Secura Analytical Balance
The Sartorius Secura 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. isoCAL internal adjustment with a Cal Audit Trail, SQmin USP monitoring, a password-protected menu with safety levels and a touchscreen with alphanumeric input make them dependable standard balances for regulated laboratories.
Overview
The Sartorius Secura Analytical Balances are standard laboratory balances with 0.1 mg readability, built for regulated areas such as pharma and quality control where results must be traceable. Three models cover the range:
SECURA124-1S: capacity 120 g.
SECURA224-1S: capacity 220 g.
SECURA324-1S: capacity 320 g.
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, giving a fully traceable audit trail.
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 with alphanumeric input makes entering sample IDs simple. The Start Assistant and SmartTouch interface let staff weigh straight away, and the mini USB port with Plug & Play and PC-Direct sends results to a computer or lab printer without additional software. Built-in applications turn special lab tasks into guided routines.
Documentation and accessories
Sample and batch identification, monitored data transfer and the PC-Direct feature support reliable records: results can be transferred, evaluated, saved and documented in line with legal requirements just by using Plug & Play technology, without extra software or complicated settings. Sartorius thermal printers for GxP printouts on standard paper or label rolls and an external rechargeable battery pack are available as accessories.
