Quintix Pro Precision Balance
The Sartorius Quintix Pro precision balances weigh from 320 g up to 12,200 g with 1 mg, 10 mg or 100 mg readability and a typical stabilization time of 1.0 second 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 for everyday weighing.
Overview
The Sartorius Quintix Pro Precision 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. Fifteen models cover capacities from 320 g to 12,200 g, each with R (level support) or M (motorized levelling) versions.
1 mg models with draft shield (Ø 120 mm pan, manual glass draft shield)
QTX1503: 1,500 g. QTX1203: 1,200 g. QTX623: 620 g. QTX423: 420 g. QTX323: 320 g.
10 mg models with open pan (182 × 182 mm pan)
QTX6202: 6,200 g. QTX4202: 4,200 g. QTX3202: 3,200 g. QTX2202: 2,200 g. QTX1202: 1,200 g.
100 mg models with open pan (182 × 182 mm pan)
QTX12201: 12,200 g. QTX10201: 10,200 g. QTX8201: 8,200 g. QTX6201: 6,200 g. QTX3201: 3,200 g.
In the model code, I means internal adjustment (isoCAL), R means real-time level support, M means motorized automatic level feet, U means a manual glass draft shield and O means no 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 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. Our team can help you choose the right model, levelling option and accessories.
