We have developed a unique portfolio of consumables, each adapted to the different feed water quality requirements and to your various applications. To maintain your water system’s performance, it’s critical to replace your purification cartridges on time and with genuine ISO 9001-certified parts.
Strat-M® Membrane for Transdermal Diffusion TestingExperience the unmatched predictability of Strat-M membrane – a synthetic, non-animal based model for transdermal diffusion testing that is predictive of diffusion in human skin without lot-to-lot variability, safety and storage limitations.Strat-M membrane is designed for screening of:•Active pharmaceutical ingredients (API) •Cosmetic actives •Formulations •Personal care products •Pesticides and chemicals Human Skin CorrelationStrat-M membrane is predictive of diffusion in human skin for a wide range of compounds and formulations. Use the Compound Correlation Tool to learn how well Strat-M membrane will work for you.Reproducible Diffusion Data:No need to repeat testing each time a new lot of skin arrives in the lab. Strat-M membrane is a highly consistent, engineered material that allows you to compare today’s diffusion data with data you will generate next week, or next month. Furthermore, lot-to-lot consistency brings a new level of clarity to your test data, simplifying your analysis.Sensitive to EnhancersStrat-M membrane exhibits differential permeability in the presence of enhancers and is compatible with common formulation formats, so it is appropriate for use during formulation optimization.Ultimate Experimental ConvenienceStrat-M membrane was designed with convenience in mind. The Strat-M membrane is shelf-stable and stocked in the warehouse so procurement and storage is a breeze. Each membrane is individually packaged as precut discs and do not need to be hydrated prior to use. Simply remove the Strat-M membrane disc from its pouch and load into a Franz cell.

Incubate total and fecal coliforms, fecal streptococci and other microorganisms- Complies with Standard Methods requirements - View samples through clear plastic inner door without opening, preventing temperature fluctuations - Compact lightweight portable unit for field use
Simply and efficiently concentrate and desalt solutions of any macromolecule, using any centrifuge that can accept 1.5 mL tubes. With the low-binding Ultracel® membrane, Microcon® filters offer:•Typical recoveries of greater than 95%, even for dilute solutions •Reverse spin to maximize recovery, even in the smallest samples •Convenient storage of filtrate or concentrated sample in standard microfuge tube •Concentration factors up to 100X Microcon® DNA Fast Flow FilterOptimized for the concentration and recovery of genomic DNA with SDS buffer. The low nonspecific binding characteristics of the membrane and the other device components, coupled with its medical-grade o-ring seal, allows the device to accommodate several wash steps with minimal sample loss.Features:•High recovery for small volumes with reverse spin (concentration factor less than 20X) •Low-binding Ultracel® membrane •Fast processing Sample applications:•Recovery of genomic DNA for forensic applications •Concentration and desalting of nucleic acids (high recovery alternative to ethanol precipitation) •Removal of primers from amplified DNA •Easy filtrate recovery, exploiting the flat membrane design
