Top Mistakes to Avoid While Using Analytical Balances in Laboratories

Introduction

Laboratory scales are sensitive instruments — sometimes accurate to 0.0001 grams. Even the smallest errors in handling or environment can produce incorrect results, waste materials, or worse, lead to failed audits.

At Shree Shree Weighing Solutions, we regularly help clients across Ahmedabad and Gujarat troubleshoot issues due to human errors, incorrect calibration, or environmental mishandling.

Avoid these common mistakes to get the most out of your precision weighing machine.

❌ 1. Not Leveling the Scale

Lab scales must sit on level, vibration-free surfaces. An uneven or shaky platform can:

• Disrupt loadcell function

• Alter readings

• Void calibration

Tip: Use the inbuilt leveling bubble and feet adjustments before use.

❌ 2. Weighing Without Taring

Failing to tare (zero) the scale with the container causes inaccurate net weights.

Tip: Always press the tare button after placing any empty beaker or vessel.

❌ 3. Weighing in Open Rooms or Near Fans

Open airflow can:

• Move powders or liquids

• Affect sensitive readings

• Cause the display to fluctuate

Tip: Always weigh inside the draft shield.

❌ 4. Touching Samples or Pans with Bare Hands

Even the oil from fingertips can alter readings by milligrams.

Tip: Use forceps or gloves for accurate transfers.

❌ 5. Ignoring Calibration Schedules

Many labs calibrate only before audits — but daily or weekly calibration is best practice, especially for sensitive instruments.

Tip: Maintain a digital or physical calibration log for traceability.

❌ 6. Using Expired or Low-Quality Calibration Weights

Poor quality weights compromise your entire weighing protocol.

Tip: Use NABL-certified test weights and recalibrate them annually.

📈 Bonus: Proper Usage = Better Results + Longer Lifespan

By avoiding these mistakes, you:

• Improve accuracy and reproducibility

• Extend your scale’s lifespan

• Pass audits more easily

• Reduce lab rework and costs
