But you also can’t just toss your samples into a bucket or container of liquid. Instead, calibration gases scientists are using special containers, known as liquid nitrogen dewars. These dewars are for the safe, secure containment of liquid nitrogen. They just have to have strong walls and keep everything in them secure.
Many differing sample types can fit into liquid nitrogen dewars. They are handy for storage of 580 valve cells, tissues, DNA, and RNA, and so on and valuable for science studies.

You must also ensure that the dewar is always topped off with sufficient liquid nitrogen, to freeze and preserve the samples.

So, what do scientists do with liquid nitrogen dewars and why are they so important? They help keep biological coherent laser samples fresh and ready for analysis.

This allows researchers to trust that the results they get from their studies are good and true, as the samples are being kept frozen and are well-preserved.
For Liquid nitrogen dewar storage, leaking gas is one of the major issues. Therefore, we perform leak tests more than five times to ensure quality. We have a complete manufacturing line and strict quality control along with a set of after-sales services. We ensure that our clients receive top quality products.
