Sigma Aldrich Fine Chemicals Biosciences PercollR PLUS Cytiva 17 54
Percoll(R) PLUS is a silica-based colloidal medium for cell separation by density gradient centrifugation. The silica particles of the medium are covalently coated with silane providing product stability and long shelf life. The silane coating also provides low osmolality and toxicity as well as low viscosity. Percoll PLUS is aseptically filled and has low levels of endotoxins making it well-suited for cell separation in clinical research applications. Cell separation with the medium is performed under gentle conditions facilitating the isolation of a variety of cells subcellular particles and viruses where preservation of viability and morphological integrity is important. The low toxicity of Percoll PLUS ensures that removal of the medium from separated cellular particles is not usually necessary. After adjustment Percoll PLUS forms iso-osmotic gradients within the density range of 1.0 to 1.3 g/ml. This density range is especially useful since most cells subcellular particles
Sigma Aldrich Fine Chemicals Biosciences NorellR Standard SeriesTM
The Norell Standard Series NMR tubes are redesigned to eliminate tube wall and bottom variations. This improves shimming times and sample reproducibility.Manufactured out of ASTM Type 1 Class B glass or commonly referred to as N-51A these NMR tubes are designed for auto-sampling systems and high-throughput NMR spectroscopy.

Sigma Aldrich Fine Chemicals Biosciences PolypepR Low Viscosity his100G
A proprietary protein digest that provides increased stablization of tissue sections in histochemical studies.
Sigma Aldrich Fine Chemicals Biosciences Spurr Low Viscosity Embedd
Spurr resin is a hydrophobic resin. It is less viscous than epon mixtures and is easier to dispense. The low viscosity of the resin contributes to its penetration in tissue mineral and dense structures. A low viscosity of 60 cps also allows easy penetration into a variety of difficult materials.
Waters Corp Waters Syringe Valve, 4-Port, for 2707 Autosampler
This replacement syringe valve is designed for the 2707 autosampler. It functions as a 4-port selection valve, directing liquids for various functions including waste, wash, and connecting to the buffer tubing.
- Replacement valve for the 2707 autosampler.
- Features a 4-port selection design, with one port unused.
- Includes a dedicated “waste” port for draining the syringe dispenser.
- Equipped with a “wash” port for aspirating wash liquid from a wash bottle.
- Connects to buffer tubing via the “needle” port.
- Suitable for HPLC systems.
