Applications and Experiments for the Screw Cap Conical Tube
The conical bottom gathers sediment or a pellet into a small point during centrifugation, so the liquid above can be poured or pipetted off cleanly. The wide neck makes filling easier, the graduations give the sample volume, and the screw cap keeps the contents closed while the tube spins or is stored.
- DMLT and B.Sc. MLT: urine sediment preparation and other routine centrifugation steps.
- B.Sc. Biotechnology and Microbiology: harvesting cells and separating supernatants in 15 ml or 50 ml volumes.
- Transferring a specimen from a Container Sample 50 ml into a graduated tube before spinning.
- Making up larger liquid volumes in a Cylinder Measuring Plastic and dividing them into 50 ml tubes.
Standard Scope of Supply
The Screw Cap Conic Tube is supplied as a single graduated PET tube with its screw cap, in the 15 ml or the 50 ml size you specify. Centrifuges, racks and mixers are separate items, and any of them can be added to the same quotation as the tubes.
Packing, MOQ and Lead Time
State the size, 15 ml or 50 ml, and the quantity of each when you request a quotation; a small trial lot and a full laboratory stock can both be quoted. Science Lab Supplies then gives the packing, delivery time and price, with racks or centrifuges on the same quote if needed.
With its Importer-Exporter Code, Science Lab Supplies can ship to buyers in the UAE, Saudi Arabia, Oman, the Philippines, Nepal and Bangladesh. To order conical tubes, get in touch from the contact page or record the sizes in the enquiry cart; tender buyers can refer to the lab tender page.
Frequently Asked Questions
Which sizes does the Screw Cap Conic Tube come in?
It comes in 15 ml and 50 ml capacities. Both sizes are graduated PET tubes with a conical bottom, a wide neck and a screw cap, so specify the size and quantity of each when you ask for a quotation.
Can the tube be used in a centrifuge?
Yes. It is a test tube for routine centrifugation. Check the bucket or adapter size and the speed rating of your centrifuge before spinning, and always balance tubes of equal volume opposite each other.
Why does the tube have a conical bottom?
A conical bottom concentrates sediment or cells into a small pellet at the tip during centrifugation, which makes it easier to remove the liquid above without disturbing the material collected at the bottom.
Who supplies the Screw Cap Conic Tube?
The conical tubes are supplied through Science Lab Supplies in Ambala, India, which quotes both sizes for laboratories, colleges, training institutes and distributors and can group them with racks and centrifuges in one consignment.
