Reagents for the detection of plant pathogens (viruses, bacteria, fungi and phytoplasma). Special equipment and disposables for the preparation of plant samples and liquid handling. Ready-to-use kits.
The rapid one-step assay AgriStrip, developed and manufactured by BIOREBA, is based on lateral flow immunochromatography and is very fast. The test has been developed to confirm the presence of a plant pathogen in samples with suspicious symptoms. Such a sample is homogenized and a few drops of the homogenate are transferred to a cuvette.
The strip is dipped into the extract and the result can be read within a few minutes. A positive result is seen as a colored band at the test line,whereas the colored band at the control line should always appear. Test strips can be kept as permanent records.
The performance of the test is very easy and there is no need for special laboratory equipment. Therefore, the AgriStrip is especially suitable when testing is required on-site, such as in greenhouses or fields.
The innovative rapid assay AgriStrip-magnetic, developed and produced by BIOREBA, is a lateral-flow immunochromatographic test based on an antigen-antibody reaction combined with Magnetic Bead Technology enabling the preceding enrichment of the antigen. A plant extract is first incubated with magnetic beads coated with pathogen-specific antibodies. These beads are then separated from the extract with a magnet and re-suspended in a small volume of running buffer. Finally, a strip is inserted and the concentrated beads migrate upwards through the strip and brown colored lines will become visible.
Both test and control lines become visible with positive extracts (containing the pathogen), whereas negative samples produce only the upper control line. Intense coloration is reached within 10-20 min and the results can be registered.
The performance of the test is very easy and there is no need for special laboratory equipment. The AgriStrip-magnetic is especially suitable when testing is required on-site, such as in greenhouses or fields.

Gellan is a water-soluble bio-polymer used as a gelling agent. The low acyl type forms hard gels at low concentrations in the presence of an electrolyte.
• forms gels which are mechanically robust
• forms gels which are transparent and colourless
• forms gels which are thermally reversible
• forms gels which do not melt at high ambient temperatures
• forms gels which do not exhibit syneresis
• is easy to disperse in water
• has a low solution viscosity
• does not require a specific metal ion in order to form a gel.
Product Handling - Gelrite is packaged in 1, and 25kg drums with polyethylene liners. The drums should be kept closed and stored in a cool, dry place.
Gelrite powder is dispersed in cold water and the mixture heated to about 90°C. A suitable concentration of a salt is added, followed by the other ingredients. The mixture is poured or pumped into containers and allowed to cool undisturbed.
The concentration depends upon the type of metal salt. With divalent metal salts, such as calcium or magnesium, a lower concentration is required than with monovalent metal salts, such as potassium or sodium.
Gel Strength 400 - 700 g/cm 2; Transmittance not less than 80%; Particle Size at least 95% through 42 mesh (355 µm).
For perfect hygiene directly at the workplace, for ultra fast disinfection and sterilization a guaranteed quality product Biological investigations and tests prove that the constant 250°C (482°F) temperature maintained in the glass-bead container guarantees complete destruction of all microorganisms and spores within a few seconds. The one part of the instrument which is inserted into the STERI glass-beads is sterilized.
Nitrile glove is one of the highest quality brands available today. The quality exceeds industry standards (ASTM D 6319) by minimizing the number of critical defects (AQL 1.5). Nitrile glove is continuously tested for possible development of sensitivity to prevent skin irritation. Nurses and doctors use nitrile gloves in high-stress environments, high contamination areas, as well as when handling hazardous chemicals. Nitrile glove is preferred by many healthcare workers because of the extra protection. Most healthcare facilities use a combination of latex or vinyl exam gloves with nitrile exam gloves. In such cases, the latex or vinyl glove is used as the all-purpose medical glove.
HAEMACYTOMETER COUNTING CHAMBERS
Neubauer, Fuchs Rosenthal, Bright line, Cover-glasses
A specimen slide which is used to determine the concentration of cells in a liquid sample. It is frequently used to determine the concentration of blood cells (hence the name “hemo-”) but also the concentration of sperm cells in a sample. The cover glass, which is placed on the sample, does not simply float on the liquid, but is held in place at a specified height (usually 0.1mm). Additionally, a grid is etched into the glass of the hemocytometer. This grid, an arrangement of squares of different sizes, allows for an easy counting of cells. This way it is possible to determine the number of cells in a specified volume.

Dynagria is a formulated tablet product that contains only one active ingredient, the auxin Indole-3-Butyric Acid, also known as "IBA".
The inert ingredient IBA is universally utilised in the agriculture and horticulture sectors to induce the development of roots, to enhance the performance and quality of the crop.
Dynagria when diluted is directly applied on the cuttings or by spraying it on the stumps or sprouts, to promote the initiation of the formation of adventitious roots and re-establishing the radical system of the sugarcane plants. The radical neo-formation of the roots induces a greater development of the bio-mass of the sugar cane plants, enlarging its vigour and resistance to adverse conditions in the environment, resulting in the increase of the crop.
Packaging: (8 Tablets x 6)

Vapor Line Integrator is a physicochemical steam sterilization monitor which relies on the migration of a dark coloured chemical melt along a paper wick to signal sterilizing (green for pass) or non-sterilizing (red for fail) exposure conditions. The extent to which the chemical melt travels along the wick (length of run) is quite reproducible and depends on: 1) the presence of saturated steam, 2) the exposure temperature and 3) the time of exposure. These are the three critical variables of steam sterilization. Vapor Line Integrator will accurately monitor all variables and integrate the effects of each into a stable, easy-to-read, ark colour bar display. Vapor Line will literally PASS or FAIL the steam-processed load...no colour interpretation of the bar is required.
