Frequently asked questions
Common questions about LABCHEM from 3G Electric.
What pH values are available in the LABCHEM pH buffer line?
LABCHEM pH buffers are offered at pH 4.00, pH 7.00, and pH 10.00. These cover acidic, neutral, and alkaline calibration points. Some products are color-coded: red for pH 4.00, yellow for pH 7.00, and blue for pH 10.00. A buffer set containing all three values is also available. The buffers are liquid solutions in plastic containers, with volumes from 500 mL to 20 L. They are lab grade and include CAS numbers for traceability. This range supports routine calibration and verification of pH meters and electrodes across different measurement ranges.
What is the CAS number for LABCHEM pH 7.00 buffer?
The CAS number varies by specific product. For example, SKU 8PYJ2 (pH 7.00, 500 mL) lists CAS 1310-73-2, while SKU 8ZL40 (pH 7.00, 1 L, color-coded yellow) and SKU 9TEN8 (pH 7.00, 20 L) list CAS 7732-18-5. Always refer to the product datasheet or label for the exact CAS number of the buffer you are using. This information is important for compliance and safety documentation. 3G Electric can provide the relevant datasheets for each SKU upon request.
What container sizes are available for LABCHEM pH buffers?
LABCHEM pH buffers are supplied in plastic bottles or containers in several sizes: 500 mL, 1 L, 4 L, 10 L, and 20 L. Smaller volumes are typically used for benchtop calibration, while larger volumes suit higher-throughput or industrial settings. Some larger containers are packaged in boxes for protection during shipping. The container material is plastic, which is compatible with the buffer solutions. When ordering, specify the desired volume and pH value to ensure you receive the correct SKU. 3G Electric stocks multiple sizes to accommodate different usage rates.
Can LABCHEM pH buffers be used for industrial pH meter calibration?
Yes, LABCHEM pH buffers are lab grade and are used for calibrating and verifying pH meters and electrodes in laboratory and industrial settings. They provide reference points at pH 4.00, 7.00, and 10.00. For industrial applications, larger container sizes such as 10 L or 20 L may be more practical. The buffers are formulated with known CAS-numbered components, which helps with documentation. However, always follow your instrument manufacturer's calibration procedure and consider the specific requirements of your process, such as temperature compensation and buffer freshness.
What is the difference between LABCHEM pH 4.00 buffer and pH 10.00 buffer?
The primary difference is the pH value: pH 4.00 is acidic, while pH 10.00 is alkaline. Both are used for calibration, but they bracket the neutral point (pH 7.00) to allow multi-point calibration. LABCHEM pH 4.00 buffer is often color-coded red, and pH 10.00 is color-coded blue, which helps prevent mix-ups. The chemical composition and CAS numbers may differ; for instance, pH 4.00 buffer may use CAS 877-24-7 or 7732-18-5, while pH 10.00 may use CAS 7732-18-5. Always check the product label for exact composition.
Does 3G Electric provide datasheets for LABCHEM pH buffers?
Yes, 3G Electric can provide datasheets for LABCHEM pH buffer products. These datasheets include specifications such as pH value, volume, container type, CAS number, and manufacturer part number. They are useful for quality records, safety assessments, and procurement documentation. When requesting a quote or placing an order, you can ask for the datasheet of the specific SKU. 3G Electric supports global delivery and can assist with logistics for both small and bulk orders.
