OHAUS Explorer Plus™ Semi-Micro EXP Analytical Balance
Manufactured by Ohaus
Ideal for regulated labs, pharmaceutical, biotech, and advanced research and development applications, the OHAUS Explorer Plus™ Semi-Micro EXP Analytical Weighing Balance offers precision down to 0.1mg.
With motorised levelling that automatically levels the balance for you, a built-in ioniser, and a four-level user system, it includes extra automation, compliance, and data traceability features compared to the Semi-Micro EXR.
Both ISO 9001 calibration or UKAS 17025 calibration are available for this new generation of analytical balances (For UKAS balance calibration, please contact us).
Benefits
- Motorised levelling with a digital bubble, ensuring a smooth and straightforward setup by automatically levelling the balance for you.
- Equipped with three ambient sensors to measure key loadcell factors: temperature, humidity, and air pressure.
- Enhanced automatic draftshield doors operated by IR sensors and soft key offer anti-pinch safety protection, ensuring easy sample access and preventing operator injuries.
- Doors create a draft-free environment for sensitive weighing, helping improve repeatability and speed up stabilisation times.
- Doors have a half-open design for sensitive powder samples that require a longer time to stabilise with airflow.
- Digital weighing components (DWC) offer the advantage of creating self-contained load cell modules.
- Built-in ioniser reduces static electricity in the weighing chamber of the analytical balance for consistent results.
- 7-inch touchscreen display with vibrant colours, an easy-to-clean glass panel, and chemical resistance ensures a clear, durable, and intuitive interface.
- Touchless sensors provide hands-free operation (tare, zero, print) on the terminal, minimising cross-contamination risks and reducing device wear-and-tear.
- Four-level user system, password protection, and 100k internal system log ensures compliance and traceability.
- Optional fingerprint login system available for secure and personalised access.
- Sample spotlight (colour: white) for enhanced visibility and making a ClearView Environment.
- Customisable terminal and draftshield status lights for weighing visually, clearly indicating overload or underload behaviour during the weighing process.
- Lighting system can be customised into rainbow colours (red, pink, yellow, green, cyan, blue, or white).
- Draftshield has an anti-static coating to reduce static electricity around the balance for consistent results.
- Draftshield is easily removable for easy cleaning and long-term care, as well as specific large volume weighing applications.
- Internal calibration systems (automatic, user-triggered, and span calibration options) ensure precise measurements.
- Fast 2-second stabilisation time to boost efficiency.
- Routine repeatability test ensures consistent long-term accuracy and reliability, making it ideal for critical applications such as weighing in regulated environments, where meeting strict uncertainty measurements is paramount.
- Full metal housing provides robust protection for internal components.
- Detachable terminal and base offers flexibility and is suitable for small lab cabinets or fume hoods.
- Out-of-the-box packaging design means no assembly is required, saving you time and effort.
- Apply to 15 weighing applications – large sample profile streamlines your workflow.
- 3000 sample libraries, including Sample ID, Batch ID, Customised Title,….
- Dedicated Sample Dosing Mode for powder sample application.
- Multiple USB ports offer unparalleled flexibility.
- Direct to Excel feature provides a basic yet highly user-friendly option for data transfer.
- Supports HID connection to PC or keyboard without drivers.
- Network Time Protocol (NTP) ensures accurate timekeeping and confirms data traceability to meet pharmaceutical regulations.
- Compatible with SICS command and easy to integrate to LIMS, MES system.
- Label printing function (2 preset templates and 10 customised templates) – Bluetooth printer available as add-on.
- Weighing pan made with lightweight and durable zinc alloy.
- Model EXP225D/AD is Green Lab ACT Ecolabel certified for its sustainable design. This includes reduced shipping weight, sleep mode which offers a 65% reduction in power consumption, and up to 58% of total components made from recycled materials.
Note on Trade Approved (M) Models
For commercial transactions requiring verified weights, AML Instruments offers the Explorer ‘M’ certified models (e.g., EXP125DM/AD). These specialised balances are verified to meet or exceed UK/EU weights and measures regulations, providing Legal-for-Trade Compliance for businesses ranging from jewellery to industrial packaging.
