Ohaus Precision Analytical Balance EXP12202 with 12,200 g Capacity and 0.01 g Readability
Product Description
The Ohaus Precision Balance EXP12202 is a modular, high-capacity analytical balance designed for diverse laboratory weighing applications including basic weighing, parts counting, formulation, and density determination—essential in bioprocessing and molecular diagnostics workflows. It features a 12,200 g maximum capacity with a precision readability of 0.01 g, supporting precise quantitative analyses crucial for biotechnology and clinical diagnostics.
Key technical specifications and features include:
- Weighing pan size: 201 mm x 178 mm stainless steel (SST 316) ensures chemical resistance and durability for typical lab environments.
- Internal Calibration: AutoCal™ automatic calibration for consistent precision compliance.
- Display: 7-inch TFT 16.7M color touchscreen with glass overlay offers intuitive user control and visibility, improving workflow in live-cell imaging and biomanufacturing labs.
- Communication ports: USB Host (Type A) x 2, USB Device (Type B & C), Ethernet RJ45, RS232, with optional Wi-Fi and Bluetooth dongle support for seamless data transfer and integration into laboratory information management systems (LIMS).
- Construction: Robust metal housing with motorized leveling system, anti-static glass draftshield, automatic safety doors, built-in ionizer, and sample spotlight (for 1 mg models), meeting strict requirements for molecular cloning and synthetic biology research.
- Weighing modes: Includes specialized modes such as percent weighing, check counting, totalization, peak hold, and SQC (statistical quality control), enabling precise measurement control in biopharmaceutical production pipelines.
- User management: 4-level user access with internal log capacity for 100,000 entries enhances traceability and security in regulated environments.
- Environmental compatibility: Operates reliably within 10°C - 30°C, 80% RH non-condensing settings, suitable for typical lab conditions involving live-cell imaging and fluorescence analysis.
This precision balance is widely adopted in synthetic biology research and molecular biology due to its accuracy and comprehensive connectivity, making it integral for gene editing protocols, biomanufacturing quality control, and biomedical engineering applications. The inclusion of multiple weight units, fast stabilization time (1 s), and repeatability specifications (0.01 g) ensure rigorous compliance with industry standards for analytical measurement.
Ideal for laboratory professionals and researchers requiring a reliable weighing solution supporting critical workflows, the Ohaus EXP12202 balance provides dependable performance across various scientific disciplines including biotechnology, clinical diagnostics, and research requiring advanced lab weighing technologies.
