Students can test solutions for acid or base determination. Easy-to-use red litmus paper turns blue for bases and blue litmus turns red for acids. 100 strips of each. Not for measuring the pH of natural waters, such as streams, rivers and lakes. To measure pH in these waters, try our Water Chemistry Test Strip, pH 6-9, item 652729 or, for a wider pH range, our LaMotte Water test kit, item 652927, pH 3.0-10.5.

Product Description: A TDS meter (aka ppm pen, nutrient tester, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the TDS-3 can tell you your overall water purity level, which will be displayed on the screen in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O. The TDS-3 is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.) The TDS-3 is a great tool for drinking water, water filtration and purification, colloidal silver, hydroponics (test your nutrients), aquariums, RO/DI systems, pools and spas, commercial and industrial applications and more. The TDS-3 is a rugged model that includes a protective carrying case. This is the world's most popular handheld TDS meter for industry professionals.

A glass hydrometer is the most efficient way to determine the sugar or potential alcohol content of beer or wine. A hydrometer works by measuring the amount of dissolved solids in a liquid before and after fermentation to determine the potential alcohol content. This particular hydrometer is a triple-scale hydrometer that displays sugar content in the 3 most common ways. The first is the specific gravity scale of .990 - 1.170 which measures sugar solutions as compared to the density of water. This scale is most commonly used by brewers. The second scale is the Balling Scale (also known as Brix) which measures sugar as a percentage of total weight ranging from 0 to 38%. This is most commonly used by wine makers. The third scale reflects the potential alcohol that can be produced based on the sugar content of the liquid which ranges from 0 to 22%. This scale is applicable to both beer and wine making. As a result, this hydrometer is versatile enough to measure any beer, wine or cider that is up to 22% potential alcohol. Made in the USA. Dimensions: Length: 10.13 inch (25.7cm) Diameter (at narrowest point): 0.25 inch (6mm) Diameter (at widest point): 0.75 inch (19mm) Working Range: Specific Gravity: 0.990 - 1.170 (0.002 Resolution) Balling (Brix): 0 - 38% Sugar (0.05% Resolution) Potential Alcohol: 0 - 22% (1% Resolution) Calibration Temperature: 60°F Item Includes: 1 - Glass Hydrometer 1 - Set of Instructions 1 - Plastic Storage Container and Cap

Why do I need these tests? An estimated 9 million visits to GP's each year are due to vaginal discharge, irritation or discomfort. Many women continue with discomfort hoping the problem will go away. Immediate and effective treatment can be obtained from a local pharmacy or doctor based on the test results. Bacterial vaginosis (BV) or disturbance in the vaginal milieu is diagnosed in approximately 15-20% of all pregnant women, thereby increasing the probability of an infection and, as a consequence - premature birth - chorioamnionitis - premature rupture of the amniotic sac - fever during childbirth - postpartum endometritis - a bacterial infection of the newborn infant. Through regular self-testing of the vaginal pH value, expectant mothers can reduce this risk! The tests is for women who sense their vaginal discharge is abnormal.

Refractometer calibration solution is used to accurately calibrate your refractometer for testing natural sea water or synthetic sea water. Specifically manufactured for calibrating refractometers for use in testing natural or synthetic sea water. Clean refractometer prism slide with clean fresh water. Dry completely with a soft clean cloth. Place a few drops of ACPTM Refractometer Calibration Solution on the prism slide. Allow 45 - 60 seconds if ATC (automatic temperature compensating) refractometer is used. Calibrate to 35 ppt. Clean refractomer prism slide with clean fresh water to remove RCSTM solution. Dry with a clean soft cloth so the prism slide is dry. Add a few drops of your aquarium water on the prism slide. Allow 45-60 seconds ATC refractometer is being used. Read the amount of dissolved salts in your aquarium water. Clean refractometer prism slide with clean fresh water after each use. For best results calibrate with RCSTM prior to each use. Note: Using RO or RO/DI water to calibrate a refractometer at -0- will yield inaccurate results when testing marine aquarium water in the 35 ppt. / SG 1.026 rangs.

Use this to calibrate your Brix refractometer, Salinity refractometer, Beer refractometer, Honey refractometer, Clinical refractometer, Coolant refractometer, Alcohol refractometer, battery refractometer, or antifreeze refractometer. It works on all types of refractometers. Very simple to use! Open the daylight plate, and place 2-3 drops of this calibration fluid on the main prism. Close the plate, looking into the eyepiece and turn the calibration screw until the boundary between the upper blue field and the lower white field meet exactly on the ZERO scale. It's done! The whole calibration will only take 30 seconds. The Vial contains 2ml, it is enough for at least 30 calibrations. Satisfaction guaranteed or your full money back!

This product contains one case of 100 plastic pH strips. Each pH strip has four pieces of pH paper that will change color after being submersed in a solution. After submersion the strips can then be compared against a color chart to determine the pH. This method allows for fast and accurate pH readings. To further the reliability of our products we randomly test each shipment we receive across multiple pHs to ensure product quality. Instructions: To determine the pH of your solution simply take one pH strip and dip it into the solution for 1-2 seconds. Wait for up to 15 seconds and then match your strip against the color chart that's provided on the case to determine the pH.
