Buffer Solution Price in Bangladesh 2026
Buffer solution price in Bangladesh sits at ৳3,500 across all three Hanna calibration standards — pH 4.01, 7.01, and 10.01. ASTZ stocks genuine Hanna (USA) buffer solutions, giving your pH meter the accurate calibration reference it needs before any real measurement.
A pH meter is only as accurate as its last calibration. Skip a proper buffer solution, or use one past its shelf life, and every reading that follows carries that error forward. Getting the right buffer on hand matters more than most labs realize until a result comes back wrong.
What is a Buffer Solution? (Overview)
A buffer solution is a chemical solution with a precisely known, stable pH value, used specifically to calibrate pH meters and electrodes against a trusted reference point.
How a Buffer Solution Resists pH Change
A buffer resists pH change because it contains a weak acid and its conjugate base (or a weak base and its conjugate acid) in balance. When small amounts of acid or alkali are introduced, the buffer’s chemistry absorbs the shift, holding the pH steady at its labeled value.
Why pH Meters Need Buffer Solution for Calibration
Every pH electrode drifts slightly over time and use. Calibrating against a buffer solution with a known, certified pH value resets the meter’s reading to match that known standard, correcting for that drift before you trust the meter with an actual sample.
Buffer Solutions We Offer
Hanna HI7004 — pH 4.01 Buffer Solution
The HI7004 provides a certified pH 4.01 reference, the standard low-end calibration point for acidic sample ranges. Price: ৳3,500.
Hanna HI7007 — pH 7.01 Buffer Solution
The HI7007 delivers a neutral pH 7.01 reference point, the calibration standard every pH meter should be checked against regardless of what you’re measuring. Price: ৳3,500.
Hanna HI7010 — pH 10.01 Buffer Solution (1L Bottle)
The HI7010 covers the alkaline end at pH 10.01, sold in a larger 1L bottle for labs running frequent calibrations. Price: ৳3,500.
pH 4.01 vs 7.01 vs 10.01 — Which Buffer Do You Need?
| Buffer | pH Value | Use Case | When to Calibrate With It |
|---|---|---|---|
| Hanna HI7004 | 4.01 | Acidic sample calibration | Testing acidic solutions, soil, fruit juices |
| Hanna HI7007 | 7.01 | Neutral reference point | Always included in every calibration routine |
| Hanna HI7010 | 10.01 | Alkaline sample calibration | Testing alkaline solutions, wastewater, detergents |
A proper calibration always includes pH 7.01 as your baseline, paired with either the 4.01 or 10.01 buffer depending on which side of neutral your actual samples fall on.
Buffer Solution Price in Bangladesh

| Hanna HI7007 | 7.01 | Standard bottle | 3,500 | Neutral baseline calibration |
| Hanna HI7010 | 10.01 | 1L bottle | 3,500 | Alkaline range calibration |
Applications of Buffer Solution
pH Meter & Electrode Calibration
The core use — buffer solution is what turns a pH meter from a guess into a trusted measurement tool, and this needs to happen before every serious testing session.
Laboratory & Research Analysis
Research labs rely on properly calibrated pH readings for reproducible results across experiments, chemical formulations, and sample analysis.
Water Treatment & Environmental Testing
Treatment plants calibrate pH meters regularly to confirm water quality readings remain accurate for regulatory reporting and process control.
Food, Beverage & Pharmaceutical Quality Control
Product pH directly affects shelf life, safety, and formulation consistency, making regular meter calibration a routine QC requirement in these industries.
Aquaculture & Agriculture pH Monitoring
Fish farms and soil testing operations depend on accurate pH readings to maintain healthy growing conditions, which starts with a properly calibrated meter.
Who Needs Buffer Solution in Bangladesh
Lab Technicians & Researchers
Anyone running pH-dependent experiments needs fresh buffer solution on hand for routine and pre-experiment calibration.
Water Treatment Plant Operators
Regular calibration is part of standard operating procedure for maintaining accurate, compliant water quality monitoring.
Food & Pharmaceutical QC Teams
Quality control processes in these industries typically require documented, regular pH meter calibration as part of compliance standards.
Students & Educational Institutions
Chemistry and environmental science labs need buffer solution stocked for practical coursework involving pH measurement.
Why Choose ASTZ for Buffer Solution in Bangladesh
Genuine Hanna (USA) Instruments
Hanna Instruments is an established name in pH measurement, and every bottle we sell is genuine, not a relabeled or diluted substitute.
Accurate, Traceable pH Values for Reliable Calibration
A calibration is only as good as the buffer behind it — Hanna’s certified pH values give you a dependable reference every time.
Warranty, Support & Nationwide Delivery
Our team is available for support questions, with delivery available across Bangladesh so labs outside Dhaka can restock without delay.
How to Choose & Use the Right Buffer Solution
Match Buffer pH to Your Expected Sample Range
If your samples typically read acidic, calibrate with the 4.01 buffer alongside 7.01. For alkaline samples, pair 7.01 with the 10.01 buffer instead.
Always Calibrate with pH 7 Plus One Other Value
A single-point calibration at pH 7 alone isn’t enough for accurate readings across a range — pairing it with either the 4.01 or 10.01 buffer gives your meter a proper two-point calibration.
Storage & Shelf Life Tips for Buffer Solution
Keep bottles tightly sealed when not in use, avoid contaminating the bottle by dipping used electrodes directly back in, and replace buffer solution once it’s past its usable shelf life or shows signs of contamination.
Buffer Solution Price Range in Bangladesh (2026)

Frequently Asked Questions — FAQ
What is the price of buffer solution in Bangladesh?
All three Hanna buffer solutions — pH 4.01, 7.01, and 10.01 — are priced at ৳3,500 each at ASTZ.
What is a buffer solution used for?
Buffer solution is used to calibrate pH meters and electrodes against a known, stable pH reference before taking actual measurements.
Why do I need pH 4, 7, and 10 buffer solutions together?
A proper calibration needs pH 7.01 as a neutral baseline, plus either the 4.01 or 10.01 buffer depending on whether your samples fall on the acidic or alkaline side — having all three covers both scenarios.
Can buffer solution be reused after calibration?
No, buffer solution used for calibration should not be poured back into its original bottle, as contact with the electrode introduces contamination that affects future calibration accuracy.
What are the benefits of buying from ASTZ?
Genuine Hanna (USA) buffer solutions, accurate certified pH values, and delivery support across Bangladesh.
