Homogenizer(Tissue Grinder, Glass Pestle)
Designed to handle both initial grinding and final homogenization in the same sequence of operations. The lower conical section is intended primarily for the initial grinding. To assist in this work the clearance between mortar and pestle can be adjusted at will by raising or lowering the pestle. The upper cylindrical section is for the final homogenization
Volatile Oil Apparatus (Clevenger) Apparatus for the Determination of Essential Oils in Vegetable Drugs.
The determination of essential oils in vegetable drugs is carried out by steam distillation in a special apparatus in the conditions described below. The distillate is collected in the graduated tube, using xylene to take up the essential oil; the aqueous phase is automatically returned to the distillation flask
Franz Diffusion Cell
Vertical glass diffusion cells are classic Franz Cells. Standard orifice diameters are 5mm, 7mm, 9mm, 11.28mm, 15mm, 20mm and 25mm, other diameters are custom. The word “orifice” as it refers to a Franz Cell is the area at the top of the receptor chamber that is exposed to the membrane or device through which transport or permeation is being studied. Corresponding volumes from 5ml to 20ml are standard and are listed under Typical Dimensions. Clamping is achieved through o-ring joints, flat ground (ground o-ring) joints and flat flange joints. We have our own clamps for the most popular Franz Cell models.
Hallimond Tube
Flotation is an important method for separating particles of different chemical and physical natures from pulverized minerals. Flotation depends basically on the formation of a gas, liquid, solid interface where the solid particle becomes attached to a gas bubble as a result of its hydrophobic surface characteristics
Percolator
(a narrow, cone shaped vessel open at both ends) is generally used
Percolation is continuous downward displacement of the solvent through the bed of the crude drug material to get extract
