Compact in size, inexpensive, lightweight with low power consumption diode laser is housed in a plastic moulded case (90x90x42) mm approx., qualitatively used for ray optics demonstration and simple diffraction work as well as to indicate the points on overhead images and charts. It required three button cells to project visible red spot with a sharply focused beam of wavelength (630-680) nm with only 1mw power consumption.
A very efficient 12 V 100W quartz iodine lamp mounted in a well ventilated metal housing. Apertures 19 mm diameter are provided on two adjacent sides so that the lamp may be used either as an intense horizontal 'line' source, or end-on as a powerful 'point' source. The aperture not in use may be closed by a pivoted shuer equipped with a lock screw. The lamp house is mounted on a rod 160mm longx10mm diameter for supporng from an ordinary laboratory stand. Dimensions of lamp house 78x78x153mm. Supplied complete with 1mmowin cable

Overview:
Self-pressurized liquid nitrogen tank produces pressure by evaporation of little liquid nitrogen so that liquid nitrogen will exhaust itself and complement other containers. It finds its application in the transportation and storage of liquid medium (liquid nitrogen, liquid oxygen and liquid argon) and cold source of other refrigeration equipments. It is now widely used in tool and die industry, animal husbandry, medicien, semi-conductor, food, cryogenic chemical industry, aerospace, military and other industries and areas. (dewar flask, dewars, dewar, etc)
Production materials:
Inner and outer cylinders of the main body are made up of 304 austenite cryogenic special stainless steel of fine quality; absorbers are regenerated and activated; multi-layer insulation materials are oil-and-lipid-free thin imported composite.
Production technology:
All weld joints are tested by helium mass spectrometer; 100% of products have gone through strict cryogenic examination; unique patented vacuum-pumping technology ensures extremely evaporation loss rate; optional machine or digital display liquid level gauge; container shell makes use of unique polishing technology and has aesthetic modeling; the entire production process strictly follows is9001:2008 standards.
Security technology:
A two-way multi-layer security system is installed to ensure safety for production use; layout of the safety valve, outlet valve, vent valve, and booster valve is reasonable for secure and convenient operation.
