Which lab tool is a plastic qualitative pipet used to dispense chemicals and is often used in place of a dropper?

• A. Transfer Pipet (Beral Pipet)
• B. Test Tube Rack
• C. Hot Plate
• D. Swab

Answer: (A)

Transferring small amounts of liquid cleanly and quickly is the main idea here. A plastic qualitative pipet, also known as a transfer pipet or Beral pipet, is designed to pick up and dispense liquids in a simple, controllable way. It’s disposable and doesn’t have precise measurement marks, which makes it ideal for qualitative transfers and for substituting a dropper when exact volume isn’t needed. This keeps things convenient and minimizes cross-contamination in routine tasks. The other items serve different purposes: a test tube rack simply holds tubes, a hot plate provides heat, and a swab is used to collect samples from surfaces.
