- High-Capacity Solvent Recovery: Our range includes large-format 1000 ml Lenz-Laborglas flasks, ideal for processing significant sample volumes in research and industrial laboratories.
LabFriend supplies rotary evaporator accessories from leading European glassware specialists:
- Lenz-Laborglas: Renowned for premium German-engineered laboratory glassware, providing a wide variety of socket and capacity options for professional evaporation.
- ISOLAB: Offers reliable and durable evaporating flasks designed for routine laboratory tasks and efficient solvent recovery.
A secure vacuum assembly is critical for safe evaporation; to further enhance your distillation or filtration workflow, we recommend exploring these related categories:
- Filtration Apparatus: Use LLG-filter holders to clarify your samples before the evaporation process begins.
- Syringe Filters: For small-scale sample preparation, utilize LLG Spheros or Sartorius Minisart units to protect your evaporator from particulates.
- NS Joints Accessories: Securely fasten your evaporating flasks using Lenz-Laborglas or ISOLAB joint clips and clamps.
- Stopcocks and Valves: Regulate vacuum levels or solvent flow using Lenz-Laborglas PTFE-plug stopcocks.
Unsure if a pear-shaped or standard round-bottom flask is more efficient for your specific concentration task? Our team provides local technical support to help you find the perfect glassware solution with fast shipping and competitive pricing.
Frequently Asked Questions
1. Why is the NS 29/32 joint size standard for evaporating flasks?
The NS 29/32 joint size is the industry standard for most laboratory rotary evaporators, ensuring that flasks from different manufacturers like Lenz and ISOLAB are interchangeable.
2. What is the benefit of a pear-shaped evaporating flask?
The tapered shape of a pear-shaped flask, such as those from Lenz-Laborglas, makes it much easier to recover small amounts of concentrated solid or liquid residue compared to a standard round-bottom flask.
3. Can I use these flasks with high-vacuum systems?
Yes, these flasks are made from high-grade borosilicate glass (like Boro 3.3) and are designed to withstand the vacuum pressures typical of rotary evaporation procedures.
4. How do I choose the right flask capacity?
You should generally choose a flask that is at least twice the volume of the liquid you intend to evaporate to prevent "bumping" or foam from entering the evaporator's vapor tube.
