Compass
Product Code : SCL-BLE-11641
Compass (SKU SCL-BLE-11641) is a 90 mm round magnetic compass for general laboratory use, with a balanced needle that swings freely to line up with the Earth’s magnetic field and a dial marked with the cardinal points. It serves field-study, ecology and geography lessons in school biology labs as well as basic magnetism work. Science Lab Supplies sends it out from Ambala, India, to schools, colleges, tender contractors and science distributors that need direction-finding instruments for students.
Specifications
The table sets out each specification of this 90 mm compass. In short, a well-balanced magnetised needle is mounted in an aluminium case with a glass top, the round silver-coloured body combines plastic and stainless steel, and the dial shows the four cardinal points for quick orientation in the field or on the bench.

Applications and Experiments for the Compass
The compass finds magnetic north so students can orient maps, set out transects and record which way a habitat faces during fieldwork. It also supports simple magnetism lessons, which makes it a practical item of school biology lab equipment in India for both outdoor surveys and indoor bench demonstrations.
- Class 6–8 science and geography: finding the cardinal directions and orienting a simple map of the school grounds.
- Class 9–12 ecology practicals: laying a transect line in a known direction and measuring it with the Tape Measure.
- Insect and habitat surveys with the Entomological Network, noting the direction in which each sample was taken.
- Introductory magnetism: showing that a freely pivoted magnetised needle settles along the Earth’s magnetic field.
Standard Scope of Supply
Each order line covers one compass: the 90 mm round body with its balanced magnetised needle and cardinal-point dial, mounted in the aluminium case with a glass top. Maps, tape measures and field notebooks are not included, although a tape measure and other field-study items can be quoted with it.
Packing, MOQ and Lead Time
A quotation can be prepared for a single compass or for a class set that gives every fieldwork group its own instrument. Science Lab Supplies lists the packing, delivery time and price for the requested quantity, and nets, magnifiers or thermometers for the same field trip can share that quotation.
With an Importer-Exporter Code in place, Science Lab Supplies is able to ship to buyers in Ethiopia, Tanzania, Uganda, the UAE, Saudi Arabia and Oman. For a compass price, send your quantity through the contact page, drop the item into the enquiry cart, or check the lab tender page when the purchase runs through a formal bid.
Frequently Asked Questions
What is this compass used for in a biology lab?
It shows direction relative to the Earth’s magnetic poles, so students can orient field maps, lay out transects in a known direction and record which way a slope or habitat faces during ecology and environmental-science practicals.
How large is the compass and what is the case made of?
The round body measures 90 mm across. Its balanced needle sits in an aluminium case with a glass top; the case is of aluminium ply type, 18 mm, with glass on both sides, and the materials include plastic and stainless steel.
Does the dial show degrees?
The dial shows the cardinal points, which is enough for orienting maps and transects. Where readings in degrees are needed, the 45 mm Pocket Compass in the related list below is marked in degrees with N and S indications.
Who supplies the Compass?
Science Lab Supplies supplies this compass from Ambala, India. Schools, colleges, tender contractors and distributors can order it directly, either on its own or together with other field-study and biology items on one quotation.
