Every building block below stands for one step of the experiment — what was weighed in, observed, changed, separated or measured. Out of the blocks this page writes a coherent text at the end: the log of the experiment, step by step, in whole sentences. The rail on the left adds a block; the finished example in it shows what the result looks like.
The entries stay in the browser of this machine and are still there after a reload. Nothing leaves this machine on its own: a record reaches the server only when the upload is pressed, and the ZIP export writes the work to a file of your own at any time.
Both fields have to be filled before an entry can be made. They belong to the record and travel in the data ZIP; every entry below is logged with the initials that made it.
Required: the experiment name heads the file name of every local save, the version tells two runs of the same experiment apart.
These entries matter for one thing only: storing the record on the server. Whoever works locally may leave them empty — the protocol can be exported into a ZIP file on your own machine at any time and read back from it.
A template holds one filled subform under a name of its own. It is saved at the block itself, through the gear; here whole sets of them are exchanged and thinned out.
The browser keeps several protocols side by side. The one on the screen is saved continuously; any other one can be loaded over it or deleted. A protocol that is still open in another tab writes itself back after a deletion.

Empties the protocol on the screen together with its head entries. Other protocols, templates and materials stay.
All data in this browser
Deletes every protocol, every template for subforms, the material stock and the stored editors from this browser. A warning comes first; afterwards the page reloads.
Settings and cookies
Resets the bright/dark display, the start view of the subforms and the state of the menu, and deletes the cookies of this page. Protocols, templates and materials stay.

The blocks are locked. Name the initials and the person responsible in the head of the form first — an entry that nobody answers for is worse than a missing one.

You may enter a unit — "0.2 kg", "3.5 oz", "12 cm^3", "1 pt". It is converted into grams resp. millilitres as soon as you leave the field; without a unit the entry counts as grams resp. millilitres. SI prefixes (k, m, µ, …) and the Anglo-Saxon measures are understood; write an exponent with a caret, as in cm^3.
Note: technique and stirrer specification are not shown in the pictogram.
These conditions describe the addition or removal of the substance — they are recorded separately from the observation and the change.
No word belongs to this narrowing
Activities ticked. Usually few of them apply — and some exclude one another. The schematic draws the symbols in one row and becomes hard to read from about twenty on.
Note: the name of the intensive property is not shown in the image above. There the unit has to be enough.
These conditions describe the situation in the reactor, respectively during the addition to the reactor.
The entries are not shown in the picture of this separation. They can help to make the record easier to follow.
Note: the name of the extensive property is not shown in the image above. The unit has to be enough.
Important: For a meaningful characterisation, enter the Rf value (TLC/paper) or the Rt value (LC/GC).
These conditions were maintained during the chromatography.
These conditions describe how the characterised substance is stored — not a working step.
Every device belongs to exactly one category.

These conditions describe the room the run stood in — not the reactor inside it.
