Separations Products & Reviews

This ASPEC system for positive pressure solid phase extraction (SPE) maximizes throughput by processing up to four samples in parallel.

The ASPEC Positive Pressure Manifold uses positive pressure to improve reproducibility and recovery for solid phase extraction (SPE) applications. 

When a smaller, low-flow HPLC system is necessary, look to the VERITY® 241 HPLC System.

Mass-directed detection is now available for your lower capacity VERITY 241 HPLC system with the addition of the VERITY 1900 MS Detector.

Take your VERITY 271 HPLC system a step further with the power of mass-directed detection by choosing the VERITY 1900 MS Detector. 

When large capacity and throughput are needed, the VERITY 281 HPLC systems provide the answer for semi-preparative and preparative purifications.

With the chip-based VERITY 1900 MS Detector, mass-directed detection is now available for your high capacity VERITY 281 HPLC system.

The VERITY Compact CPC System combines a PLC Purification System with a centrifugal partition chromatography (CPC) system for high-level target compound purification.

The VERITY Compact CPC-MS System allows you to perform mass-directed purification of target compounds by centrifugal partition chromatography (CPC).

The VERITY Compact LC System simplifies and streamlines compound purification by integrating preparative HPLC and flash chromatography in one customizable instrument making it one of the most flexible automated purification systems available.

The VERITY® Compact LC-MS System combines the PLC Purification System with the VERITY 1900 MS Detector to provide a compact, easy-to-use, all-in-one instrument for mass-directed purification of target compounds by preparative HPLC and flash chromatography.

The VERITY® GPC Cleanup System is an ideal solution for post-extraction cleanup of high-molecular weight interfering substances from environmental samples, food products, and animal tissue prior to analysis using gel permeation chromatography (GPC). Removal of these contaminants leads to more reliable results, fewer sample repeats, and less downtime for downstream chromatography instruments.

The VERITY® GPC Cleanup System is an ideal solution for post-extraction cleanup of high-molecular weight interfering substances from environmental samples, food products, and animal tissue prior to analysis using gel permeation chromatography (GPC). Removal of these contaminants leads to more reliable results, fewer sample repeats, and less downtime for downstream chromatography instruments.

This VERITY® oligonucleotide purification system offers a single, automated HPLC system for the purification, analysis, and desalting of reagent-grade synthetic oligonucleotides in one continuous run. The system seamlessly changes between preparative and analytical scales, saving time and equipment space, while built-in error handling allows for unattended operation.

The VERITY® 3240 High Pressure Binary Gradient Pump is designed for semi-preparative to preparative purification. It provides an economical and compact pumping solution for preparative purification on 10 to 50 mm ID columns thanks to its large dynamic flow range up to 150mL/min. and pressure up to 420 bar (6090 psi).
