This category covers conical centrifuge tubes, mostly in the standard 15 mL and 50 mL sizes, plus 10, 25 and 30 mL options. Nearly all are polypropylene with flat screw caps and come sterile or non-sterile, packed in racks, re-sealable bags or bulk bags. You will also find self-standing (skirted) 50 mL tubes, tubes with printed graduations and writing areas, metal-free tubes for trace analysis, amber tubes for light-sensitive samples, centrifuge tube filters, and caps or tubes sold separately. Products come from CELLTREAT, MTC Bio, Globe Scientific, Biologix, Labcon and others.

Start with volume and outside dimensions, which must fit your rotor or adapter; listings give sizes such as 17 x 118 mm for 15 mL and 29 x 115 mm for 50 mL. Choose sterile tubes for cell culture and sample work, and non-sterile bulk packs for general use. Decide between conical and self-standing bottoms, check the maximum RCF rating against your run speed, and compare the pack format, since racks are easier to handle and bags take less space.

15 and 50 ML Centrifuge Tubes: common questions

What are the dimensions of a 15 mL centrifuge tube?

Most 15 mL conical tubes are about 17 mm in outside diameter and roughly 118 to 120 mm long with the cap, and several listings in this category give 17 x 118 mm or 17 x 120 mm. A 50 mL conical tube is typically about 29 to 30 mm wide and 114 to 115 mm long. Dimensions vary slightly by manufacturer, so check the listing against your rotor buckets or adapters before ordering.

Are polypropylene centrifuge tubes better than polystyrene?

For most centrifuge work, yes. Polypropylene withstands higher centrifugal force and resists many organic solvents better than polystyrene, which is why it is the usual material for conical tubes. Polystyrene is clearer, which helps when you need to see small pellets or color changes, but it cracks more easily and is attacked by solvents such as acetone and chloroform. Always check the manufacturer's maximum RCF rating for the specific tube.

Should I buy sterile or non-sterile centrifuge tubes?

Use sterile tubes for cell culture, microbiology and any work where contamination would affect results, such as cell pellets or clinical samples. Non-sterile tubes are fine for buffer preparation, chemical samples and general storage, and they usually cost less per tube. Sterile tubes are often certified free of DNase, RNase and pyrogens, but confirm this on the individual product listing if your application needs it.

Can I return centrifuge tubes ordered from LPS?

Returns are accepted within 30 days by mail, with the customer paying return shipping. Sterile items are an exception and cannot be returned, which covers many of the tubes in this category, so confirm size, cap style and sterility before ordering. For large or repeat orders you can request volume pricing through the Contact Us page.
