McKesson Capillary Tube Holding Tray - 24 Place Wax Sealant for Microhematocrit Tubes

Professional Laboratory Capillary Tube Organization and Sealing System

The McKesson Capillary Tube Holding Tray delivers efficient, reliable organization and sealing for microhematocrit capillary tubes in busy clinical laboratories, physician offices, and diagnostic testing facilities. This 24-place tray combines intelligent design with advanced wax sealant technology to streamline hematocrit testing workflows while ensuring accurate, contamination-free sample processing.

24 Numbered Places for Efficient Patient Identification

Designed with laboratory efficiency in mind, this holding tray features 24 individually numbered positions that enable quick, accurate patient sample identification and tracking. The numbered layout eliminates confusion in high-volume testing environments, reduces the risk of sample mix-ups, and supports proper chain-of-custody documentation. Laboratory technicians can easily organize multiple patient samples simultaneously, improving throughput and reducing turnaround times for critical hematocrit results.

Advanced Wax Sealant Technology

Each tray contains a unique, specially formulated wax compound that quickly forms a tight, secure seal around capillary tubes. This innovative sealant technology eliminates the need for plastic caps or time-consuming heat sealing procedures, dramatically reducing sample preparation time and simplifying laboratory workflows. The wax creates an immediate, reliable seal that prevents sample leakage, evaporation, and contamination during handling and processing.

Centrifugation-Resistant Performance

The proprietary wax sealant formulation is specifically engineered to withstand the high centrifugal forces encountered during microhematocrit testing procedures. Unlike inferior sealing methods that may fail under centrifugation stress, this advanced compound maintains its integrity throughout the entire testing process, ensuring accurate results and preventing sample loss. The sealant remains stable and secure even at maximum centrifuge speeds, providing consistent performance across diverse laboratory protocols.

Simplified Workflow Without Caps or Heat Sealing

Traditional capillary tube sealing methods require additional supplies and equipment, adding complexity and cost to laboratory operations. This innovative tray eliminates those requirements entirely—no plastic caps to inventory and manage, no heat sealing equipment to maintain and calibrate. Simply insert the capillary tube into the wax sealant, and the seal forms instantly. This streamlined approach reduces supply costs, minimizes equipment maintenance, and accelerates sample processing.

Latex-Free Construction for Patient and Staff Safety

Manufactured without natural rubber latex, this holding tray is safe for use in environments serving latex-sensitive patients and staff members. The latex-free construction eliminates allergy concerns and supports inclusive laboratory practices that prioritize the health and safety of all individuals.
