If you are preparing glucose standards in a lab to use with our Glucose Test Strips, in order for it to work properly, you must wait about 3 hours to allow mutarotation to occur. Solid [...]
If you are experiencing different results (taste of bitterness, then no taste at all) with the PTC paper, there might be a few explanations. Sensitivity to PTC is based on a genetic disposition, so it [...]
The Glucose test strips were originally developed to test for glucose levels in urine for educational purposes (not medical diagnosis). Other uses include osmosis experiments where a glucose/starch solution is used to demonstrate the concept [...]
The SDS for each taste test paper lists the ingredients. The concentration of ingredients is usually so small, it is less than what would be considered hazardous. Aside from these small quantities, the cellulose paper [...]
The Vitamin C test strip uses 2,6-dichlorphenolindophenol as a red-ox indicator. This indicator changes from blue to colorless as the amount of ascorbic acid (Vitamin C) increases. Unfortunately, this indicator also detects other acids by changing from [...]
Yes, we call it our Salinity Test Strip. This test strip measures the level of chloride present and can be used as an indirect indicator of sodium when the sodium is present due to sodium [...]
The taste test strips exhibit a taste due to a dominant allele on chromosome number seven, and the ability to taste these compounds is present in about 70% of the U.S. population. The ability to [...]
YES. In the case of the genetics taste test strips, both PTC and Sodium Benzoate are salts of benzoic acid. Any possible toxicity would be in grams per kilogram of body weight, which is millions [...]
Procedure: 1. Nutrient broth medium inoculated with Escherichia coli and Staphylococcus aureus and incubated at 37C for 24 hours, "starting cultures". 2. A standard plate count procedure performed using 24 hour cultures of Escherichia coli [...]
Glucose Apart from glucose, no other compound in urine is known to give a positive reaction. False positive reactions can be produced by a residual of oxidative compounds, from cleansing agents, for example. Larger amounts [...]
