Improve Consistency by Getting the Essentials Right Infographic

Author: Sartorius | Last updated: June 2025 

Overview

Variability doesn’t start with results. It starts at the bench. Small shifts in weighing, liquid handling, or water quality can compromise the integrity of your results. This infographic outlines how errors in essential lab workflows can impact results and contribute to repeat experiments. It highlights five key processes where variability commonly starts and links each to a practical, tool-based improvement. Solutions include high-precision balances that adjust for environmental changes, electronic pipettes that reduce manual variation, and water systems that meet purity standards.

Key takeaways:

  1. Identify five bench-level sources of variability: weighing, pipetting, water purity, ultrafiltration, and microbial QC
  2. See how a balance stabilizes within ±0.005 mg after a 100 mbar pressure shift
  3. Learn how electronic pipettes reduce CVs by up to 50% and log every dispense
  4. Review ultrapure water specs that support trace-level workflows, including PFAS-free output
  5. Understand how tangential flow filtration improves yield by minimizing filter fouling
