Hollow Glass Prism
Product Code : LSK-LAO-11137
Hollow Glass Prism (SKU LSK-LAO-11137) is an optics prism whose sides are plane plates of ordinary plate glass, offered in 25 mm, 38 mm and 50 mm sizes for spectrometer work. Because it is hollow, it is used with a clear liquid inside to study refraction by liquids in senior school and college physics labs. Science Lab Supplies manufactures the prism at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and sells it directly to schools, colleges, tender contractors and distributors.

Applications and Experiments for the Hollow Glass Prism
Filled with water or another transparent liquid, the hollow prism lets students measure how strongly that liquid bends light, using either a spectrometer or the pin method on a drawing board. It supports refraction and dispersion work in Class 12 and B.Sc. optics, and is useful optics lab equipment for schools and colleges.
- B.Sc. practical: finding the refractive index of a liquid from the angle of minimum deviation on a Laboratory Spectrometer.
- Class 12 physics: tracing the path of light through a liquid prism and plotting angle of deviation against angle of incidence, locating rays with an Optics Experiment Parallax Pin.
- Comparing the refractive index of water with that of a glass prism of the same size.
- Showing a spectrum from white light passing through a liquid-filled prism.
Fill and empty the prism over a tray, wipe the plates dry after each class, and return it to its velvet-lined case.
Standard Scope of Supply
Each Hollow Glass Prism is supplied in the size ordered, 25 mm, 38 mm or 50 mm, inside a velvet-lined case. Liquids for filling, a spectrometer and drawing-board accessories are not included; please state the size and quantity you need so the quotation can list every item to be packed.
Packing, MOQ and Lead Time
You can request a quotation for one prism, a mix of the three sizes or a full set for every spectrometer in the lab. As a science apparatus manufacturer in India, Science Lab Supplies confirms the packing, delivery time and price for that exact order, and solid prisms or spectrometers can join the same quotation.
With its Importer-Exporter Code, Science Lab Supplies can ship to buyers in Uganda, the UAE, Saudi Arabia, Oman, the Philippines and Nepal. Write to us from the contact page, place items in the enquiry cart, or check the lab tender page for tender support.
Frequently Asked Questions
What is a hollow glass prism used for?
It is used to measure the refractive index of liquids. The prism is filled with the liquid and placed on a spectrometer table, or on paper for ray tracing, and the deviation of light through it is measured.
Which sizes are available?
Three sizes are offered: 25 x 25 x 25 mm, 38 x 38 x 38 mm and 50 x 50 x 50 mm. Choose the size that suits your spectrometer prism table or the ray-tracing work planned for the class.
How should the prism be stored?
Empty and dry the prism after use, then keep it in the velvet-lined case it is supplied in. This protects the plate glass sides from scratches and chips between practical sessions.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. This prism is produced in its own Saha, Ambala workshop, so prices, sizes and packing are agreed with the maker directly rather than through a reseller.
