Portable Automatic Water Sampler

The field
sampler,
reimagined.

SYP collects up to 58 timestamped, sealed water samples over deployments of up to 12 months — unattended, in caves, springs and remote catchments.

Fewer site visits. More complete time series.

The problem we set out to solve

You miss
the events that matter.

Remote access

The site is hours away

Cave dripwaters, mountain springs, remote catchments — many of the most scientifically interesting sites are the hardest to reach. Manual sampling regimes quickly become logistically impossible, or simply too dangerous.

Data continuity

Events don’t keep a schedule

Storm events, seasonal transitions, episodic flow pulses — the moments that answer your research questions rarely happen on a convenient schedule. If you're not there, you lose the sample.

No off-the-shelf solution

Nothing was built for this

Existing autosamplers were designed for wastewater treatment plants and industrial monitoring — heavy, mains-powered, and ill-suited to the realities of field science. SYP was designed from scratch for researchers who go to hard places.

Where SYP has been.

Reconstructing Classic Maya droughts

David Hodell, Ola Kwiecen, Daniel James and co-authors deployed SYP in Grutas Tzabnah to collect weekly 15 ml drip-water samples over a full year — providing data for a speleothem reconstruction of drought events during the Classic Maya period, published in Science Advances.

150 m underground, beneath a sequoia forest

Dr Yuval Burstyn deployed SYP in Crystal Cave — 150 metres beneath a giant sequoia forest in the Sierra Nevadas — where it autonomously collected 31 samples from atmospheric river events over six months. Data presented at the Climate Change and the Karst Record conference, Cape Town 2025.

SYP MkIII enters the Yucatán

Oana Dumitru (University of Florida) and Fernanda Lases-Hernández (UNAM) installed a MkIII SYP — complete with rain jacket — among the stalactites of a Yucatán cave, gathering autonomous samples through the season.

Sampling without disturbing the bats

UC Davis PhD student Kesego Letshele installed SYP in Oregon Caves National Monument to quietly collect drip water through winter — without disturbing the hibernating bat population. Exactly the kind of long-term autonomous deployment that manual sampling makes impractical.

"Drip water was collected using a SYP (Waikato Scientific Instruments, waikatoscientific.com) autosampler, beneath an active drip... The SYP collected the first 15 ml of drip water to accumulate in each 7-day interval in 15-ml sealed polypropylene sampling vials."

Named in Science Advances

SYP is cited by name — with URL — in the methods section of a peer-reviewed paper in Science Advances. The instrument's data contributed to a major reconstruction of Classic Maya drought response.

Firmware UI + Data Portal

See the software
before you deploy.

Every SYP ships with two interfaces: a firmware UI served from the sampler itself for field configuration and control, and the SYP Portal — a cloud platform for everything that happens after. Both run in your browser, and both have live demos you can explore right now.

Firmware UI live status screen: vial 4 in progress, sensor readings and battery health Firmware UI sensor log chart with Stop, Skip and Reset controls Firmware UI deployment settings: sampling mode, site name, sample count and period Firmware UI downloads screen for retrieving sample data and logs Firmware UI menu with settings, downloads, diagnostics and system controls

Gravity
Pump

Gravity mode

Designed for collecting water drips from a height — cave dripwaters, rain gauges, spring seeps. Water flows into the machine by gravity alone; no pump means no mechanical contamination risk and simpler maintenance.

Supports timed, delayed-start, and continuous flow-proportional sampling. Full vial detection ensures consistent sample volume and logs fill time so you can infer flow rate from timestamps.

Cave hydrology Flow-proportional Speleothem research Rain gauges Spring seeps

Pump mode

A peristaltic pump draws water from a reservoir or surface water body into vials at user-defined intervals. Ideal for sites where gravity flow is insufficient — cramped setups, low hydraulic head, or active groundwater monitoring.

The pump runs for a pre-determined duration per sample, with full vial detection to validate volume. Supports timed and delayed start modes.

Groundwater monitoring Surface water Stormwater Wetlands

External trigger mode

SYP responds passively to a 12V pulse from an external datalogger or controller — well suited to flow-proportional sampling setups where sampling decisions are made by a third-party sensor network. SYP simply executes the sample on command.

Logger integration Flow-proportional Event sampling
Signature feature

Full vial detection

SYP senses the moment each vial reaches its 15 ml volume and timestamps it. Because higher flow fills a vial faster, the fill record doubles as a flow record, which makes passive, flow-proportional sampling in sealed vials possible with no flow meter and no external power.
