MEMBRANE FILTERS
Excellent level of particle retention Large load carry capacity High permeability to air Non-hygroscopic and biologically inert Chemical resistance to most solvents and reagents. Very high temperature resistance They offer below mentioned advantages;
CM: cellulose mixed ester membrane Particularly suitable for aqueous solutions. They are hydrophilic. Thermally stable to 121°C. Ideal for gravimetric analysis and are often used for contamination tests. PTFE: polytetrafluoroethylene membranes Particularly suitable with aggressive media, as well as to concentrated acids and bases. They are hydrophobic, they can be used up to 145°C.
NC: nitrocellulose membranes They are easily wettable and suited for filtration of aqueous solutions. In dry atmosphere these membranes are thermally stable at 125°C and can be autoclaved at 121°C. PE: polyester membranes They are hydrophilic. Particularly suitable for fine titration, dust analysis, aerosol analysis and ultra-purification of solvents.
RC: regenerated cellulose membranes These membranes are resistant to most organic solvents. They are mostly used for filtration of solvent mixtures and ultra- purification and degassing of HPLC eluents. CA: cellulose acetate membranes They have a low protein binding capacity and they are suited for aqueous and alcoholic media. They are hydrophobic and can be used for hot gases up to 180°C.

SYRINGES - “glass” - “with luer-lock”
Manufactured from borosilicate glass. Featured with a stainless steel luer-lock system. Luer-lock grabs the needle or syringe filter stem and guarantees leak-proof delivery of the liquid even under high pressure. Luer-Barrel and the piston can be repeatedly autoclavable. Ergonomically designed for single-handed operation.
Smooth piston movement offers reduced sliding force.
