Blowpipe Carbon Blocks
Product Code : LSK-CL-10045
Blowpipe Carbon Blocks (SKU LSK-CL-10045) are compressed rectangular carbon blocks made for blowpipe work. A small sample of a salt or mineral is placed in a hollow on the block and heated with a blowpipe flame, and the residue, bead or coating left behind helps identify it. They belong to inorganic qualitative analysis at senior secondary and college level. Ordering is handled by Science Lab Supplies in Ambala, India, which supplies the blocks to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The table below breaks the carbon blocks down fact by fact. Put simply, each piece is compressed carbon pressed into a rectangular block and intended as the sample support in blowpipe work; block size and the number of blocks per pack are confirmed on the quotation rather than fixed here.

Applications and Experiments for the Blowpipe Carbon Blocks
The blocks serve as the heat-resistant support for charcoal-cavity tests. A blowpipe directs the reducing part of a flame onto the sample, and students record whether a metallic bead forms, what colour any incrustation shows and whether the residue glows or fuses, then use that in salt identification.
- Class 12 chemistry: preliminary dry tests for cations in salt analysis, with the flame from a Beck Bunsen burner.
- B.Sc. inorganic chemistry practicals: charcoal-cavity reduction tests.
- Geology and mineralogy labs: blowpipe identification of mineral samples.
- Moving a hot block safely with Stainless Steel Crucible Tongs.
The block, sample and flame become very hot, and some residues give off harmful fumes; work in a ventilated area, use tongs, and let students carry out blowpipe tests only under supervision.
Standard Scope of Supply
The Blowpipe Carbon Blocks are supplied as compressed rectangular carbon blocks; the number of blocks per pack is confirmed on the quotation. The blowpipe, burner and crucible tongs are not included and can be added to the same order so the dry-test station is priced as one list.
Packing, MOQ and Lead Time
Whether you need a few blocks for a teacher's demonstration or enough for every student in a salt-analysis batch, ask for a quotation; it will set out packing, delivery time and price for that quantity. Other chemistry lab instruments from the same supplier can travel on one order.
Because it holds an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. Name the block quantity for your salt-analysis batch in a message on the contact page, or save the blocks with the blowpipe in the enquiry cart; colleges buying through a tender should start from the lab tender page.
Frequently Asked Questions
Why is carbon used for blowpipe work?
Carbon withstands the flame and helps reduce metal compounds, so many salts leave a characteristic metal bead or coloured coating on the block that points to the metal present in the sample.
How many blocks come in a pack?
The pack quantity and block size are stated on the quotation. Send your required number through the contact page and the blocks will be quoted to suit your class size and the number of salts each student tests.
Who supplies the Blowpipe Carbon Blocks?
Science Lab Supplies in Ambala, India supplies these blocks as a dry-test consumable, and the same quotation can carry blowpipes, burners, tongs and other apparatus for qualitative salt analysis.
Do the blocks come with a blowpipe?
No. The blocks are supplied on their own. A plated brass blowpipe and a gas burner or spirit lamp are separate items and can be quoted together with the blocks for a complete blowpipe station.
