Each Test Paper variant is tailored for its intended purpose relevant specific areas of science or laboratory work. These are used in fields such as chemistry, biochemistry, nutrition, environmental science, etc. 

  1. Ascorbic Acid Test Paper:  Used for qualitative analysis of the presence or concentration of ascorbic acid (Vitamin C) in a solution
  2. Cobalt Chloride Test Paper: Can accurately identify the level of moisture present with a humidity level of 50% or higher
  3. Congo Red Test Paper: Used to test narrow-range acidic solutions for metal plating where pH values are very low (pH 1.0-3.0)
  4. Fluoride Red Test Paper: Detects Fluoride in steps of 0, 10, 25, 50, and 100ppm. The tested solution must have a pH of 0.5.
  5. Lipid / Fat Test Paper: Detects the presence of Lipids: Fats, Oils, Waxes. This may include hydrophobic molecules, sterols, and fat-soluble vitamins, including Vitamins A, D, E, and K, as well as Cholesterol.
  6. Glucose Test Paper: Detects 0.1 – 2.0% glucose. This tool is ideal for determining glucose levels in experiments involving osmosis and diffusion, as well as educational urine analysis and food science studies. 
  7. Lead Acetate Test Paper: Detects Hydrogen Sulfide in water in concentrations as low as 5ppm
  8.  High-Level QAC Test Strip: The High-Level QAC Test Strip (Quaternary Ammonium Compounds) measures the range of 1-1500 ppm in increments of 200, 400, 750, 1000 and 1500 ppm, and gives results in just seconds. Check for higher levels of QAC when testing stronger solutions that kill pathogenic organisms, as opposed to testing for residual QAC with our Low Level QAC test strip, or our standard QAC Quick Response Test Strip.

Little Small On The Wrist
Really cool timepiece, been loving timex a lot recently, this is me coming over Casio/G-shocks. Although it is a bit smaller on the wrist it still looks very nice and I really love the gray and like green color contrast. Really easy to read the time as well.

Sturdy and digital
This watch has “ fake screws” holding the band on . The band is actually held on by the usual pins holding it on most watches but weaker . The pin came off while I was putting it on for the first time! This is the second time I bought off Amazon in 2 weeks where the watch appeared to be sturdy and the pins fell off . Going back to military watches that have material straps that go completely around wrist and do not have pressure on pins

Ten years of ownership…Thank you, Timex!
Color: Black, Size: One Size
Solid watch for everyday wear. I have worn this watch for over 10 years. I let a watch shop replace the battery about every 18 months. Other than the original band (which lasted 5 years) I have had zero problems. Still looks great, rugged and manly😇 Overall I recommend this watch for its value, reliability, simple clear design, legible hands in all light conditions. Great watch!!!

Solid Watch for Everyday Casual Wear
Color: Black, Size: One Size
I have purchased this item other times and I’m quite satisfied with wearing this watch everyday with casual wear. The size is just right not too small or large.
