HERMOstar (Intelligent microplate annealing) THEMOstar is a high performance microplate incubator and orbital shaker for up to four microsamples. It can be used for any enzyme or cell based assay that requires homogeneous and controlled incubation and/or efficient mixing.

Microprocessor controlled heating plates above and below the microplates ensure outstanding temperature accuracy and uniformity throughout the plate, providing a constant temperature of up to 56°C with a wide range <0.6°C.

Temperature, shaking speed and incubation time are easily programmed via the keypad and all status parameters are displayed on the LCD in real time.

Microplate Stacker Microplate Stacker is designed to optimize microplate handling and increase workflow and throughput. Its compact base allows easy integration with BMG LABTECH microplate readers and provides rapid loading, unloading, repackaging and continuous loading of up to 50 microsamples. Stacker can accommodate all types of microplate formats and is designed to read barcodes from multiple locations on the microplate.

The best choice for medium throughput screening operations, Microplate Stacker allows users to focus on running tests, not managing plates.

Plate LVis Low volume measurements

BMG LABTECH’s exclusive LVis plate is a low mass microplate that combines a cuvette slot and optional performance testing features.

With 16 micro-drop wells, the LVis Plate is ideal for quick and easy low-volume measurements of DNA, RNA, protein samples or spectroscopic scanning. Left and right-handed support for 8-channel pipettes makes multi-sampling simple and easy. What’s more, the surface is easy to clean, so you can quickly prepare for your next measurements.

The horizontal cuvette position allows standard rectangular cuvettes to be measured for rapid, complete spectrum analysis of individual samples for kinetic studies or for rapid experiments.

The LVis plate can also be equipped with an optical density (OD) filter and NIST traceable holmium oxide for quality inspection of all spectrometer-based instruments.

Filter Filters for a wide range of applications

The filter is made of a multi-layer substrate, on which film coatings with different refractive indices are applied. In general, filters can range from 240 nm to 850 nm with a wavelength of 10 nm and typically have a blocking power of six optical density units (OD), or 999,999 parts per million. Thus, a filter has the ability to block unwanted stray light down to 0.0001%.

BMG LABTECH works closely with each customer to ensure optimal filter selection for their particular test. In cases where standard filters are not sufficient, filters optimized for testing for specific applications and tailor-made solutions are also available, as well as special filters with extremely narrow bandwidths (2 or 3 nm) or large (50 or 100 nm). For the PHERAstar platform, our customers can choose from a wide variety of experimentally optimized Optical Modules.

Review sheet The intended use of the Evaluation Sheet is to validate the optical functionality of the BMG LABTECH microplate reader for quality control and/or certification (IQ/OQ) purposes in GLP compliant environments. This plate is compatible with all of the BMG LABTECH readers listed below and is designed to simplify fluorescence intensity, luminescence and absorbance quality tests, saving time. and avoid using fluid standards.

Unlike liquid tests that are affected by pipetting or handling errors, the Evaluation Plate reduces sources of error as it is equipped with NIST traceable absorbance reference filters and solid standards for fluorescence. optical and luminescent.

The workflow for test measurements and data reduction is performed automatically by the software, which also reports on the achievement or failure of the validation parameters.
