Tube Riser Adaptor (SKU 111579) Overview
The Globe Scientific Tube Riser Adaptor bridges the size gap between small-format tubes and larger rotor cavities. This adaptor positions a 5mL Diamond Midi centrifuge tube securely inside a 15mL centrifuge cavity, eliminating the need for dedicated small-tube rotors. Labs running mixed sample volumes gain flexibility without buying additional hardware.
Molded from polypropylene (PP), each adaptor resists common laboratory chemicals and tolerates routine spin cycles. Technicians simply drop the riser into the 15mL cavity, then seat the 5mL tube on top for stable, centered support during centrifugation.
Sold in bags of four, this consumable suits high-throughput facilities that standardize on the Diamond Midi tube line. Procurement teams can scale orders from single bags up to full master cases.

Laboratory Applications
Mixed-volume sample processing benefits directly from this adaptor. Research and clinical labs frequently handle small-volume specimens that must spin in rotors designed for larger tubes. Placing the riser into a 15mL cavity lets staff process 5mL Diamond Midi tubes on existing equipment, supporting workflows in molecular biology, sample prep, and routine separations.
Standardization is another draw for busy facilities. Teams that have adopted the Diamond Midi tube format can keep a uniform consumable kit across centrifuges. Adaptors reduce the inventory of specialty rotors and help technicians transition between tube sizes during multi-step protocols.

Frequently Asked Questions
What tube and cavity sizes does this adaptor fit?
This adaptor holds a 5mL Diamond Midi centrifuge tube and seats inside a standard 15mL centrifuge cavity, letting smaller tubes run in larger rotor positions.
What material is the riser made from?
Globe Scientific molds the adaptor from polypropylene (PP), a material widely used for centrifuge consumables due to its chemical resistance.
How many adaptors come in a pack?
Adaptors are sold in bags of 4. Master cases hold 250 units, and bulk orders are available through LabSupplies.com.
