Adapter 9x7ml, verp.

Adapter 9 × 7 ml is a centrifuge adapter for nine round-bottom vessels in the 2,6–7 mL range. It fits 100 mL rectangular buckets used in rotor A-4-44 and provides secure positioning of intermediate-volume tubes during laboratory spin protocols. Delivered as two pieces per pack, the adapter allows balanced dual-bucket operation and simplifies switching between tube formats without exchanging the rotor. This accessory is from manufacturer Eppendorf and is intended for centrifuges configured with the A-4-44 rotor and corresponding rectangular buckets. Net weight is 0,280 kg and gross weight 0,311 kg, with a packaging volume of 0,002 m³, so the set is practical for storage beside the instrument. Laboratories use such adapters for sample concentration, phase separation, washing steps and routine preparation work in life-science, analytical and clinical settings where 2,6–7 mL round-bottom vessels are standard. The nine-place layout supports efficient batch handling while maintaining alignment under centrifugal force, helping operators keep workflows consistent across repeated runs and shared instrument schedules.
