Opentrons Heater-Shaker Module - temperature control (37-95°C) with orbital mixing (200-3000 rpm) for cell culture, enzymatic reactions, and sample preparation requiring simultaneous heating and agitation.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Opentrons Heater-Shaker Module ## Overview The **Heater-Shaker Module** combines precise temperature control (37-95°C) with orbital shaking (200-3000 rpm) for automated protocols requiring simultaneous heating and mixing. Ideal for cell culture incubation, enzymatic reactions, bacterial transformations, and any workflow needing temperature-controlled agitation. **Core value:** Automate temperature-sensitive mixing protocols with reproducible timing and conditions. Replace manual incubator transfers with on-deck temperature control. ## When to Use Use the Heater-Shaker skill when: - Performing enzymatic reactions requiring temperature control and mixing - Incubating cell cultures or bacterial transformations - Conducting ELISA washing steps with temperature control - Running temperature-sensitive binding or hybridization reactions - Protocols requiring precise timing of heating + mixing cycles - Resuspending beads or particles with controlled agitation **Don't use when:** - Only temperature control needed (use Temperature Module instead) - Only mixing needed (consider manual shaking or alternative approaches) - Temperature outside 37-95°C range (or <1.5°C above ambient) …

How to install
mdr add jkitchin/knowhow/opentrons-heater-shaker@sha256:99f16d32b8acd470The line at the top of this page pins the label git:20260307.3e74b2f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
