Automatically schedule reconstitution when your peptide shipment arrives

Instead of checking shipment updates and manually adding preparation appointments, automate peptide reconstitution scheduling with a receiving log that creates a calendar event only after laboratory receipt and quality release. This guide connects Google Sheets, Google Apps Script, and Google Calendar without treating a carrier’s delivery notification as permission to reconstitute a research peptide.

Why this matters

A delivered parcel is not a released laboratory material. Receiving staff still need to match the shipment to the order, inspect its condition, identify the lot, and route exceptions through the laboratory’s procedures.

Celonyx Labs sells 99%-pure, third-party-tested research peptides. Those quality signals do not replace your laboratory’s acceptance criteria, solvent selection, or preparation procedure. Celonyx Labs research peptides are best suited to laboratory researchers using documented, research-only workflows.

The workflow below automates calendar administration, not the physical preparation or scientific decision. For your 2026 setup, keep receipt, quality release, and scheduling as separate records. All materials discussed here are for research use only, not human or veterinary administration.

Before you start

• Have a Google account with access to Google Sheets, Apps Script, and Google Calendar. Your organization must permit the script’s requested spreadsheet and calendar permissions.
• Have an approved reconstitution SOP, a receiving record, an assigned researcher, and an agreed preparation window. Choose the window from your protocol and resource availability; this guide supplies no universal preparation duration.
• Resolve the identity gotcha: the time-driven trigger uses its creator’s permissions and calendar. Use the account whose primary calendar should hold these appointments, and restrict who can edit release fields in the sheet.

There is no assumed connection to the store’s order system. Receiving staff enter shipment information into your laboratory sheet; the automation then handles eligible calendar records. A carrier feed, if you have one, remains a separate input rather than a release authority.

Receiving record configuration

Choose the scheduling gate

Use laboratory release as the default gate. The alternatives below describe different administrative workflows, not different peptide preparation methods.

Use a quality-release appointment for the actual reconstitution schedule. If your team wants an earlier notification, label it as a receiving task rather than a preparation appointment.

Build the sheet

1. Create a Google spreadsheet and name one tab Receiving.
2. Enter the following headers in the first row, in exactly this order: Order ID, Lot ID, Receipt status, QC status, SOP reference, Assigned researcher, Start, End, Event ID, Sync status.
3. Use Received only after your receiving procedure is complete. Use Released only after authorized quality review. Use Hold or Quarantined for material that must not remain scheduled.
4. Enter actual spreadsheet date-time values in Start and End, not text descriptions. Record the approved SOP reference and researcher’s name.
5. Leave Event ID and Sync status empty. The script owns these columns; staff should not edit them.

The column names above are fields you create, not built-in vendor settings. Keep one row per lot and preparation window. If one shipment contains several lots, give each lot its own row.

Expected result: each row contains enough information to create one traceable appointment, while unreleased material remains unscheduled.

Calendar automation configuration

Set the time zone and script

1. In Google Sheets, open File, then Settings, and set Time zone to the laboratory’s scheduling time zone.
2. Open Extensions, then Apps Script. In Project Settings, set Time zone to the same zone. Check the destination calendar’s time zone as well.
3. Replace the editor’s starter code with the script below and save the project.
4. Select syncReconstitution in the function selector and choose Run. Review and approve the requested permissions with the intended calendar account.

Use matching time zones during your 2026 configuration review. The script reads the sheet’s actual dates; it does not interpret phrases such as next afternoon or after delivery.

function syncReconstitution() {
  const lock = LockService.getScriptLock();
  if (!lock.tryLock(10000)) return;

  try {
    const sheet = SpreadsheetApp.getActiveSpreadsheet()
      .getSheetByName('Receiving');
    if (!sheet) throw new Error('Receiving tab not found');
    if (sheet.getLastRow() < 2) return;

    const calendar = CalendarApp.getDefaultCalendar();
    const rows = sheet.getRange(2, 1,
      sheet.getLastRow() - 1, 10).getValues();

    rows.forEach((row, index) => {
      const [order, lot, receipt, qc, sop, researcher,
        start, end, eventId] = row;
      const rowNumber = index + 2;
      const statusCell = sheet.getRange(rowNumber, 10);
      if (!order && !lot && !eventId) return;

      try {
        const event = eventId
          ? calendar.getEventById(String(eventId)) : null;
        if (eventId && !event) {
          throw new Error('Stored event not found; review manually');
        }

        if (qc === 'Hold' || qc === 'Quarantined') {
          if (event) event.deleteEvent();
          sheet.getRange(rowNumber, 9).clearContent();
          statusCell.setValue('Blocked: ' + qc);
          return;
        }

        if (receipt !== 'Received' || qc !== 'Released') {
          statusCell.setValue(event
            ? 'Review existing appointment: gate changed'
            : 'Waiting for receipt and release');
          return;
        }

        if (!order || !lot || !sop || !researcher ||
            !(start instanceof Date) ||
            !(end instanceof Date) ||
            !Number.isFinite(start.getTime()) ||
            !Number.isFinite(end.getTime()) || end <= start) {
          throw new Error('Complete fields and valid Start/End required');
        }

        const title = 'Research reconstitution | ' + order + ' | ' + lot;
        const description = 'SOP: ' + sop + '\nAssigned researcher: ' +
          researcher + '\nFor research use only.';

        if (event) {
          event.setTime(start, end);
          event.setTitle(title);
          event.setDescription(description);
        } else {
          const created = calendar.createEvent(title, start, end,
            {description: description});
          sheet.getRange(rowNumber, 9).setValue(created.getId());
        }
        statusCell.setValue('Scheduled');
      } catch (error) {
        statusCell.setValue('Error: ' + error.message);
      }
    });
  } finally {
    lock.releaseLock();
  }
}

The script does not invite the assigned researcher, inspect calendar conflicts, select a solvent, or calculate concentration. Assigned researcher appears in the event description; it is not an attendee field.

