Welding Filter Lens
Product Code : LSK-CL-10274
Welding Filter Lens (SKU LSK-CL-10274) is a pack of ten Shade 9 filter lenses, the shade recommended for safe viewing of burning magnesium and similar intensely bright reactions in the chemistry lab. In combustion demonstrations, a filter lets the white flame be observed through a dark Shade 9 filter rather than with the naked eye. Science Lab Supplies sends the packs out from Ambala, India against quotations from schools, colleges, training institutes, tender contractors and distributors.
Specifications
Shade rating and pack size of these filters appear as separate rows below. In short, each pack holds ten welding filter lenses rated Shade 9, the shade recommended for safe viewing of burning magnesium and other very bright reactions; a shade number describes how strongly a filter darkens the light passing through it.

Applications and Experiments for the Welding Filter Lens
Burning magnesium gives off a dazzling white light that is uncomfortable and potentially harmful to look at directly. Holding a Shade 9 filter between the eye and the flame lets students watch the reaction and the white ash forming, which keeps attention on the chemistry rather than on the glare.
- NCERT Class 10 science, Chemical Reactions and Equations: burning magnesium ribbon in air, lit in a Beck Bunsen flame, to form magnesium oxide.
- Middle-school science: observing combustion and the signs of a chemical change.
- Class 11 chemistry: reactions of alkaline earth metals with oxygen.
Burning magnesium is very hot and bright. Run the demonstration only under teacher supervision, hold the ribbon with Stainless Steel Crucible Tongs, give students eye protection such as Safety Goggles, Polycarbonate, 12 pcs, and keep them at a distance with the filter in front of their eyes throughout.
Standard Scope of Supply
One pack contains 10 Shade 9 welding filter lenses. Magnesium ribbon, tongs, a burner and safety glasses are not included; they are available as separate items and can be quoted with the filters for a complete combustion demonstration kit.
Packing, MOQ and Lead Time
Buy one pack for a single class or several packs for a school or district. Your quotation will give packing, delivery time and price for the number of packs ordered, and other chemistry lab equipment can be added to it.
Because Science Lab Supplies is a registered exporter holding an Importer-Exporter Code, it can ship to buyers in Nigeria, Kenya, Ghana, Ethiopia, Tanzania and Uganda.

Frequently Asked Questions
How many filters are in a pack?
Each pack contains 10 Welding Filter Lenses, all Shade 9, enough to share among a small class or several groups during a demonstration.
Why use a welding filter in a chemistry lab?
Burning magnesium produces an intense white light. A Shade 9 welding filter is recommended for viewing it, so students can watch the reaction without staring into the glare.
Who supplies the Welding Filter Lens?
Packs are quoted and shipped by Science Lab Supplies from Ambala, India, to schools, colleges, contractors and distributors, and magnesium or handling tools can be priced alongside them.
Do the filters replace safety glasses?
No. The filters are for viewing the flame. Students should still wear safety glasses and follow the teacher's instructions during any combustion demonstration.
Related Combustion and Eye Protection Items
These items are used alongside the filters when burning magnesium or other substances in class: the metal itself and its oxide, spoons for holding samples in a flame or gas jar, tongs for hot material, and safety glasses or a welding shield for eye protection. All can share one quotation.
