• Transparent cover with nozzle (made of acrylic)

♦ Used in combination with UT-3010 and 4000 series as a vapor trap for aqueous samples.

♦ The inside of the trap chamber is visible at all times without releasing the vacuum.

♦ The nozzle section can rotate 360°, allowing connection without applying bending stress to the vacuum hose.

♦ Equipped with a cover retainer to prevent the cover from falling off the equipment after pressure release.

♦ When used in combination with the optional trap monitor, the system can alert you with an alarm when the trap liquid reaches saturation.

 

• Cover with nozzle (made of stainless steel)

♦ Used for vapor trapping of aqueous samples in combination with UT-3010 and UT-4000 series.

♦ Equipped with a cover retainer to prevent the cover from falling off the equipment after pressure release.

♦ This cover is not transparent, so the inside of chamber is not visible during operation.

 

 

• Glass condensers

♦ Used to trap acid and organic solvent vapors in cold trap.

♦ Made of highly durable glass resistant to low temperatures, capable of withstanding environments as cold as -100°C.

♦ In low boiling point solvent glass condensers, the vapor first passes through the coiled tubing, increasing the contact (heat exchange) area with the low temperature area and improving recovery efficiency.

♦ High boiling point solvents and solvents whose freezing points exceed the trap temperature cannot be used as they may freeze and clog the coiled tubing.

A nozzle cap is installed at the piping connection between the glass condenser and the vacuum hose, making it easy to connect to the vacuum hose. The nozzle cap is made of PP and the O-ring is made of Perfluor. It has excellent corrosion resistance.

♦ Glass condenser set C consists of (glass condenser, pole, clamp, muff, PVC chamber cover)
