Question

Common laboratory glassware is classified as non-volumetric or volumetric glassware, which can be intended "to deliver" (TD) or "to contain" (TC). Based on your understanding, (a) For the glassware stated in Table 1 of your lab manual, classify the glassware as non-volumetric or volumetric glassware. (b) For those glassware classified as volumetric glassware, which of them are TD or TC glassware?
