The continuous flow centrifuge is used at our field sites to sample suspended sediments, which we then analyze for microplastics and/or phosphorus and other nutrient species.

The centrifuge collects samples in specialized centrifuge bowls. It requires the use of an additional peristaltic pump, and we have also equipped the pump and centrifuge setup with a flow meter to monitor the total volume pumped to the centrifuge and the flow rate.

 

Peristaltic Pump (Spectra Field Pro)

pump equipment in blue metal case

We use the Spectra Field Pro Peristaltic Pump for groundwater and surface water sampling. It pumps up to 2.5 litres per minute and as low as 40mL per minute.

LCD display provides real-time flow rates, allowing the user to quickly make changes as needed. 

Universal Percussion Corer and Core Extruding Apparatus (Aquatic Research Instruments)

3 configurations of core tube barrel connected to different attachments for collecting corecore tube connected to extruding apparatus including threaded rod at bottom and extruding funnel at top

Collects sediment cores up to ~ 100 cm long from environments such as marshes, ponds, reservoirs, and lakes with relatively shallow water.

Core extruding apparatus facilitates incremental extrusion and sectioning of cores into 1 cm sections.

 
 

Handheld multi-parameter (pH, ORP, DO, temperature and conductivity) meter (YSI) x2

YSI

The YSI Professional Plus handheld multi-parameter meter provides flexibility for the measurement of dissolved oxygen, conductivity, pH, ORP, and temperature.

Our YSI includes a flow cell, which is ideal for use in applications when it is impossible to submerge the probe module into the sample, such as for sampling groundwater.

 
Peepers
 
Peepers

Peepers are passive (diffusion) pore water sampling devices that are used to determine vertical pore water profiles in soils and sediments at a cm-scale resolution. The peepers can be used to collect anoxic pore waters without degassing and/or oxidizing artifacts.

Water level and temperature loggers (Troll-500, In Situ Inc.) (x2)

metal casing of level logger connected to level logger

This data logger can be used for measuring and logging water levels and temperatures in wells, streams, lakes and freshwater wetlands.

We are currently using these level loggers to monitor water levels and estimate discharge at the inlet and outlet of our Urban Observatory stormwater pond monitoring site.

 

Water Level Data Logger (HOBO) (x5)

hobo

The HOBO Water Level data logger is a high accuracy, pressure-based water level data logger (0-4m range, +/- 3mm). This data logger can be used for measuring and logging water levels and temperatures in wells, streams, lakes and freshwater wetlands. Our kit includes a HOBO waterproof shuttle with coupler and BHW-PC HOBOware Pro Software.

Drive-point ​Piezometer Groundwater Sampling Kit

piezometer

We use the AMS "Piezometer Groundwater Sampling Kit" for shallow groundwater sampling investigations. This complete kit includes everything needed to take groundwater measurements and collect samples to a depth of 12 feet below the surface. This kit includes an AMS Big Foot removal jack and T-Jack Adapter for removal of the extensions and piezometer. 

 


Soil Temperature Profile Probe

probe

We use this "Soil Temperature Profile Probe" to measure the temperature profile at fixed depths in soils. Inside a tube made of glass-fibre reinforced plastic, 6 temperature sensor elements are placed at different depths. The probe has analogue output signals 0 to 1V corresponding to -20 to +50°C. The probe is connected directly to the plus of a 6-channel logger with an eight meter extension cable.
