Furthermore, needle gauge or the dimensions of the glassware also affect drop volume. To improve reproducibility, experimental procedures also note the total amount of time required to add the liquid or another measure of addition rate. In a related usage, the amount of a reagent, whose precise quantity is unimportant, will sometimes be given ...
An oral syringe is a measuring instrument used to accurately measure doses of liquid medication, expressed in millilitres (mL). They do not have threaded tips, because no needle or other device needs to be screwed onto them. The contents are simply squirted or sucked from the syringe directly into the mouth of the person or animal.
A conical measure is a type of laboratory glassware which consists of a conical cup with a notch on the top to allow for the easy pouring of liquids, and graduated markings on the side to allow easy and accurate measurement of volumes of liquid. They may be made of plastic, glass, or borosilicate glass. The use of the conical measure usually ...
Reagent testing is one of the processes used to identify substances contained within a pill, usually illicit substances. With the increased prevalence of drugs being available in their pure forms, the terms "drug checking" or "pill testing" [1] may also be used, although these terms usually refer to testing with a wider variety of techniques covered by drug checking.

A burette is a volumetric measuring glassware which is used in analytical chemistry for the accurate dispensing of a liquid, especially of one of the reagents in a titration. [4] The burette tube carries graduated marks from which the dispensed volume of the liquid can be determined. [5]

Nowadays, most other drugs can be readily measured in blood or plasma using versatile methods such as liquid chromatography–mass spectrometry or gas chromatography–mass spectrometry, which progressively replaced high-performance liquid chromatography. Yet, TDM is not limited to the provision of precise and accurate concentration measurement ...
