NPL has excellent liquid Nitrogen & liquid Helium producing units. It is also having a 6000 litres capacity liquid Nitrogen storage vessel, making the availability of liquid Nitrogen round the clock for NPL’s scientific work. We are also maintaining and producing liquid Helium at NPL. Till 31st Dec, 2007, we have produced approximately 31200 litres of LN2 & supplied approximately 2400 litres of liquid Helium and Helium gas. Efforts are being made to improve the productivity further.
