215 Direct-Inject Liquid Handler/Injector :: Mandel Scientific Company Inc. ::

215 Liquid Handler/Injector

Single-probe, "workhorse" liquid handler delivers a robust performance for fast and accurate direct injection onto HPLC or LC/MS systems. Suitable for a wide variety of applications, with the ability to pierce thick septa. Performs injection, fraction collection and re-injection of collected fractions on one platform.

Features:

Versatile, large-bed liquid handler accommodates more than 330 racks to hold virtually any type of sample vessel
Add injection capabilities with the 819 Injection Module; configure with two 819 Injection Modules for increased throughput or for analytical and preparative injections
"Make-before-break" stator and large-bore rotor seal prevent pressure spikes from injection at high flows
Numerous custom software and rack configurations to meet the demands of your applications
New spring-loaded probe is ideal for low- and sub-microliter liquid handling applications, allowing "touch-off" deposition without damaging the substrate or degrading the sample

Applications:

Analytical analysis and preparative-scale purification of synthetic and biological compounds
Semipreparative compound purification and identification as part of Gilson’s LC/MS Autopurification System
Multidimensional separations with Solid Phase Extraction (SPE) for the preparation of protein digests for LC/MS/MS analysis
