OEM customer identities and order volumes are kept strictly confidential. Formulas, processes, and order information are managed under tiered access control.
Technical & Regulatory Support
Registration led by you — technical docs and QC data by us.
The regulatory pathway is led by the client; we provide technical documentation, QC data, and batch-to-batch consistency records to support your compliance filings.
Why Choose Depthslide
Precision
Depth tolerance within ±1.5µm — verified batch by batch.
A study published in International Journal of Fertility & Sterility (2015) by Lu JC, Yue RQ, Feng RX, Kong LZ, Xu YC, et al. conducted actual depth measurements on six mainstream counting chambers (including Leja), finding that Leja (nominally 20µm) measured 20.49 ± 0.22 µm — confirming that depth precision is the core variable in CASA concentration calculations.
Surface Treatment
Nanoscale plasma treatment for more uniform sample loading and truer cell viability readings.
The chamber surface undergoes a nanoscale plasma treatment process, improving surface hydrophilicity, preventing bubble formation from uneven sample loading, and reducing the cell adhesion effect that causes viability decline.
Customization
Full specification customization — 15 days to first samples.
Depth (10–100µm+), chamber count (1–8), channel design, slide dimensions — all adjustable to your exact requirements.
Delivery
Annual capacity exceeding 1.5 million slides. 15-day lead time.
Standardized production line with 6 critical checkpoint quality controls per batch. Annual output exceeding 1.5 million slides, serving multiple countries worldwide. 15 days from design freeze to production completion. Global express shipping.
