- Label and document concentrations, solvent, date, operator, and storage conditions

- Flag solubility issues, discrepancies, or labeling/inventory mismatches

### Receiving, staging & inventory (automation-ready)

- Receive shipments, verify contents vs packing slips/POs, and triage issues (damage, missing items)

- Log inventory and assign locations so materials are retrievable fast and consistently

- Put away chemicals and supplies in correct storage (ambient/fridge/freezer/flammables/corrosives)

- Stage supplies/consumables (vials, tubes, tips, labels, solvents, PPE)

### General lab ops support
