ChemStar® Dry

Product catalog summary

Overview: The ChemStar® Dry is a revolutionary oil-free vacuum system designed for deep vacuum chemical applications. It integrates a proprietary vacuum blower with patented PTFE diaphragm technology, offering a chemical-resistant alternative to traditional oil-seal pumps.

Key Features:

Oil-Free: Eliminates oil back-streaming, maintenance, and disposal, ensuring a cleaner workplace and contaminant-free samples.
Chemical Resistant: Capable of pumping corrosive vapors and gases, thanks to PTFE and proprietary coatings.
Plug and Play: Features patented software control with auto speed adjustment from atmospheric pressure to 0.05 torr, and a self-cleaning function to maintain performance.

Applications: Suitable for use in Schlenk lines, freeze dryers, vacuum ovens, glove boxes, and concentrators.

Benefits:

Time-Saving: Increases productivity by eliminating oil-related maintenance and extending maintenance intervals with a self-cleaning function.
Environmentally Friendly: Avoids oil disposal issues and contamination, eliminating oil misting and odors in the lab.
Reliability: Durable and repeatable vacuum performance with a robust chemical-resistant mechanism and vapor-load compensation.
Space-Saving: Compact design allows flexible installation options, including under-counter setups.

Technical Specifications:

Pumping speed: 150 L/min (9 m3/h) at 60 Hz and 2 torr.
Ultimate vacuum pressure: 5x10-2 torr (7x10-2 mbar).
Inlet/Outlet Connection: NW 25.
Dimensions: 18 x 8 x 18 inches; Weight: 50 lbs.

Accessories and Recommendations:

Use of a cold trap is recommended for high vapor load applications to extend service intervals.
Red rubber vacuum hoses are recommended over PVC or silicone due to chemical degradation concerns.

Technical Features Pumping speed 100 Intake pressure pa (mbar) | iaphragm vacuum pump D Intake Pressure (mbar) | peration principle O ChemStar Dry How it works: ChemStar Dry pumps quickly down to the working pressures for most evaporative operations (10 to 0.8 torr). It is in this range that ChemStar Dry creates maximum flow for high performance evaporation – clean, fast, and thorough. There is no oil, and the system automatically maintains and protects itself for repeatable robust performance. Pumping speed, 60 Hz at 2 torr Ultimate vacuum pressure Inlet-/Outlet Connection
