With a rated output of 80 watt, this source provides sufficient intensity of white light for almost any experiment
Same as wooden box for sodium vapor lamp but slightly smaller
Metal box wiht piano type on/off switch. Out put is through a 3 socket. The trnsformer is auto leak type and gives starting voltage of 440V which reduces itself when the lamp glows.Available : 35 / 55 wallt.
Low Pressure lamp giving spectral lines in 58890 A and 58950 A wavelenght range.Available : 35 / 55 Watt
To determine absorption spectrum of lodine vapour
Supplier: Electrical, electronics and semiconductor related equipment and spare parts, super high pressure capillary mercury lamp, xenon lamp, mold release agent, rust preventives, laboratory related equipment and spare parts
Wooden box with slits on three sides to perform 3 experiments at a time, each slit has two riders to adjust the lenght of slit or close it when no experiment is being performed.Regular quality made of ordinary wood.Deluxe quality made of superior wood and has different sized slits for different experiments. The height of the box can also be adjusted to suit the requirements of the experiment
1. Transparent quartz glass tube Smooth, colorless and transparent, high purity íí(sio2í¦99.99%), corrosion-resistant (expect hydrofluoric acid), high temperature-resistant (intenerating point 1730íµ), good thermal-stability, good light-penetrability (over 93% of visible light), crystal capability(6 hour under the temperature 1400í+5íµ,crystal thickness is less than 100 micron), good insulating-ability, long-life and non-contaminative. Mainly used in protection of heaters, production of halogen tube, lamps. 2. Desoxy transparent quartz tube Nice appearance, good thermal property and mechanical strength, strict tolerance and low hydro-(í_5ppm).Used in mercury lamp, metal halite and other quartz lamps. 3. Non-ozone transparent quartz tube It can prevent high-density ultraviolet radiation by being added titanium-oxide with colorless surface and light-purple section. It can almost prevent ultraviolet radiation no more than 220nm, while penetrates over 83% of 253.7nm, which have strong bactericidal ability. So ití»s called "bactericidal" and "non-ozone" quartz. It is widely used in bactericidal lamp, treatment of water and so on. 4. Uv-filtering transparent quartz tube It has colorless or light-blue surface and light-purple section. Besides common property, it can filter ultraviolet radiation of 190-320nm to prevent harm to bodies. It can be used in most kinds of environmental lighting products.
