Glass Centrifuge Tube

Product Code : SCL-LG-11988

Glass Centrifuge Tube (SKU SCL-LG-11988) is a clear glass vessel that holds a liquid sample in a centrifuge so that denser particles or phases are driven to the bottom and can be separated from the liquid above. Chemistry, biology, analytical and research laboratories use it for sedimentation and sample preparation. Science Lab Supplies ships this tube from its base in Ambala, India to schools, colleges, research laboratories, tender contractors and distributors.

Specifications

The tube is made of transparent glass, so sediment, pellets, layers and supernatant are visible without opening the sample. Capacity, glass grade, bottom shape, graduations, closure and maximum relative centrifugal force are not fixed in the listing and are confirmed on the quotation for the tube offered.

Applications and Experiments for the Glass Centrifuge Tube

These tubes are used whenever a suspension has to be split quickly into solid and liquid. Spinning concentrates the precipitate or cells at the tip, and the clear supernatant is then drawn off for further tests. Typical users are chemistry practical classes, life-science courses and laboratories preparing samples for analysis.

• B.Sc. chemistry semi-micro qualitative analysis: separating precipitates from solution.
• B.Sc. biochemistry and microbiology: collecting pellets and sediments.
• Medical laboratory technology training: practising sample centrifugation technique.
• Demonstrating centrifugal force and density-based separation.

Always load opposite rotor positions with tubes of equal mass, stay within the rated speed, and never spin a chipped or cracked tube.

Standard Scope of Supply

Each unit is one Glass Centrifuge Tube. Caps or stoppers, the centrifuge, rotor, adapters, racks and pipettes are not included; tubes are normally ordered in even numbers so that the rotor can be balanced, and the quantity you enquire for can reflect that.

Packing, MOQ and Lead Time

Tubes can be quoted in any quantity, from a few spares to a full stock for a practical class. The quotation you receive lists packing, delivery time and price for the number requested, and racks, pipettes or other chemistry lab equipment in India can be included alongside.

Because it holds an Importer-Exporter Code as a registered exporter, Science Lab Supplies is able to ship to buyers in Egypt, Iraq, Nigeria, Kenya, Ghana and Ethiopia. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). For prices and quantities, use the contact page or add the tube to the enquiry cart; institutional buyers will find guidance on the lab tender page.

Frequently Asked Questions

What is a glass centrifuge tube used for?
It holds a liquid sample while a centrifuge spins it, so particles or heavier phases collect at the bottom. The separated sediment and supernatant can then be observed and handled separately.

Can the tube be run at any centrifuge speed?
No. Every tube has a maximum relative centrifugal force and must fit the rotor or adapter used. Confirm the rating for the tube on your quotation and never exceed it.

Why do centrifuge tubes have to be balanced?
Opposite positions must carry tubes of equal mass. An unbalanced load causes vibration, strains the rotor and increases the chance of a glass tube breaking during the run.

Who supplies the Glass Centrifuge Tube?
Science Lab Supplies supplies it from Ambala, India to teaching and research laboratories. Distributors and tender contractors can request tubes in bulk together with related glassware on a single quotation.

Related Sample Handling Glassware

Centrifugation sits in the middle of a sample workflow: material is prepared in tubes, measured in small volumes and, after spinning, the supernatant is drawn off. The four items below support those steps and are often ordered together for the same practical.

• Test Tubes — for preparing and reacting samples before centrifuging.
• Glass Dropper Pipette 6 — draws off supernatant from above the sediment.
• Pipette Graduated 0.1ml — measures small reagent volumes into the tube.
• Borosilicate Beaker — holds wash liquids and collected fractions.
