I've given you reasons why you need to purchase a new biosafety cabinet, and the Top 5 Signs that you should service or replace your BSC. And when you decide to buy a new one, I've given you the features you should look for - Ergonomic Design, Excellent Performance, Safety and Health Features, Savings and Services.

But do you already know what classification and type of BSC you will buy? Or are you sure it will fit in your laboratory? 

Worry no more. In this blog, we will cite the essential questions you should ask when buying a biological safety cabinet. Hope you find it helpful!

1. What needs to be protected? This will help you determine what type of BSC you need. Do the samples/ specimens/ cultures need to be protected from environmental particulates? If no, then a Class I BSC will do. If yes, a Class II or III are the most appropriate. 
2. What are the different types of work to be done in the cabinet? Are chemicals involved in your application? Take note that hazardous (toxic or volatile) vapors are not filtered by the HEPA/ ULPA filters found in BSCs. In most cases, a Class II Type A2 with thimble duct can be used for microbiological work involving hazardous chemicals. Class II Type B2 is only needed when you have a large opened container, more than 4 liters total, of hazardous chemicals. See blogs: The biosafety cabinets are on Viber Parts 1, 2, 3, 4, 5 and 6. 
3. What are your size limits? Do you have enough space in your lab? You should know the maximum space allotment so that you don't end with a BSC that is too big for your lab, or so small that you can't work. Consider also this question, will the BSC fit on hallways, doors, elevators and other paths? Makes sense, right?
4. Does your procedure require modifications to the equipment? Consider other optional accessories or service fixtures needed. If the unit requires an exhaust system, is there an appropriate location for the cabinet and its ductwork? Consider also other uncommon modifications to the cabinet. BSCs should be built to an appropriate standard and listed by a testing agency. Some modifications can lead to the equipment being unsafe. Remember, you use a BSC for safety purposes - this should not be compromised.

5. How much does it cost? This question is tricky. We know cost is always a concern. Avoid looking at the price tag of a BSC; inquire instead about the lifetime cost of each BSC - energy-savings, services and warranty, and a proven track record. Consider also how much will you spend in annual certifications and maintenance.

So when buying a new biosafety cabinet, make sure you have definite answers for the questions above. Good luck and happy shopping!
