Lehman Scientific began business in 1985 by refurbishing
and reselling electronic test equipment and laboratory instruments.
As the years passed, we began selling more and more laboratory
instruments. In 2005, Lehman Scientific became Lehman Scientific,
LLC and moved into our own 16,000 sq. ft. building. While cleaning
out some storage rooms, we came across a few microwave components.
We no longer have the signal generators and network analyzers
required to fully test the components, so, we are selling them
as "subject to your test", and at very attractive prices.
The microwave parts appear to be in good condition, but you have
10 days after receipt to test them. They are returnable if they
do not meet your expectations.
