About Secura Semi-Micro
The Sartorius Secura Semi-Micro Balances are standard laboratory balances with five-decimal-place readability (0.01 mg), built for regulated areas such as pharma and quality control. Two models cover the range:
SECURA125-1S: single range, capacity 120 g, readability 0.01 mg.
SECURA225D-1S (dual-range): 120 g with 0.01 mg readability, and up to 220 g with 0.1 mg readability.
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.
The draft shield can be taken apart in a few steps and the rimmed base plate removed completely, and the plate is designed to catch all spills, which makes cleaning and preventing cross-contamination easy.
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 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.
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.
