01How do I submit samples to Silt Lab Zone?
You can drop samples off directly at our Nishi-ku facility during business hours (Monday to Friday, 8:30 to 17:30). We can also arrange courier collection for larger submissions or for clients outside Nagoya. Sample containers and submission forms are available on request by email or phone. Please do not submit samples without a completed submission form, as this delays processing.
02What is the minimum sample quantity required for grain-size analysis?
For combined sieve and laser diffraction analysis, we require a minimum of 200 grams of dry sediment or 500 grams of wet sediment. For fine-grained samples (predominantly silt and clay), 100 grams dry weight is sufficient for the laser diffraction stage alone. If you are unsure whether your sample volume is adequate, contact us before dispatching.
03Can you issue results in English for international project reporting?
Yes. We can issue reports in English on request at no additional charge. The data tables, parameter names, and regulatory threshold comparisons are all translated. Please specify English reporting on your submission form. Note that regulatory references will still cite Japanese standards (JIS, Ministry of the Environment notifications), as these are the applicable standards for work conducted in Japan.
