pH Combination Electrode Replacement
Gel­filled combination pH electrode. Standard BNC connector. pH range of 0–14. 34" cable.
Electrolyte Solution, Saturated
Saturated potassium chloride solution for refilling and storing pH electrodes. Intended to be placed directly into the refill port of elec­ trodes. 100­mL bottle.
Low Ion pH Test Kit
High­quality water may not have enough ions to provide a reliable pH value. If you use standard pH indicator paper, the indicator in the test paper may be the only contaminant present when you dip it in the water, resulting in an erroneous pH value. This low ion test kit provides you with a sample tube, special low ion test paper (roll of 25 feet) and a color comparison chart. Unlike most test paper, this paper is not to be dipped. Place the paper in the sample tube and add your unknown liquid. Cap the tube and shake, then read the pH value by holding the tube against the color comparison chart.
Phosphorescent Materials
Phosphorescent Flash Paint
No mess, no mixing, no excess paint—just open the jar, stir, and start painting! Our special mixture gives the brightest glow possible for your flash screen. One 200­mL jar will cover about 20 square feet. Great for demonstrating the principles of phosphorescence.
See free video at flinnsci.com.
Phosphorescent Vinyl Sheet
Glow­in­the­dark vinyl sheet gives off a yellow­green glow upon absorption of light. Simply place an object, such as your hand, on the vinyl sheet and expose it to light. Turn off the lights, and remove your hand from the sheet. The area where your hand was will remain dark while the region of the sheet that was exposed to light will phospho­ resce, or glow in the dark! In a darkened room, exposure to a camera flash will provide the same glow. Great for demonstrating the principles of absorption and emission of light, particularly the process of phospho­ rescence. Material has an adhesive backing and can be easily cut with scissors. Each sheet is 12" x 12".
Use different color LED micro lights with the phosphorescent vinyl sheet to demonstrate the effect of wavelength on light energy and phosphorescence! For free activity instructions, please contact Flinn Scientific and request Publication No. 10978, Phosphorescence and LED Lights.
