February / March 2012 Introducing the Source for High Quality Chromatography Glassware
Researchers have a source for high quality, chromatography glassware designed to provide convenience, economy and efficiency. Kimble Chase offers a portfolio of chromatography glassware that includes columns, tanks, sample vials and its unique solvent handling system, with Ultra- Ware®
reservoirs.
For preparative scale-up applications, chromatographers use borosilicate glass CHROMAFLEX® FLEX-COLUMN®
, or polypropylene DISPOSAFLEX® and chromatography columns. Columns are supported
with available fittings, flow adaptors and packing reservoirs. For analytical separations, Kimble Chase manufactures glass gravity columns in several configurations along with reservoirs and adaptors. For custom chromatography columns, the Custom Glass Shop at Kimble Chase offers design and fabrication services.
Kimble Chase offers optically clear, ruggedly durable TLC Developing Tanks in several configurations, including rectangular and cylindrical. Microcaps are ingenious borosilicate glass capillary tubes designed for precise TLC plate spotting. Other accessories include TLC reagent sprayers, a plate streaker and labelling templates.
Kimble Chase offers Ultra-Ware HPLC Mobile Phase Handling Systems to improve retention-time reproducibility and baseline stability by reducing contaminant background noise levels. These airtight and chemically resistant systems eliminate exposure to ambient air contaminants while maximising the effectiveness of helium sparging. The plastic safety coating used on Ultra-Ware reservoirs minimises photochemical degradation of the mobile phase by blocking virtually all ultraviolet radiation below 385 nanometers. The systems provide completely integrated filtration, sparging/degassing and delivery of solvents. Reservoirs, with their patented conical bottoms, are available in sizes ranging from 250mL to 20 litres.
For chromatography sample management, Kimble Chase offers chromatography and sample storage vials in various styles, with attached closures, printed volume measurement lines, and closures with multiple cap and liner combinations in a choice of materials. Kimble Chase s vials are manufactured in USA-based, ISO-9001 compliant facilities.

No relevant progresses in GC autosampler technology have been introduced for many years. HTA reinvents the market by introducing a new GC autosampler lines: HT3000A (autosampler) and HT3100A (autoinjector). Innovative functionalities, easiness of use and extraordinary performance distinguish these new autosamplers and place them at the forefront of the GC autosampler market.
HT3000A is the most compact autosampler on the market while offering top-class sample capacity: 121 positions for 2ml vials are available in the standard version.
It is the first autosampler in the world featuring a touch screen display that provides easier system accessibility and usability, simplifying instrument control, also by inexperienced users.
HT3100A offers automation for processing up to 15 samples, so it represents the ideal solution for labs that run small sample batches and care about reproducibility and reliability.
Quick set of autosampler parameters can be done by the free PC control (HTA Autosampler Manager) provided along with HT3100A, while all the routine operations can be managed by its dedicated keypad. To run the analysis, simply push the START button and all the samples in the rack will be automatically processed, without the need for further assistance by the operator.
HT3000A and HT3100A fit all GC and GC/MS systems available on the market, more or less recent models, regardless of the GC brand. They can be configured serving up to two injectors, with only one tower, in the most of the supported GC. Furthermore, they can be easily moved between GCs, also of different brands, when the workload changes.
Moreover, thanks to their versatility, they can use different kind of syringes with volume from 500 nanoliters to 100 microliters, to suit all applications.
In fact they can handle all the sampling techniques, even the most sophisticated: internal standard technique (also known as sandwich injection), multi-phase, ambient headspace, priority injection, nanoliter injection and much more.
They are also provided with an outstanding solvent capacity allowing longer unattended operations and offering double wash step capability for superior analytical performance.
Finally HT3000A and HT3100A are the fastest liquid autosamplers available on the market: the injection is performed in less than 100ms For more information please visit
