5 Features of a Perfect Laminar Flow Hood For Labs

Laminar flow hoods are essential for all lab work, especially in molecular biology. They remove potential contaminants that might yield false positive results in a PCR. In addition, they can help maintain temperatures within a safe but rigorous range to induce the desired reactions.

If you need to purchase one of these expensive machines, it’s always a good idea to know what makes up the best laminar flow hood for labs and how the features contribute to making them effective. Some of these features are shared here for your consideration:

  1. Low Temperature

The laminar flow hoods keep laboratory work safe but not too low temperatures. They are designed to contain temperatures ranging from 85-95 degrees Celsius. They maintain constant temperatures at temperatures such as 37 degrees Celsius, 40 degrees Celsius, or 42 degrees Celsius.

  1. Moisture Removal

All laminar flow hoods are designed to remove moisture from lab air. This is usually accomplished through fans that blow across humidifiers attached to the interior sides of the hoods. These electric fans pull moisture out of the air and then use the heat to evaporate it. So when you are out there to Buy Laminar Flow Hood for your laboratory, then make sure to check its moisture control settings.

  1. Powerful Air Blower

It is essential to have a powerful air blower that can also deliver a consistent flow of aerated air over the area covered in the laminar flow hoods. The blowers used in these units are usually capable of delivering clean and sterile air for working in labs and for testing purposes. Aeration will also play an important role in keeping labs safe and clean by eliminating contaminants that might remain invisible to the naked eye.

  1. Hood Size

It’s important to have a laminar flow hood that covers a sufficiently large area. The size of the hood determines the extent of work it can accommodate. For example, smaller units are suitable for tube filling and small-scale work, while larger ones accommodate various works, including PCR testing and DNA extraction.

  1. Process Controls

These switches and other controls can be used to monitor and control lab processes using laminar flow hoods. These are usually inside the hoods but may vary from unit to unit depending on their age and model. The narrow passages in these units provide some degree of barrier against dust particles and bacteria as well as providing an obstruction for some gases such as carbon dioxide, oxygen, and nitrogen that might hinder working conditions in the lab.


The above features of laminar flow hoods are essential to ensure that samples in your lab are safe and reliable. Of course, having the perfect one that matches your expectations is a matter of some research, but the above features give you an idea of what to look for when buying one.
