| Product Name | Spinner Salt Powder, 1×, without Phenol Red |
| Catalog No. | RERE-0377 |
| Description | For experiments where a colored indicator would interfere with spectrophotometric readings or downstream assays, this phenol red-free spinner salt powder supplies the same buffered ionic backbone minus the dye. Potassium chloride, magnesium sulfate, sodium chloride and sodium bicarbonate dissolve into a 1× working solution suited to suspension culture support. Sterilise by filtration once dissolved, since autoclaving would compromise the bicarbonate. |
| Intended Use | Buffered salt support for suspension cultures and assays that require an indicator-free background. |
| Principle / Technology | Physiological salts with bicarbonate maintain pH balance without any added colorant. |
| Specificity | 1× after reconstitution; phenol red-free; composed of KCl, MgSO4, NaCl and NaHCO3. |
| Reaction Conditions / Protocol | Dissolve in water and sterilise by filtration rather than autoclaving. |
| Storage Conditions | Room temperature; 12 months. |
| Package Specifications | 1 L, 10 L, 10 × 1 L |
| Key Features | No pH indicator; clean optical background for absorbance-based assays; long-life powder format. |
For research use only, not for clinical use.
