Sigma Aldrich Fine Chemicals Biosciences Sera MagTM Magnetic Olidod
Sera-Mag(TM) SpeedBeads(TM) and Sera-Mag(TM) Carboxylate-Modified Magnetic Particles combine a fast magnetic response time and high binding capacity with a large surface area high sensitivity stability physical integrity and fast reaction kinetics. Covalent coupling of biomolecules such as proteins and nucleic acids to carboxyl groups on the surface is easily accomplished using our standard coupling technology. The core of the particle is made by a free radical emulsion polymerization of styrene and acid monomer. One (Sera-Mag(TM)) or two (Sera-Mag(TM) SpeedBeads(TM)) layers of magnetite are then coated onto this core while the surface is modified to minimize non-specific binding of proteins.
Sigma Aldrich Fine Chemicals Biosciences HiLoadR 16/600 SuperdexR 2
HiLoad(R) 16/600 Superdex(R) 200 prep grade are prepacked XK columns designed for high-resolution preparative gel filtration chromatography. The column is an excellent choice for separating MAbs from dimers and contaminants.Superdex(R) prep grade (pg) is produced by covalent bonding of dextran to highly cross-linked agarose.The separation properties of these media are determined by the dextran component. Steep selectivity curves give excellent resolving power for peptides and proteins in the molecular weight ranges Mr < 10 000 (Superdex(R) 30 pg) Mr 3 000 to 70 000 (Superdex(R) 75 pg) and Mr 10 000 600 000 (Superdex(R) 200 pg). The medium combines high mechanical strength with high hydrophilicity allowing high flow rates and minimal nonspecific interactions.
Sigma Aldrich Fine Chemicals Biosciences DuranR double walled jacke1EA
The DURAN double walled wide mouth bottles GLSA80 incorporate an integral jacket that isolates the contents from the external environment. Heated or cooled liquids can be circulated through the jacket to control the temperature within the screw topped DURAN bottle. The DURAN double walled bottles offer a sealable and more flexible alternative to open topped jacketed beakers.
Sigma Aldrich Fine Chemicals Biosciences BenchRockerTM variable 2D1EA
The BenchRocker 2D is designed to provide the precise speeds and tilt angles required for a broad range of molecular and biological mixing applications. The user can adjust both parameters to match the vessel size and the volume of liquid being mixed yielding optimum results.
Sigma Aldrich Fine Chemicals Biosciences PyrexR large top desiccato1EA
These 10.5L PYREX desiccators have rugged 24/29 Standard Taper external sleeves with tooled hose connections that serves as the stopcock. They are designed so that its manipulation is not affected by the vacuum. The open position is indicated by the molded arrow on the cap. A quarter turn from this position closes the desiccator. For ease in use and improved performance it is recommended that the Standard Taper sleeve be lubricated with a silicone-based vacuum grease. The tubulation O.D. is approximately 10mm. Bowl capacity is 10 500mL. Warning Do not heat or subject to pressure. Rated 1- atmosphere vacuum.
