Screw Cap Conic Tube Manufacturer,Supplier and Exporter in India

Screw Cap Conic Tube (Product Code: SLE/CL/41) is a graduated, conical-bottom test tube made of polyethylene terephthalate (PET) with a screw cap and wide neck, designed for routine centrifugation. It is offered in 15ml and 50ml capacities and is used in hospital laboratories and reference centres for a variety of tests, from sediment preparation to sample aliquoting. The tube is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a lab plastic ware supplier in India serving clinical and research buyers.

Specifications

Typical Use

The conical base gathers solids into a small, tight pellet during spinning, which is why these tubes are used for urine sediment work, washing cell suspensions, concentrating specimens and separating liquids before analysis. The wide neck makes it easy to pour or pipette samples in, the graduations give a quick visual check of volume, and the screw cap helps contain splashes and aerosols while the tube is handled or centrifuged.

Always load tubes in balanced pairs of the same size and fill level, and make sure your rotor or buckets accept conical tubes of the capacity you choose before ordering. Many buyers pair the 15ml size with a benchtop laboratory centrifuge in India for routine clinical work and use the 50ml size for larger preparation or transport volumes. After spinning, remove the supernatant carefully with a pipette so the pellet is not disturbed.
