms or daily monitoring.

Recommendations for installation and use

Recommendations for installation and use

• Install the instrument on a flat, perfectly horizontal surface, on its tripod or by its hook.

• Avoid locations directly exposed to sunlight, excessive heat, damp or dust.

• The instrument must not be used near strong sources of electromagnetic interference.

• Do not use the instrument with its original protective cover cap, but with a grid.

IMPORTANT!

When the instrument is used for the first time, it is imperative to perform 1 battery

charge-discharge cycle.

• Charge the battery for 14 hours.

• Discharge the battery by performing successive sampling (see page 3-25

"Battery autonomy test (Menu 6)").

• Recharge for 14 hours.

• Make sure the grid holes are not blocked.

IMPORTANT!

Air IDEAL 3P is delivered with a hook for suspending it in a glove box during

decontamination phases. Even though sampling can be done while suspended, it is

preferable to position Air IDEAL 3P along the axis of one-way flow at the air outlets.

This configuration is the worst case scenario since the air sampled has swept the

entire volume of the glove box before emerging.

Do not obstruct the air outlet during use to respect operating parameters.

sampling cycles of less than 1000 liters, it is advisable to put the battery on charge as soon

as the flashing symbol appears:
