About us
A high-tech company that supplies cryogenic equipment and instruments
Company introduction

'Physics Instruments (Shanghai) Limited is a high-tech company committed to  supplying cutting-edge ultra-low temperature systems and Instruments applied in the fields of basic physics theory study and frontier technology exploration.


Our company has established a good cooperative relationship with Leiden Cryogenics B.V.(Leiden for short), a famous dilution refrigerator manufacturer who leads in ultra low temperature fields.


Authorised by Leiden, Physics Instruments (Shanghai) Limited undertakes selling and market promotion for all the models of Leiden’s dilution refrigerators in China.


Being committed to the belief of honesty,Physics Instruments would like to cooperate with all the partners for mutual benifits. As a member of the society, We would also like to make our own contribution for the good and continuous development of the world.

Leiden Introduction

Leiden Introduction

Leiden Cryogenics was built by Prof. Frossati from famous Kamerlingh Onnes Lab at Leiden Univeristy


Prof. Giorgio Frossati has done research in quantum fluids and solids, ultra-low temperature techniques and lately spherical gravitational wave detectors.


 Worked on dilution refrigerators since 1970 having introduced the silver powder heat exchangers, now widely used in all commercial dilution refrigerators.


 He has built a DR system using silver heat exchangers that obtained a world-record lowest continuous temperature of 2.0 mK in 1977 when he worked at the National Center for Scientific Research in France. Before that he had developed plastic heat exchangers that improved the world record from 7 to 5.2 mK. When he moved to Leiden in 1980 he built the up to now still most powerful dilution refrigerator for low millikelvin temperaturesand improved the world record to 1.8 mK in continuous operation.


 Plastic dilution refrigerators for using in high field magnet and pulse magnet had US patent in 1993 

(Patent No. US5189880,  Grant Date: 02.03.1993).
