Description: There is a strong correlation between the pH of the body's internal environment and pH paper help you to maintain good healthy body by testing many usual everyday substances, including moisturized soap, lemon juice, milk, liquid detergent, moisturized soil, saliva, urine, sweat, etc. PH 1-14 color chart in each pack. The test strip color changes must be matched with the pH scale color chart within about 15 seconds. Paper Size approximately 45mm x 7mm (L x W). The scale reads from 1 to 14: • 1 - 3 indicates a very acidic substance • 4 - 6 indicates an acidic substance • 7 indicates neutral • 8 - 11 indicates alkalinity • 12 - 14 indicates a very high level of alkalinity Package Contents: • 20x 80 Packs of test strips Instructions: Strips can be dipped directly in liquid, but it is recommeded to place the strip on a dry flat surface and use an eye dropper or pipette to place a single drop on the strip. The color must be compared with the chart within 15 seconds. Discard used product.

An aquarium's water pH level is often overlooked as owners think that they've done all necessary steps to change the water and everything should be fine. But checking pH is very important as wrong pH causes stress among fish and can even cause illness to the point of death. Test your aquarium water to make sure it isn't too alkaline for your fish. Tropical fish like Tetra, Betta, Barb, Catfish, Bichir and Corydoras like pH in range of 6.5 to 7. A tank with higher pH may cause freshwater fish to be irritable or even fall ill. Ensure your tank's pH is correct with the test strips. In case it pH is higher, use SunGrow Mini catappa leaves to lower the pH. Sometimes, fish waste and plant decomposition can cause tank pH levels to drop to acidic levels of between 4.5 to 6.5. This can cause hard water fishes like Cichlids, Anabantids, Characins and Cyprinids to be irritable, fall ill or even die. Instead of changing the whole tank of water constantly, test your tank water frequently with SunGrow pH Test Strips. Please note that the ideal pH varies from fish to fish, so always check what is the natural pH value for your pet and then test it. Not only that, SunGrow pH Test Strips are suitable for resting a very wide range of products, including Soaps, aquarium water, drinking water, fruits and fruit juice, milk, oven cleaner, aquarium solutions, tea, soft drinks, urine, vinegar and bleach. Each box of SunGrow pH Test Strips contains convenient strips that change colour according to water's pH levels. Just use a spoon or saucer to take out a bit of tank water, dip one SunGrow pH Test Strip in it and shake off any excess water. Make sure the coloured sections are covered. Wait for 2 seconds until the coloured sections change, then compare it to the colour scale for your results. Quick and simple! It is an essential item to start your very own home aquarium laboratory kit.

Are you a "Supertaster?!" Test the phenotype and genetically-determined taste response your students, clients, and family to three different chemicals. This set includes one vial of vials of PTC, one vial of sodium benzoate, one vial of thiourea, and one vial of control paper. Each vial contains 100 papers. Each Super Taster Test Kit Includes: • 100 Strips containing Phenylthiourea (PTC) • 100 Strips containing Sodium Benzoate • 100 Strips containing Thiourea • 100 Strips containing NO chemical (Control) Approximately 25% of Americans are considered "supertasters" and, of this subset, people have varying levels of "supertasting" ability. "Supertasters" are people who have the ability to taste the substance Phenylthiourea (PTC). Some people cannot taste this substance at all and others can taste it distinctly. Whether or not a person is a supertaster (phenotype) is dependent on his/her genetics (genotype).

Turn Your Smartphone or Webcam into a Spectrometer The foldable paper mini-spectrometer folds up in minutes to transform your smartphone into a compact, simple, yet powerful experimental tool -- a visible/near-infrared spectrometer, also known as a spectroscope or spectrophotometer. This kit comes laser-cut from thick, light-blocking black card stock and includes a DVD (used as a diffraction grating), along with complete instructions for assembly, attachment to your phone or webcam, and calibration to take and share accurate spectra through open source software. Just add glue or tape! You can take an image through your spectrometer and upload it (Android or iOS 6+). What is spectrometry? What we perceive as a single color consists of multiple blended colors- just as green paint can be made from mixing yellow and blue paint. A spectrometer is a device that splits light into the various colors it is composed of, which we otherwise cannot distinguish with the naked eye. By viewing a substance through a spectrometer, one can distinguish the exact mixture of colors, which correspond to specific wavelengths of light. These can be compared to other spectra to help identify the sample.
