Titrator

OMNIS is capable of performing four fully automated analyses simultaneously, and can process up to 175 samples completely unattended. A patented Liquid Adapter makes reagent exchange contact-free and safer than ever. The new Metrohm titration platform is intuitive to use, as the entire hardware is graphically represented in the user interface. Custom systems can be configured by dragging and dropping the icons on the desktop or on a touchscreen interface. OMNIS was developed to focus on the sample: Whatever methods are necessary to analyze a sample, OMNIS collects the results and connects them to the sample. This feature saves time and effort, allowing the results for the parameters of interest for each sample to be shown in a single report. OMNIS addresses the needs of small and large laboratories alike—the platform is modular and can be expanded from a stand-alone titrator to a powerful system that includes automation.

Automation-Ready Blowdown Evaporator

The Ultravap Levante is a nitrogen-blowdown evaporator used for removing chromatography solvents such as dichloromethane, acetonitrile, methanol, and hexane. It can be operated from an in-house supply of nitrogen/clean dry air or from a gas cylinder. The Ultravap Levante comes with an RS232 connection and a remote command set, enabling it to connect to and be operated from most commercially available robotic liquid-handling systems. In addition, it is equipped with full-color touchscreen graphic displays, an integrated auto-ranging power supply, and built-in solvent fume venting. Offering multistep ramped programming with full alphanumeric program naming, it can automatically handle even complex evaporation protocols effortlessly. Designed around a standard ANSI/SLAS plate "nest" to accept most microplate formats and tube racks, the Ultravap Levante can accommodate tubes up to 80 mm in height and allows the use of 2-dram vials, 1.5-mL HPLC vials, barcoded tubes in racks, and many other common formats.

TF3 System

The Postnova TF2000 is an advanced thermal field-flow fractionation (TF3) system that provides an efficient method of separating and characterizing complex polymer samples such as natural or synthetic rubbers, starches, and paints from approximately 10 kDa up to 100 MDa and more, in organic and aqueous solvents. The TF2000 uses a temperature gradient as the driving force for its separation of polymers and particles. This unique feature allows the separation of different materials having the same molar mass. Separation can be further optimized by the use of different eluents and various temperature programs. Unlike traditional gel permeation chromatography/size-exclusion chromatography separation, samples can be injected without prefiltration, allowing the characterization of complex polymer and nanoparticulate samples without any potential alteration and damage. The TF2000 also has no size-exclusion limit—even ultrahigh molar mass, branched, and crosslinked polymers can be separated, as well as gels, aggregates, and particles.

Pipettes

INTEGRA's VOYAGER II pipettes feature unique motorized tip spacing, enabling parallel transfer of multiple samples between labware of different sizes and formats. The tip spacing can be changed by the simple push of a button. Due to varying requirements in their sample processing, different labware vessels are typically used for sample storage, processing, and analysis tasks. Traditional multichannel pipettes were not designed to accommodate the wide variety of labware formats used today, because their tip-to-tip spacing is optimized for use with standard 96-well microplates. The VOYAGER II can adjust its tip spacing anywhere between 4.5 mm and 33 mm. Lab scientists choosing to download the new application guide can learn how to significantly reduce the hours they spend pipetting, and how to minimize transfer errors when pipetting liquids between tubes, vials, and microplates. Applications covered in the guide include screening compound libraries, genotyping, quantitative PCR, and cell seeding.

Benchtop-Scale Fermentation Systems

proSET is a range of benchtop-scale fermentation systems designed to provide an optimized cell cultivation solution for applications including the growth of sensitive and fragile mammalian and insect cells. Incorporating a large, color touchscreen panel with an intuitive software interface, these systems are very user friendly. The proSET One combines space-saving design with operational versatility and affordability. The heating system in the proSET One allows use of any fermentation vessel type up to 20 L. The fermentation temperature, antifoam, pH, and dissolved oxygen probe are all included in the standard package. Drawing upon its ability to accommodate vessels from 0.5 L to 20 L, the proSET Evo System enables productive cultivation of cell lines, including aerobic and anaerobic bacterial, yeast, plant, algae, fungal, mammalian, and insect lines. The proSET Parallel System allows you to run up to two thermostat-heating and two dry-heating experiments simultaneously.
