A lab tube is a type of laboratory equipment used to measure, store, and transfer liquids. The four solutions for the term lab tube are pipet (5 letters), PIPETTE (7 letters), burette (7 letters), and VIAL (4 letters). A pipet is a thin tube with a bulb at one end used to draw liquid into the tube and then dispense it in measured amounts. A PIPETTE is similar to a pipet but is usually made of plastic and has a plunger that can be used to draw liquid into the tube and then dispense it. A burette is a long, graduated tube with a stopcock at one end used to measure and dispense precise amounts of liquid. Finally, a VIAL is a small container with a lid or stopper used to store and transport liquids.
