    List price: $5.50
    Brand: LabRat Supplies
    Model: LRS-4812

    This product contains two packs of 100 pH strips, 200 strips in total. Each strip is made of premium grade litmus paper intended for universal application. To test the pH of a solution simply dip the pH strip into your solution and the strip will change color. Quickly match this color against the color chart provided to obtain your solutions pH. Please see our infographic or scroll down for a list of common uses and examples of pH. To further the reliability of our products we randomly test each shipment we receive across multiple pHs to ensure product quality.

    Instructions:
    1. Take one strip from the pack and dip it into the solution you would like to measure. The color of your strip will change immediately.
    2. Quickly match this color against the color chart on the inside of your pack to obtain the pH. Do not wait or let the strip dry!
    3. The number next to the color on the chart is your pH. The pH scale ranges from 1 (very acidic) to 14 (very basic), 7 is neutral.

    Please note that solutions with a pH of ~5.5 will result in a yellow colored test strip that resembles the original color of the dry strip.

    Store in a cool, dry place away from sunlight.

Slides are composed of optical glass for clear viewing and are 3 x 1 x 0.4 inches/75 x 25 x 1mm (H x W x D, where H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) The set comes in a fitted wooden case to prevent breakage and ease handling.

    Slide specimens include coprimus mushroom (cross section), dense connective tissue (section), dog cardiac muscle (longitudinal section), dog esophagus (cross section), dog skeletal muscle (longitudinal section and cross section), dog stomach (section), honeybee worker leg-composite (whole mount), house bee mouth parts (whole mount), human blood (smear), hydra (longitudinal section), Hydrilla verticillata leaf (whole mount), Lilium anther (cross section), Lilium ovary (cross section), nymphaea of apustio stem (cross section), onion epidermis (whole mount), pig motor nerve (section mount), pine leaf (cross section), pine stem (cross section), pumpkin stem (cross section), rabbit spinal cord (cross section), rabbit testis (section), sunflower stem (cross section), Tilia stem (cross section), young root of broad bean (cross section), Zea stem (cross section).

    Microscopes are instruments used to enhance the resolution of an object or image. Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are used to display an image on a monitor, rather than looking through a lens. Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying magnification abilities. Magnification ability refers to the size of an image. Resolution, also known as resolvant power, refers to the clarity of the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can control magnification through a fixed focus, or through a range of adjustments. They can also utilize LED, fluorescent, and mirror light sources to help control viewing capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.

    United Scope manufactures microscopy equipment and accessories under the brand name AmScope. The company, founded in 1996, is headquartered in Irvine, CA.

    100 Bartovation Chlorine Test Paper Strips For Testing Sanitizer Strength, 10 - 200 ppm

    100 Bartovation Chlorine Test Paper Strips For Testing Sanitizer Strength, 10 - 200 ppm Lowest new price: $7.29
    List price: $9.99
    Brand: Bartovation

    Chlorine Test Paper

    This Chlorine Test Paper provides a simple, reliable, and economical means to measure the concentration of free available chlorine in sanitizing solutions.The Chlorine Test Paper measures total available chlorine from 0-200ppm, and give results in just seconds. Total available chlorine is the sum of free available chlorine and the combined available chlorine. Our chlorine test paper is most often used to test the strength of solutions used to sanitize surfaces, for example, in the restaurant industry. In these types of applications, bleach is usually used to generate the available chlorine.

    When using bleach as a cleaner, it must be diluted before use, and it will work best in the pH range of 5-7.

    Instructions:

    1. Use dry fingers to remove a chlorine test paper strip from the vial.
    2. Dip the test strip into the solution to be tested, and do not agitate.
    3. Remove and compare to the color chart immediately.

    NOTE: The strip will darken over time, so it is best to compare to the color chart as directed. In addition, if two strips are stuck together, the color will be darker. Lastly, if you lay the strip against the vial when comparing to the color chart, it will also darken the color. The color chart was created by holding a strip in the air next to the vial.

    NOTE: If you believe that the solution contains chlorine, but the test the strip is white after dipping, you may be seeing what is referred to as the "bleaching out effect." At high concentrations of bleach, the available chlorine will overwhelm the indicators used in the strips. If this happens, instead of developing a purple color the strip will very quickly turn to white. The best indicator of this effect is the presence of a thin blue line on the strip separating the wet portion from the dry portion of the strip.

    Features:

    • Perfect for testing chlorine sanitizers and avoiding hefty board of health fines!
    • One pocket sized, splash proof, lightweight vial protecting instructions and color chart with 100 pre-cut strips
    • Industry leading rapid one second test
    • Tests in a range of 10-200 ppm (10, 50, 100 and 200 ppm markings)
    • These are NOT for pool OR tap water tests. They ARE designed specifically for restaurants testing their chlorine sanitizers
