3 Way Distilling Adapter Vigreux with 10/18 Top Thermometer Joint & 24/40 Lower Joints
The 3 way distilling thermometer adapter is similar to HMA016103 but with vigreux in the column near the lower male joint. and has a 10/18 thermometer joint at top. With two 24/40 inner joints at bottom and side, and the two joints are at a angle of 75 Degree. These frosted, precision-grounded provide a leak free way to connect the distilling column or distilling flask with glass condenser in the simple distillation, fractional distillation, vacuum distillation.
Laboy Glass 3 Way Distilling Thermometer Adapter with 24/40 Joints
The 3 way distilling thermometer adapter has a compression cap to form a vacuum tight seal of plain thermometer on Top. With 24/40 two inner joints at bottom and side, and the two joints are at a angle of 75 Degree . The bottom joint is usually connected to a distilling column for fractionation distillation or a distilling flask for the steam or vacuum distillation. The side joint may connect to a liebig or west condenser for water in and out when the temperature below 150 degree C, connect a air condenser if temperature above 150 degree C. The compression cap and o-ring fitting the thread opening at the top of the adapter, accommodating a thermometer or bleeding tube.
Cow-Type Distilling Receiver Apparatus Distribution Adapter with 24/40 Joints & Hose Connection
With 24/40 top female joint to fit a distillation head,and three 24/40 male joints at lower connects three round bottom flasks with 24/40 female joints. With a 10mm serrated glass connection attached to a vacuum or inert gas source.
Short Path Distillation Head with Vigreux Vacuum Distillation Apparatus with 24/40 Lower Inner Joints & 10/18 Thermometer Joint
Short path distillation is a compact purification method of vacuum distillation involving the vapor from the heating flask (a round bottom flask with standard joint)travelling a short distance, often only a few centimeters into the tubing before being condensed.A short path ensures that little compound is lost on the sides of the apparatus.Because it uses a lower boiling temperature, short-path distillation equipment has advantage for separating compounds that are unstable at higher temperatures. It’s also beneficial for purifying small quantities of compound.
Short Path Distillation Head Vacuum Distillation Apparatus Vigreux with Jacked Coiled Condenser with 24/40 Lower Inner Joints
Short path distillation is a compact purification method of vacuum distillation involving the vapor from the heating flask (a round bottom flask with standard joint)travelling a short distance, often only a few centimeters into the tubing before being condensed.A short path ensures that little compound is lost on the sides of the apparatus.Because it uses a lower boiling temperature, it has advantage for separating compounds that are unstable at higher temperatures. It’s also beneficial for purifying small quantities of compound. The short path distillation head is a key component in a short path distillation apparatus,a distillation head with condenser is designed with a very short path with thermometer joint for vapor passing from the heating flask to a connected condenser part.
