Quintix Semi-Micro Balance
The Sartorius Quintix semi-micro balances give 0.01 mg (five-decimal-place) readability in three models: QUINTIX35-1S (30 g), QUINTIX65-1S (60 g) and the dual-range QUINTIX125D-1S (60 g at 0.01 mg and 120 g at 0.1 mg). A touchscreen, the Start Assistant, isoCAL automatic internal adjustment, a built-in temperature management system and the One-Touch draft shield make precise weighing quick and easy in everyday laboratory work.
Overview
The Sartorius Quintix Semi-Micro Balances are standard laboratory balances with 0.01 mg readability for everyday precision weighing in research, education, chemical and quality control laboratories. Three models cover the range:
QUINTIX35-1S: capacity 30 g, readability 0.01 mg.
QUINTIX65-1S: capacity 60 g, readability 0.01 mg.
QUINTIX125D-1S (dual-range): 60 g with 0.01 mg readability, and up to 120 g with 0.1 mg readability.
Easy to use from day one
The Start Assistant and the SmartTouch user interface let you operate the balance straight away. The convenient operating design with its easy-to-understand menu and the ergonomic balance design have already won several awards. Built-in standard applications guide you in simple steps through special lab tasks.
Accurate in everyday conditions
A built-in temperature management system keeps the climate inside the weighing chamber stable.
The One-Touch draft shield is easy to use and compensates for even the slightest ambient effects.
isoCAL adjusts the balance automatically, controlled by temperature and time, so results stay reliable.
The draft shield can be taken apart in a few steps and the rimmed base plate removed completely, which makes cleaning and preventing cross-contamination easy.
Simple data transfer
Connect the balance to a computer or lab printer through the mini USB interface port with Plug & Play. The PC-Direct feature sends results to a computer without additional software. A tamper-proof supervisor lock protects the system settings from unintentional changes.
Performance and accessories
Typical repeatability is 0.03 mg (0.03 mg and 0.07 mg on the dual-range model) and typical stabilization time is 4 seconds or less (4 seconds or less and 1.5 seconds or less on the dual-range model). Sartorius thermal printers for GxP printouts and an external rechargeable battery pack are available as accessories.
All three models have a Ø 80 mm weighing pan and a weighing chamber 218 mm high, and measure 218 × 376 × 316 mm (W × D × H). Our team can help you choose the right model and accessories.
