Field’s Stain ‘B’-Lancer

Field’s Stain ‘B’ – Lancer is an essential acidic counterstain designed for use in combination with Field’s Stain ‘A’ to rapidly and effectively stain blood smears for microscopic examination. Specially formulated by Lancer to meet the rigorous demands of field laboratories and clinical settings, Field’s Stain ‘B’ plays a vital role in hematology, especially for identifying and differentiating blood cells and parasites such as Plasmodium species in malaria diagnosis. As a component of the two-part Field’s stain system, this reagent provides critical contrast in cell structures, highlighting cytoplasmic elements in pink or red tones while Field’s Stain ‘A’ colors nuclei and parasites in blue or purple. The dual-stain method allows for high-resolution observation of thick and thin blood films, improving the efficiency and accuracy of laboratory diagnostics.

Field’s Stain ‘B’ by Lancer is based on eosin, an acidic dye known for its ability to bind to basic components of the cells, mainly cytoplasm and red blood cells. Its formulation has been carefully developed for optimal staining intensity and clarity, allowing healthcare professionals and lab technicians to clearly identify various hematologic structures under the microscope. This is particularly valuable in the detection of bloodborne parasites where rapid assessment and reliable visual cues are crucial. The product is frequently used in field stations, mobile clinics, remote diagnostic labs, and primary health care centers, where resources may be limited but high-quality staining is still essential.

One of the key advantages of Lancer’s Field’s Stain ‘B’ is its ready-to-use formulation. Unlike traditional stains that require extensive preparation, this product is pre-mixed and stabilized to ensure ease of application and consistent staining results. It significantly reduces processing time while delivering high-contrast images that aid in immediate diagnostic decisions. The solution is highly stable under standard storage conditions and retains its efficacy even in fluctuating environmental conditions. This makes it highly suitable for tropical and remote regions where medical personnel must work quickly and accurately without access to fully equipped labs.

Field’s Stain ‘B’ is particularly useful in resource-limited settings for the detection of malaria, as it enables rapid examination of thick blood smears, a method known for its sensitivity in identifying the presence of Plasmodium species. When used correctly, it enables not only parasite detection but also rough estimation of parasite density, helping clinicians determine the severity of infection. The stain provides distinct color differentiation, making it easier to distinguish between different blood components, such as lymphocytes, monocytes, neutrophils, and red blood cells, which is vital for thorough analysis.

In educational institutions, Field’s Stain ‘B’ – Lancer serves as a reliable tool for training students in parasitology, hematology, and microscopy. The consistent staining characteristics and clear visual differentiation help students and researchers identify and interpret various cellular structures effectively. Furthermore, the high-grade quality of this stain ensures minimal background staining and optimal contrast, which enhances learning and research accuracy. Whether in an academic setting or a high-throughput diagnostic lab, the stain maintains professional-grade performance and visual clarity.

Manufactured under stringent quality control procedures, each batch of Field’s Stain ‘B’ is thoroughly tested for dye concentration, pH stability, and microbial safety. Lancer adheres to industry standards for laboratory chemicals, providing all essential documentation including Certificates of Analysis (CoA) and Safety Data Sheets (SDS). This ensures the product meets both safety and performance expectations. Clear labeling and secure packaging further add to its usability and safe handling in clinical and educational environments. The packaging is designed to prevent leakage and degradation, with tamper-evident seals and clear usage instructions for hassle-free application.

Handling precautions include wearing protective gloves and eye protection during use to avoid staining or irritation. Though it is not classified as highly hazardous, proper laboratory practices should be followed to prevent accidental exposure. After use, staining solutions and waste materials should be disposed of according to local environmental and safety regulations. When stored properly in a cool, dark place, Field’s Stain ‘B’ retains its effectiveness for an extended period, making it a cost-effective and dependable choice for frequent use.

The Lancer brand is known for its commitment to quality, and Field’s Stain ‘B’ is no exception. It is a trusted product across healthcare facilities, academic institutions, research centers, and diagnostic laboratories globally. Customers choose Lancer for its reliable chemical performance, comprehensive documentation, and responsive customer service. The stain is competitively priced without compromising on quality, offering excellent value for laboratories that prioritize both cost-efficiency and accuracy in diagnostic staining.

In conclusion, Field’s Stain ‘B’ – Lancer is a superior acidic stain that complements Field’s Stain ‘A’ in the diagnostic staining of blood smears. Its effectiveness in enhancing cytoplasmic contrast makes it a valuable asset in identifying parasites, blood cell morphology, and hematological conditions. The product is crafted to meet the needs of both field-based and lab-based diagnostic work, combining ease of use, consistency, and professional-grade results. When you buy Field’s Stain ‘B’ from Lancer, you’re investing in a reagent that supports accurate, rapid, and reliable diagnostics – a critical element in both routine lab operations and emergency health responses.
