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.

Nice upgrade 51mm for me
Color: Silver
This is my second 51mm machine. I never used the included handle or basket… I kept my existing HUGH IMS precision basket and bottomless portafilter. The temp and preinfusion are set and not adjustable but fine (reduced variables). I defeated the shut off by volume by setting higher than needed (wish that was easier to turn off). I like to manually shut off when I hit 30g on my scale. The machine will drip since there is not solenoid valve so I just pull the scale from the try when mouse tail breaks and drip starts. The steam wand and hot water dispenser is a massive upgrade (from Capresso EC50) and the real reason for my upgrade. I would have paid $50-100 more for the improvements listed… but I guess most people would not so this is about the best option for me with 51mm (keeping all the 51mm three lug portafilter stuff I own). 5 stars = for me and the price
