The can be used to calculate the density of an object if its mass is known. Glassware used in a chemistry laboratory is special. The contents of the dish are exposed to air and light, but the air is exchanged by diffusion, preventing contamination of the contents by microorganisms. Additionally, certain chemicals may weaken the glass. Add 2-3 drops of phenolphthalein indicator to the solution in the flask and titrate the solution to a faint pink endpoint using the 1 M NaOH in the buret. In Feb 2011, we took steps to come in Medical and Laboratory supply field after finding unregulated priced product in the market. Flasks are divided into 6 types, depending on the culture scale and the cap type. This is an example of a T bore stopcock. Remove the hose and stopper the flask tightly. NMR tubes are thin glass tubes that are used to hold samples used for nuclear magnetic resonance spectroscopy. Product Results. No lab would be complete without beakers. With the separating funnel suspended above a conical fask (erlenmeyer flask) and the stopper removed, open the stopcock and allow the more dense aqueous layer to flow into the conical flask.
