Parchment Paper (Semi Permeable) Manufacturer,Supplier and Exporter in India

Parchment Paper (Semi Permeable) (Product Code: SCL310/055) is a semi-permeable membrane paper used for osmosis testing in school and college biology practicals. Supplied as a book of 100 leaves, it lets water pass while holding back larger dissolved molecules such as sugar, so a sheet tied over a thistle funnel makes osmosis visible. A key consumable for any osmosis experiment kit in a school lab, it is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Key Details

What Is the Semi-Permeable Parchment Paper Used For?

The classic set-up uses a thistle funnel: a piece of parchment is tied tightly over the wide mouth, the funnel is filled with concentrated sugar solution, and it is inverted into a beaker of water. Over the lesson, the liquid level in the stem rises as water moves through the membrane into the sugar solution. Marking the starting level and recording the rise at intervals turns the demonstration into a measured practical, and swapping the solutions shows that water always moves towards the more concentrated side.

Moisten the sheet in water for a short time before use so it becomes pliable and does not tear when tied. Stretch it evenly, tie it with thread in two or three turns and check for leaks before starting. As part of the cell biology equipment in a school lab, the same paper helps students connect the demonstration to what happens at cell membranes in root hairs, red blood cells and plant tissue.

Supplier

This membrane paper is supplied by Jain Scientific Equipments Private Limited, the Ambala, Haryana company that trades as ScienceLab and provides consumables for biology, chemistry and physics teaching across India and international markets. Teachers can add the funnels, beakers and sugar needed for the same practical to one enquiry and receive a single quotation. Visit the company profile for details.

Frequently Asked Questions

How many leaves are in a book of Parchment Paper (Semi Permeable)?
Each book of Parchment Paper (Semi Permeable) contains 100 leaves. That is enough for many osmosis demonstrations or for a class working in small groups, since each set-up needs only one piece tied over the funnel mouth.

What size are the parchment paper leaves?
The leaf size of this parchment paper is not stated in our current listing. If you need the sheets to cover a particular funnel or tube, ask us through the contact page and we will confirm the dimensions before you order.

Can kitchen baking paper replace semi-permeable parchment paper?
Kitchen baking paper is not a reliable replacement for this semi-permeable parchment paper. Baking papers are often coated and are not intended to act as an osmosis membrane, so the rise in the funnel stem may be slow or absent.

Can a sheet of parchment paper be reused?
For dependable results, use a fresh piece of parchment paper for each osmosis experiment. A used sheet may be stretched, torn at the tie line or carry sugar residue, and any of these can make the result misleading.

Which solution gives the clearest result with the parchment paper?
A concentrated sucrose solution behind the parchment paper, with plain water outside, usually gives a clearly visible rise in the funnel stem within a single lesson. Mark the starting level so students can measure the change.

Who supplies the Parchment Paper (Semi Permeable)?
Parchment Paper (Semi Permeable), code SCL310/055, is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India. The company provides biology consumables to schools, colleges, dealers and importers in India and international markets.

How should the parchment paper book be stored?
Keep the parchment paper book flat, dry and closed, away from humidity and heat, so the leaves do not cockle or stick together. Take out only the sheets needed for the day's practical.
