- Model BLC-20P HPLC - Isocratic Semi-Preparitive



The BLC-20P from Buck Scientific is an isocratic, semi-preparative HPLC system with variable wavelength detector. The BLC-20P can be programmed with a flow rate as high as 40 ml/min. The pump head can also be swapped out for our standard 10 ml/min analytical pump head.

  • Great for purification of expensive samples
  • Compound isolation & purification from complex mixtures
  • Therapeutic agent production
  • Chiral separations
  • Protein purification
  • Easy Solvent Changes

Autoprime one-button purging makes it easy to prime or purge the pump.

The digital stepper motor technology and the proven sin- gle piston design perform like the most expensive pumps at a fraction of their cost. The operating cost is lower too, due to the simplicity of the design and fewer number of parts required.

The patented low dead volume pulse damper and rapid refill make this single-piston pump virtually pulse-free. It meets the requirements of the most demanding detectors.

Flow rates from 0.001 to 5 mL/min.; 0.01 to 10 mL/min.; or 0.1 to 40 mL/min. are available.

Available in either traditional 316 stainless steel or bio- compatible PEEK (polyetherether ketone) for metal sensitive applications. Choose the material best suited for each application.

Reduced Maintenance
Seal life is dramatically extended by actively flushing the back of the primary seal with a flushing solution. The re- sult is less down-time and reduced operating expenses. The self-flush is automatic; just change the flushing fluid weekly. Seals can be changed in five minutes without tools.
