Osmotic Pressure Apparatus
Osmotic Pressure Apparatus (Product Code: SCL222/034) is a glass demonstration set used to show osmosis and osmotic pressure at elementary levels in school biology classes. A semipermeable membrane seals the open mouth of a thistle funnel fitted with an indicator tube, the funnel stands in a reservoir, and a dropping pipette is supplied with the set. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Osmotic Pressure Apparatus Used For?
It is used to make the movement of water across a membrane visible to a whole class. The funnel is filled with a concentrated sugar solution, the membrane is secured over its mouth, and the funnel is placed mouth-down in a reservoir of water with the indicator tube held upright. Water moves through the membrane into the more concentrated solution and pushes the column up the tube; marking the level at intervals turns the demonstration into a simple set of readings. The dropping pipette is used to adjust the starting level precisely.
Tie the membrane tightly and check for leaks before starting, clamp the tube vertically and add a little food colour to the sugar solution so the column is easy to see from the back of the room. As an osmosis experiment kit for school classes, the set suits the secondary years in which osmosis is first taught.
OEM Manufacturer
Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM of this apparatus and makes it at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges, dealers and importers therefore deal directly with the maker, and can ask us about spare membranes or replacement glass parts. Institutions setting ScienceLab up as a vendor can use GSTIN 06AAECJ8618A1ZT and LEI 3358004HRD1JIVXKYX49. Visit the company profile for more.

Items used with the osmotic pressure apparatus during the demonstration:
- Parchment Paper (Semi Permeable) — spare membrane material for repeat runs.
- Sucrose — for preparing the concentrated solution inside the funnel.
- Beaker — can serve as the water reservoir.
- Retort Stand — holds the indicator tube upright during the run.
- Visualising Osmosis & Diffusion Investigation — a complementary activity on the same topic.

Frequently Asked Questions
What is included with the Osmotic Pressure Apparatus?
The Osmotic Pressure Apparatus consists of a glass thistle funnel with indicator tube and a semipermeable membrane, supplied complete with a dropping pipette. Confirm through the contact page whether a reservoir vessel is included; a beaker can serve instead.
Which solution goes inside the Osmotic Pressure Apparatus funnel?
A concentrated sugar solution is the usual choice inside the Osmotic Pressure Apparatus for school demonstrations, with plain water in the reservoir, so water moves through the membrane and raises the column in the indicator tube.
How quickly does the level rise?
The rise in the Osmotic Pressure Apparatus depends on solution concentration, temperature and the membrane. Setting it up at the start of a lesson and reading the level at regular intervals usually gives students a clear result.
Can the membrane of the Osmotic Pressure Apparatus be replaced?
Yes. The membrane of the Osmotic Pressure Apparatus can be replaced; semipermeable parchment paper is available separately, and spare parts for the set can be requested directly from ScienceLab as the manufacturer.
Is the Osmotic Pressure Apparatus suitable for quantitative measurement?
The Osmotic Pressure Apparatus is designed for exploring osmosis and osmotic pressure at elementary levels. For higher-level quantitative work, discuss your requirement with us before ordering so that suitable apparatus can be suggested.
Who manufactures the Osmotic Pressure Apparatus?
The Osmotic Pressure Apparatus is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India, and is supplied factory-direct to schools, colleges, dealers and importers.
What should a quotation request for the Osmotic Pressure Apparatus include?
A quotation request for the Osmotic Pressure Apparatus should give the quantity, whether you need spare membranes or sucrose, and the delivery location. Supply is available across India and international markets.
