300mm Borosilicate Glass Westergren ESR Pipettes – Graduated ESR Tubes for Precision Blood Sedimentation Testing

Ensure clinical accuracy with our 300mm Borosilicate Glass Westergren ESR Pipettes. Specifically engineered for the “Macro Method” of Erythrocyte Sedimentation Rate (ESR) testing, these pipettes are crafted from premium-grade borosilicate glass to provide exceptional optical clarity and chemical resistance.

Each tube features a uniform internal bore, a critical factor in maintaining standardized sedimentation rates and preventing “wall effects” that can skew diagnostic results. With permanent, high-contrast white graduations ranging from 0 to 200mm, laboratory technicians can easily perform precise readings at the 1-hour mark. Designed to fit all standard 6-place or 10-place Westergren stands, these reusable pipettes offer a durable and cost-effective solution for hospitals and diagnostic centers.

Key Features

• High-Clarity Borosilicate Glass: Superior transparency for easy interface reading between plasma and red blood cells.

• Permanent Graduations: Clearly marked from 0 to 200mm in 1mm divisions; markings are acid-resistant and won’t fade during sterilization.

• Precision Bore Geometry: Uniform internal diameter (approx. $2.5\text{ mm}$) ensures consistent capillary action and reliable ESR values.

• Standardized 300mm Length: Fully compatible with standard push-type and spring-loaded Westergren stands.

• Eco-Friendly & Reusable: Can be easily cleaned and autoclaved for repeated use, reducing laboratory waste compared to plastic alternatives.
