About this item
Permanent UV Protection with the Amber Evaporator Receiver
Protecting light-sensitive materials requires specialized dark equipment. An amber rotary evaporator flask is essential for this critical task. Standard clear glass cannot stop harmful UV light below 400 nm. Our brown glass actively prevents the rapid degradation of halogenated solvents. It also protects valuable conjugated organics during your extraction phase. We manufacture this receiver using premium iron-oxide doped Boro 3.3 glass natively. This material meets rigorous global safety standards for laboratory use.
You can review exact glass durability specifications on the ASTM International standards hub. The dark tint is permanently baked right into the glass melt. Because of this, the color will never wash or scratch off. Your sensitive natural compounds will remain entirely safe from room lighting. Also, explore our reliable Lab Glassware collection to find matching distillation tools quickly.
1Extreme Thermal Shock Resistance
An amber rotary evaporator flask must handle extreme temperature shifts safely. Our Boro 3.3 formulation provides excellent thermal stability for daily lab work. It easily withstands a rapid temperature differential of 200°C (392°F). You can move it from a hot water bath directly to ice. It operates continuously at 450°C (842°F) without any structural failure. In short, it matches the high durability of standard clear laboratory glassware completely.
2Precision Ground Vacuum Sealing
A reliable receiver must fit your existing distillation equipment perfectly. We offer these flasks with precision-ground standard taper joint connections. You can easily choose from 19#, 24#, or 29# neck sizes. They mate securely with most major rotary evaporator brands on the market. These precision-ground glass joints guarantee a perfectly tight vacuum seal always. A strong vacuum is absolutely critical for efficient solvent removal processes.
3Smart Pear-Shaped Geometry
Physical design plays a huge role in final product recovery efficiency. This vessel features a classic bulbous pear-shaped lower geometry structurally. It concentrates your collected liquid distillate right at the very bottom. This smart shape makes physical decanting much easier for researchers. It also dramatically minimizes residual wall-film loss after emptying the flask. We provide eight distinct volume capacities to match your specific batch sizes perfectly.
Core Capabilities of the Brown Receiver
🛡️ Permanent Tint
The iron-oxide color is built directly into the borosilicate melt. It easily survives hundreds of intense acid wash cycles without fading.
🛑 99% UV Block
Filters out harmful ultraviolet radiation and cuts visible light transmission by 85%. It keeps your sensitive natural compounds entirely safe.
⚖️ 8 Capacities
Choose the perfect size for your exact daily workload. We offer volumes spanning from 25ml (0.85 oz) to 2000ml (67.6 oz).
🌡️ Autoclave Safe
Fully compatible with standard steam sterilization protocols. You can safely autoclave the flask repeatedly at 121°C (250°F) securely.
Upgrading to a brown receiver instantly protects your total product yield. It is a very smart investment for any serious analytical chemistry lab. You will stop losing valuable synthetic compounds to unwanted photobleaching entirely. Pair this amber rotary evaporator flask with our reliable Lab Stirring & Heating systems. You can build a completely safe and highly efficient evaporation workstation today.

FAQs
Q1: When should I use amber glass instead of clear glass for my rotary evaporator?
A1: Use amber (brown) receiving flasks whenever your distillate contains light-sensitive compounds such as chlorophyll, carotenoids, retinol, tocopherols, transition-metal complexes, conjugated dienes/polyenes, or any compound that discolors, degrades, or polymerizes when exposed to ambient laboratory lighting. If your product is stable under normal light conditions, clear glass is acceptable and offers slightly better visual monitoring of fill level during runs.
Q2: Does the amber color affect thermal properties compared to clear borosilicate glass?
A2: No measurable difference. The iron oxide additive that produces the amber color does not alter the coefficient of thermal expansion, softening point, or thermal shock resistance of the base Boro 3.3 borosilicate composition. The amber flasks tolerate the same temperature ranges (up to 450 °C continuous) and autoclave cycles as their clear counterparts from the same manufacturing line.
Q3: Which capacity and joint size combination do most labs choose?
A3: The most popular single configuration is the 250 ml / 24# variant, which matches the default receiving flask supplied with most mid-range rotary evaporators (Buchi R-100/R-200 class, Heidolph Hei-VAP, etc.). If you run larger batches (500+ ml distillate), step up to 500 ml or 1000 ml with a matching 24# joint. The 29# joint size is typically selected for larger industrial-scale units with oversized condenser adapters.
Q4: Can I use this amber flask as the main evaporation flask, or only as a receiver?
A4: Technically yes, but with caveats. These pear-shaped flasks are optimized as receiving vessels downstream of the condenser. Using them as primary boiling flasks is possible if the joint size matches your drive motor adapter and bath opening, but the bulbous pear shape creates uneven heat distribution when immersed in a heating bath compared to a round-bottom design. For maximum safety and efficiency, use round-bottom or flat-bottom flasks on the evaporation side and reserve these amber pear flasks for receiving duty where light protection matters most.
