Safety cabinet/ laminer flow for transformed bacteria?

Please refer to the following link -

Intro to Biological Safety Cabinets

In general - it sounds like you need a Biosafety Cabinet Class II Type A2. This is the most common microbiological safety cabinet and will protect both the user and the product.

To summarize the referenced link above here is some pertinent information regarding selection of biological safety cabinets...

How Biological Safety Cabinets are Classified

Classification Biosafety Level Application
Class I 1,2,3 low to moderate risk biological agents
Class II 1,2,3 low to moderate risk biological agents
Class III 4 high risk biological agents

Here is the air flow diagrams some of the common Class II biosafety cabinets:

Hi
Most of the transformed bacteria are handled at biosafety level ( containment) 2.Its not only to protect user and product but protection of environment is also includedas they generally carry some or other antibiotic resistance gene plus some foreign gene. Depending on the type of gene transfected it is further categorized into higher level or sublevels. But level 2 is minimum.
Person handling them should have minimum training in handling, discard etc.

The biological safety committee of your organisation should be able to advise you on what biosafety level you should be working at when you submit a risk assessment of the proposed research.

I recommend you to visit www.biobase.cc.Or send e-mail to eval(unescape('%64%6f%63%75%6d%65%6e%74%2e%77%72%69%74%65%28%27%3c%61%20%68%72%65%66%3d%22%6d%61%69%6c%74%6f%3a%6d%69%63%68%61%65%6c%5f%62%69%6f%62%61%73%65%40%79%61%68%6f%6f%2e%63%6e%22%3e%6d%69%63%68%61%65%6c%5f%62%69%6f%62%61%73%65%40%79%61%68%6f%6f%2e%63%6e%3c%2f%61%3e%27%29%3b'))
