This listing is for a 90-DAY-WARRANTY in Great Cosmetic & Operational Condition: PERKIN ELMER SERIES 200 LC PUMP ISOCRATIC BINARY MICRO as can be seen in the pictures.
This unit came from a Federal University, has been fully tested and is 100% Operational and that is why we are Guarantee & Offer a 90-DAY-WARRANTY on it!!!
IMPORTANT: AS CAN BE SEEN IN THE PICTURES THE TOP PART SHOWS PAINT PEELING, NOTHING THAT AFFECTS OPERATION WHATSOEVER BUT WE FEEL IT IMPORTANT TO MENTION AND TO SHOW IN THE PICTURES!

Series 200 LC Pumps
Isocratic, Binary, Quaternary and Micro
Flow – Built to Withstand the Test of Time
Our customers tell us that PerkinElmer’s pump design offers the best flow rate
precision. Here’s why. . .
A Automated Solvent Maintains a continuous and constant flow with each pump stroke using patented real-time
Compensation blending compensation, which accounts for and meters different volumes according to the
solvent shrinkage that occurs with mixing. This same principle corrects for solvent
compressibility changes.
B Minimal Pulsations Minimizes pressure pulsations due to high-speed retraction of delivery piston with every
stroke (65 msec.)
C Low Mixing Volume* Provides high-efficiency solvent mixing resulting from extremely high turbulence inside the
pump when the pump transfers the next increment of solvent from the low-pressure piston
to the high-pressure piston at a high flow rate (100 mL/min).
D No Air Bubbles Eliminates cavitation or bubbles as a result of the unique, patented design that provides
positive transfer of the next increment of solvent under pressure rather than vacuum refilling,
as is typically done with other pumps. In the schematic, the delivery chamber is about to be
positively refilled from the metering chamber.
E Superior Low Flow-Rate Operates efficiently even at lower flow rates because of the double-check valve design that
Performance prevents solvent backflow on each delivery stroke.
Time-proven design
keeps your lab going
PerkinElmer pumps are built to
keep running. We ensure that the
pump going into your laboratory
is fully-tested and calibrated to
ensure reliable, trouble-free operation all day, every day. Our
quality assurance laboratory reports that the typical Mean Time
Between Failure (MTBF) is a minimum of 4400 hours – that’s two
years of continuous operation with
no failures of any kind (8 hours a
day, 5 days a week). PerkinElmer
pumps are still the lowest maintenance pumps on the market
with the most rugged design.
