Minimalist Science Toolbar Icons — SVG & PNG Set

10 Modern Science Toolbar Icons for UI Designers

Use: Zoom/inspect, analyze, detailed view.
Design tips: Simplify the silhouette; keep eyepiece, stage, and objective recognizable at 16–24 px. Use a single accent color for the lens highlight.

Use: Experiments, samples, lab mode.
Design tips: Slight tilt adds dynamism. Represent liquid with a clipped shape and a subtle gradient or two-tone fill to show level.

Use: Chemistry, molecular data, connections.
Design tips: Use 3–4 orbiting nodes around a central nucleus. Keep stroke weight consistent; avoid overlapping lines at small sizes by slightly offsetting or removing thin orbit lines.

Use: Reagents, mixing, reaction processes.
Design tips: Round-bottom or Erlenmeyer silhouette reads well. Show bubbles or liquid fill with high-contrast shapes instead of fine details.

Use: Genetics, bioinformatics, sequencing.
Design tips: Use two parallel curved ribbons with minimal crossbars; at tiny sizes, reduce to a simple twist or single strand motif.

Use: Transfer, add/remove sample, precise input.
Design tips: Angle the pipette with a droplet at tip for clarity. Keep the bulb and tip proportionate so it remains identifiable at small scales.

Use: Cultures, growth, colonies, samples.
Design tips: Use concentric circles and a few rounded dots to suggest colonies. A slightly open lid or small shadow can distinguish it from a simple disc.

Use: Temperature, incubator, conditions.
Design tips: Use a classic bulb-and-tube shape with a short scale line or a small filled level. Avoid tiny tick marks; instead use a single contrasting fill level.

Use: Simulation, processing, compute science tasks.
Design tips: Combine a partial gear outline with a small atom/molecule inside. Keep both motifs simplified so neither overwhelms the other.

Use: Results, analytics, experiment outcomes.
Design tips: Use a small bar or line chart with a highlighted peak point. Ensure gridlines are omitted at small sizes; rely on a single bold stroke for the sparkline.

Size & Grid: Design on a multiple-of-4 px grid (16/24/32 px); test icons at 16 px.
Stroke & Weight: Keep stroke consistent across the set; prefer 1.5–2 px for medium sizes.
Contrast & Fills: Use simple two-tone fills or single-color strokes with one accent color for interactive states.
Metaphor Consistency: Keep visual metaphors consistent (e.g., always tilt pipette, always circular nodes for molecules).
Accessibility: Ensure icon meaning is redundant with text labels or tooltips; provide distinct hover/focus states.

If you want, I can create SVG code for any of these icons sized for 24 px.
