Precision Labs Protein Test Strips (Pack of 50)

Precision Labs Protein Test Strips (Pack of 50) Lowest new price: $19.95
Lowest used price: $9.95
List price: $19.95
Brand: Precision Laboratories
Model: 83337

The Protein test strip detects residual Protein in water in increments of 0.3, 1.0, 3.0, 10.0 plus g/L. If used to test protein in urine, the color may be more green than blue. If testing urine samples, consider using the Urine Analysis Test Strip. The Protein test strip is based on so-called “protein error of indicators”. This phenomenon relates to the fact that certain pH indicators will change the color at a different pH value in the presence of protein then in the absence of protein. The test is more sensitive to albumin than to globulins, mucoproteins, hemoglobin and Bence-Jones protein. The Protein test strip is strictly for use in education and training students in all levels of medical and clinical-biochemical educational programs. It is not for use in the medical field. Instructions: Remove one Protein test strip from the vial. Do not touch the test pad with your fingers. Dip the test strip into the solution being tested for 1 second. Remove and compare to the color chart after 60 seconds.

Features:

  • For use in education and training students in all levels of medical and clinical-biochemical educational programs
  • Detects residual protein in water in increments of 0.3, 1.0, 3.0, 10.0 plus g/L
  • Protein test strips provide students with hands-on experience testing protein levels of liquid solutions
  • The test is more sensitive to albumin than to globulins, mucoproteins, hemoglobin and Bence-Jones protein
  • Comes with 50 strips in a vial with flip-top lid
