Seachem Copper Test Kit, 75+ Tests for Marine and Freshwater

Seachem MultiTest: Copper is a copper test kit for marine and freshwater testing, with a 0–0.80 mg/L range and detection to less than 0.01 mg/L.

• More than 75 tests per kit — test copper repeatedly with one kit.
• Multi-cavity plate — run up to 6 tests at the same time.
• Reference sample included — validate the test.
• Measures all types of copper — use the kit across marine or freshwater testing.
• Precision of 0.025 mg/L and 0.0025 mg/L — two precision figures are provided for interpreting the test’s measurement performance.

When you need to measure copper in a marine or freshwater sample, this kit provides a defined range and a highly sensitive, catalysis-based procedure. Its multiple-test capacity also suits situations where you want to run several tests together, while the included reference sample gives you a way to validate the test.

What does Seachem MultiTest: Copper measure?

It measures all types of copper, with detection to less than 0.01 mg/L across a range of 0–0.80 mg/L. The procedure is based on catalysis and is designed for high sensitivity, making the kit suitable for measuring copper in either marine or freshwater.

• Measurement range: 0–0.80 mg/L.
• Detection: less than 0.01 mg/L.

How many tests are included, and can I validate them?

One kit performs more than 75 tests and includes a reference sample for test validation. The reference gives you a sample to use when checking the test, and the stated precision figures are 0.025 mg/L and 0.0025 mg/L.

• Reference sample included for validation.
• Precision figures: 0.025 mg/L and 0.0025 mg/L.

Can I run multiple copper tests at once?

Yes. The multi-cavity plate lets you run up to 6 tests at the same time. This format is useful when you have several samples to test in one session, rather than running each test separately.

• Simultaneous testing capacity: up to 6 tests.

Is this kit for marine or freshwater testing?

Seachem MultiTest: Copper is made for both marine and freshwater testing. Its stated scope covers all types of copper, so it is suited to buyers who want one copper test kit for either water type.

• For marine water testing.
• For freshwater testing.

This kit is a good fit for aquarium keepers who need to measure copper in marine or freshwater samples, want a catalysis-based test, or prefer to process several tests together. Its over-75-test capacity, validation reference, and multi-cavity plate combine repeated testing with a defined copper measurement range.
