Efficient liquid-liquid extraction relies on high-quality glassware that ensures precise phase separation and chemical durability. LabFriend provides a specialized range of components for extraction, located within the distillation and synthesis section of our distillation, separation, and filtration department. These professional tools are essential for isolating compounds based on their relative solubilities in immiscible solvents.
Why Choose Professional Extraction Components?
Our curated collection of extraction hardware is designed for ergonomic handling and leak-proof operation:
- Precision Separating Funnels: We stock Lenz-Laborglas Conical Separating Funnels in sizes ranging from 100 mL to 2000 mL, manufactured from high-grade borosilicate glass to withstand aggressive organic solvents.
- Standardized Ground Joints: Most Lenz-Laborglas models feature NS 19/26 or NS 29/32 ground glass joints, ensuring a secure and vacuum-tight fit with standard laboratory glassware.
- Durable Funnel Support: Utilize the ISOLAB Separatory Funnel Holder or the Kartell Separating Funnel Holder, both crafted from chemical-resistant polypropylene (PP).
- Chemical-Resistant Stopcocks: Our funnels are equipped with high-precision PTFE or glass stopcocks for fine-tuned control during the drainage of the lower phase.
LabFriend supplies extraction components from the manufacturers featured in our high-performance range:
- Lenz-Laborglas: Renowned specialists in laboratory glassware, providing a wide variety of conical and cylindrical separating funnels for professional use.
- ISOLAB: Providers of high-quality laboratory consumables and supports, including ergonomic PP funnel holders for secure benchtop setups.
- Kartell: Leaders in plastic labware, offering durable and chemical-resistant supports for various extraction glassware sizes.
- LLG Labware: Offers a cost-effective range of reliable extraction accessories and laboratory essentials for routine separation tasks.
- Thermo Scientific: A global leader in science, providing high-performance components designed for complex extraction and synthesis workflows.
Successful extraction often serves as a precursor to more advanced analytical techniques; to further enhance your workflow, we recommend exploring these related categories:
- Solid Phase Extraction (SPE): Use Macherey-Nagel or Biocomma SPE columns for rapid sample cleanup when traditional liquid-liquid extraction is not required.
- Solvent Storage & Handling: Securely manage and dispense the immiscible solvents required for your extraction using DWK Duran or SCAT systems.
- Vials & Septa: Collect your isolated extracts in LLG Labware or DWK Kimble vials for subsequent chromatographic analysis.
- Laboratory Timers: Monitor the required settling time for phase equilibrium during complex extraction procedures.
Unsure if a 500 mL or 2000 mL separating funnel is best for your current solvent volumes? Our team provides local technical support to help you find the perfect extraction solution with fast shipping and competitive pricing.
Frequently Asked Questions
1. Why is borosilicate glass preferred for separating funnels?
Borosilicate glass, used in Lenz-Laborglas funnels, offers superior thermal resistance and high chemical durability, which is essential when handling volatile or corrosive solvents.
2. What is the benefit of a polypropylene (PP) funnel holder?
PP funnel holders from brands like ISOLAB and Kartell are highly resistant to chemical spills and are designed to securely grip the funnel without the risk of scratching the glass.
3. What do the NS numbers (e.g., NS 29/32) signify?
NS stands for "Normal-Schliff" (standard ground joint). The numbers represent the diameter and length of the joint in millimeters, ensuring compatibility with other standardized glass components.
4. Can the Kartell funnel holder support different funnel sizes?
Yes, the Kartell separating funnel holder is adjustable and designed to accommodate various funnel dimensions up to a 1000 mL capacity.
