Frequently asked questions
Common questions about MICRO ESSENTIAL from 3G Electric.
What is the concentration tolerance for MICRO ESSENTIAL pH buffer capsules?
MICRO ESSENTIAL pH buffer capsules are specified at a concentration of ±0.02 pH units. For example, the pH 4.00 buffer is rated at pH 4.00 ± 0.02, the pH 7.00 buffer at pH 7.00 ± 0.02, and the pH 10.00 buffer at pH 10.00 ± 0.02. This tolerance applies to the solution produced after the capsule is dissolved in the specified volume of water. Buyers should verify that this tolerance meets the requirements of their calibration procedure or quality standard.
What volume of buffer solution does each MICRO ESSENTIAL capsule produce?
Individual MICRO ESSENTIAL buffer capsules (SKUs 3TXF1, 3TXF4, 3TXF7) each produce 20 mL of solution. The MICRO ESSENTIAL buffer set (SKU 3TXE7) contains three capsules that each produce 100 mL of solution. The volume yield determines how many calibration points or how much electrode immersion is possible per capsule. For routine calibration of a single pH electrode, 20 mL is typically sufficient. The 100 mL set format is suited to larger electrodes or multiple calibration sessions from one preparation.
How are MICRO ESSENTIAL pH buffers color-coded?
MICRO ESSENTIAL uses color coding to identify buffer values. The pH 4.00 buffer is color-coded red, the pH 7.00 buffer is color-coded green, and the pH 10.00 buffer is color-coded blue. This coding is applied to the capsule or its packaging to allow quick visual distinction during calibration. The color coding does not indicate the chemical composition or grade; it is an identification aid only. Users should still confirm the pH value from the label before use.
What chemical grade are MICRO ESSENTIAL pH buffer capsules?
MICRO ESSENTIAL pH buffer capsules are classified as lab-grade chemicals. This grade is suitable for general laboratory calibration and verification of pH meters and electrodes. It is not a certified reference material (CRM) grade unless explicitly stated on the product documentation. For applications requiring traceable standards, buyers should request the certificate of analysis or specification sheet for the specific lot. 3G Electric can provide available datasheets for the SKUs in this line.
Can MICRO ESSENTIAL pH buffer capsules be used for industrial water treatment calibration?
Yes. The product descriptions for MICRO ESSENTIAL pH buffers list laboratory and industrial water treatment as application areas. The capsules are used to calibrate pH meters and electrodes that monitor or control water treatment processes. The 20 mL and 100 mL yield formats allow calibration in field or plant settings where preparing bulk buffer solutions is impractical. Users should follow their site's calibration schedule and verify that the buffer's ±0.02 tolerance and lab-grade classification meet the measurement uncertainty requirements of the process.
What SKUs are available in the MICRO ESSENTIAL pH buffer line from 3G Electric?
3G Electric carries the following MICRO ESSENTIAL pH buffer SKUs: 3TXF1 (pH 4.00 buffer, red, 20 mL per capsule), 3TXF4 (pH 7.00 buffer, green, 20 mL per capsule), 3TXF7 (pH 10.00 buffer, blue, 20 mL per capsule), and 3TXE7 (buffer set containing pH 4.00, 7.00, and 10.00 capsules, each yielding 100 mL). Availability and packaging quantities can vary. Contact 3G Electric for current stock, datasheets, and quotes for specific SKUs.
