Q: How do I use the 200 300 Mesh Domestic Copper Grid Common Micro Carbon?

A: The 200 300 Mesh Domestic Copper Grid Common Micro Carbon is ready to use right out of the box and makes an easy addition to your decor lineup.

Q: Why choose the 200 300 Mesh Domestic Copper Grid Common Micro Carbon?

A: The 200 300 Mesh Domestic Copper Grid Common Micro Carbon stands out in our decor range — have carried out in-depth discussion on this important subjectThrough the continuous improvement of process, a series of support membranes are launched to meet the needs of different usersUltra thin carbon support filmPorous membrane andFIBMicro grid is our exclusive product common problem A copper mesh usually used for transmission electron microscopyIt is the carrier net carrying the sampleThe carrier net is made of copperCopper meshIf it's nickelmolybdenumgoldnylonThe corresponding nickel meshMolybdenum meshGolden netNylon net, etc Copper mesh Separate use of carrier networkAlso called“Bare net”It is mainly used in biological sample preparationCan cooperate with slicerIn the sink“Bare net”Fishing for samplesThen conduct carbon spraying treatmentThen enter the electron microscope for observation Most TEM samples are preparedTo ensure that the sample can be carried in“Carrier network”upperWill be“Carrier network”Covered with an organic filmbe called“Supporting membrane”The carrier network with supporting membranebe called“Carrier support membrane”When the sample contacts the carrier support membraneIt will be firmly adsorbed on the support membraneIt will not slip from the hole of the loadFor observation under electron microscope Carbon supported membrane When the sample is placed in the mirror“Carrier support membrane”Will be irradiated by an electron beamCharge accumulation occurs on the organic support filmIt will also cause sample dischargeSample drift occursbeatRupture of supporting membrane, etcthereforeIt is considered to spray carbon on the support membraneImprove the conductivity of support filmGood observation effect is achievedThis process“Carbon sprayed mesh support membrane”abbreviation“Carbon supported membrane”The general film thickness is10-20nm From the production cost and use effectCopper mesh is more economical and practicalSo it is widely usedthereforePeople often mention“Copper mesh support film”“Carbon supported membrane”“Carbon film”“Fanghua membrane”etc.Even misnamed“Copper mesh”Mostly refers to this kind of“Supporting film of carbon spraying on copper mesh”Usually called“Carbon supported membrane” Micro grid support film To be exactMicro grid is a kind of support filmIt is used when making support membraneMicropores specially made on the membraneSo it's also called“Micro grid support film”It is also a carbon sprayed support membraneThe general film thickness is15-30nmIt is mainly to enable the sample to be carried on the edge of the micropore of the support membraneSo that the sample“No membrane”observationThe purpose of no film is to improve the image contrastthereforeObservation tubeRod shapeNano agglomerates, etcCommonly used“Micro grid”Supporting membraneGood effectEspecially when observing the high-resolution images of these samplesIt is a better choice The commonly used samples in the test are carbon support film and small hole micro gridIn fact, there is also an ultra-thin carbon film on the small hole micro gridHigh resolutionThe thickness of the sample is recommended to be controlled within20nmfollowingTherefore, the general diameter is less than20nmThe powder is fished directlyThe larger the particle is, the thinner the ion is after embedding Ultra thin carbon support film Ultra thin carbon filmIt is also a kind of support membraneIt is based on micro gridA thin carbon film is superimposedcommonly3-5nmThe purpose of this ultra-thin carbon filmA thin carbon film is used to block the poresSince the micro grid observation effect is goodWhy block the holeThis is mainly for those nano materials with good dispersionas10nmThe following samplesWell dispersed sample Porous carbon support membrane In our productsCarbon supported membranePure carbon filmMicro gate filmUltra thin carbon filmPorous membraneCoordinate network support film and so on are different productsI hope to distinguish them in useDetailed differencesPlease refer to relevant product data ◆High resolution observation of nanotubes with different lengthsWhich kind of membrane is better Looking at nanotubes generally has two purposesFirst, look at the lengthIt is mainly observed with low magnificationSecond, watch the wallMainly looking at high magnification images Whatever the lengthJust look at the high magnificationEspecially high resolutionMicro grid membrane or porous membrane is recommendedIt can meet the low observation lengthIt can also meet the requirements of high-resolution observationBut you must choose“High resolution transmission electron microscope”HRTEMotherwiseIt's hard for your micro grid to workunder normal conditionswell“Carbon supported membrane”High resolution images of carbon nanotube walls can also be seenBut it must not exceed the use“Micro gate film”Observed effect the reason being thatThere are holes in the micro gate filmThe tube wall can be observed at the hole of the micro gridThe carbon support membrane has no poresThe back of the film will affect the high-resolution observationThe same is true for powder samples ◆Observe what copper mesh is suitable for nano materials and biomaterials First purchase of carbon support membraneIt is often not known which mesh of copper mesh support film is suitableunder normal conditionsMaking nano materialsChoose300Objective or230Mesh copper mesh carbon support film is more suitableMaking biomaterialsSlice sampleChoose200Objective or150Mesh copper mesh carbon support film is more suitable If you make nano materials50nmfollowingAnd it depends on the high-resolution imageMicro gate film is recommendedIf you make nano materials10nmfollowingThe sample has good dispersionUltra thin carbon support film is recommendedBut the premise is to use high-resolution electron microscope200kVaboveIf using100kVElectron microscopeMicro gate film is not necessary
