About this item
Efficient Solvent Recovery with the Rotary Evaporator Flask
Continuous solvent evaporation and recovery are highly delicate procedures in organic chemistry. Using substandard glassware compromises the entire vacuum system, causing expensive solvents to escape into the atmosphere. A professional rotary evaporator flask quietly determines whether your distillation run succeeds or fails. Our premium pear-shaped receiving flask provides incredible vacuum integrity and thermal shock resistance, ensuring that your condensed liquids are collected safely and efficiently during rigorous laboratory workflows.
Maintaining structural reliability under extreme negative pressure requires strict adherence to international material standards. Professional research facilities explicitly follow the global ASTM E438 specifications for laboratory glassware to guarantee maximum chemical and physical endurance. We manufactured this rotary evaporator flask using highly pure Borosilicate 3.3 glass natively. It guarantees your analytical projects meet demanding scientific quality requirements flawlessly without dangerous implosions. Explore our complete Lab Glassware collection to secure the most reliable research consumables immediately.
1Premium Borosilicate 3.3 Construction
We engineered this receiving vessel to survive intense thermal cycling. Standard glass fractures instantly when chilled condensate drips down into a warm flask body. Fortunately, this product utilizes heavily thickened Borosilicate 3.3 glass natively. It boasts a remarkably low thermal expansion coefficient, easily handling a sudden temperature differential of up to 200°C safely. This extreme thermal shock resistance ensures the vessel survives daily autoclave sterilization runs and rigorous distillation heating baths without devitrifying.
2Precision Ground-Glass Taper Joints
Maintaining a flawless vacuum is the core principle of rotary evaporation. Loose connections drastically increase boiling times and waste valuable solvents. Thus, we equipped the neck of this rotary evaporator flask with meticulously precision-ground taper joints. Available in multiple industry-standard sizes (14#, 19#, 24#, 29#, and 24/40#), they mate flawlessly with compatible condenser assemblies. This creates an absolute airtight seal, maximizing your system’s vacuum hold time and efficiency.
3Optimized Pear-Shaped Geometry
Extracting the final drops of valuable synthesized oils from standard cylindrical flasks is incredibly frustrating. The specialized pear (or “eggplant”) profile of this receiving vessel solves this issue completely. The bulbous upper body maximizes the internal condensation collection area, while the gracefully sloped walls concentrate the recovered liquid down into the narrow base. This geometric optimization minimizes residual film loss and makes decanting into storage containers highly precise.
Core Capabilities of the Receiving Flask
🛡️ Chemical Inertness
Pure borosilicate glass ensures absolutely zero chemical reactions with aggressive boiling acids and harsh organic extraction solvents.
🔥 Heat Resistant
Handles extreme continuous operating temperatures safely up to 450°C (842°F) within dedicated laboratory heating oil baths.
⚖️ 38 Configurations
Available in 38 distinct combinations, allowing you to select the exact volume and joint size that matches your setup.
🔬 Scale Up Ready
Spans from micro-scale analytical 5mL volumes up to massive 5000mL (5 Liter) pilot-scale production batches seamlessly.
Investing in a reliable rotary evaporator flask is absolutely essential for maintaining strict solvent recovery efficiency. Our heavy-duty receiving vessels combine immense thermal shock resistance with perfect airtight ground joints, making them the ideal hardware solution for researchers purifying natural product extracts and organic synthetic compounds.

FAQs
Q1: Why use a pear-shaped flask instead of a standard round bottom flask?
A1: The unique pear (or “eggplant”) shape is specifically optimized for recovering solvents. Its bulbous upper body maximizes the condensation surface area, while the steeply sloped walls force the heavy liquid to pool neatly into the very narrow bottom tip. This makes it incredibly easy to pour and decant every last drop of your valuable solvent without leaving a sticky film on the walls.
Q2: How do I know which joint size to select?
A2: The joint size (e.g., 24#, 29#, or 24/40#) dictates the diameter and taper of the ground glass neck. You must check the specific condenser attachment or distillation adapter on your rotary evaporator machine. Your receiving flask’s joint number must perfectly match the machine’s attachment joint to create an airtight vacuum seal.
Q3: Can this flask withstand the heat of a boiling oil bath?
A3: Absolutely. Borosilicate 3.3 glass is legendary for its thermal stability. It can continuously and safely endure temperatures up to 450°C (842°F). It handles direct contact with laboratory heating mantles, silicone oil baths, and chilled condenser drips without shattering.
Q4: Should I apply grease to the ground glass joint before distillation?
A4: Yes. Applying a very light film of high-quality laboratory vacuum grease (like silicone stopcock grease) to the frosted joint prevents the flask from freezing or locking onto the condenser. It also acts as an extra sealant to ensure your vacuum pump achieves maximum negative pressure during the run.
