Sterivex filter units work with syringes, peristaltic pumps or pressure vessels. They eliminate the risk of contamination associated with decanting or pipetting.Sterivex units are designed to dispense into virtually any storage container. The devices are available with different outlet connectionsSterivex filter units can process volumes up to 1,000 mL or 2,000 mL, depending on the type of membrane used in the device. A choice…

The Steriflip filter unit is designed to work with standard 50 mL centrifuge tubes, which eliminates sample transfer. To filter, just attach the unit to a 50 mL centrifuge tube containing your sample, flip it over, and apply the vacuum. When finished, the filtrate collects in the attached 50 mL centrifuge tube.Steriflip Nylon Net filters are now available in 40, 60 and 100 µm pore sizes, making them ideal for stem cell, cardio…

The Stericap ™ PLUS Universal Bottle-Top Filter Device provides fast, large-volume filtration into any sized bottle.

Certified reference material, Trace CERT ® , 100 μg/mL each component in methanol, ampule of 1 mL.

HX0299 Hexanes, 98.5% ACS, ~64% n-Hexane

The Fused-Core ® particle technology behind Ascentis ® Express columns delivers maximum speed and efficiency on both HPLC and UHPLC systems. The novel superficially porous silica particles (SPP) are available in three different particle sizes and two different pore sizes for optimal suitability from micro over UHPLC and HPLC to semi-preparative use.

Monolithic silica-based Chromolith® HPLC columns allow rapid separations at very low column backpressure with high matrix tolerance and extended column lifetime, thus making them ideal products for high throughput and cost-efficient analyses of matrix-rich samples. 

With Millicell inserts, attachment or suspension cells can access media from both their apical and basolateral sides. Cell growth, structure, and function more closely mimic what occurs in vivo. In addition, Millicell inserts make it possible to study both sides of the cell monolayer.Millicell inserts are available for 24-, 12-, or 6-well plates. The inserts are easily prepared for SEM and TEM visualizing techniques, and they…

Five different pore sizes from 0.1 to 5.0 µmPre-sterilized units also availableFast filtration and highly reproducible performanceUse in fixed-angle rotors for 1.5 mL tubes

• High recovery Ultracel regenerated cellulose membrane in a range of molecular weight cut-offs• High retentate recovery of >90%• Vertical membrane reduces concentration polarization for ultra-fast spin times (as fast as 10–15 minutes)• Heat-sealed membrane minimizes downstream extractables• 100% integrity tested for reliable performance• Convenient sample monitoring with translucent housing and volume gradations• Direct pipet…

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…

Also known as androstanolone or DHT, 5α-Dihydrotestosterone is an androgen or male sex hormone that has been implicated in a broad range of disease from male pattern baldness to benign prostatic hyperplasia and prostate cancer. As an anabolic steroid, DHT has also been used as a performance-enhancing drug to promote muscle growth. This Certified Spiking Solution® is suitable for GC/MS and LC/MS applications from clinical and d…
