ROTARY EVAPORATORS
305
Traps
Top Vapor Tube Traps The design of this trap provides for expanded volume for organic mixtures that have a tendency to foam excessively. • Inner vapor tube is ring-sealed at the top of the flask to prevent entry into the condenser • Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements
Bottom Vapor Tube Trap with Drain Holes Use where foaming is likely to occur and be drawn into the condenser. • The inner vapor tube features two, 4 mm drain holes at its base placed 180° to each other and 90° to the upper holes, allowing faster drainage of trap contents back into the evaporation flask • The modified joint on the 570265 series features a square bead for better sealing to rotary evaporator equipment • Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements

Self Washing Top Vapor Tube Traps This trap is designed to eliminate hold-up common to the round style of rotary evaporator traps. Tapered sidewalls permit continuous washing with condensed solvent while preventing vapor cooling points along the path of the condenser • • The upper stem has 4 large holes that allow solvent vapor to flow freely and help to make this portion of the trap easy to clean • The increased volume of the trap prevents “bumping” and keeps solvent out of the vapor tube • Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements
Fritted Bump Trap for a Rotary Evaporator This trap has a 40-60 micron porosity fritted disc sealed between the lower inner and top outer joint to prevent the contents of the flask from entering into the condenser in the event of bumping.
•
All traps have a Standard Taper 24/40 top outer joint
• Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements
