Examples

• The saline solution was prepared isosmotically to match the osmotic pressure of blood plasma.
• Cells were suspended isosmotically to prevent water movement across the cell membrane.
• The intravenous fluid was administered isosmotically to avoid damaging red blood cells.
• Researchers cultured the organisms isosmotically to maintain cellular integrity.
• The two solutions were balanced isosmotically for the experiment.
