Designed for professionals demanding accuracy, it includes color-coded solutions and a CalPod holder to streamline your calibration process, ensuring your pH and EC meters deliver reliable, repeatable results every time. ## Description Aprea Instruments AI1105 pH/EC Calibration Buffer Solution Kit includes two 8oz. bottles of pH buffer solutions (pH 4. 00 and pH 7. 00), and two 8oz bottles of conductivity (EC) standard calibration solutions (1413 µS/cm and 12. 88 mS/cm), one 4oz bottle of 3M KCL storage solution for pH/ORP electrodes, plus one piece of Aprea CalPod Solution Holder, which helps users organize all the solutions in one place and streamline the entire calibration process. All the buffer solutions are standardized against NIST certified references at 25˚C (77˚F). It’s ideal for the calibration of all pH and conductivity meters. Since pH and conductivity value is affected by temperature, the temperature & pH/conductivity reference charts are provided on the bottle labels for reference. The 3M KCL Storage Solution helps keep the sensitivity and accuracy of your pH probes. All the solutions are double-sealed, not subject to the DOT shipping restrictions, and have a 2-year shelf life (1-year for conductivity solutions). Keeping the standard solutions fresh and uncontaminated is the precondition for accurate pH measurement. Pour 2-3 oz. of solution into a clean container for calibration. If sealed well, the same amount of pH solution poured out can be used for 10-15 times before replacement (conductivity solution up to 5 times). Never pour the used solution back to the original bottle to avoid contamination. The expiration date is printed on the bottle. MSDS documents are downloadable. COA can be achieved per request. Note: Store at room temperature and away from direct sunlight. Keep the bottle tightly closed when not in use. Keep out of reach of children. ## Features - Reported pH values are accurate to +/- 0.01 pH at 25 °C and are traceable to NIST Standard Reference Materials (SRMs). - Produced in an ISO 9001:2015 certified facility using high-purity reagents, deionized water and certified analytical balances in a temperature controlled environment. - color-coded for quick identification. - Apera CalPod solution holder is included for organizing all the buffers and streamlining your calibration process. - Double-sealed. 2-year expiration for pH and 1-year for conductivity for an unopened bottle. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MY12Z54 | | Best Sellers Rank | #12,105 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #6 in Chemical Buffers | | Brand Name | Apera Instruments | | Container Type | Bottle | | Customer Reviews | 4.7 4.7 out of 5 stars (256) | | Included Components | AI1105 pH/conductivity solution kit | | Item Form | Liquid | | Item Weight | 9 Ounces | | Manufacturer | Apera Instruments | | Model Number | AI1105 | | Part Number | AI1105 | | UPC | 858718006452 | | Unit Count | 1.0 Count | | Volume | 8 Fluid Ounces | ## Product Details - **Brand:** Apera Instruments - **Item Form:** Liquid - **Item Volume:** 8 Fluid Ounces - **Item Weight:** 9 Ounces - **Package Information:** Bottle ## Images ![Apera Instruments AI1105 8oz. pH/EC Calibration Solution Kit (pH 7.00, 4.00, 1413 µS, 12.88 mS), Plus 3M KCL Soaking Storage Solution & CalPod Solution Holder - Image 1](https://m.media-amazon.com/images/I/61LJ2kz4oiL.jpg) ![Apera Instruments AI1105 8oz. pH/EC Calibration Solution Kit (pH 7.00, 4.00, 1413 µS, 12.88 mS), Plus 3M KCL Soaking Storage Solution & CalPod Solution Holder - Image 2](https://m.media-amazon.com/images/I/4139fYPbzeL.jpg) ## Available Options This product comes in different **Style** options. ## Frequently Bought Together - 8oz. pH/EC Calibration Solution Kit (pH 7.00, 4.00, 1413 µS, 12.88 mS), plus 3M KCL Storage Solution & CalBox - Apera Instruments AI311 Premium Series PH60 Waterproof pH Pocket Tester Kit, Replaceable Probe, ±0.01 pH Accuracy, Lcd display - Apera Instruments 3M KCL Storage Soaking Solution (8 oz.) for pH and ORP Electrodes --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ni/products/38158901-apera-instruments-ai1105-8oz-ph-ec-calibration-solution-kit-ph](https://www.desertcart.ni/products/38158901-apera-instruments-ai1105-8oz-ph-ec-calibration-solution-kit-ph) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-07-08*
