Instruments in the standard LC series are also available with an optional “S” configuration (LCS) for use with some corrosive liquids. In the basic configuration, we upgrade the elastomers to FFKM. Some corrosive liquids require 316L stainless steel, and in this case we can upgrade the valve (type PCA) and flow body to 316L for full-scale flow ranges of 500 ccm or less.

Direct Flow Control for Microfluidics
Control flow rates as low as 0.01 ccm (10 µlm) directly without the need for pressure control over the fluid headspace. Fast-acting valves ensure your flow rate stays where you set it, even as temperature or pressure changes.
Liquid Product Dispensing
Dispense liquid products over a wide range of flow rates with the optional Precision Dispensing Package. Rapid valve response accommodates changing flow requirements and short dispensing periods. Digital feedback from PLC or PC allows realtime changes to maintain optimal process conditions.
