Aliquot History Versus Stock Catalogs: Two Lab Software Jobs
Sample-tracking software versus lab inventory software is two jobs, not one platform slogan. Sample-tracking software follows an aliquot through people and time. Inventory software catalogs unopened lots and SKUs. A vial history is not a catalog of unopened lots. How to choose inventory software still owns the buying page. ELN versus LIMS still owns story versus sample state. This page only splits vial history from stock so those later pages are not asked to do both jobs at once.
A Vial History Is Not a Catalog of Unopened Lots
The search is sample tracking vs inventory software. Keep the objects. An aliquot history answers who held this tube, when it was split, and which experiment consumed it. A stock catalog answers how many unopened boxes of a SKU remain, which lot arrived last Tuesday, and whether the freezer map still matches the purchase order. Vendors sell both nouns in one brochure. The nouns are still different proofs. A scanner event on a box of tips is inventory. A scanner event on a labeled cryovial that has already been thawed twice is tracking. Collapsing them is how a lab buys a catalog and wonders why it cannot reconstruct a custody chain.
Prefer the job you can write in one sentence before you watch a demo. Reject a demo that shows a pretty freezer and calls it tracking because the vials are colored. Chain of custody as a legal definition is a later page. This page only names the software jobs.
History Versus Stock on the Same Rows
| Dimension | Sample-tracking software | Lab inventory software |
|---|---|---|
| Primary object | This aliquot, after it exists | This SKU or unopened lot |
| Typical event | Split, thaw, handoff, consume | Receive, store, decrement, reorder |
| What it can prove later | Who held the tube, and which run used it | That a lot was received and how many remain |
| What it cannot prove | That the unopened warehouse is accurate | That this thawed vial is the one in the methods |
| Common misfit | Using it as a shopping list for unopened boxes | Using it as a custody log for working aliquots |
A working freezer usually needs both sentences. That does not make them one SKU. A LIMS, when a lab has one, often carries sample state. That still is not this split: ELN versus LIMS is narrative versus aliquot state. Tracking versus inventory is history versus catalog. Three objects can sit in one building. They should not sit in one undifferentiated purchase.
What Each System Can Prove Later
When a result is challenged, tracking answers “which vial, which split, which person.” Inventory answers “which lot of reagent was on the shelf.” An ELN record answers “what this operator wrote about the run.” Sign-off readiness still owns whether that record may be signed. None of those pages is a reason to skip the other two objects. A catalog that decrements a box when someone types “used some” is not a vial history. A tracking log that cannot tell you how many unopened kits remain is not inventory.
Buying one tool for both jobs is allowed only after the gap is named. If the tool stores SKUs well and aliquots poorly, write that down. If it stores aliquots well and cannot reorder, write that down. Do not let a sales phrase — “full sample management” — erase the gap. ZettaFile is team file storage, not a LIMS and not an inventory product. Do not promote it as either.
Record Events After the Jobs Are Named
Name the job — aliquot history or stock catalog — before anyone opens a product. ZettaNote may record events after that sentence exists: that this run used this vial ID. It is an electronic lab notebook, not inventory software, and it is not a substitute for the Wave8 buying page. Official product language describes experiment documentation, templates, and access controls. Software does not complete 21 CFR Part 11 by storing a vial ID. If the only system in the lab is a spreadsheet titled “inventory” that also tries to be a custody log, you do not have either job finished. You have one sheet doing two proofs badly.
A challenged result almost always asks for the vial first and the catalog second. “Which aliquot went into that PCR” is a tracking sentence. “Did we still have that kit on the shelf last Tuesday” is an inventory sentence. Answering the second from a custody log, or the first from a reorder sheet, is how labs invent a history they cannot defend. Keep the two proofs on two objects even if one vendor later sells both. Write the object names on the purchase request. If the request only says “sample management,” send it back until the vial and the unopened lot are named.
Frequently Asked Questions
Is sample-tracking software the same as lab inventory software?
No. Tracking follows one aliquot. Inventory catalogs unopened lots and SKUs.
Is this the same split as ELN versus LIMS?
No. ELN versus LIMS splits story from sample state. This page splits vial history from stock catalogs.
