• Model VOS-452SD and VOS-602SD
• New design for a better operability and reliability enabling less scattering and less contamination of samples
• Two sizes of chamber capacity are available for a wide range of applications, 91L and 216L
• Prevents contamination by suppressing scattering of powder and fine particles inside the chamber when vacuum release occurs
• Prevents contamination by suppressing powder and fine particles scattering in the chamber
♦ The anti-scattering plate is installed at the bottom of the chamber. This plate suppresses scattering of powder samples at the time of vacuum release, thereby preventing contamination. The powder sample scattering control capability can be further improved by attaching the slow leak tube.
• Bright, easy-to-read 4.3-inch color LCD digitally displays vacuum level
♦ The bright, easy-to-read 4.3-inch color LCD display improves operability and visibility. The screen digitally displays not only the temperature inside the chamber, but also the vacuum level in 1hPa units.
• Supports validation. Temperature measurement is possible during decompression
♦ Two standard sensor ports are equipped on the top part of equipment, allowing temperature measurement even in a vacuum. (Sensors and recorders are optional.)
Note: Continuous operation for more than 24 hours is not possible when sensors or other devices are inserted.
• Equipped with a slide base stand for oil rotary vacuum pump
♦ Model VOS-602SD is equipped with a dedicated stand. The slide base stand makes it easier to change the oil of the oil rotary vacuum pump.
• Our uniquely designed handle with no protrusions
♦ The handle features our unique design, allowing for easy opening and closing while ensuring secure fastening without the need for excessive force, eliminating concerns about vacuum leaks. Additionally, since the handle does not protrude, there is no risk of clothing or other items getting caught, ensuring safe and comfortable use.
• Easy operation from the front of equipment
♦ The variable independent overheat protector is installed on the front, preventing setting oversights and operational errors. Checking the set temperature is also easy. The valve operation is simple, requiring just a twist to open or close.
♦ The open/close status can be easily checked at a glance. When attaching the included slow leak tube to the leak port, even if the valve is fully opened during vacuum release, air will not rush in all at once. Additionally, by installing the included filter, dust is effectively blocked.

• Other devices required for decompression, trap, samples and piping connections
• Transparent cover with nozzle (made of acrylic)
♦ Used in combination with UT-3000 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.
• Cover with nozzle (made of stainless steel)
♦ Used for vapor trapping of aqueous samples in combination with UT-3000 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 tube, increasing the contact (heat exchange) area with the low temperature area and improving recovery efficiency.
