Glass Conical Centrifuge Tubes Non Calliberated, BORO 3.3

Description

Glass Conical Centrifuge Tubes, BORO 3.3 are designed for routine laboratory centrifugation, sample separation, sedimentation and liquid handling where a clear, chemically resistant glass tube is required. The conical tube shape helps concentrate separated material toward the lower end of the tube, making it practical for observing sediment, precipitates or heavier sample fractions after centrifugation. This makes the tube suitable for school science laboratories, university teaching labs, research benches, quality control areas and general laboratory sample preparation.

Manufactured from BORO 3.3 borosilicate glass, these conical centrifuge tubes provide the clarity, durability and thermal stability expected from laboratory glassware. BORO 3.3 is widely used for scientific glassware because it has low thermal expansion and good resistance to chemical exposure under suitable laboratory conditions. ISO 3585 specifies the properties of borosilicate glass 3.3 used for laboratory glass construction, while ASTM E438 is commonly referenced for glass used in laboratory apparatus. These standards should be used as material reference wording unless the product has a specific compliance certificate.

The transparent glass body allows users to visually inspect liquid level, sample clarity, phase separation and sediment formation before and after centrifugation. This is useful in practical teaching work, sample preparation, suspension settling, precipitate collection and routine separation tasks. The conical profile also helps improve visibility at the tube base, supporting clearer observation of collected material compared with flat-bottom formats.

These glass conical centrifuge tubes are suitable for use with compatible centrifuge rotors, tube holders or manual centrifuge systems where the correct tube size and support are confirmed before operation. Users should always balance tubes correctly, inspect glassware for chips or cracks before use and follow the centrifuge manufacturer’s operating instructions. As with all centrifuge glassware, tube compatibility, sample suitability and safe operating speed should be checked before use.
