Secura Precision Balance
The Sartorius Secura precision balances weigh from 210 g up to 1,100 g: five milligram models with 1 mg readability and a draft shield, and two precision models with 10 mg readability and an open pan. 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 Precision Balances are standard laboratory balances for regulated areas such as pharma and quality control where results must be traceable. Two groups cover the range:
Milligram balances, 1 mg readability, with draft shield: SECURA213-1S (210 g), SECURA313-1S (310 g), SECURA513-1S (510 g), SECURA613-1S (610 g) and SECURA1103-1S (1,100 g).
Precision balances, 10 mg readability, open pan: SECURA612-1S (610 g) and SECURA1102-1S (1,100 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. Sample and batch identification and monitored data transfer support reliable records, and Sartorius thermal printers for GxP printouts and an external rechargeable battery pack are available as accessories.
Weighing details
The milligram models have a typical repeatability of 1 mg, a typical stabilization time of 1.0 second or less, a Ø 120 mm weighing pan and a weighing chamber 209 mm high, and measure 218 × 359 × 319 mm (W × D × H). The precision models have a typical repeatability of 10 mg, a typical stabilization time of 0.9 seconds or less and a Ø 180 mm pan on an open weighing platform, and measure 218 × 359 × 94 mm. Our team can help you choose the right model and accessories.
