Entris II Advanced (BCA) Analytical Balance
The Sartorius Entris II Advanced (BCA) analytical balances weigh 60 g, 120 g, 220 g or 320 g with 0.1 mg readability and a typical stabilization time of 1.5 seconds or less. A graphic touch display, real-time level support, integrated protection systems, CalAuditTrail and 13 built-in applications add value to the Entris II range; "i" models also offer isoCAL internal adjustment.
Overview
The Sartorius Entris II Advanced (BCA) Analytical Balances are best-value laboratory balances for everyday analytical weighing at 0.1 mg, with extra features that simplify daily work and documentation. Seven models cover the range:
Internal adjustment (isoCAL): BCA324i-1S (320 g), BCA224i-1S (220 g), BCA124i-1S (120 g) and BCA64i-1S (60 g).
External adjustment: BCA224-1S (220 g), BCA124-1S (120 g) and BCA64-1S (60 g).
What the Advanced line adds
Real-time level support: an internal electronic level sensor monitors the level continuously, raises an alarm if it is not correct and guides you interactively through levelling.
Integrated protection systems: three configurable levels decide which weighing data is valid, so only valid data is passed to external devices.
CalAuditTrail: calibration processes are documented automatically with the calibration trigger and a date and time stamp.
Graphic touch display: an intuitive graphic touch display and user management control access to the balance settings.
Quality built in
A monolithic weigh cell, a fast stabilization time and parts made of hard-wearing PBT, stainless steel and glass give accurate, durable results that are easy to clean. Specially coated glass parts of the draft shield minimize errors caused by electrostatically charged samples. On the "i" models the fully automated isoCAL adjustment is controlled by internal temperature and time, with a notification if calibration is outside the normal range.
Plug-and-play connectivity
The balance detects Sartorius accessories such as a printer or a second display automatically. A USB Type-C interface, a 9-pin RS232 interface and the PC-Direct feature transfer weighing data straight into spreadsheets or documents. Thirteen built-in application programs and 13 languages are included, covering weighing, dosing, counting, percentage weighing, density determination, statistics, checkweighing and pipette smart test.
All models have a Ø 90 mm weighing pan and a weighing chamber 240 mm high, and measure 219 × 317 × 345 mm (W × D × H). Our team can help you choose the right model and accessories.
