NS-Glass stoppers, hollow borosilicate glass 3.3
Manufactured from borosilicate glass 3.3 which is resistant to heat and almost all chemicals. They meet the highest quality standards according to DIN 12252. Lower closed end of stopper features a "drip-tip" to ensure adhered liquid is returned to the flask. Hexagonal flat head prevents the stopper from rolling and allows stopper to be stood on end preventing contamination of the ground surface.
Nuclepore® membrane filter, PC
Hydrophilic, low protein bindingSmooth surface for easy identification of particlesHighly resistant to chemicals and good thermal stabilityAutoclavable up to 121 °CApplications: Ideal for environmental and water analysis.
Nunc EZ Flip 15 and 50 ml Conical Centrifuge Tubes
The integrated leakproof hinged-cap prevents cross-contamination and lost closures and enables one-handed opening and closing. Clarified polypropylene combines chemical resistance and high-speed tolerance. The tubes feature an ergonomic design, and are compatible with any fixed-angle or swing centrifuge rotor. With graduations and white writing area. The tubes are RNAse/DNAse free, USP Class VI, pyrogen-free, non-cytotoxic and leak-proof.

PF - laboratory-flange triple clamp, 18/10 stainless steel
Holder for all PF- laboratory flasks for the alternating removal of vessel and lid. This special quick-release fastener ensures that the two laboratory flat flanges of reaction tube and flat flange lid are connected and, in addition, that the reaction tube and flat flange lid are held individually (optimal flange angle 45°). Without accessories.
Phase separating papers Grade 480, circles
Filter discs are impregnated with silicon and are suitable for separating water and organic solvents. The aqueous phase is retained, but the solvent can flow through.
Phase separating papers Grade 480, folded filters
Filters are impregnated with silicon and are suitable for separating water and organic solvents. The aqueous phase is retained, but the solvent can flow through.
Phase separators, 1PS
A silicone impregnated, water repellent paper which can be used to separate aqueous solutions from immiscible solvents. The aqueous phase is retained and the organic phase passes through. Will retain solid particles. Can be used either flat under suction not exceeding 70mm Hg or quadrant folded in a conical glass funnel. Supplied in box of 100 circles.Note: This paper contains a small quantity of tin complex catalyst. It is therefore not recommended for use when this complex may cause interference, e.g. with the use of dithizone (diphenylthiocarbazone) reagent.
Phase separators, Grade 480, folded filters
Hydrophobic, silicone-impregnated filter paper. Allows the aqueous phase of an emulsion or other mixture to be separated based on water affinity. Suitable for the analysis of dressings or sauces.
