The MEDILAB Test Tube with Interchangeable Stopper and Graduations is a precision-engineered laboratory tube designed for accurate measurement, secure sample storage, and reliable experimental handling. The integrated graduations allow quick volume estimation, while the standard interchangeable stopper ensures leak-proof sealing for transport, incubation, or chemical storage. Its robust construction makes it ideal for routine and analytical applications across research labs, universities, pharma, biotech, and QC/QA laboratories.

Key Features

• Interchangeable Ground-Glass Stopper for tight, contamination-free sealing.
• Graduated Scale for easy visual volume reading and improved workflow efficiency.
• Precision-Built Borosilicate Glass 3.3 offering exceptional thermal and chemical resistance.
• Smooth, Rounded Rim for safe handling and reduced chipping risk.
• Heat, flame, & Chemical Resistant ideal for heating, mixing, and storage tasks.
• Uniform Wall Thickness ensures mechanical strength and consistent performance.
• Autoclavable without deformation or staining.
• Reusable Laboratory-Grade Construction reduces long-term operating costs.

 

 Material Specifications

• Material: Borosilicate Glass 3.3

Properties:

• High thermal resistance (low coefficient of expansion 3.3 × 10⁻⁶ /°C)
• Excellent chemical durability against acids, alkalis, and solvents
• High mechanical strength and scratch resistance

• Standards: Manufactured according to relevant ISO and DIN laboratory glassware standards for dimensional accuracy and durability.

Technical Specifications

Available Capacities:

• Standard capacities commonly include 5 ml to 50 ml (as per the standard size table)

Dimensions:

• Varies by capacity—typically includes consistent outer diameter, length, and graduation spacing for laboratory compatibility.

Graduation Accuracy:

• Clear, permanent, easy-to-read graduations with controlled tolerance as per international standards.

Stopper:

• Interchangeable ground-glass stopper (standard taper).

Calibration:

• Non-calibrated; graduation marks for approximate measurements.

Packaging:

• Individually or bulk-packed in durable, export-safe boxes with protective separators.

Accessories Included:

• A matching interchangeable stopper is supplied with each tube.

Handling & Precautions

• Safe Use: Avoid sudden temperature changes to prevent thermal shock.

• Cleaning: Wash with mild detergents; fully rinse to remove residues.

• Autoclaving: Autoclavable at standard temperatures (121–134°C). Always loosen the stopper before autoclaving.

• Heating Limits: Suitable for direct flame exposure, water baths, and dry heating within glass limits.

Do’s:

• Inspect for cracks before use
• Store upright to protect the stopper and rim

Don’ts:

• Do not expose to strong mechanical impacts
• Do not tighten the stopper during heating or sterilisation

Best Practices:

• Replace worn or chipped stoppers
• Use proper tube holders and clamps when heating
