A new line of economical general purpose water baths that combine exceptional temperature control with full-featured digital functionality and ease of operation is now available. Designed to accommodate a wide variety of clinical and laboratory applications, these versatile water baths maintain bath temperatures from ambient +5° to 99.9°C with ±0.1° stability and ±0.2°C uniformity. They are available with 2, 5, 10, 20, or 28 litre single chamber reservoirs. In addition to precise temperature control, PolyScience water baths feature a digital temperature readout that displays both the actual bath temperature and set point temperature simultaneously, three user-defined temperature preset buttons for the quick selection of frequently used temperature set points, and an integrated timer. Bath temperature can be displayed in either °C or °F. For added operational convenience, all models include a steeply gabled tilting cover that accommodates glassware of varying heights and permits easy loading and removal of samples while allowing condensate to drain neatly back into the bath. Baths with a 10 litre or large reservoir are also equipped with a reservoir drain. All models come equipped with a diffuser tray and test tube holding rack or racks.

Resistant to extreme temperatures (-196ºC to 388ºC), chemicals & solvents, alcohol, humidity & moisture, CILS 8/9100 sample I.D labels are fully printable straight from a standard laser, inkjet or thermal transfer printer allowing variable data (batch no’s, barcodes, etc) to be added ‘in minutes’, saving time and eliminating the risk of smudged/illegible handwritten data. The specially formulated, high-tack adhesive also provides permanent long-term adhesion to all labware.

For the automated isolation of cells directly from whole blood or buffy coat, LIAISON Ixt/ Arrow CellSep Advanced can isolate up to 3 cell types per sample in just 32 minutes per cell type, offering significant time savings compared to manual cell separation methods. Based on proven magnetic bead technology, CellSep Advanced is designed for use on the LIAISON Ixt/ Arrow instrument for the separation of 1, 2 or 3 cell types in up to 12 samples at a time. Requiring minimal hands-on intervention, the system produces good yields of purified cell preparations ready for use in a wide range of downstream applications, including lineage-specific chimerism analysis. The Ixt/Arrow automated platform also minimizes human error and ensures reproducibility between runs for consistent and reliable downstream analysis. Trials have shown that the performance of CellSep Advanced is equivalent to manual cell separation methods, in terms of cell quality and quantity. The product is part of a growing range of cell separation and nucleic acid extraction kits available for use on the LIAISON Ixt/ Arrow instrument, meeting the demands of modern cell analysis applications and ensuring that reliable results are reaching clinicians at the earliest opportunity.

The traditional method of diagnosing vitamin B12 deficiency has been to measure the concentration of total vitamin B12 in serum. The total vitamin B12 concentration essentially reflects vitamin B12 which is bound to its two carrier proteins, forming holohaptocorrin (holoHC) and holotranscobalamin (holoTC). Whilst holoHC accounts for 70 % – 80 % of the vitamin B12 in serum, only holoTC (active vitamin B12) can be used by human cells. Measurement of total vitamin B12 can therefore give erroneous results because it measures the circulating vitamin B12 but does not reflect the level of active vitamin B12.  The Biohit Active B12 (Holotranscobalamin) ELISA test directly measures holoTC – the biochemically active form of vitamin B12 – in human serum. This test is well suited for the screening of patients with suspected vitamin B12 deficiency. It can also be used for confirming vitamin B12 status in the large number of patients receiving an inconclusive total vitamin B12 test result.
