Spectrophotometer Embedded App

Modernizing embedded UX for scientific workflows and touchscreen lab instrumentation

Overview

As a specialized UI/UX design agency focused on complex and scientific systems, we partnered with Thermo Fisher Scientific to redesign the embedded interface for a laboratory-grade spectrophotometer. This redesign modernized the UI, improved usability for both technicians and researchers, and introduced consistent workflows aligned with laboratory best practices. The embedded app needed to support daily use, specialized test protocols, and operate within strict hardware constraints—while delivering clarity, accuracy, and compliance in lab settings.. Our goal was to modernize the UI, improve usability for both lab technicians and researchers, and integrate consistent workflows that align with laboratory best practices. The redesign needed to support both everyday use and highly specialized test setups, all within the constraints of an embedded system.

Challenges

The legacy UI was visually dated and difficult to navigate, leading to usability issues and inefficiencies in testing procedures. Users found it hard to access key features quickly, and the interface lacked guidance for newer lab staff. Additionally, the application had to support touchscreen interaction within a constrained hardware environment, and remain familiar to existing device users without compromising improvements.

Our Approach

We conducted user interviews with lab technicians, researchers, and product stakeholders to identify task friction, workflow inconsistencies, and interface gaps. We analyzed spectrophotometry protocols and reviewed legacy usage logs to inform decision-making. Our process included:

Custom-Designed Icons for Intuitive Interaction

We created a tailored icon library optimized for lab environments—visually distinct, high-contrast, and easy to interpret at a glance. These icons ensured quick access to frequently used tools, even when users wore gloves or operated the touchscreen under less-than-ideal lighting.

Streamlined Navigation for Embedded Systems

We restructured the navigation to support streamlined task flows. The new design prioritizes common lab procedures and enables technicians to move quickly between setup, calibration, and testing steps without unnecessary taps or nested menus.

Maximizing Data Visibility

The interface presents results with clarity and hierarchy—giving prominence to critical measurements, while maintaining access to raw data and reference markers. Visualizations were enhanced with color, scale, and structure appropriate for embedded display resolution.

Guiding Lab Workflows with Ease

We introduced contextual UI states that guide users through each phase of the workflow. From device calibration to sample analysis, the interface delivers inline prompts, progress indicators, and system feedback, minimizing the chance of error and improving protocol adherence.

Validation & Collaboration

We partnered with Thermo Fisher’s internal teams to test early interactive prototypes. Usability testing sessions included both new lab technicians and seasoned researchers, validating efficiency improvements across diverse roles. Continuous feedback loops between design, QA, and firmware teams ensured the embedded constraints were respected without compromising usability

Results

The Spectrophotometer Embedded App UI combined clarity, simplicity, and custom-designed icons to create a user-friendly interface tailored to a demanding lab environment. By optimizing the design for a small, embedded screen, we ensured that lab professionals could operate the spectrophotometer efficiently, reducing errors and improving productivity.

Improved Usability

Task completion became faster and more consistent, even among less experienced users, thanks to clearer affordances and reduced screen complexity.

Embedded UI Modernization

The new interface introduced consistent visual language, iconography, and interaction standards across the device—enabling faster onboarding and future firmware extensibility.

Better Workflow Compliance

In-app guidance matched lab protocol steps, reducing human error and improving adherence to institutional standards.

Data Confidence

Clear presentation of results, including contextual markers and trend indicators, enabled faster interpretation and better lab decision-making.

Successful Technical Integration

Final implementation was verified across hardware variants, touchscreen calibrations, and display densities—ensuring fidelity and functionality in real-world use.

Positive Internal Reception

Product owners and support staff noted fewer support tickets related to navigation and usage confusion post-deployment.

Embedded UI Modernization

Clear, consistent, touch-optimized interface that works within hardware constraints

Data Confidence

Users can now see results clearly, including trends and exceptions, aiding fast decision-making
