Chemistry Hardware Assortment

Quick Answer: The chemistry hardware assortment is a set of metal and plastic support tools for holding apparatus during practicals. The listing photo shows a tripod, a retort stand base and rod, a ring with clamp, clamps and a boss head, beaker and crucible tongs, a pipe-clay triangle, a test-tube holder, a wire gauze and a test-tube rack.

The Supporting Hardware Behind Every Practical

Glassware gets the attention, but almost every chemistry practical also needs something to hold, lift or support it. This assortment gathers those pieces into one order. The photo shows a heavy base plate with a stand rod, a black tripod, a support ring with its own screw clamp, a three-finger clamp on a boss head, a separate boss head, coated beaker tongs, crucible tongs, a wire test-tube holder, a pipe-clay triangle and a square wire gauze with a ceramic centre. A white plastic test-tube rack and a small screw clamp complete the set.

Each item has a specific job. The tripod and gauze spread the heat under a beaker; the pipe-clay triangle holds a crucible directly in the heat; the ring on the stand supports a funnel or a gauze at an adjustable height; the clamp holds a flask, burette or condenser; and the tongs move hot vessels safely. Setting these up correctly is itself a practical skill that assessments expect students to show.

The metal pieces suit gas and electric burners alike, but the plastic rack must stay away from heat. For glassware to go with the hardware, see the chemistry labware kit; individual stands and clamps are also available in the metalware range.

Specifications

Applications

• Heating a beaker of water on a tripod and gauze for dissolving and evaporation practicals
• Heating a crucible in a pipe-clay triangle, as when finding the formula of magnesium oxide
• Clamping a burette or condenser to the retort stand during titration or distillation
• Filtration with a funnel supported in the ring above a beaker

Care & Handling

• Tighten the boss heads and clamps from the chemistry hardware assortment only enough to hold; over-tightening cracks glassware.
• Let tripods, gauzes and triangles cool before touching them, since they look the same hot or cold.
• Replace gauzes with torn wire or a crumbling centre, and pipe-clay triangles with cracked sleeves.
• Keep the plastic test-tube rack away from burners and hot tripods.

Why Choose LabEquip

Schools equipping a new chemistry room, or replacing a scattered collection of worn stands and clamps, buy the hardware assortment as a single set. It is listed with LabEquip’s chemistry lab equipment, and orders covering several benches can be placed through the contact page.

Frequently Asked Questions

What is the pipe-clay triangle used for?

It rests on a tripod or ring and holds a crucible directly in the heat. The ceramic-covered wires stay rigid at high temperature and do not stick to the crucible.

Why does the wire gauze have a ceramic centre?

The ceramic centre spreads the heat over a wider area of the vessel’s base, so a beaker warms evenly instead of at one hot spot, which reduces the risk of cracking.

What is the difference between beaker tongs and crucible tongs?

Beaker tongs have wide, curved and often coated jaws that grip the side of a beaker. Crucible tongs have narrow, bowed tips for lifting a small crucible or its lid out of a pipe-clay triangle.

How should a boss head and clamp be set up?

Fix the boss head to the stand rod with its open side facing upward, fit the clamp into it, and position the apparatus over the stand base so that the stand cannot tip.

Can the hardware be used with electric burners?

The metal tripod, gauze and ring can be used over electric burners just as over gas ones, as long as they sit stably. The plastic rack must be kept away from any heat source.

Which items are needed for a titration?

The retort stand base and rod with a clamp and boss head to hold the burette vertically. A white tile under the flask helps show the colour change, though it is not part of this set.
