Dropping Funnel With Tap 50ml

A dropping funnel with a tap (also called a stopcock) is a specialized piece of laboratory glassware used for the precise transfer of liquids in controlled drops or small volumes. Here’s a breakdown of its key features and functionalities:

• Capacity: This specific model has a capacity of 50ml, allowing you to transfer up to 50 milliliters of liquid.
• Material: Typically made of borosilicate glass, a heat-resistant and chemically resistant glass suitable for laboratory use.
• Components:
  • Funnel body: A bulb-shaped container to hold the liquid.
  • Stem: A narrow tube connecting the funnel body to the tap.
  • Tap (Stopcock): A valve mechanism that allows for controlled release of the liquid in drops or small streams. The tap usually has a key or knob for opening and closing.
• Function:
  1. The liquid is poured into the funnel body.
  2. The tap is closed to prevent any dripping.
  3. By opening the tap slightly, the user can control the flow of the liquid, allowing for precise addition drop-by-drop or in small, controlled streams.

Applications:

• Titration experiments: Adding precise amounts of a titrant solution drop-wise during a titration process.
• Adding indicators or reagents: Controlled addition of small quantities of indicators or reagents to a reaction mixture.
• Setting up experiments: Transferring specific volumes of liquids for various lab procedures.
• Separating liquids: In some cases, it can be used to separate immiscible liquids (liquids that don’t mix) by carefully controlling the flow of the lower layer through the tap.
