View of Stone
The processed finished decorative stone can be identified from the following four aspects:
One view: Visually observe the surface structure of the stone.
In general, the uniform fine-grained structure stone has a delicate texture and is a stone product; coarse-grained and unequal-grained stone has poor appearance, mechanical mechanical properties are not uniform, and the quality is somewhat poor. In addition, due to the geological effects of natural stone, often produce some fine pulsation, micro-cracks in it, the stone is most likely to break along these parts, should be removed. As for missing edges and corners, it is even more aesthetically pleasing, especially when choosing.
The second volume: the size of the stone.
So as not to affect the splicing, or cause the spliced ​​pattern, pattern, line deformation, affecting the decorative effect.
Listening: Listen to the sound of the stone.
In general, the stone with good quality, internal compactness and no microscopic cracks, is crisp and pleasing to the eye; on the contrary, if there are microscopic cracks or fine veins inside the stone or the particles become loose due to weathering, knocking occurs. The sound is rough.
Four tests: Use simple test methods to check the quality of the stone.
Usually, a small drop of ink is dripped on the back of the stone. If the ink quickly spreads out and leaches out, it means that the internal particles of the stone are loose or there are microscopic cracks. The quality of the stone is not good. On the contrary, if the ink drops do not move in the original position, it means that The stone is dense and has a good texture. In the selection of finished plates, because stone materials are natural, it is not possible to have the same texture, and there are differences in the level of processing in mining and processing. Most stone grades are divided, and many dealers are also based on quality. However, there are also a few indiscriminate, shoddy and fraudulent consumers. In order not to make mistakes, the average consumer in the decoration of the best stone is not included in the contract, personally to the building city to buy.

4 Channel Reagent Reservoirs,8 Channel Reagent Reservoirs,12 Channel Reagent Reservoirs,96 Well Reservoir,384 Well Reservoir, from Yongyue Medical, is made of strong clear polypropylene (PP). Low profile designation which is suitable for small volume robotic tips used in high flux instruments. In the automatic pipetting process, the reservoir can perfectly overcome the surface tension of the liquid and minimize residual liquid
Our Reservoir Plates are perfect for storing volumes of samples to be pipetted into other microplates for further applications.
These plates are manufactured in cleanroom facilities which are certified free of RNase, DNase, human genomic DNA and endotoxins. We use only the highest medical grade virgin polypropylene with high resistance against chemicals such as DMSO, phenol, and chloroform. Pyramid channel bases are best for small volume recovery. The standard SBS footprint ensures its compatibility with automation.
Our sturdy and reusable reagent reservoirs can stand-up to autoclaving, exposure to temperature extremes, and chemicals. Made from polypropylene these reservoirs offer a stable base that makes them suitable for manual procedures as-well-as automation.
These fully automation compatible reservoirs feature an SBS footprint and can be used in plate handlers or stackers. To minimize space on platforms (when a stacker is not in use) or under hoods, these reservoirs can be filled and stacked.
Conical Bottom Design To Save Expensive Reagents
DNase/RNase & Pyrogen Free
Stable at -80℃
Conformed to ANSI/SBS Standards
