Keeps the sensor constantly emerged and running fine. ## Features - One 125ml (4oz) pH / ORP Electrode Storage Solution - Protects pH / ORP Probes From Drying Out - Works with all pH & ORP Probes - Standardized against NIST-Certified References - 2 year Shelf Life at Room Temperature ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0071AR9XI | | Best Sellers Rank | #287,422 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #7 in Electrolyte Solutions | | Brand | Atlas Scientific | | Brand Name | Atlas Scientific | | Container Type | Bottle | | Country Of Origin | USA | | Customer Reviews | 4.7 out of 5 stars 390 Reviews | | Global Trade Identification Number | 00857434005350 | | Item Form | Liquid | | Item Volume | 250 Millilitres | | Manufacturer | Atlas Scientific | | Manufacturer Part Number | ATL-phStorage | | Model Number | ATL-phStorage | | Package Information | Bottle | | Volume | 250 Millilitres | ## Product Details - **Brand:** Atlas Scientific - **Item Volume:** 250 Millilitres - **Package Information:** Bottle - **Item Form:** Liquid - **Manufacturer:** Atlas Scientific ## Images ![Atlas Scientific pH/ORP Electrode Storage Solution 250ml (8oz) - Image 1](https://m.media-amazon.com/images/I/61TksZO6JXL.jpg) ![Atlas Scientific pH/ORP Electrode Storage Solution 250ml (8oz) - Image 2](https://m.media-amazon.com/images/I/61gzG5UynKL.jpg) ![Atlas Scientific pH/ORP Electrode Storage Solution 250ml (8oz) - Image 3](https://m.media-amazon.com/images/I/614sML8sD4L.jpg) ![Atlas Scientific pH/ORP Electrode Storage Solution 250ml (8oz) - Image 4](https://m.media-amazon.com/images/I/615q4h1xiwL.jpg) ## Questions & Answers **Q: Can this be used to sterilize soil?** A: NO.
