Jumbo Test Tubes Manufacturer,Supplier and Exporter in India

Product Code : EL-WS-11883

The Jumbo Test Tubes are large-format laboratory test tubes used to hold, mix, observe, and transfer larger sample quantities during supervised chemistry, biology, STEM, and general science practicals. They are suitable for schools, colleges, science laboratories, distributors, and institutional procurement teams requiring classroom labware.

Product Description

Jumbo Test Tubes from School Equipments India are intended for laboratory demonstrations and practical activities where a standard small test tube may not provide enough working volume. Their larger size can support visible classroom demonstrations, sample comparison, solution mixing, sediment observation, colour-change reactions, and specimen display. Exact capacity, diameter, length, material, wall thickness, rim type, bottom shape, and pack size must be confirmed from the final supplied product.

These test tubes support hands-on learning in chemistry and biology because students can observe changes clearly inside a vertical transparent vessel. They should not be described as borosilicate, autoclavable, heat-resistant, graduated, centrifuge-safe, sterile, or flame-heatable unless the supplied product documentation confirms those specifications.

Key Features

• Jumbo laboratory format: supports larger-volume classroom demonstrations compared with regular small test tubes [confirm capacity].
• Observation-friendly design: useful for colour change, sedimentation, liquid layers, specimen viewing, and reaction comparison.
• School lab utility: suitable for chemistry, biology, environmental science, STEM, and general science activities.
• Reusable labware option: may support repeated classroom use if the supplied material and cleaning method allow reuse [confirm].
• Rack-compatible use: can be stored upright in a suitable test tube rack if the diameter matches the rack holes.
• Heat-use caution: heating suitability must be confirmed before using with burners, water baths, or hot liquids.
• Specifications to confirm: material, capacity, size, rim, wall thickness, pack quantity, and safety limits must be verified.

How to Use the Jumbo Test Tubes

1. Inspect each test tube for cracks, chips, scratches, contamination, or damaged rims.
2. Confirm the test tube material is suitable for the liquid, sample, or activity.
3. Place the test tube upright in a compatible rack before adding liquids or samples.
4. Add the required material slowly without exceeding the safe working volume.
5. Mix gently by swirling only if the teacher confirms the tube and contents are suitable.
6. Use a proper test tube holder or clamp if handling hot contents is approved.
7. Do not heat the test tube unless heat resistance is confirmed by documentation.
8. Clean, dry, and store the test tube after the practical session.

Safety note: Use only under teacher or laboratory-supervisor control. Do not heat unknown glass, point a test tube toward anyone, seal reactive mixtures, use cracked tubes, or handle chemicals without appropriate PPE.

Care & Maintenance

• Wash test tubes after use according to the chemicals or samples handled.
• Dry fully before storage to prevent residue, odour, staining, or contamination.
• Store upright in a rack or protected carton to avoid impact and breakage.
• Replace chipped, cracked, cloudy, contaminated, deformed, or poorly fitting tubes before reuse.
