For instance, if you need to measure 100 mL of water exactly, grab a volumetric flask. Understanding the function of each piece allows you to work more efficiently and accurately. So, how does ...

Therefore, the quantity of ammonium nitrogen is a routine examination for the monitoring of surface water and wastewater in China. The development of a sensitive and selective analytical method for ...

CPLA was synthesized in two steps via a one-pot approach. In the first step, a 500 mL round-bottom flask was charged with 300 g of l-lactide (20 mol equiv), 18.14 g of 1,10-decanediol (1 mol equiv) ...

2022; Zertal et al., 2022). 1,10-decanedithiol (9.5 ml, 43.7 mmol) was added to a solution of NaOH (18 g, 450 mmol) in methanol (300 ml) using a 500 ml round bottom flask equipped with a compressed ...

Lipid was then measured by weighing the residue. The lipid was accurately weighed and then transferred into a 25 mL measuring flask with a volume of 5 mL 1% internal standard tritridecanoin solution ...
