Quintix Pro Analytical Balance
The Sartorius Quintix Pro analytical balances weigh 120 g, 220 g or 320 g with 0.1 mg readability and a typical stabilization time of 1.5 seconds or less. A large 7-inch full-touch graphic display, isoCAL internal adjustment, LevelControl with real-time level support or motorized automatic levelling, user management and 15 built-in applications make this premium standard balance universal, from routine weighing to regulated work and cleanrooms.
Overview
The Sartorius Quintix Pro Analytical Balances are standard laboratory balances with premium features: a large, 7-inch, high-resolution full-touch graphic display, internal adjustment with isoCAL and a choice between real-time level support and fully motorized levelling. They read to 0.1 mg and are designed to be a true universal balance for research, quality control, pharma and education.
Six models
QTX324IRU-1S / QTX324IMU-1S: capacity 320 g.
QTX224IRU-1S / QTX224IMU-1S: capacity 220 g.
QTX124IRU-1S / QTX124IMU-1S: capacity 120 g.
In the model code, I means internal adjustment (isoCAL), R means real-time level support, M means motorized automatic level feet and U means a manual glass draft shield.
Correct levelling, every time
A level indicator shows at a glance whether the balance is level. The LevelControl function monitors the level status continuously in real time; if it detects a tilt it alerts you, temporarily blocks data transfer to a printer or computer and guides you through levelling. The motorized models level themselves fully automatically at the push of a button.
Easy to use and fully documented
A startup assistant, a built-in interactive manual and 15 languages make setup and daily use quick.
User management assigns individual roles and passcode protection, and the Device-Log records calibration, levelling and settings changes with date and time stamps.
Fifteen integrated applications cover common tasks such as dosing, counting, percentage weighing, density determination, statistics, checkweighing and pipette smart check.
Connectivity and robustness
Three USB Type-C interfaces, a 9-pin RS232 interface and an Ethernet interface connect printers, computers, USB sticks and databases. Parts made of PBT, glass and stainless steel resist chemicals and support routine cleaning, and the balance is tested for use in cleanrooms of grade A and B and in special environments such as vacuum, argon and nitrogen.
All models have a Ø 90 mm weighing pan and a weighing chamber 240 mm high, and measure 220 × 377 × 346 mm (W × D × H). Our team can help you choose between level support and motorized levelling and the right accessories.

Key features
- 7-inch full-touch graphic display A large, high-resolution display with a modern interface, a status center and a built-in interactive manual.
- LevelControl: level support or motorized levelling Real-time level monitoring with alerts that block data transfer on tilt (R models), or motorized feet that level the balance automatically (M models).
- isoCAL and Device-Log Temperature- and time-controlled internal adjustment, with every calibration, levelling and settings change recorded with date and time.
- User management and safety levels Individual user roles with passcode protection and high, standard or low monitoring levels for secure data transfer.
- 15 applications and rich connectivity Fifteen built-in applications, three USB Type-C ports, RS232 and Ethernet for printers, PCs and databases.
Key advantages
- Always correctly levelled LevelControl and the optional motorized feet protect your measurements from tilt errors.
- Fast, stable weighing Typical stabilization time of 1.5 seconds or less and typical measurement time of 2 seconds or less.
- Suited to special environments Tested for cleanrooms of grade A and B, vacuum, argon and nitrogen, with chemical-resistant surfaces that are easy to clean.
- Flexible and efficient The semi-automatic filter adaption (AFA) adapts the balance to your environment with one click, and power-saving modes and a start timer reduce energy use.
- Quick to learn The startup assistant, 15 languages and the built-in manual help new users start right away.
