Precision in diagnosis does not begin at the microscope.
It begins at the chemistry of staining.

Batch-to-Batch Reproducibility

Each tablet is pharma-grade and validated to maintain consistent performance over time, ensuring reliability for both traditional and digital pathology applications.

Optimized Quality & Diagnostic Standardization

Designed to support precision under the microscope, ensuring standardized staining quality and reliable diagnostic interpretation.

Digital & Computational Pathology Ready

Engineered to meet the demands of modern pathology, supporting enhanced image analysis and reducing variability in AI-assisted diagnostic workflows.

Consistency is not achieved. It is designed.

A New Generation of Stains

Designed with
pharmaceutical precision.

Solid-tablet formulations that combine active staining agents with stabilizing components in a controlled, reproducible format — minimizing variability, maximizing performance.

Four pillars · Zero compromise

Engineered around what matters.

Stable & Long-Lasting

Chemical stability ensures extended shelf life without degradation from light or temperature — a major limitation of liquid solutions.

Space-Saving Format

The tablet form replaces bulky liquid containers, reducing storage volume by up to 90% and simplifying logistics.

StainTabs vials

Sustainability

Less packaging, easier disposal. A sustainable alternative that reduces plastic waste and supports safer, fully recyclable disposal.

Zero Flammability

No liquid, no hazard. The solid format enables safer handling, removes ADR transport concerns and simplifies shipping.

Precision staining has never
been this effortless.

Just drop it in distilled water. Done.

Insights from the VEED Project

Standardizing H&E staining to improve histopathological consistency.

The VEED Project evaluated a new tab-based H&E stain developed to reduce solution decay and improve reproducibility. Thirteen expert pathologists blindly compared 24 pairs of histological images.

The Result

The novel stain proved non-inferior to the standard approach overall (z = 2.7) and demonstrated significantly better visualization of stromal tissue (p = 0.008).
