Manufacturer: Chemplex Brand: Chemplex Model: 256

Microporous Film is a gas permeable membrane that enables the analysis of non-volatile liquid and powdered sample substances in helium flushes or vacuum. Pressure differentials within the sample cup and sample chamber are equalized while maintaining a taut thin-film sample support plane. The Series 1500 XRF Sample Cups are designed for use with Microporous Film. One of two supplied Snap-On Rings included with the 1500 Series Sample Cups is used to attach Microporous Film to the Cell neck of the open end of the sample cup nearest the outer integrated flange. The sample cup Cell is designed with the unique "bead-to-indent" geometry that creates taut thin-film sample support planes and effective seals against leakage. The second included Snap-On Ring is used to affix a thin-film sample support window to the opposite open end of the sample cup. In practice, the illustrated assembly procedure is reversed. The thin-film sample support is attached first enabling one or more sample cups to be conveniently filled from the top end; Microporous Film is attached last. Microporous Film is also available in Easy-to-Use Precut Circles for elimination of trimming and convenience of attachment to Chemplex XRF Sample Cups.

Manufacturer: Protea Biosciences, Inc. Brand: Protea Model: CMS-105-5

The Ultrapure 3-Hydroxypicolinic Acid (3-HPA) is a matrix for use in the analysis of oligonucleotides by matrix assisted laser desorption ionization (MALDI) mass spectrometry. The matrix is recrystallized for maximizing S/ N and minimizing salt adducts.

Manufacturer: Protea Biosciences, Inc. Brand: Protea Model: SP-302-kit

The SCX ProteaPrep 96 well plate is a polypropylene plate containing immobilized 5 um, 300 Ã…, SCX silica beads for clean-up of intact protein samples prepared for MALDI and electrospray mass spectrometry. Simple desalting and sample clean-up is accomplished using a vacuum based system, which allows for quick and simultaneous processing of 96 samples. The SCX ProteaPlate is supplied with the appropriate reagents for desalting which include a sample reconstitution buffer (25 mL), a sample wash buffer (2 x 25 mL) and an elution buffer (25 mL), as well as a sample collection plate. Each well can effectively bind up to 1 mg of protein and accommodate sample volumes of up to 300 uL in each well.

Manufacturer: Thomas Scientific Brand: Biotek Instruments Inc Model: 6880G99EA

The Biotek 660nm wavelength filter is intended for use with the ELx800 series of absorbance microplate readers (sold separately) for clinical biotechnological and pharmaceutical applications. It uses a tungsten halogen light source and fits into one of five slots in the reader's filter wheel. This 630nm filter is suitable for use in clinical and life science laboratories in applications such as enzyme-linked immunosorbent assay (ELISA) assays, protein and nucleic acid quantification, and enzyme-activity assays.BioTek manufactures microplate instruments and software used in biotechnological and pharmaceutical applications. The company, founded in 1968, is headquartered in Winooski, VT.
