Creating a controlled environment requires precision at every connection. PolyLab's Dessicator, Tubing and Connectors provide that precision, ensuring that your vacuum holds and your fluids flow exactly as intended. Our vacuum dessicators are frequently cited as the top rated for their ability to maintain a seal over months of use, thanks to precision-ground sealing surfaces. For labs building custom manifolds, our range of connectors offers the best selection of sizes and materials to suit any gas or liquid. We understand that a leak in a vacuum line can ruin an experiment, which is why our tubing and fittings are manufactured to exacting standards. Connect your lab with PolyLab and ensure that your controlled atmospheres stay controlled. It is the best connection you can make and the top rated by engineers worldwide.

Frequently Asked Questions Stop Cocks

PolyLab vacuum dessicators are designed to hold vacuum up to 740 mm Hg for 24 hours without greasing, thanks to precision-ground sealing surfaces and silicon O-rings. They are suitable for most laboratory vacuum applications, including drying hygroscopic samples and storing moisture-sensitive materials.

PolyLab offers various tubing types including platinum-cured silicone for highest purity, PVC for general purpose, Tygon for chemical resistance, and Viton for aggressive solvents. Each type is optimized for different chemical compatibility, temperature ranges, and flexibility requirements.

Tubing is specified by inner diameter (ID) and outer diameter (OD). Choose ID based on the barb size of your connectors or the flow rate required. Choose OD based on the compression fittings used. PolyLab offers a wide range of sizes from 1mm to 25mm ID to suit all applications.

PolyLab dessicators with polycarbonate domes and polypropylene bases are autoclavable at 121°C. However, remove the stopcock and O-ring before autoclaving as these components may have different temperature tolerances. Allow to cool completely before reassembly.

Our connector range includes straight connectors, Y-connectors, T-connectors, cross connectors, L-connectors, barbed fittings, luer fittings, and quick-disconnect couplings. They are available in various materials including polypropylene, polycarbonate, and PTFE for different chemical compatibility needs.

Cut tubing ends squarely, push firmly onto barbed fittings ensuring full engagement, and use hose clamps for critical applications or higher pressures. For compression fittings, follow manufacturer instructions for tightening. PolyLab barbed connectors are designed for secure grip without clamps for most applications.
