The Sartorius CPA423S has been discontinued and no longer in production as of May 2013. The CPA423 was discontinued since the microprocessor used in the CPA is obsolete and the balance was not ROHS Compliant. To sum it up best the CPA was retired due to old technology. Sartorius CPA line was phased-out and replaced with the new Secura 513-1S or Quintix 513-1S. The Secura and Quintix balances are an entirely new cutting edge design offering superior weighing technology over the CPA423S. Buyer beware if someone tries to sell you a used or left over CPA since in our opinion they are not worth buying especially when there is the new Sartorius Entris423-1S that will cost you about $1100. We have no remaining stock on the CPA423S and all information displayed herein is for archival and support purposes only.
If you're looking for accurate, dependable and quality weighing that will last
many years the Sartorius line is the only choice. Sartorius relentless
quest to perfection and innovation never stops. Unique designs like the
triangular chamber doors on the CPA423S that can easily be removed for cleaning
All Sartorius CPA Series balances come standard with isoCAL motorized internal calibration.
The new Sartorius CP generation of the field-proven Sartorius Competence series of laboratory balances, whose reliability has won over many users in their daily lab procedures, sets the standards yet again in technology, quality and features.
The combination of high-performance technological features in every CPA precision balance with a rugged, built-to-last design ensures the best possible accuracy in continuous laboratory use.
Every CPA precision balance has exactly the performance features that are required for fast and professional processing of weighing tasks, including four digital filter levels for adapting the balance to the place of installation, for example, and an RS-232C interface port for communication with a computer.
Built-in, user-friendly application programs provide valuable support for advanced requirements, such as weighing in percent, net-total formulation, animal weighing, mass unit conversion and counting.
All Sartorius CPA Milligram Balances feature:
Built-in, motorized calibration weight ensures the highest accuracy at the press of a key
isoCAL calibration and adjustment function; facilitates regular, fully automatic calibration and adjustment to ensure the consistently high accuracy of the balance
Innovative, patented monolithic weigh cell for outstanding performance
Large backlit display (digit size: 16 mm); read off results without error regardless of ambient lighting conditions
ISO/GLP-compliant documentation (in combination with the optional Sartorius data printer or a PC)
Award winning design and technology is built into every Sartorius balance and
the Sartorius CPA423S (420 x 1mg) packs a punch. Sartorius laboratory balances
deliver high sensitivity, yet it's rugged, durable and delivers consistently
accurate results in the shortest time. The Sartorius CPA Milligram
Balances features triangular weighing pan adding 27% more surface space for
samples compared to previous models, large LCD with backlit display and the
exclusive Sartorius Monolithic Weighing Cell. The triangular chamber doors
can easily be removed for cleaning as needed.
Sartorius has been discontinued production of CPA423S.
The closest replacement for the CPA423 would be the Secura 513-1S or Quintix 513-1S. We have no remaining stock on the CPA423. All information displayed herein is for archival and support purposes only.
