Product Description
When it comes to precise pH measurements in your lab, accuracy starts with reliable calibration. These pH 4 buffer tablets from Avantor provide a convenient, pre-measured solution for calibrating pH meters and electrodes. Each tablet dissolves quickly in distilled water to create a stable pH 4.00 ± 0.02 solution, ensuring your equipment delivers consistent results every time.
Designed for laboratory use, these LR-grade tablets meet stringent quality standards, making them ideal for educational institutions, research facilities, and industrial labs. The compact tablet form eliminates the need for messy liquid buffers while maintaining the same level of precision. Whether you’re a student learning pH calibration techniques or a researcher conducting critical experiments, these buffer tablets offer the reliability you need.

Using buffer tablets is straightforward. Simply dissolve one tablet in 100 mL of distilled water to prepare your calibration solution. The tablets are pre-weighed to ensure consistent concentration, reducing human error in preparation. This makes them particularly valuable in teaching labs where students are still developing their technique.
The LR grade designation indicates these tablets are suitable for general laboratory applications where high purity isn’t required but consistent performance is essential. They’re perfect for routine pH meter calibration, quality control checks, and educational demonstrations. For more demanding applications, consider our analytical grade buffer solutions also available at eqipped.
Proper pH calibration is fundamental to accurate experimental results. These pH 4 buffer tablets help maintain your equipment’s precision between calibrations, giving you confidence in your measurements. They’re also cost-effective, with each pack containing 20 tablets – enough for multiple calibration sessions.
How to Use pH 4 Buffer Tablets
1. Fill a clean beaker with 100 mL of distilled water. 2. Drop one buffer tablet into the water. 3. Stir gently until completely dissolved. 4. Use the solution immediately for pH meter calibration. 5. Discard the solution after use – do not reuse.
Storage and Handling
Store buffer tablets in their original container at room temperature, away from moisture and direct sunlight. Always use clean, dry utensils when handling tablets to prevent contamination. Keep the container tightly sealed when not in use to maintain tablet integrity.
Safety Information
While these buffer tablets are generally safe for laboratory use, always follow standard lab safety procedures. Wear appropriate personal protective equipment when handling chemical solutions. The prepared buffer solution should be disposed of according to your institution’s chemical waste guidelines.
FAQs
What is the shelf life of these pH 4 buffer tablets?
When stored properly in their original packaging, these buffer tablets typically have a shelf life of 2-3 years. Always check the expiration date on the package before use.
Can I use tap water instead of distilled water to prepare the buffer solution?
We recommend using distilled or deionized water for preparing buffer solutions to avoid interference from minerals or contaminants present in tap water that could affect pH accuracy.
How often should I calibrate my pH meter using these buffer tablets?
Calibration frequency depends on your usage. For routine lab work, weekly calibration is recommended. For critical measurements, daily calibration may be necessary. Always calibrate when you notice inconsistent readings.
Are these buffer tablets suitable for food industry applications?
These LR-grade tablets are designed for general laboratory use. For food industry applications, we recommend our food-grade buffer solutions that meet specific regulatory requirements.
What’s the difference between pH 4 and pH 7 buffer tablets?
pH 4 buffer tablets create an acidic solution for calibrating the lower end of your pH meter’s range, while pH 7 tablets create a neutral solution. Most calibration procedures use both to ensure accuracy across the pH scale.
