Salt Bridge
Product Code : EL-GPA-11631
The Salt Bridge is an electrochemistry apparatus used to complete reversible cell circuits and support EMF measurement experiments. It is suitable for schools, colleges, chemistry laboratories, physics laboratories, science teachers, laboratory suppliers, distributors, and educational procurement buyers teaching electrolysis, electrochemical cells, and current-flow conditions.
Product Description
The Salt Bridge from School Equipments India is listed under Chemistry / Gas Preparation & Analysis with Product Code EL-GPA-11631. The product listing states that this apparatus provides a more effective method of making reversible cells than wet paper or agar gel methods.
The bridge comprises an inverted U tube with its ends closed by sintered discs. It is intended for experiments involving the measurement of cell EMF under forward, zero, and reverse current flow conditions. The confirmed 13 mm arm diameter, 100 mm height, and 80 mm overall width make it suitable for structured classroom electrochemistry demonstrations.
Key Features

How to Use the Salt Bridge
- Confirm the approved electrochemistry method, electrodes, electrolyte solutions, and measuring instrument before use.
- Inspect the salt bridge for cracks, blocked sintered discs, contamination, or leakage.
- Prepare the half-cell beakers according to the laboratory procedure.
- Place each end of the inverted U tube into the appropriate half-cell solution.
- Connect the electrodes to a voltmeter, galvanometer, or approved low-voltage measuring circuit.
- Observe the EMF reading under forward, zero, or reverse current flow conditions as directed.
- Do not allow the bridge to dry out or become blocked during the experiment.
- After use, rinse, drain, and store the apparatus according to the laboratory method.
Safety note: Use the Salt Bridge only in low-voltage educational electrochemistry experiments. Do not connect the apparatus to mains electricity. Wear goggles and gloves when handling electrolytes, and follow the safety instructions for all solutions used.
Care & Maintenance
- Rinse the bridge after use to remove electrolyte residue from the tube and sintered discs.
- Prevent the sintered disc ends from drying with incompatible deposits or blocked salts.
- Store the bridge safely to avoid impact damage to the U tube and disc ends.
- Remove cracked, blocked, contaminated, or leaking salt bridges from service.
