PAGOW Buchner Funnel Flask Adapter Set, Filter Adapter Cones Set, Tapered Collar Green, Lab Buchner Funnels-Wear-Resisting Smooth Surface Pack of 9

Set of 9 different size neoprene adapter cones designed to fit Buchner and fritted glass funnels.
Made of Neoprene: These adapter cones are designed to fit around the stem of Buchner funnels, porcelain filters (minus headpieces), and fritted glass funnels. Extremely useful in the reverse flow cleaning of filter crucibles..
Widely Used:Perfect for supporting funnels, Gooch crucibles, filter tubes and other apparatus that are routinely used in filtration assemblies..
With different sizes of adaptersL: can be used individually or in a nested combination with one or more adjacent sizes..
Fully autoclavable:Fully functional even if they are not tightly fitted around the stem of the funnel being used. They are also an excellent alternative to boring special sized holes in rubber stoppers, or using the more unstable rubber filter aid..

Material: This crucible lifting and metal pouring tongs are made of high quality carbon steel that offers you durability and longevity..
Size: Crucible Lifting Tong measure 32 inch in total and can lifting crucibles from 1 kg to 10 kg and Adjustable Pouring Tong with 21-inch-long handle each side and adjustable diameter ring can securely hold 10 kg crucible..
Lift & Pour Design : Lifting tong is used to take out crucible full of molten metal from the furnace and then it is placed in pouring. This set of tongs provide better control while handling hot liquid metal. It requires two people pour the molten metal due to heavy weight of the crucible and tongs handle design..
Well Aligned Handles: The handles of the tongs are nicely fixed with rivet and properly aligned for better grip over the crucible and easy lifting and pouring..
Safety: These tongs with firm grip can hold crucible securely and allow user to be more convenient and confidence while moving a very hot crucible from place to place.

Specification: For 665g Gold / 320g Silver.
Selected Material: Graphite ingot molds are made from high density fine grain graphite, 99.95% Graphite. Ash content less than 0.1%. Better for Refining than Silicon Carbide Graphite Crucibles..
Well-made: The smooth cavity finish of the graphite ingot mold makes the ingot very easy to remove without sticking to the mold itself..
Wide Application: The graphite ingot mold receives liquid metal of precious metals and other types of metals, such as gold, silver, metal, aluminum, copper, brass, zinc and so on, and conserves them until they are solidified.
Extremely Durable: Great alkali resistance and corrosion, super acid and impact resistance..

Material: This crucible lifting and metal pouring tongs are made of high quality carbon steel that offers you durability and longevity..
Size: Crucible Lifting Tong measure 32 inch in total and can lifting crucibles from 1 kg to 10 kg and Pouring Tong with 14 inch long handle and 4.96 inch ring diameter can securely hold 4 kg crucible..

...hat the metal purity will not be affected during metal refining. The metal casting molds feature with nice thermal stability and suitable for rapid cold and hot working conditions. The durable graphite ingot molds have a long working life and can be used as more as 20,000 times. Better than Silicon Carbide Graphite Crucibles..
[INGOT MOLD SIZE] - Outer Dimension 3.93x1.97x0.98inch(100x50x25mm), inner dimensions 3.54x1.57x0.79inch (90x40x20mm). Volume 60ml. Capacity: 1000g Gold or 540g Silver..
[HIGHLIGHT FEATURES] - Completed with good thermal conductivity, the ingot molds can greatly shorten the melting time and save energy. The premium graphite ingot molds can withstand up to 3600°F (2000 ℃). Strong acid and alkali resistance, good corrosion resistance, impact resistance, 75MPA compression resistance, and 55MPa flex resistance..
[WIDE APPLICATION] - The metal casting molds can be applied for experiments and smelting of non-ferrous metals, such as gold, silver, copper, aluminum, lead and more. The ingot molds can also work as graphite crucible for melting into non-ferrous metals, test analysis, or other purposes..
[WARM TIPS] - Pure graphite crucible can NOT be heating by carbon furnace or charcoal kiln. If so, the metal casting molds will ....
