These crimp/snap top low volume sample vials can be used with 6, 7 and 8 mm autosampler trays. They are made of borosilicate glass, type 1, class A.

Supplier: TOSOH BIOSCIENCE

TSKgel FcR-IIIA-5PW is a semi-preparative affinity column which immobilises the recombinant FcγRIIIA ligand bonded to pourous 10 µm polymethacrylate particles which can load up to 5 mg of mAb.

Supplier: Merck

Available with optimised 2 μm particulate silica, these UHPLC columns, based on Purospher® STAR RP-18 endcapped, are ideal for ultra-fast applications, where resolution, sensitivity and sample throughput are crucial. They are the first choice for high throughput screening and QC analyses, process monitoring, method development and LC-MS applications. Due to its balanced selectivity, Purospher® STAR RP-18 endcapped UHPLC columns cover almost all demanding separations with tailing-free chromatograms. Purospher® STAR RP-18 endcapped 3 μm columns are recommended for difficult samples where clogging and back pressure present an issue.

Supplier: Cytiva

Source 15S 4.6/100 PE is a strong cation exchanger prepacked in a Tricorn column for intermediate lab-scale purification and large-scale polishing of biomolecules with ion exchange chromatography.

Supplier: Thermo Fisher Scientific

Achieve superior reversed phase (RP) oligonucleotide separatons using the DNAPac™ RP HPLC columns. The unique chemistry is designed for analysis of oligonucleotides and double-sranded (DS) DNA/RNA fragments using LC-UV or LC-MS. The column chemistry provides excellent performance under a broaed range of pH, temperature and mobile phase composits.

Supplier: Thermo Fisher Scientific

Protein desalting spin columns are designed to desalt or exchange buffer of protein samples with volumes of 30 to 120 µl. These devices have exceptional desalting characteristics with ≥95% retention of salts and small molecules while providing excellent recovery of proteins greater than 7 kDa. Multiple samples can be processed in less than five minutes without cumbersome column preparation steps.

Supplier: HAMILTON BONADUZ

PRP-h5 polimeric reversed phase columns are ideal for applications that require a high degree of column-to-column and batch to batch consistency (quality assurance, clinical trials). Unlike C8 or C18 columns, PRP-h5 has no stationary phase coating. The integral reversed phase characteristics of the PRP-h5 column eliminate the need for special coating techniques. Since there is no stationary phase to hydrolyse, the column maintains its performance characteristics longer than many C8 or C18 columns. PRP-h5 columns are packed with a poly(styrene-divinylbenzene) material.

Supplier: CHIRAL TECHNOLOGIES

CHIRALPAK® QN-AX and CHIRALPAK® QD-AX are enantioselective weak anion-exchange (AX) HPLC columns. The chiral selectors for CHIRALPAK® QD-AX and CHIRALPAK® QN-AX anion exchange phases are based on complementary quinine (QN) and quinidine (QD) derivative selectors bonded to high efficiency 5 µm diameter spherical silica. The structure of these selectors is such that a tertiary amine is located in a three-dimensional cleft surrounded by additional hydrogen binding sites and a large aromatic group. This combination provides excellent separations of chiral acids.
