Synthetic materials – 8 types in acryl HG0112
Coal - sources and products of its processing (plexiglass) HG0122 This set presents main sources of coal and products of its processing. Small fragments of fossil coal embedded in the plexiglass, such as: lignite, hard coal, anthracite and samples of materials which can be formed by them during pyrolysis or chemical treatment processes (gas, carbon fiber, coke, ammonia, naphthalene, fertilizers, pesticides, drugs, dyes and which is often added in the production of rubber as an ingredient that reduces its hardness in the vulcanized state). • 18x3,5x2,5cm
Petroleum - distillation and products (plexiglass) HG0121 CRUDE OIL DISTILLATION AND ITS PRODUCTS. The set contains small samples of crude oil and its derivatives formed during distillation in CDU / VDU units (atmos- pheric and vacuum distillation). Inside the transparent plexiglass, it is possible to see the samples of crude oil and its derivatives. The diagrams connecting the sam- ples provide information not only about the distillation process which formed them, but also the relative vola- tility of the distillates. • 18x14x2,5cm
Set of 8 pieces of different materials embedded in acrylic blocks. The individual samples were placed in transpa- rent material in order to view the samples comfortably without fear of damaging them. The students can see up close the characteristic features of each material. There are 8 elements in the acrylic bar: ceramics, metal, glass, MDF, plastic, paper, cloth, cement. • 14 x 6 x 1,5 cm
Graphite model HG1040
Ice model (water) QH3331
Diamond crystal model HG1038
Sodium chloride model HG1031
This set helps to create a three-layer graphite model with 15 carbon atoms in each layer. The diameter of atomic parts varies from 14.5 - 15 mm. Thanks to the molecular graphite model, students can easily learn about the molecular structure. • The set includes: 45 carbon, black, dia. 23 mm; 51 grey bonds; 16 purple bonds.
Set presenting the molecular structure of ice. It contains molecular models of the ice structure which can be built with 78 atom parts. Thanks to this set, students can easily learn about the molecular structure of ice. The diameter of atomic parts varies from 14.5 - 15 mm. • The set includes: 26 x red oxygen atom; 52 x white hydrogen atom; 52 x white covalent bond; 40 x purple hydrogen
A three-dimensional model of the cha- racteristic crystal diamond structure. The molecular model ot the Diamond is an excellent teaching aid for chemistry.
This molecular model presents the structu- re structure of sodium chloride molecules. • The set contains the following models of the particles: 13 sodium atoms, grey, dia. 23 mm, 14 chlorine atoms, green, dia. 32 mm, 54 medium bonds
