Four models, one instrument
One instrument across the whole crop cycle
Most quality tools answer one question at one moment. This one follows the plant, from the first leaf sample to the finished extract: the same instrument, the same account, one continuous record.
Nutrient status from leaf tissue
Plant Tissue model
Potency and terpene profile
Cannabis Analysis and Express models
Moisture and water activity
Cannabis Analysis model
Potency on solid extracts and hash
Solids Extracts model
Manifesto
Every decision
in the grow room,
backed by
a number.
Eight nutrients in one scan
Results come back in the same units used by laboratory leaf analysis.
How to take the sample
Drying and curing
Cure on a number, not on feel
Moisture and water activity are the two numbers that decide when a lot is ready and how long it will keep. Measure them in the drying room as often as the process needs, and release every lot on data.
How it works
From sample to result
Ground material in the powder dish, sample weight on top: a constant optical path, every time.
Prepare
Dry and grind flower or leaf. Solid extracts go straight into the dish.
Calibrate
Eight seconds on the white reference tile at the start of each session.
Scan
Results appear in the app in seconds.
Act
Adjust the feed, time the harvest or release a lot, with data behind every decision.
No solvents·No consumables·No sample sent anywhere
Data and platform
Every room, every site, one record
Every measurement syncs to the cloud portal. Trend charts, average, standard deviation and CV per parameter, material and lot make drift visible before it becomes a rejection.
The partnership
Swiss instrument. Cannabis-only science.
BÜCHI Labortechnik AG
Manufactures the analyzer and runs the platform behind it: mobile apps, cloud portal, firmware and security framework.
Valenveras
Owns, develops and maintains the cannabis models, and handles subscriptions, sample-preparation guidance and technical support. A team that works on cannabis and nothing else.
Where it fits
Where it fits next to your accredited lab
VALENVERAS PORTABLE LAB
Routine monitoring, in house
Fast, reagent-free results from cannabis-specific models, as often as the process needs.
ACCREDITED LABORATORY · HPLC / GC
Confirmation and compliance
Reference methods for regulatory testing and anywhere an accredited result is legally required.
Which materials can it analyze?
Dry flower, fresh flower, fresh leaves and solid extracts or hash. Fresh material is dried before scanning, and everything is measured in the powder dish with its weight, following the sample preparation SOP.
How do I sample leaves for nutrient analysis?
From week six, take the newest fully formed leaves from the third internode, with the petiole, from at least five plants per genetic. Dry, grind finely and scan like flower.
How accurate is it compared with a laboratory?
In six studies against five ISO 17025-certified laboratories, 21 of 25 THC comparisons fell within one percentage point of the lab result.
We run several sites. Will the instruments agree?
Yes. Three separate units tested on the same samples returned comparable results, without recalibrating each unit.
Does it need an internet connection?
Only for the first sign-in. Models are then cached on the instrument, a full session runs offline, and up to 999 spectra are stored and synchronized later.
Is it difficult to use?
It is designed for one-handed operation and requires minimal training. The app guides every step, from calibration to result.
Does it replace my accredited lab?
No. It handles routine, in-house monitoring. Accredited laboratories remain the reference for confirmation and regulatory testing.
