The coarse emulsions and nanoemulsions were placed in Falcon™ 15 mL conical centrifuge tubes, which were subsequently left at two temperature conditions (60 °C ± 2 °C and 4.0 °C ± 0.5 °C). For this, each thermal condition was varied every 48 h for 2 weeks, starting at 60 °C for the first 48 h, then at 4 °C, etc. The stability parameters evaluated were creaming index, droplet size, viscosity, zeta potential, electrical conductivity, and pH.
15 ml conical centrifuge tubes
Manufactured by BD
The 15 mL conical centrifuge tubes are laboratory equipment designed for use in centrifugation processes. They have a capacity of 15 milliliters and a conical shape that facilitates the separation of samples during centrifugation.

Preparation of G-CHO dispersions in different solvents. Dispersions of G-CHO adducts were prepared at different concentrations: 1 mg/mL; 0.5 mg/mL; 0.3 mg/mL; 0.1 mg/ mL. Each dispersion was sonicated for 30 min using an ultrasonic bath (260 W). The dispersion (10 mL) of each sample was put in a Falcon™ 15 mL Conical Centrifuge Tubes and centrifuged at 6000 rpm for 30 min. Evaluation of the dispersions' stability was qualitatively performed by putting a light at the back of the glass tubes, visually inspecting the dispersion after 3 days at rest. In this way, settling could be easily detected.

We chose
two natural water samples to analyze
using our sensor. The pond water sample was collected from Burnet
Woods pond (Cincinnati, OH, August 9, 2013). River water sample was
collected from the Ohio River (Newport, KY shore, November 30, 2012).
Both samples were collected in conical tubes (Falcon 15 mL conical
centrifuge tubes), at least 10 mL volume. Samples were diluted with
0.2 M borate buffer (pH 9.0) by a factor of 2, which yielded pH 8.96.
Samples were analyzed immediately upon completion of dilution using
the method of standard additions discussed below.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
