Storage Vial- Internal Thread

The GISCOM 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.

Handling & Precautions

• Sterilise in an autoclave at 121°C; avoid overheating to prevent deformation.
• Ensure the O-ring is properly seated before sealing to maintain leak-proof performance.
• Avoid using harsh abrasives or industrial cleaners; wash with mild detergents.
• Store away from direct sunlight and extreme temperatures to maintain polymer stability.
• Do not use for long-term storage of highly volatile or aggressive organic solvents.
• Inspect vials regularly when used for cold storage or repeated sterilisation.

 Applications

• Biotechnology & Research: Enzyme storage, reagent aliquots, micro-sample handling
• Clinical & Diagnostic Labs: Secure sample collection and transport
• Pharmaceutical QC/QA: Stability testing, controlled storage of small-volume analytical samples
• Chemical Laboratories: Storage of chemical test samples, standards, and buffers
• Academic & Government Research: Daily sample preparation, archiving, and teaching labs

The secure internal-thread sealing system makes this vial ideal for workflows requiring maximum sample security, contamination prevention, and reliable long-term preservation.
