Product Overview
The Small Vacuum Rotary Evaporator is a compact benchtop system designed for solvent distillation, concentration, and purification in small-volume laboratory applications(0.25L−2L).
By reducing the internal pressure via a vacuum source, the boiling point of the target solvent drops significantly. This allows evaporation to occur at much lower temperatures, preventing thermal degradation of heat-sensitive compounds. Its compact footprint makes it highly adaptable for standard laboratory fume hoods in pharmaceutical R&D, chemical analysis, and botanical/hemp extraction facilities.
For equipment distributors and scientific suppliers, this benchtop solvent recovery system offers a highly stable, low-maintenance product with reduced shipping volume and global electrical compatibility.
Key Technical Features & Commercial Advantages
Compact Footprint & Low Logistics Cost
• The Reality: Standard industrial rotary evaporators require dedicated floor space or reinforced benches. This model is engineered with an integrated, vertical layout to minimize bench space.
• Buyer Benefit: Fits easily into existing standard laboratory fume hoods without requiring expensive lab modifications.
• Distributor Advantage: Reduced package dimensions lower individual air and ocean freight costs, directly improving your landed margin.

Controlled Film Evaporation
• The Mechanism: A motorized drive spins the evaporating flask at20−200 rpm.Centrifugal force pushes the liquid against the glass walls, creating a continuous, ultra-thin film.
• User Benefit: This film dramatically increases the active surface area for heat transfer, speeding up distillation and preventing sudden fluid boiling ("bumping").
Borosilicate Glass 3.3 & Vacuum Tightness
• Material Precision: All glass components are fabricated from Borosilicate Glass 3.3, providing premium resistance to thermal shock and corrosive organic solvents (such as acetone, hexane, and chlorinated hydrocarbons).
• Sealing System: Employs a composite PTFE + FKM double sealing ring capable of maintaining steady vacuum levels during extended, continuous operation cycles.
Stable Heating Bath
• Performance: The heating bath supports both water and oil media, delivering temperatures from ambient up to 180 ∘ C with a control accuracy of ±1 ∘ C.
• User Benefit: Eliminates temperature spikes, ensuring high repeatability for analytical sample preparation.

Target Markets & Applications
Pharmaceutical & Biotech Hubs: Small-batch active ingredient (API) concentration and solvent exchange.
Chemical Testing Labs: Post-reaction sample cleanup and standard solvent stripping.
Botanical Extraction Facilities: Low-temperature isolation of fragile terpenes, essential oils, and plant extracts (ideal for hemp and botanical oil refinement).
Educational Labs: Practical chemistry demonstrations and undergraduate student training due to its transparent layout and simple interface.
Manufacturer Support for B2B Distributors
Direct Tiered Pricing: Ex-factory pricing structures scaled to order volumes, ensuring strong market competitiveness and healthy distributor margins.
OEM & Private Labeling: Factory-direct placement of customer logos, specific corporate color housing schemes, and customized instruction manuals.
Local Electrical Localization: Configurable power supplies matched with regional plug standards (US, EU, UK, AU) to ensure immediate plug-and-play compliance.
Validated Export Packing: All glass structures are nested in custom-molded high-density foam inside heavy-duty multi-layer cartons or export-grade wooden crates to eliminate transit breakage.
Global Warranty & Support: All units come with a 1-year warranty on non-consumable parts and lifetime factory technical support to minimize your post-sale service burden.
Factory Quality Control Protocols
To minimize international return rates and warranty claims, every single unit passes through five mandatory testing stations before packaging:
Drive Motor Bench Test: 48-hour continuous rotation test to check for bearing noise, heat generation, and vibration.
Dielectric Safety Test: Electrical insulation and grounding verification matching standard global regulatory codes.
Thermal Calibration: Multi-point sensor verification to ensure the heating bath holds temperature within ±1 ∘C.
Vacuum Decay Test: System is pumped down and sealed to verify the PTFE/FKM gaskets maintain pressure without leakage over time.
Glass Polarized Light Inspection: Optical check of all borosilicate components to catch internal material stress lines or micro-fractures.
FAQ
Q: What specific solvents can be used with this system?
A: Thanks to the premium Borosilicate 3.3 glass and PTFE seals, the system handles most standard laboratory solvents, including ethanol, methanol, ethyl acetate, acetone, n-hexane, and chloroform.
Q: What is the main maintenance requirement for this unit?
A: The main maintenance point is cleaning and occasionally regreasing or replacing the PTFE/FKM vacuum seal ring. Over time, exposure to harsh solvent vapors will cause natural wear on any seal. We provide spare seal kits free of charge with bulk distributor orders.
Q: Can you supply this as a complete turnkey kit?
A: Yes. Upon request, we offer a fully integrated solution including the benchtop rotary evaporator, a matching oil-free vacuum pump, and a cooling chiller. Contact our team to get a tailored package quote.
Q: How do you handle custom branding (OEM) orders?
A: We can print your logo directly onto the chassis, match specific corporate color requirements for the housing, and customize the packaging/manuals. Contact our sales team today to get a free digital mockup with your logo and discuss our flexible MOQ options.
