Adapter 16x15ml, 2 pcs.

Adapter for 16 round-bottom vessels of 3–15 mL is a centrifuge accessory for 500-mL rectangular buckets used with Rotor A-4-81 and Rotor S-4x500. It positions sixteen tubes of intermediate volume securely inside each bucket, bridging the gap between small collection tubes and larger conical formats. The 3–15 mL range covers widely used laboratory vessels for sample preparation, cell work and routine separations. Supplied as two pieces, the set permits balanced loading of opposing buckets during operation. This adapter from manufacturer Eppendorf matches the geometry of the corresponding rectangular bucket systems, supporting stable tube retention and straightforward handling. Net weight is 0,489 kg and packaging volume is 0,003 m³. Clear tube placement simplifies loading and unloading between runs, while the multi-position layout increases sample throughput without requiring additional rotors. Suitable for clinical, academic and industrial laboratories that already operate A-4-81 or S-4x500 platforms, the accessory helps standardise centrifugation of round-bottom tubes and contributes to consistent, reproducible results across repeated workflows.
