TOPT-1L Glass Jacketed Reactor (Double glass reactor)

Scaling Up from Bench-Top: The TOPT-1L Compact Jacketed Glass Reactor

You know that awkward phase when your reaction works beautifully in a round-bottom flask but you need more material for proper characterization? I've been there too many times to count. The TOPT-1L hits that perfect middle ground - enough volume to generate useful quantities without committing to pilot-scale equipment that takes up half your fume hood.

Built from borosilicate 3.3 glass, this reactor handles temperature swings from -80°C to 200°C without breaking a sweat. The double-wall construction lets you circulate heating or cooling fluid independently while your reaction churns away inside, which is honestly a game-changer for anything exothermic or temperature-sensitive.

One-Liter Capacity for Small-Scale Synthesis Optimization

Here's why I reach for the 1-liter size constantly: you're not burning through expensive reagents like you would scaling up to 3 or 5 liters, but you've got enough product to run full characterization - NMR, mass spec, maybe even some biological testing if that's your thing.

• Process development work where you're tweaking conditions run after run
• Natural product extraction when you've only got limited plant material
• Teaching environments where students need real equipment experience
• Pharmaceutical synthesis optimization before committing to the TOPT-3L jacketed glass reactor or Glass Jacketed Reactor (Double Glass Reactor) TOPT-5L
• Crystallization studies where visual observation through clear glass is critical

The 10 kg weight means it's stable during vigorous stirring but still manageable when you need to relocate it. Runs on standard 110V/220V power - no electrician required.

Double-Wall Glass Construction for Temperature Control

The jacket design is where this reactor really shines. I've run Grignard reactions at -40°C and high-temperature cyclizations at 180°C in the same week - just swap your circulator and you're good to go. Connect it to a Cooling circulator Chiller LX-0400 for those reactions that need serious cooling power, especially when you're adding reagents that generate heat fast.

Chemical compatibility is excellent across most common solvents - chlorinated, ethereal, aromatic, you name it. The jacket pressure rating of 0.5 MPa gives you flexibility with different heat transfer fluids depending on your temperature range. Pro tip: use silicone oil for high-temp work and ethanol-water mixtures for cooling below -20°C.

Overhead stirring provides consistent mixing even with viscous slurries. I've handled everything from watery solutions to thick crystalline suspensions without the stirrer bogging down.

Ideal Bridge Between Test Tubes and Pilot Production

What makes this reactor essential in my lab is the clear scale-up path. Once you've optimized conditions at 1 liter, transferring to the TOPT-3L or TOPT-5L models is straightforward - same design principles, just bigger. Your heat transfer calculations, stirring rates, and addition times scale predictably.

Pair it with a Vacuum pump SHB-B95 or Vacuum pump SHB-III when you're doing distillations or need to pull vacuum during moisture-sensitive reactions. The multiple ports on top accommodate condensers, addition funnels, thermometer wells, and vacuum connections simultaneously. Make sure your condenser seals are tight during reflux - learned that lesson when I lost half a reaction to evaporation.

Cleaning between runs is straightforward with no hidden corners where residues hide. The visual monitoring capability lets you catch problems early - color changes, precipitation, phase separation - before they become disasters.
