SECURA26-1S Micro Balance

The Sartorius Secura micro balance weighs up to 21 g with a readability of 2 µg (0.002 mg) over the entire weighing range, giving six-decimal-place accuracy for the smallest quantities. A built-in temperature management system, the One-Touch draft shield, a titanium weighing pan with two titanium pan draft shield rings and isoCAL internal adjustment make it a dependable standard balance for regulated laboratories.

Overview

The Sartorius Secura26-1S Micro Balance is a standard laboratory micro balance with a capacity of 21 g and a readability of 2 µg (0.002 mg) over the entire weighing range. It is designed for analytical weighing where six decimal places matter, for example weighing small samples, preparing standards and quality control in pharma, chemical and research laboratories.

Built for accurate results 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.
The weighing chamber base plate comes off easily, so cleaning is simple.
A titanium weighing pan and two titanium pan draft shield rings are supplied as standard. The raised rim of the ring supports precise measurements even under a laboratory fume hood with interfering air flow, and titanium is non-magnetic and inert to aggressive substances.

Made for regulated work

isoCAL adjusts the balance automatically, controlled by temperature and time, and the internal Cal Audit Trail documents every calibration and adjustment.
SQmin checks that your sample is within the balance operating range for USP compliance, warns you when the sample is below the minimum net weight and blocks data transfer until it is permissible.
Password-protected menu settings and selectable safety levels (high, standard or low) control who can change what and which data is processed further.

Easy to operate and connect

An interactive touchscreen display with alphanumeric input makes it easy to enter complicated sample IDs, and the Start Assistant and SmartTouch interface let you start weighing straight away. Connect to a computer or lab printer through the mini USB port with Plug & Play and the PC-Direct feature, without additional software.

At a glance

The balance has a Ø 50 mm weighing pan, a weighing chamber 218 mm high and measures 218 × 376 × 316 mm (W × D × H). Typical repeatability is 0.004 mg and typical stabilization time is 6 seconds or less. Our team can help you choose accessories and plan the installation.
