Ohaus Precision Analytical Balance EXP623N/AD with AutoCal and Touchscreen
Product Description
The Ohaus Precision Balance EXP623N/AD (31059185) is a high-performance analytical balance engineered for advanced laboratory weighing applications, including basic weighing, parts counting, check counting, percent weighing, dynamic weighing, totalization, formulation, and density determination. Widely adopted in biotechnology and molecular diagnostics research, it supports critical workflows such as pipette adjustment, flow rate control, and statistical quality control (SQC).
Key technical features include:
- Maximum capacity of 620 g with a precision readability of 1 mg, ideal for sensitive bioprocessing and synthetic biology protocols requiring reliable weight data.
- 7-inch TFT 16.7M color touchscreen display with glass overlay offers intuitive, clear user interaction.
- AutoCal™ internal automatic calibration assures consistent accuracy essential in biomanufacturing environments.
- Modular metal base and SST 316 stainless steel weighing pan ensure durability alongside an anti-static glass draftshield to minimize environmental fluctuations.
- Integrated motorized leveling, built-in ionizer, and sample spotlight enhance precision in live-cell imaging sample preparations and molecular cloning workflows.
- Safety-enhanced automatic anti-pinch doors with touchless sensors improve operational security in sterile laboratory settings.
- Extensive communication interfaces: USB Host (Type A) x 2, USB Device (Type B & C), Ethernet (RJ45), RS232, with optional WiFi and Bluetooth dongle support for seamless data transfer and connectivity in clinical diagnostics and biomanufacturing data management.
- Supports multiple units including milligrams, grams, ounces, carats, and more, facilitating versatility across interdisciplinary research and quality control domains.
- Compliance with NTEP certification for legal-for-trade applications ensures suitability for regulated environments.
This precision balance is essential for laboratories engaged in biotechnology, molecular biology, synthetic biology, and pharmaceutical research, providing reproducible weighing results fundamental for bioprocessing, gene editing, and molecular diagnostics workflows. Its combination of advanced weighing functions and connectivity options makes it popular among scientists requiring reliable analytical balances for demanding research and quality assurance tasks.
