Description
Product Overview
The VitroView™ Hematoxylin and Eosin Stain Kit (model VB-3000s) is a premium assay kit engineered for histology and pathology laboratories that demand precise, reproducible staining results. Each kit contains two 30 ml dropper bottles—one filled with Mayer’s Hematoxylin solution and the other with a high‑purity Eosin solution—formulated to meet rigorous quality standards. The dropper bottles feature a calibrated dispensing tip that delivers accurate volumes, reducing waste and minimizing variability between slides. The kit dimensions are compact at 6 × 6 × 7 inches, making storage and handling straightforward, while the robust glass containers protect the reagents from light and contamination.
Manufactured by Vitrovivo Biotech LLC, a company known for its commitment to scientific excellence, the kit is certified for use in a wide range of tissue types, including formalin‑fixed, paraffin‑embedded (FFPE) specimens and frozen sections. The product’s ASIN (B0FMYYJDXF) and its ranking as #12 in the Assay Kits category underscore its acceptance among researchers seeking reliable staining solutions. The kit’s formulation is free from unnecessary additives, ensuring that the staining intensity is driven solely by the intrinsic properties of the dyes, which translates into clear, sharp contrast between nuclei and cytoplasmic components.
Usage
This stain kit is designed for routine histological workflows in academic, clinical, and commercial research settings. It is ideal for preparing slides for diagnostic pathology, teaching laboratories, and high‑throughput screening projects where consistency across large batches of samples is critical. The Hematoxylin component stains cell nuclei a deep blue‑purple, while the Eosin component provides a pink‑orange counter‑stain for cytoplasmic elements, extracellular matrix, and red blood cells. The dropper format allows technicians to apply the exact volume required for each slide, facilitating standardized protocols and reducing the risk of over‑ or under‑staining.
Typical usage involves deparaffinization, rehydration, and antigen retrieval steps followed by immersion in the Hematoxylin solution for a calibrated time (usually 3–5 minutes), rinsing, and then counter‑staining with Eosin for 1–2 minutes. The kit’s reagents are compatible with most common mounting media and cover‑slipping techniques, making it a versatile choice for a variety of downstream applications, including immunohistochemistry (IHC) where a clear baseline morphology is essential.
Because the solutions are supplied in dropper bottles, laboratories can integrate the kit into automated staining platforms with minimal adaptation. The kit also supports manual staining protocols, offering flexibility for labs that prefer hands‑on techniques. Whether you are processing a few diagnostic slides or thousands of research specimens, the VitroView™ kit delivers reliable, reproducible results that meet the stringent demands of modern histopathology.
Why Choose Us
VitroView™ distinguishes itself through a combination of rigorous quality control, transparent manufacturing processes, and a focus on end‑user experience. Each batch of Hematoxylin and Eosin is tested for optical density, pH stability, and contaminant levels, ensuring that the staining performance remains consistent across production runs. The reagents are formulated with a balanced ionic composition that minimizes background staining while enhancing nuclear detail, a critical factor for accurate morphological assessment.
Our commitment to customer support extends beyond the point of sale. Vitrovivo Biotech LLC provides detailed protocol sheets, troubleshooting guides, and direct technical assistance from experienced scientists. Should you encounter any issues with staining intensity, color balance, or reagent stability, our support team is available to help you optimize the protocol for your specific tissue type and equipment.
In addition, the kit is packaged in environmentally responsible materials, and the dropper bottles are designed for easy recycling where local regulations permit. This reflects our broader sustainability goals and aligns with the growing demand for greener laboratory practices.

FAQ
What types of tissue samples are compatible with this kit?
The kit works with formalin‑fixed, paraffin‑embedded (FFPE) sections, frozen sections, and fresh tissue specimens. It is suitable for both diagnostic pathology and research applications.
Can the dropper bottles be used with automated staining instruments?
Yes, the calibrated dropper tips are compatible with most automated slide stainers. The kit includes instructions for adapting the reagents to common instrument platforms.
How long can the solutions be stored after opening?
When stored at 2‑8 °C, protected from light, the Hematoxylin and Eosin solutions remain stable for up to 12 months. We recommend sealing the caps tightly after each use.
Is there a recommended protocol for adjusting staining intensity?
Staining intensity can be fine‑tuned by modifying incubation times or diluting the solutions with distilled water. Our technical support team can provide customized protocols based on your specific slide thickness and tissue type.
What should I do if I notice precipitates in the solution?
Occasional precipitates may form if the solution is exposed to temperature fluctuations. Gently warm the bottle in a water bath (no higher than 30 °C) and filter through a 0.45 µm membrane before use.
