# Little Creatures Zoo — Lab-Grade pH Calibration Fluid (pH 7.00 & pH 10.00)
**Ensure peak sensor accuracy, eliminate measurement drift, and protect your aquatic ecosystem.**
Little Creatures Zoo Precision pH Calibration Fluids are laboratory-formulated reference standards engineered for continuous-immersion pH probes, automated aquarium controllers, and digital meters. Formulated for high-precision two-point calibration across neutral (7.00) and high-alkaline (10.00) marine ranges.
Over time, all pH probes experience electronic drift and bio-fouling. Regular two-point calibration with reliable standards ensures your automated dosing systems, calcium reactors, and pH monitors report accurate real-time data.
Our pH 7.00 (Neutral) and pH 10.00 (High-Range Alkaline) solutions are batch-tested for high stability and minimal thermal variance—ideal for marine aquariums, coral propagation, and automated lab setups.
#### Compatible Hardware & Automated Controllers

### Key Features & Specifications
* **Volume:** 250ml per bottle — yields up to **10 calibration tests** (depending on sample vial size).
* **Two-Point Calibration:** Covers the critical marine operating spectrum (pH 7.00 neutral baseline and pH 10.00 alkaline upper range).
* **Accuracy:** ±0.02 pH @ 25°C.
* **Available Options:** pH 7.00 Standard, pH 10.00 Standard, or 2-Pack Calibration Set (7.00 + 10.00).
### Usage Guidelines & Care
1. **Pour Off Sample:** Always pour a small aliquot into a clean, separate sample cup or vial for testing. **Do not submerge probes, tools, or pipettes directly into the bottle** to prevent cross-contamination of the primary solution.
2. **Calibrate:** Rinse probe thoroughly with RODI water, blot dry with a lint-free wipe, and perform calibration per your device manufacturer's instructions.
3. **Dispose:** Always discard used fluid after testing—never pour used calibration fluid back into the bottle.
#### Storage & Shelf Life
* **Shelf Life:** Recommended for use within **6 months** of opening for optimal precision.
* **Storage:** Keep cap tightly sealed and store in a **cool, dry place**
out of direct sunlight.
