• Microcolumn Gel Card Series: Includes Anti-human Globulin Test Cards, ABO and RhD typing cards, and reagents for rapid antibody release. Used for alloantibody detection, compatibility testing, and blood group determination. Shelf life: 1–2 years.

2. Fecal Occult Blood Testing

• Reagents for chemical and immunological detection of fecal occult blood, including test strips, tubes, slides, and controls. Moderate sensitivity with stable color development lasting 30 minutes. Shelf life: 6 months to 2 years.

3. Staining Series for Cytology, Hematology, and Microbiology

• Wright-Giemsa, Liu's, Reticulocyte, Diff-Quik, Gynecology Leucorrhea, Gram, and Tuberculosis Stain Series: Provide rapid, sensitive, and clear staining for blood cells, marrow, vaginal secretions, bacteria, and acid-fast organisms. Most comply with WHO standards. Shelf life: generally 2 years.
• Consistently High Clarity Stain Series: High-definition staining kits for 1 to 2000 smears, including hematoxylin and eosin variants. Shelf life: 1.5 years.
• Papanicolaou and Hematoxylin & Eosin (H-E) Stain Series: Widely used for cervical cancer screening and tissue staining with clear nuclear and cytoplasmic visualization. Shelf life: 1.5 years.
• Histology Stain Series: Specialized stains for tissue components such as amyloid, collagen, mucopolysaccharides, fats, elastic fibers, and Helicobacter pylori. Shelf life: 1 to 1.5 years.

4. Cytochemistry and Reproductive Medicine Stains

• Cytochemistry Stain Series: Enzyme activity and leukocyte characterization stains including ANAE, PAS, iron, and phosphatase stains. Shelf life: ~1 year.
• Reproductive Medicine Stain Series: WHO-recommended stains for sperm morphology, vitality, and fertility assessment, including Diff-Quik, Papanicolaou, Eosin-Nigrosin, and Acridine Orange. Shelf life: 1.5 to 2 years.

5. Microbial and Fungal Stains

• Fluorescence stains for fungi, bacterial structural stains (spore, flagella, capsule), and urine sediment stains. Used for detailed microbial identification and viability assessment. Shelf life: 1.5 to 2 years.

6. Preservation and Miscellaneous Reagents

• Bacillus Preservation Tubes: For normal bacteria preservation, including oxygen-sensitive strains, with bead options. Shelf life: 2 years.
• Dewaxing agents as safer alternatives to xylene for tissue processing. Shelf life: 2 years.
• Mounting resins for preserving stained tissues and smears. Shelf life: up to 4 years.

7. Cleaners and Reagents for Automated Analyzers

• Includes antibacterial, alkaline, acid, deproteinized cleaners, thermostatic additives, and probe cleaners compatible with major analyzer brands (HITACHI, OLYMPUS, TOSHIBA, ABBOTT, BECKMAN COULTER, SYSMEX). Packaging from 500ml to 20L. Shelf life: 1–2 years.
• Hematology analyzer reagents such as lyse solutions, diluents, stabilizers, sheath liquids, and flushing liquors compatible with multiple analyzer models. Shelf life: 1–2 years.

8. Medical Devices

• Laboratory equipment including centrifuges (capillary and large capacity), plasma thawing/freezing systems with intelligent temperature control, autostainers, card centrifuges, and incubators designed for various sample processing needs.

Critical Information and Best Practices

• Strict adherence to specified shelf lives (6 months to 4 years) is essential to maintain reagent efficacy.
• Use dewaxing agents to reduce exposure to hazardous solvents like xylene.
• Follow WHO-recommended staining protocols, especially in reproductive medicine, to ensure accurate diagnostics.
• Employ brand-specific cleaners and maintenance reagents to optimize analyzer performance and longevity.
• Utilize fluorescence and specialized microbial stains for precise identification of fungi and bacteria.
• Proper storage and handling are implied to preserve reagent stability and performance.
