Our experience of 40 Years brings innovation to you

UltraSafeClass II biological safety cabinets deliver maximum safety, comfort

and convenience. Featuring an advanced design for easy operation and maximum safety,our UltraSafe cabinets may be used wherever protection is of paramount importance insafety levels 1 to 3, including research, pharmaceutical quality control labs, pharmacies,and clinics/hospitals.

Superior Personnel and Product Protectionwith best-in-class air flow and filter technology.

Exceptionally Comfortableergonomic design prevents user fatigue and promotes safe

working habits.

Maximized Energy Efficiency for environmental protection and significant cost savings.

Features.

1. A clever interlocking switch design prevents accidental exposure to UV light. Should the front

window be opened whilst the cabinet is in use an override program ensures your safety by

automatically adopting a class 1 bio-safety mode. This feature will auto-cancel when the front

window is closed again.

2. The modern, proven control panel provides one touch access to all functions including servicing.

A fully integrated self-diagnostic processor with digital status display backed up by an audible and

visual alarm guarantees your safety.

3. An internally mounted, exhaust HEPA filter adds to the stylish features and modern design of the

cabinet by freeing the outer shell from protrusions.

The supply filter provides ISO Class 3 (per ISO14644.1) and US Class 100clean air to the work surface in a

gentle vertical laminar flow for product protection.

4. The work area is large, airy and bright. Light pours in through large toughened glass sides and a wide

pneumatically assisted front window.

UltraSafe.5. An ergonomically designed sloping front

and new flat front intake grille allows for optimum

operator comfort and prolonged use with ease.

With the BSC work surface height at 900mm above

the floor, and the seat heights set as above, the reach

onto and over the work surface can be estimated

when reaching into the cabinet at the arm extension

of 120. Generally speaking, the farther a person can

reach into the BSC without awkward positioning, the greater flexibility and access that person has to the interior

workspace.

These guidelines on proper seat adjustment, while relating to only one aspect of BSC ergonomics, will allow the

user to optimize the work height of the cabinet in order to maximize reach and usability of the BSC. The

UltraSafeBSC, when optimized as a complete workstation, will accommodate one of the farthest reaches into

the working chamber of any BSC offered today.

6. A large front opening (210mm) provide a comfortable and easy working access for the operator whilst

still ensuring sterility and containment.

7. Heavy gauge stainless steel and superior materials are used throughout. Direct drive fans (2 or more),

dynamically balanced for vibrations free operation, ensure large flow reserves for years of trouble-free

operation.

8. All electrical components installed during manufacturing are CE Compliant in accordance to current

EN Standards.

UltraSafe.Performance and reliability are guaranteed by full compliance with AS 2252 Part 2. 2009

All components meet or exceed applicable safety requirements.

Each cabinet is individually factory tested for operational performance and electrical safety.

Documentation specific to each cabinet serial number is maintained on file

The newUltraSafe cabinets also meet and exceed the performance requirements of EN12469

& NSF 49-Annex F. safety and performance requirements.

Inflow of room air enters the front air grille to establish operator protection;

room air does not enter the work zone, preventing product contamination.

The inflow velocity, down flow velocity,

airflow path and intake geometry are

precision tuned and tested to create an optimum

air curtain on the front aperture, this curtain

maintains personal and product protection

even in the unlikely event of a severe inflow or

down flow imbalance that, would compromise

protection in a conventional cabinet.

The combination inflow and down flow air streams

forms an air barrier that prevents work surface emissions from

escaping the work zone.

AbstractThe aim of this project is to investigate the various methods

sed indetermination air barrier containment of BiologicalSafety cabinets and validate their effectiveness. The Projects

esearch showed that the aerosol test used in determination

f the air barrier containment should be endorsed in the

Australian standard as a valid method of testing.

IntroductionBiological safety cabinets have proven to be an essential

em of equipments inside any research and or diagnosticsaboratories. Our dependency on them has improved

rastically. Cabinets are essential component in handling

iological hazardous materials. It is the only mean of safety

rom getting infected with dangerous substance that

ontribute to a high death rate that can be prevented simply

y just using proper biological safety cabinets. Thisesearch focused on the air flow inside the cabinet and how

could affect the air barrier at the sash of the cabinet. In

ddition to establishing a methodology of validating theAerosol test.

MethodsTest 1

Setting up the cabinet according to the Britishstandard.

Test the cabinet using potassium Iodide Discusmethod. Examine the environmental factors thatmay affect the cabinet.

Examine and observe the droplets affect of the KI.Examineand observe the droplets affect of the KI. scrutinize the effectsof varying the velocity of the main fan motor and the exhaustfan motor on the performance of the air barrier and on theperformance of the potassium iodide discus results.Investigate the operator protection factor.

On the original setting of the cabinet in accordance to theBritish standard test the cabinet using the smoke generatortest (the aerosol test). Examine the outcomes and correlatethe results.

Determine the differences and the similarities and determineif the test pass or fail. Enhance the photometer with the useof particle counter in order to achieve a quantitative results.

Repeat the test with setting up a cabinet in accordance to theAustralian standard then start to test it using the potassiumiodide discus. Produce a graph of comparison of the suitable

air velocity that could be used where both tests fails/ passes.

Outline the findings in terms of performance and airvelocities.

Test 2:

Scattering effect around the cabinet.

Use a die to observe the scattered potassium iodidearound the cabinet.

Is it sufficient to test the centre only?

Move the sampler of the KI discus towards the side ofthe cabinet and carry out a test. Work out the operatorprotection factor at the new positions of the samplers.

Correlate the results obtained versus the resultsobtained from testing at the centre only. Investigate theareas where the barrier is vulnerable.

Validation and Comparison Results

ConclusionThe Key factor or controller of the air barrier is the exhaust

fan motor. The barrier is maintained proportionally to theadjustment of the exhaust fan as shown from the results.

lowering the air velocity of the main fan interrupt the barrier,

and raise the main issue of cross contamination inside the

cabinet. From the comparison performed, Aerosol liquid test

provide better qualitative method of testing the air barrier

since it cover lots of aspects of practical informative method

of test. KI discus test can not be carried out at any laboratory

since it could contaminate the work in the actual laboratory.

In contrast to aerosol test which doesnt interfere with the

nature of work carried out in the laboratory.
