Description
🔬 The 18mm x 180mm Filtration Solution: Borosilicate Glass 3.3
This specialized Test Tube with Arm is a vital component for any modern laboratory performing small-scale chemical separation, analysis, and collection. Designed to function as both a receiving vessel and a vacuum-compatible container, it significantly streamlines your vacuum filtration processes.
Unmatched Performance for Small-Scale Work
- Integrated Vacuum Arm: The permanently attached side arm test tube (or filtration tube) allows for direct connection to a vacuum source, facilitating rapid and efficient separation of solids from liquids in micro-scale setups.
- Precision Sizing: With exact dimensions of 18mm (outer diameter) × 180mm (length), this vessel is perfectly sized to fit standard laboratory racks and be used with small-scale funnels (e.g., Hirsch or micro-Büchner funnels).
Built with Borosilicate Glass 3.3 Excellence
Quality of chemistry glassware is paramount. This tube is constructed from premium Borosilicate glass 3.3, the industry standard for scientific applications.
| Feature | Benefit |
|---|---|
| Borosilicate Glass 3.3 | Extremely low coefficient of thermal expansion, making it highly resistant to thermal shock. |
| High Chemical Resistance | Inert to most acids and alkalis, ensuring sample purity and long-term use. |
| Durability | Higher mechanical strength and scratch resistance than common soda-lime glass. |
Ideal Applications
- Micro-scale Filtration: Quick and effective separation of precipitates.
- Small-batch Sample Collection: Secure container for filtrate or liquid samples.
- Vacuum Distillation: Can be adapted for use in simple low-pressure distillation setups.
