Product details

An underwater molecular biology laboratory that can work automatically for a long time

A system for qualitative and quantitative monitoring of toxin producing algae (and algal toxins) in situ underwater

major function
esp_transparent.jpg

1. Long term, automatic, and continuous monitoring of changes in toxin producing algae and algal toxins

2. Long term, automatic, and continuous monitoring of changes in specific algae, bacteria, planktonic animals, etc

3. Provide customized molecular probe combination kits to meet customers' special needs

4. Monitoring results can be wirelessly transmitted to onshore base stations

5. It can work in situ underwater (withstand a water pressure of 50 meters), and can also work on monitoring platforms or in water station rooms

6. Samples can be collected and stored underwater, and analyzed in the laboratory after recycling






application area




1. Monitoring and early warning of harmful algal blooms esp.jpg

2. Monitoring of red tide algae, especially toxin producing algae and algal toxins

3. Monitoring of harmful algal blooms, blue-green algae, especially toxin producing algae and algal toxins

4. Environmental monitoring and ecological research on phytoplankton

5. Oceanography and Limnology Research

6. Safety monitoring of drinking water sources

7. Monitoring of Water Supply Safety in Water Plants







Measurement parameters




Main detection targets: harmful algal blooms related algae, algal toxins, marine bacteria, animal larvae, crustaceans.

ESP is a fully automated underwater molecular laboratory that currently uses three methods for molecular detection: sandwich hybridization (SHA), fluorescence quantitative PCR (qPCR), or competitive enzyme-linked immunosorbent assay (cELISA). But ESP is not limited to these two methods. Instrument manufacturers will constantly update and adopt new molecular methods suitable for ESP. Users can also develop and program new molecular methods for ESP application.

At present, the probes used for detection mainly target some toxic algae, bacteria, and planktonic animals, but the types that can be detected are not limited to the ones listed below. Not rightESPWith any modifications made to the hardware system, it is only necessary to design appropriate probes and reagent kits to detect new types.
