96-well filter plate designed and optimized for aqueous solubility assaysDetermining a compound's aqueous solubility has become an essential early measurement to make in the drug discovery process. Poor water solubility can cause problems in many different in vitro testing techniques leading to unreliable results and/or reproducibility problems; insoluble precipitates have been shown to cause false positives in bioassays poten…

Incubate microorganisms, perform albumin tests, paraffin embedding and filter clearing.

Fluorescein sodium salt has been used as a solute to study microvessel permeability. It has been used as a test molecule to study blood barrier penetration. Water soluble fluorescent dye used in permeability and vascular perfusion studies due to its small molecular radius. Sodium fluorescein is used as a fluorescent tracer to study blood-brain barrier (BBB) and blood-spinal cord barrier (BSCB) permeability in rodent mode…

LiChrosolv hypergrade is accurately tested for LC-MS suitability, and meet all the requirements of modern LC-MS ionization methods (ESI/APCI - positive and negative mode). Thanks to their low level of ionic background and low ion suppression, LiChrosolv hypergrade solvents provide high reproducibility and high ionization efficiency. The packaging material has been improved to meet LC-MS quality requirements perfectly.

Steripak-GP filter units are designed for larger scale pressure-driven filtration of tissue culture media with or without serum. They are single use and are not autoclavable. The filter units come in two sizes, with the smaller unit able to filter up to 10 L and the larger up to 20 L. Both sizes utilize the low protein binding, fast flow 0.22 µm EMD Millipore Express membrane. Each unit has an integral filling bell for bottle-…

Steritop bottle top filter units provide a large filter area for rapid sterile filtration of aqueous fluids into narrow-mouth (33 mm) or wide-mouth (45 mm) bottles. A small tab inside the funnel secures an optional prefilter in-place during filtration. For added protection against contamination, the threads for bottle attachment have been slightly recessed in case the funnel accidentally touches a work surface

A 33 mm diameter sterile syringe filter with a 0.1 µm pore size hydrophilic PVDF membrane. Sold in packs of 50.

Ideal for sterilizing gases, venting sterile containers, and sterilizing or clarifying organic solutions.
