About this item
Professional Filtration with the Long Stem Glass Funnel
Equip your analytical laboratory with our professional-grade long stem glass funnel. We designed this specialized glassware to facilitate the safe and rapid transfer of liquid reagents during complex chemical filtration processes. It protects researchers from hazardous chemical splashes by reaching deeper into receiving flasks. Whether you are conducting academic chemical analysis or industrial solvent separation, this long stem glass funnel delivers reliable, contamination-free fluid management.
Furthermore, handling aggressive chemical reagents requires strict regulatory compliance. Professional laboratory directors explicitly follow the OSHA 1910.1450 standard for occupational exposure to hazardous chemicals to ensure secure working environments. By utilizing our highly inert borosilicate glassware, you maintain pristine sample purity while guaranteeing occupational safety. Explore our full range of Lab Glassware to ensure comprehensive analytical capabilities for your daily operations.
1Premium Boro 3.3 Glass Construction
We engineered the long stem glass funnel for diverse and demanding thermal applications. Standard thin glassware shatters instantly when exposed to boiling solvents. Fortunately, our filter funnel utilizes thickened Borosilicate 3.3 glass natively. It features an incredibly low coefficient of thermal expansion, ensuring it withstands severe thermal shocks and highly corrosive acids securely.
2Optimized Long Stem for Capillary Action
Slow filtration rates cause frustrating delays in analytical workflows. Thus, we equipped this glassware with an extended, narrow stem. This specific design allows the tip to touch the inner wall of the receiving beaker, creating a continuous liquid column. This capillary action physically pulls the filtrate through the filter paper much faster, significantly accelerating your workflow.
3Reinforced Thickness and Polished Rims
Flimsy funnel rims chip easily, posing severe laceration risks to laboratory technicians. Consequently, every Xin Tester analytical funnel features a reinforced, thickened wall design alongside meticulously fire-polished edges. It provides exceptional impact resistance and ensures burr-free handling, maximizing physical safety in high-intensity educational or industrial lab environments.
Core Capabilities of the Filter Funnel
📐 Standard 60° Cone
Designed with a precise 60-degree inner cone to securely hold folded filter paper, ensuring maximum surface contact and zero bypass.
🔍 High Transparency
Provides superior light transmission, allowing researchers to continuously monitor liquid clarity and detect unexpected precipitates instantly.
♨️ Fully Autoclavable
Highly resistant to thermal degradation, meaning it can be safely sterilized in autoclaves for strict biological and clinical applications.
⚖️ Multiple Capacities
Available in precise mouth diameters ranging from 30mm for micro-sampling up to 120mm for large-volume industrial separations.
Investing in a reliable long stem glass funnel is absolutely essential for maintaining strict scientific accuracy. Our filtration tools combine immense thermal shock resistance with laboratory-grade inertness, making them the perfect solution for researchers evaluating complex chemical separations.
FAQs
Why should I choose a "Long Neck" funnel over a short neck version?
The long neck on the Xin Tester triangle funnel is designed to provide better stability when placed in tall-necked flasks. It also helps create a continuous liquid column which facilitates a faster filtration rate due to the increased gravitational pull on the filtrate.
Is the Boro 3.3 glass safe for use with boiling liquids?
Absolutely. High borosilicate 3.3 glass has excellent thermal resistance. It can withstand high temperatures and rapid temperature changes that would cause ordinary glass to shatter, making it ideal for filtering hot chemical solutions.
Why are the smaller sizes (30mm-50mm) sold in 4-piece packs?
Smaller funnels are frequently used in micro-scale experiments or multiple parallel setups. Selling them in a 4-piece pack ensures you have enough units for complex projects and provides better value for laboratory restocking.
Can these funnels be cleaned in a lab dishwasher or autoclave?
Yes, these funnels are compatible with standard laboratory cleaning procedures. They are resistant to chemical detergents and can be autoclaved for sterilization, as long as the temperature ramp is controlled to prevent excessive thermal stress.
