Non-316 electric motor is wash down duty model that is highly resistant to corrosion and wet processing conditions. Homogenizer is used to draw in and wet out powdered solids such as mineral supplements, and difficult to disperse stabilizer such as xanthan gum. After incorporation of the solid powders, the homogenizer is reversed to provide a high velocity recirculating flow through the high shear rotor/stator mixing head. This provides extremely fine particle size distributions and complete mixing of each individual dosage. ARDE Barinco, Inc., 500 Walnut St., Norwood, NJ 07648.

Black Seal Syringes for syringe pumps

Two new syringes, 1.0 ml and 5.0 ml, for the XP 3000 Modular Digital Syringe Pump, have black seals to ensure a longer life. Seals are made of ultra high molecular weight polyethylene, rather than traditional Teflon. This harder material makes it an excellent choice for saline or other solutions that can crystallize and damage syringe seals.

Autosampler Vials easy to use

StepVial System provides an easy to use, reliable and cost effective sample vial for use with autosamplers. System is comprised of a sample vial and a limited volume insert with a choice of either a Poly Crimp Seal, Snap Top Cap, aluminum seal or a threaded closure. System design allows for the insert to be precisely positioned in the center of the vial neck, which eliminates any possibility of the autosampler needle jamming accidentally between the insert opening and the neck of the vial. An enlarged diameter neck opening on both the vial and insert provides a larger target area for the autosampler and facilitates manual pipetting. J.G. Finnean Associates, 3600 Reilly Court, Vineland, NJ 08360.

Window Creator for CE columns

The Window Maker is specially designed for controlled stripping of polyamide to create detection windows in protectively clad, fused silica capillaries. It creates a reproducible 2 mm window area on both coated and uncoated capillaries, but is not recommended for use with polyacrylamide or CE-100SA, sulfonic acid coated capillaries. By creating only a 2 mm window, column maintains its strength while providing an adequate area for detector line-up. Unit uses a program switch so that a controlled, reproducible window is created from capillary to capillary, analysis to analysis.
