For the experiments of extracting compounds from solid substances in the laboratory, a Soxhlet extractor (as shown in Fig) is generally used. Soxhlet extractor is composed of three parts: extraction bottle, extraction tube and condenser, with siphon and connection tube on both sides of the extraction tube. Using the principle of solvent reflux and siphon, the solid material is continuously extracted by pure solvent, which saves the solvent and has high extraction efficiency.Suitable for scientific research, colleges and universities, medicine and health care, and industrial and mining enterprises and other units of the laboratory.

Microlab Scientific has introduced , a new turnkey filtration manifold system that can be combined with several different funnel options. Developed for flexibility and ease-of-use, MVF features a modular design and field - tested accessories that make it a more convenient and economical alternative than its conventional, single-funnel counterparts.

Vacuum Filter is used primarily in microbiological and analytical procedures that involve collecting a particulate (bacteria, precipitate, etc.) from a liquid suspension. Liquid poured into a funnel passes through a filter, which retains the particulate, and filtrate can be collected into a filter flask, directly or via a vacuum manifold. Applying vacuum reduces process time compared to gravity flow.

Microlab Glass Fiber Filters are import from a famous Germany manufactuer. And the Glass fiber is made of 100% borosilicate glass that is binder free. These depth filters combine fast flow rate with high dirt loading capacity and retention of fine particulates. The small fibers diameters of glass media provide superior efficiency and dirt holding as compared to cellulose and other synthetic media.

Microlab®  Cellulose Acetate (CA) Filtration Membrane is unsupported, hydrophilic membrane .Composed of pure cellulose acetate, the membrane has dimensional stability and naturally low protein binding. This provides higher throughput than competitor offerings and reduces the amount of filter changes needed during filtration of proteinaceous solutions. It is ideal for use in filtration applications where maximal recovery of protein is critical. In addition,CA membrane combines good chemical resistance ranging from PH4-8, high flow rates and thermal stability, therefore is ideally suitable for pressure filtration devices, like syringe filters, disposable vacuum filter funnels etc.

Microlab®Regenerated cellulose (RC) membrane is made of pure cellulose without adding any wetting agents and reinforced with nonwoven material. RC membrane is a very clean membrane features low extractables and ultra-ow non-specific binding characteristics. Naturally hydrophilic property and wide compatibility makes RC filter suitable for both organic and aqueous media applied in chromatography sample preparation and solvent preparation.In addition,the high-quality microporous structure helps to decrease impact on sample analysis at a minimally level.RC membrane have very low protein binding capability,which is also very good for tissue culture filtration and universal biological sample filtration.

Microlab® polypropylene (PP) microfiber filters is constructed of pure polypropylene microfiber, which belongs to a membrane filter material for depth filtration.Polypropylene membrane is natural hydrophobic, can withstand a variety of organic solvents, has excellent chemical stability and chemical compatibility Polypropylene membrane is tough and durable, not easy to break, non-toxic, and with uniform strength, widely used in lots of industries. 

Microlab®Polyvinylidene Fluoride(PVDF) membrane is a kind of universal film, which is available in Hydrophobic or Hydrophilic Vision( hydrophilic treated), unsupported and PET supported vision to accommodate more industries. 

Hydrophobic PVDF membrane with excellent hydrophobic ability,fast air flow rate and professional general sterile filtration capability,easy for assembling as unnecessary to distinguish the front and back side,can be ideally used as a PVDF venting membrane filter or air filtration/sterilization for medical devices or diagnosis assay.

Hydrophilic PVDF membrane with very low protein binding and high flow rate features, is ideal for clarification, pre-filtration and sterile filtration of fluids such as water, diagnostic reagent, buffer, cell culture medium, ophthalmic solution, blood products/serum,etc, offering efficient bacterial and particulate retention.

Supported PVDF Membrane (PET support layer) with better mechanical strength than Unsupported PVDF membrane. Our PVDF Membrane is widely used because of its outstanding properties including high thermal stability excellent mechanical strength, chemical resistance, which makes it has good resistance to organic solvents, corrosion, oxidation and withstand solutions of pH 2-10.

Microlab® PTFE membrane is manufactured in a unique way where polytetrafluoroethylene (PTFE) is expanded both uniaxially and biaxially. It’s supported by a polypropylene net laminated to the underside to improve handling characteristics. Both hydrophobic and hydrophilic PTFE Membranes are available. 

Hydrophobic PTFE Membrane has good hydrophobility, excellent chemical resistance,
high porosity, excellent air permeability. The membrane is widely used for Air Monitoring and clarifying acids, bases, and solvents, propellants, analyzing hydraulic fluids, isolating RNA and so on.

Hydrophilic PTFE membrane is treated base on Hydrophobic PTFE membrane. It’s design as a Universal membrane for filtering both aqueous solutions and aggressive solvents, even mixture. 

Microlab® mixed cellulose ester (MCE) membrane filters are composed of cellulose acetate and cellulose nitrate. lt's one of the most widely used membranes in analytical and research applications. MCE membrane filter is characterized by smoother and more uniform surface than pure nitrocellulose（NC）Membrane filter. Also, the color contrast provided by the filter surface 
facilitates particle detection and minimizes eye fatigue. Microlab® also supplies sterile gridded Membrane Filters with or without adsorbent pads.
