Strangely enough I am also a 53 year old adult, although male, and I had a great chemistry set as a kid. I was also looking for a set to bring back a few memories, but the modern versions are so safe and boring
Why is the measurement of absorbance unitless? Define the term self-absorption used in chemistry. How does Atomic Absorption Spectrometry/Spectroscopy (AAS) differ from the flame tests and the chemical tests? What are some possible applications for flame tests, chemical tests and AAS...
What are the uses of a burette and a pipette? How are the two different from each other? Why is the bicarbonate in blood an effective buffer when its pKa is 6.1, while the pH of the blood is 7.4? What would be the best way to determine how the frog population is affected by pH ...
Fluorescence in situ hybridization is a technique that is used for the spatial detection and quantification of nucleic acids in their cellular environment. It has emerged as a powerful cytogenetic method for the analysis of cells and tissues on the transcriptome and genome level with more than 6 ...
for instance, it is not possible to weigh anything on a ship. We therefore have to weigh chemicals in advance of the expedition or, if possible, pipette them on board.” And because many measuring instruments are sensitive to vibrations, Koch and his team have to carry out a lot o...
That is a relevant advantage of the nanoLC-EI-MS over the most commonly used nanoLC-ESI-MS [88]. Additionally, EI interfaces can effectively analyze analytes that do not ionize in ESI. However, it is essential to note that inefficient desolvation can reduce the ionization process and ...
Using chemical genetics in Arabidopsis, BA:GUS reporter has been successfully used as bait for the identification of inhibitors of auxin transcriptional activation [42]. 2.1.1. The Signalling Reporter DR5 and Variants The most popular auxin reporter to indirectly visualise auxin in plants is the ...
Three respirometers with glass tubes, a stopper and a pipette fitted to the stopper Six balls of absorbent cotton Round, wooden stick Ice Water bath Red food coloring 100mL graduated cylinder 15% potassium hydroxide (KOH) Safety goggles Lab coat Protective gloves The respirometer is used to meas...

Equipment is machinery or tool that is made to perform specific function/work so as to aid or enhance the production of goods. This is used to perform a specific activity or operation. It is used to refer to plant, machinery, instrument, tool, etc....
