Validating Labconco equipment using an RS232 port

Validating lab equipment for IQOQPQ can easily be done using an RS232 port and PC. Using Hyperterminal with Windows® '95 and up to Windows XP, validation can be of little cost to the user.

Since Windows Vista and Windows 7 no longer include Hyperterminal, software, such as Labtronics Collect XL can be purchased to allow transfer of data directly into Excel or another program of your choice.

Labconco offers two cables, a 9 pin or a 25 pin, depending on the serial port on your PC. If the PC does not have a serial port an adapter can be used to connect the RS232.

Many Labconco products include a RS232 standard including Protector® Glove Boxes, Purifier® Logic® Biosafety Cabinets, Fume Hood Guardian™ 1000 Air Flow Monitors, FlaskScrubber® Vantage® Glassware Washers and FreeZone® Freeze Dry Systems.