Expected result: an eligible row creates an event on the executing account’s primary calendar, and its event ID appears in the sheet.

Add the recurring trigger

1. In Apps Script, open Triggers, then Add Trigger.
2. Under Choose which function to run, select syncReconstitution.
3. Under Select event source, select Time-driven. Under Select type of time based trigger, select Minutes timer.
4. Under Select minute interval, choose Every 15 minutes, then select Save.

The 15-minute interval is a configuration choice, not a guaranteed response time. Apps Script execution timing, permissions, and service quotas still apply. Keep receiving and release notifications separate if your laboratory requires immediate escalation.

Expected result: the script checks the sheet repeatedly without staff opening the editor. Review Executions for failed runs rather than assuming a saved trigger is working.

Release checks and workflow validation

The workflow has three distinct checkpoints: Receipt check, Release gate, and Calendar event. Receiving establishes what arrived, release establishes whether preparation is authorized, and the calendar records when the assigned researcher plans to work.

1. Create 2 test rows with clearly marked test identifiers. Give both valid date-time values and SOP references; set one to Received and Released, and leave the other unreleased.
2. Use a 30-minute calendar window for the test appointment only. This tests scheduling mechanics; it is not a recommended reconstitution duration.
3. Run syncReconstitution. Confirm that only the released row creates an appointment and receives an Event ID.
4. Run it again. Confirm that the same event ID remains and no duplicate appointment appears.
5. Change the released row to Hold and run again. Confirm that the appointment disappears and the row reports the block.

For a 2026 acceptance check, also test a missing SOP reference, an end time before the start time, and a stored event ID whose event has been deleted. Each should produce a visible error rather than an unreviewed replacement appointment.

Expected result: your test demonstrates creation, repeat-run behavior, blocking, and error reporting before you use live records.

Reschedule when the preparation window changes

Updating an existing appointment is the adjacent workflow this script already supports. Keep the stored event ID, change Start and End, and leave the receipt and release fields eligible. The next successful run updates the original calendar event.

Edit the receiving sheet, not the calendar, when changing a scheduled window. Direct calendar edits are overwritten by the next successful synchronization because the sheet is the source of scheduling information.

If quality review changes, use Hold or Quarantined to remove the event. Other changes away from Received or Released produce a review warning but do not automatically delete an existing appointment. Investigate that warning and apply the appropriate laboratory decision.

This distinction prevents an unexpected status spelling from silently deleting work. It also means your 2026 operating procedure must assign someone to review warnings, not just errors.

Do not reuse a completed row for a new preparation. Archive it under your record-retention procedure and create a new row for the new lot or window; otherwise, the script updates the earlier event.

Troubleshooting

• Delivered shipment, but no event: carrier delivery does not satisfy the gate. Complete physical receipt and authorized release, then enter the exact statuses Received and Released.
• An error requests valid Start/End values: check that both cells contain actual date-time values and that the end follows the start. Text that looks like a date is not enough.
• The event appears on the wrong calendar: check which account authorized the script and created the trigger. Remove the incorrect trigger and recreate it under the intended account; review misplaced events manually.
• Stored event not found: inspect the destination calendar and row history. Restore the event if appropriate, or clear the stored ID only after confirming that a replacement will not duplicate an existing appointment.
• Duplicate events appear: check for copied rows, additional scripts, or cleared event IDs. The lock prevents overlapping runs of this script, but it cannot prevent another project from creating the same appointment. Keep one scheduling owner.

A rare failure between event creation and saving its ID can also leave an unlinked appointment. Before rerunning an affected row, search the calendar by order and lot. The workflow requires exception review; it is not a transaction-safe inventory system.

Customize your workflow

Start by connecting the receiving record to your laboratory’s evidence trail. Link the SOP reference to its controlled document, retain the relevant lot documentation, and define who can change release status. Restrict spreadsheet sharing and avoid putting confidential experimental details in broadly shared calendar descriptions.

For shipments requiring condition review, connect the receiving process to your peptide shipment cold-chain monitoring workflow. Environmental observations belong in the acceptance decision, not in an automatic rule that assumes every delivered parcel is acceptable.

For Celonyx Labs research peptide orders, retain order and lot identifiers alongside your laboratory’s decisions. The scheduling script does not retrieve supplier documentation or prove that a particular lot meets your experiment’s requirements.

Before expanding your 2026 workflow, assign an owner for failed executions, gate-change warnings, and orphaned events. Add automatic slot selection or researcher invitations only after validating those features separately. Reliable exception handling comes before additional automation.

FAQ

One last thing

Do not schedule reconstitution merely because automation makes it easy. Schedule it when the approved experiment requires preparation; shipment receipt can instead lead to documented storage under the applicable SOP.

Celonyx Labs supplies research peptides, while your laboratory determines acceptance and experimental handling. Your final 2026 review should confirm that the calendar event represents approved work—not an instruction generated solely from delivery status. For research use only.
