Glass Centrifuge Tube

Product Code : SCL-LG-11988

The Glass Centrifuge Tube is a laboratory vessel used to hold liquid samples during centrifugation, where centrifugal force separates components according to differences in density and sedimentation behaviour. It is intended for chemistry, clinical, analytical, educational, and research laboratories requiring clear sample observation and controlled separation procedures.

Product Description

A Glass Centrifuge Tube holds a laboratory sample while a compatible centrifuge rotates it at a specified speed or relative centrifugal force. During centrifugation, denser particles or phases move toward the lower part of the tube, allowing separated fractions, supernatants, sediments, or pellets to be observed and processed according to the laboratory method.

This product has glass construction, but its exact glass grade, capacity, bottom shape, graduations, closure type, dimensions, and maximum permitted RCF are. These parameters must be verified before centrifugation. Buyers can explore related laboratory glassware for complementary laboratory requirements.

Key Features

• Designed for centrifugation: Holds suitable liquid samples during centrifugal separation procedures.
• Transparent glass body: Supports direct observation of sample layers, sediment, pellets, and supernatant.
• Laboratory sample handling: Suitable for compatible separation, preparation, and analytical workflows.
• Capacity: Exact nominal volume is .
• Glass specification: Exact composition and grade are.
• RCF compatibility: Maximum permitted relative centrifugal force must be confirmed before operation.
• Educational value: Supports supervised demonstrations of centrifugation, density-based separation, and sedimentation.

How to Use the Glass Centrifuge Tube

1. Inspect the tube for cracks, chips, scratches, or other visible damage.
2. Confirm that its dimensions and maximum RCF are compatible with the centrifuge rotor and adapter.
3. Add the required sample without exceeding the verified filling limit.
4. Prepare an opposing tube of equal mass to balance the centrifuge correctly.
5. Place tubes symmetrically in the rotor.
6. Set the speed, RCF, temperature, and time according to the approved laboratory procedure and verified tube rating.
7. After centrifugation stops completely, remove the tube carefully and process the separated fractions as required.

Safety note: Never centrifuge cracked or damaged glassware. Do not exceed the verified RCF rating, and always balance opposing tubes correctly before starting the centrifuge.

Care & Maintenance

• Clean promptly using a method compatible with the sample and confirmed glass composition.
• Inspect before every centrifugation cycle for cracks, scratches, chips, or stress damage.
• Avoid sudden temperature changes and mechanical impact.
• Store upright in a suitable rack to prevent rolling and breakage.

Frequently Asked Questions

What is a Glass Centrifuge Tube used for?

A Glass Centrifuge Tube holds liquid samples during centrifugation so components can be separated according to differences in density and sedimentation behaviour.

What is the capacity of this Glass Centrifuge Tube?

The exact nominal capacity of this Science Lab Supplies product is . Capacity should be verified before ordering or selecting a compatible rotor.

What type of glass is the centrifuge tube made from?

The product is identified as a glass centrifuge tube, but its exact glass composition and grade are .

Can any glass centrifuge tube be used at any centrifuge speed?

No. Every tube must be operated within its verified RCF limit and with a compatible rotor or adapter. Never assume a safe speed without product-specific data.

Why must centrifuge tubes be balanced?

Opposing centrifuge positions should contain tubes of equal mass to reduce vibration, rotor imbalance, equipment stress, and the risk of tube failure.

Can Glass Centrifuge Tubes be used in schools and colleges?

Yes, they can support supervised demonstrations and laboratory practicals involving centrifugation, sedimentation, and density-based separation, provided suitable equipment and safety procedures are used.
