Experienced Centrifuge Dealer

New Life Scientific is no stranger to centrifuges. Over the past four years we have
dealt in and worked on a wide variety of benchtop and floor centrifuges from the
top manufacturers, including Eppendorf, Beckman, and Sorvall/Thermo.

You can have confidence in our technical evaluations and our warranty knowing
that we have actual in-house technicians who inspect, test, service, and repair
centrifuges. After their examinations and being cleaned inside and out, they often
leave our shop meeting manufacturer specs.

When you buy from us, you’re not just buying a centrifuge. You also gain a
resource for after-sales support for any questions or issues that may arise, even
after your warranty expires.

Built for the Laboratory Benchtop

Refrigerated benchtop centrifuges normally have the refrigeration system located
to the right of the chamber, however, the Allegra X-22R has the refrigeration
system located on the back of the chamber with ventilation on the top and sides,
giving it a width of just 18 inches (46 cm).

This design choice allows the centrifuge to not only fit into more narrow spaces,
but also sit comfortably against the wall, saving even more valuable space on
the benchtop.

90-Day Warranty for your Peace-of-Mind

We realize that buying pre-owned can be unnerving, so we include a 90-day
warranty on our equipment to protect you against any equipment failure or
defects. If anything goes wrong, our in-house support is only a phone call away.
