Shimadzu Total Organic Carbon Analyzer (TOC-VCPH) and Shimadzu ASI-V Autosampler

Note: This instrument is owned by a researcher and not intended for general use. Please contact Reiner Giesler for further information.

Specifications (see manual for details):

Combining the ASI-V automatic sample injector with a TOC-V Series analyzer creates a fully automatic analysis system
Three sample vial capacities are available
Select the sample vial and sample rack to suit the analyzed sample.
24 mL vials x 93
40 mL vials x 68
125 mL vials x 24
All three vial types have a well-sealed septum that can be easily replaced with the screw cap
The sampling needle is optimized for sample extraction from highly sealed vials and for sparging
Changing analysis conditions or adding sample vials during analysis is simple
System operation and carrier gas flow can be automatically stopped on completion of measurements
Creating multiple calibration curves and selecting the optimal curve for samples with significantly differing concentrations allows these samples to be analyzed in a single run
Rinsing both external and internal surfaces of the sampling needle prevents carryover between samples

Rainin Pipettes EDP3 Plus

Note: This instrument is owned by a researcher and not intended for general use. Please contact Reiner Giesler for further information.

Specifications (see manual for details):

The advanced microprocessor-controlled technology avoids pipetting errors and ensures highest precision
EDP3 makes piston movements operator independent, providing consistent accuracy, user-to-user, sample-to-sample
Ultra-light one-hand tip ejection
Autopace for auto-dispense plus versatile modes
