A centrifuge is a piece of lab equipment that separates contents based on their densityWhen the machine spins it creates a strong centrifugal forceAs a result the separation process is accelerated and quick results are achievedTo Order 8801712355898 sales.
A faster filtration technique is vacuum filtrationHere a B252chner funnel is connected to a filter flask using a rubber adaptorThe filter flask looks like an Erlenmeyer flask but it has a side arm that connects the flask to the vacuum via vacuum tubingThen a flat piece of filter paper is placed inside of the funnel and wet slightly before the vacuum is slowly turned onThe liquid is sucked through the filter paper into the flask while the solid is retained on the filter paper.
A heating mantle can easily generate enough heat to vaporize most organic materials and will melt a flask if used on full powerAlways plug the heating mantle into a grounded variable voltage transformer or percentage timer control which runs at full power but cycles on and off to control the heatSuch devices are often known by the.
A heating mantle as the name suggests is a piece of equipment used in chemistry biology laboratories for heating and stirring operationsThe equipment precisely fits the boiling and distillation flask with a round bottom providing consistent and controllable heatingUsing a heating mantle is a relatively safe way for heating organic liquids.
A Variac is a fancy type of transformer it controls the amount of electricity flowing to an applianceThey are used in the organic chem teaching labs to control heating mantles never use a heating mantle without a Variac Variacs are quite heavyIf they are dropped on the floor or the lab bench they will break.
Aug 03 2021 Heating mantles are a relatively safe way to heat flammable organic liquids in a round bottomed flask Figure 1The mantles are cupshaped and designed for different sizes of round bottomed flask Figure 1If a mantle does not fit a round bottomed flask perfectly sand can be added to ensure good thermal contact Figure 1.
Autoclave or Steam Sterilizer is one kind of lab machine that is used in medical and laboratories for the sterilizing processSterilization is a process to disinfect any item or equipmentMicroorganisms such as bacteria and spores are killed by autoclave sterilization by using heatThe pressurized steam delivers the necessary heatTO KNOW PRICE OR ORDER 8801712355898 sales.
