Where to buy a refurbished HPLC ?

First of all, what is a refurbished HPLC? This is a used HPLC which is checkout, cleaned inside and outside and repaired. So the HPLC is fully checked and all necessary parts are replaced.
You can say, a refurbished HPLC is like new. The best thing is.... you buy it much cheaper than a new system.

Refurbished HPLC is better for our environment 

When you decide to buy a refurbished HPLC, the factories doen not have to produce many new systems, which results in, savings of raw materials. 

What is HPLC?

First of all.... HPLC stands for High Pressure Liquid Chromatography. Liquid chromatography is performed with a HPLC system. The moving phase (eluent) is pumped under high pressure (up to 200 bar) through a highly packed column.

By means of high pressure and good contact with the stationary phase, a relatively high separation speed and a very good resolution are achieved. The running time can vary from 5 to 60 minutes for the measurement of one sample with HPLC.

Refurbished HPLC is not the same as used HPLC

Be critical, when you decide to buy a refurbished HPLC. There are many suppliers who sells  chromatography instruments, which are for sale as reconditioned (refurbished) or used. 

Refurbished is when an instrument is completely checked and where necessary, parts are replaced with original ones.  

Used is when an instrument is only cleaned at the outside and in working consition. So it is possible that the instrument has parts,  which are old and need to be replaced within a short period of time.
