Graduated flasks
Volumetric flasks provide precise results in chemistry and pharmacy. They are not scaled, but have a single ring mark that is drawn all the way round the neck to avoid reading errors.
The narrow neck results in high setting accuracy. In addition, volumetric flasks have bulbous curves in the upper area so that any gas bubbles that form can escape from the solution more easily. However, if there are gas bubbles in the solution, the volumetric flask must be swivelled slightly so that the bubbles rise to the top. In addition to volumetric pipettes and burettes, volumetric flasks are therefore the most accurate volumetric instruments in the laboratory for analysis.
Blender bags, sterile, PE
The LABSOLUTE® blender bags made of high-quality pure PE are designed for safe and rapid homogenization of solid samples prior to microbiological and chemical analysis. The homogenising bags can be used in direct contact with food. They are available in three versions: without filter, with side fleece filter with a pore size of <250 μm or with a full-page fleece filter with a pore size of <280 μm....
Blender bags, BagSystem®
These gamma-ray sterilized bags have a high mechanical stability and ensure safety for the samples. The filters inserted in the bags filter the liquid during sample preparation (washing process) and retain sample particles.
BagLight®: Bag without filter, for all microbiological laboratory applications....
Laboratory mixer, BagMixer®400
For sample preparation with easily adjustable paddle system. The BagMixer ® is available in 3 sizes and blends all sample types prior to their microbial analysis. Thanks to their unique adjustable paddle system the blending chamber can be adjusted to the sample volume. Combined with the variable speed, a higher bacterial recovery rate is achieved. All BagMixer...
Cell disruption shakers Disruptor Genie® analog / digital
The patented Disruptor Genie
® provides a multi-directional action, which simultaneously agitates and vortexes at high speed, dramatically increasing cell disruption or sample resuspension efficiency.
- Dramatically increased sample disruption efficiency. Ideal for difficult glass bead procedures (Glass beads - please order separately), cell disruption/homogenisation of yeast, bacteria, plant and animal tissues and pellet resuspensions or anything that requires extremely violent, high-speed agitation.
- Patented multi-directional action simultaneously agitates and vortexes at high-speed producing greater yields in less time
- Hands-Free disruption of up to twelve 1.5ml or 2.0ml microtubes with timer from 0 to 15 minutes (Disruptor Genie® analog), 0 to 99 minutes (Disruptor Genie® digital) or continuous operation
- Performance comparable to expensive ultrasonic cell disruptors/homogenisers.
- Suitable for use in cold rooms or incubators
