Buggy source:
@Override public void registerRenderers(){
  RENDER_ID=RenderingRegistry.getNextAvailableRenderId();
  MinechemFluidBlock.RENDER_ID=RenderingRegistry.getNextAvailableRenderId();
  MinecraftForgeClient.registerItemRenderer(MinechemItemsRegistration.element,new ElementItemRenderer());
  MinecraftForgeClient.registerItemRenderer(MinechemItemsRegistration.molecule,new MoleculeItemRenderer());
  MinecraftForgeClient.registerItemRenderer(Item.getItemFromBlock(MinechemBlocksGeneration.microscope),new MicroscopeItemRenderer());
  MinecraftForgeClient.registerItemRenderer(Item.getItemFromBlock(MinechemBlocksGeneration.decomposer),new DecomposerItemRenderer());
  MinecraftForgeClient.registerItemRenderer(Item.getItemFromBlock(MinechemBlocksGeneration.synthesis),new SynthesisItemRenderer());
  MinecraftForgeClient.registerItemRenderer(Item.getItemFromBlock(MinechemBlocksGeneration.blueprintProjector),new BlueprintProjectorItemRenderer());
  MinecraftForgeClient.registerItemRenderer(Item.getItemFromBlock(MinechemBlocksGeneration.leadChest),new LeadedChestItemRenderer());
  ClientRegistry.bindTileEntitySpecialRenderer(MicroscopeTileEntity.class,new MicroscopeTileEntityRenderer());
  ClientRegistry.bindTileEntitySpecialRenderer(DecomposerTileEntity.class,new DecomposerTileEntityRenderer());
  ClientRegistry.bindTileEntitySpecialRenderer(SynthesisTileEntity.class,new SynthesisTileEntityRenderer());
  ClientRegistry.bindTileEntitySpecialRenderer(BlueprintProjectorTileEntity.class,new BlueprintProjectorTileEntityRenderer());
  ClientRegistry.bindTileEntitySpecialRenderer(LeadedChestTileEntity.class,new LeadedChestTileEntityRenderer());
}

Fixed version (ground truth):
@Override public void registerRenderers(){
  RENDER_ID=RenderingRegistry.getNextAvailableRenderId();
  MinecraftForgeClient.registerItemRenderer(MinechemItemsRegistration.element,new ElementItemRenderer());
  MinecraftForgeClient.registerItemRenderer(MinechemItemsRegistration.molecule,new MoleculeItemRenderer());
  MinecraftForgeClient.registerItemRenderer(Item.getItemFromBlock(MinechemBlocksGeneration.microscope),new MicroscopeItemRenderer());
  MinecraftForgeClient.registerItemRenderer(Item.getItemFromBlock(MinechemBlocksGeneration.decomposer),new DecomposerItemRenderer());
  MinecraftForgeClient.registerItemRenderer(Item.getItemFromBlock(MinechemBlocksGeneration.synthesis),new SynthesisItemRenderer());
  MinecraftForgeClient.registerItemRenderer(Item.getItemFromBlock(MinechemBlocksGeneration.blueprintProjector),new BlueprintProjectorItemRenderer());
  MinecraftForgeClient.registerItemRenderer(Item.getItemFromBlock(MinechemBlocksGeneration.leadChest),new LeadedChestItemRenderer());
  ClientRegistry.bindTileEntitySpecialRenderer(MicroscopeTileEntity.class,new MicroscopeTileEntityRenderer());
  ClientRegistry.bindTileEntitySpecialRenderer(DecomposerTileEntity.class,new DecomposerTileEntityRenderer());
  ClientRegistry.bindTileEntitySpecialRenderer(SynthesisTileEntity.class,new SynthesisTileEntityRenderer());
  ClientRegistry.bindTileEntitySpecialRenderer(BlueprintProjectorTileEntity.class,new BlueprintProjectorTileEntityRenderer());
  ClientRegistry.bindTileEntitySpecialRenderer(LeadedChestTileEntity.class,new LeadedChestTileEntityRenderer());
