Dutrochet's End Osmometer for Demonstrating Osmotic Pressure
Product Code : SCL-BLE-11625
Dutrochet's End Osmometer for Demonstrating Osmotic Pressure (SKU SCL-BLE-11625) is a classroom osmosis set made up of an end osmometer, a beaker and a bottle of sodium chloride (NaCl). Students use it to watch water pass into a salt solution and to relate that movement to the way plant roots take in water. It serves secondary biology and college botany classes. Science Lab Supplies dispatches it from Ambala, India, to schools, colleges, tender contractors and distributors.
Specifications
Three parts make up the Dutrochet set, and each one has its own row in the table: the end osmometer that holds the salt solution, the beaker of water it stands in, and the NaCl used to make the solution. The demonstration it is built for is listed as well.

Applications and Experiments for the Dutrochet Osmometer
The osmometer demonstrates osmotic pressure: salt solution inside it draws water from the beaker, and the rising liquid shows water moving towards the more concentrated side. It supports osmosis lessons in CBSE/NCERT Class 9 and Class 11 biology and plant-physiology practicals in B.Sc. botany.
- Class 9 biology: showing osmosis as the movement of water across a membrane towards a stronger solution.
- Class 11 transport in plants: explaining how root hairs absorb soil water by osmosis.
- Comparing salt solutions of different strengths, each stirred until dissolved with a Glass Stirrer, and noting how far the liquid rises.
- Holding the osmometer upright in the beaker with a clamp on a Laboratory Stand while readings are taken.
In Dutrochet's classic arrangement a membrane at the end of the osmometer separates the salt solution from the water, so mark the starting liquid level before the observation begins.
Standard Scope of Supply
The set comprises the end osmometer, a beaker and a bottle of NaCl. Water and any clamp stand are not included. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Packing, MOQ and Lead Time
Whether you need a single osmometer for the teacher's bench or several for group work, Science Lab Supplies prepares a quotation that sets out packing, delivery time and price for that exact quantity. Stands, beakers or other osmosis apparatus can be quoted on the same document.
Science Lab Supplies holds an Importer-Exporter Code and can ship to buyers in the Philippines, Nepal, Bangladesh, Zambia, Rwanda and South Africa. Requests can come in through the contact page or the enquiry cart, while institutions running a formal purchase can start from the lab tender page.
Frequently Asked Questions
What is Dutrochet's end osmometer used for?
It is used to demonstrate osmotic pressure. A salt solution inside the osmometer takes in water from the surrounding beaker, which shows how plants absorb water through osmosis.
Which solution comes with the set?
A bottle of sodium chloride (NaCl) is included for making the salt solution. The quantity and grade of the salt are confirmed on the quotation together with the batch expiry date.
Who supplies the Dutrochet's End Osmometer for Demonstrating Osmotic Pressure?
Science Lab Supplies supplies it from its base in Ambala, India. Schools, colleges, tender contractors and distributors receive their quotation directly from the Science Lab Supplies sales team.
Can it be quoted for a school science lab tender?
Yes. Send the quantity, delivery location and tender wording, and Science Lab Supplies will return an item-wise quotation for the osmometer set, together with any other biology apparatus on your list.
