Description
The MEDILAB Storage Vial Internal Thread is a precision-engineered polypropylene vial designed for secure collection, preservation, and storage of liquid or solid laboratory samples. Its internal-thread design ensures a tight, controlled seal with the matching cap, reducing the risk of leakage during handling and transport. Built for accuracy, chemical resistance, and long-term dependability, this vial is essential for laboratories and industrial environments requiring contamination-free sample integrity.
Key Features
- Internal Thread Design: Threads located inside the vial provide an extremely tight and secure closure.
- Leak-Proof O-Ring Cap: Cap fitted with an O-ring enhances airtight sealing for high-integrity storage.
- High Clarity for Easy Visibility: The Transparent body allows quick sample inspection without opening the vial.
- Autoclavable: Withstands repeated sterilisation cycles without deformation.
- Chemically Resistant: Stable against various reagents, buffers, and biological materials.
- Freezer-Compatible: Suitable for low-temperature sample storage.
- Smooth Internal Surfaces: Ensures complete sample retrieval and minimises residue.
- Consistent Quality: Uniform moulding for reproducible performance across every batch.
