Answer:
b. Transfer pipets; more accurate; measuring pipets.
Explanation:
Transfer pipets can be defined as an ungraduated or graduated disposable plastic instrument which are typically used in science laboratories to transfer or deliver liquids that are small in volume (microliters) . Also, they are generally being referred to as chemical
droppers, teat pipets, eye droppers, pasteur pipets, or droppers. It is made up of an ultra-clear long, slender tube with low density polyethylene (LDPE) and an integral molded bulb. The molded bulb allows a fixed volume of the desired liquid to be dispensed (transfered) or aspirated through compression and relaxation.
Hence, transfer pipets are calibrated to deliver one fixed volume and are more accurate than measuring pipets because of its long, slender tube which limits errors.
Transfer pipets are measurement pipets since they are calibrated to provide a specific volume.
Transfer pipets have been ungraduated as well as graded disposable plastic instruments that were already commonly used during research labs to transmit as well as distribute small-volume liquids.
Combining compression as well as relaxation, the molded bulb permits a set volume of such necessary fluid material to be administered as well as inhaled.
Thus the response above is correct.
