The Entris® II Essential line is designed for basic to intermediate weighing tasks, offering core features like isoCAL automatic calibration, LED touch technology, and 12 built-in applications at a budget-friendly price. The Advanced models add premium features such as a graphic touch display, CaluTrail documentation, pipette calibration, and dual USB-C ports for enhanced connectivity. Both lines share Sartorius' high-quality German engineering but cater to different user needs and budgets.
The isoCAL system is an internal calibration feature that automatically adjusts the balance based on temperature changes (1.5K threshold) or time intervals (every 4-6 hours). It ensures compliance with SOP and GLP requirements without manual calibration weights. For optimal accuracy, Sartorius recommends periodic external calibration (every 3-6 months) using certified weights, especially in regulated environments like pharmaceuticals.
The minimum sample weight depends on the model’s readability:
1.) 0.1mg readability models: Minimum 0.082g (USP Chapter 41 compliant)
2.) 1mg readability models: Minimum 0.82g
3.) 10mg readability models: Minimum 8.2g
For high-precision applications, always weigh samples at least 10x the readability to ensure reliable results.
Yes, the balance supports multiple connectivity options:
1.) USB-C for direct data transfer to PCs (Excel/Word) or Sartorius printers
2.) RS232 for legacy systems and lab equipment
3.) Second display for remote viewing
4.) GLP/GMP-compliant printouts with date/time stamps for documentation
To maintain peak performance:
1.) Clean regularly with a soft cloth (avoid harsh chemicals)
2.) Check calibration periodically (isoCAL automates this, but external verification is recommended)
3.) Store properly in a stable environment (avoid extreme temperatures/humidity)
4.) Use anti-vibration tables in high-traffic labs to minimize disturbances
5.) Replace worn parts (e.g., draft shield seals, weighing pan) as needed
For troubleshooting, refer to the error codes (e.g., "Err-3" for calibration issues) in the manual or contact Sartorius support.
