Details

The RDS-3500 FLEX lateral flow reader is designed to adapt to different testing workflows without requiring separate instruments. A single button press rotates the display 180 degrees, allowing the device to transition instantly between benchtop, hands-free operation and handheld use.

In handheld mode, the RDS-3500 FLEX is powered by a rechargeable lithium-ion battery that provides hours of continuous operation, enabling testing without connection to an external power supply. The reader is ergonomically designed to fit comfortably in the palm of the hand, supporting use in mobile, field, or on-site testing environments. Test results are viewable and stored directly on the device, eliminating the need for a separate computer during operation. When physical documentation is required at the point of testing, the reader can be connected directly to a printer. The device is also designed for easy cleaning, supporting routine use in varied testing conditions.

For benchtop use, the RDS-3500 FLEX is supplied with a stand that enables hands-free, desktop testing. Automated measurement features allow users to initiate tests and perform other tasks while results are processed, supporting efficient laboratory and manufacturing workflows. When connected to Wi-Fi, test results can be automatically sent to the cloud for centralized access and record management. The system supports both visible and fluorescent detection and includes advanced thermal control capabilities to help maintain consistent measurement conditions. 

By combining handheld portability with automated benchtop functionality in a single system, the RDS-3500 FLEX lateral flow reader enables teams to standardize testing across environments without compromising performance. This flexible design supports consistent, quantitative analysis wherever rapid testing is required.

FAQ

Frequently Asked Questions and Answers

The RDS-3500 FLEX lateral flow reader supports test strips with up to five test lines. Standard settings are optimized for red-colored lines. If your assay uses a different line color or requires fluorescent detection, the system can be configured to support those requirements.

Yes. The RDS-3500 FLEX lateral flow reader can be configured with a custom cassette insert or strip holder and is compatible with housings up to 44 mm wide × 44 mm deep, allowing flexibility across different assay formats.

No. The Data Manager is not required to operate the reader or view results. All test results are stored and viewable directly on the RDS-3500 FLEX device. The Data Manager is used for viewing, exporting, and managing results when cloud connectivity or centralized data access is needed.

Yes. Interface branding is available with a minimum purchase of 10 lateral flow readers. Additional branding options may be available for larger-volume orders. Please contact our team for details.

Yes. The RDS-3500 FLEX lateral flow reader includes a one-year parts and labor warranty.

Yes. Volume discounts are available. Please contact our team to discuss pricing options based on order quantity.
