| Product Name | Spinner Salt Powder, 1×, with Phenol Red |
| Catalog No. | RERE-0376 |
| Description | Spinner salt mixtures provide the mildly buffered ionic background on which spinner-flask and other suspension cultures depend. This powder combines potassium chloride, magnesium sulfate, sodium chloride, sodium bicarbonate and the pH indicator phenol red; dissolved in water it yields a 1× solution ready for use. Because bicarbonate is heat-labile in this formulation, sterilisation must be achieved by filtration rather than autoclaving. |
| Intended Use | Preparation of buffered salt solution for suspension culture vessels and related pH-controlled applications. |
| Principle / Technology | Bicarbonate and phosphate-compatible salts buffer pH while phenol red offers a visible acidity cue. |
| Specificity | 1× after reconstitution; contains phenol red; composed of KCl, MgSO4, NaCl, NaHCO3 and phenol red. |
| Reaction Conditions / Protocol | Dissolve the powder in water and filter-sterilise; do not autoclave, as heating degrades the bicarbonate component. |
| Storage Conditions | Room temperature; 12 months. |
| Package Specifications | 1 L, 10 L, 10 × 1 L |
| Key Features | Phenol red indicator included; filter-sterilise only; powder format keeps storage simple. |
For research use only, not for clinical use.
