These 500 mL PYREX® Kuderna Danish Concentrators are supplied with Keck clamps instead of spring hooks. The complete apparatus consists of a 3-Ball Snyder column (with 24/40 Standard Taper joints), a 500 mL flask (with 24/40 Standard Taper top and 19/22 Standard Taper lower joint), and a graduated 10 mL tube with an outer 19/22 Standard Taper joint. The tube graduations go from 0 to 2 mL in 0.1 mL increments and from 3 mL on i…

This PYREX® general purpose condenser can be used for either distillation or extraction. Although the condensing area per unit length of the 200mm long jacket is low, the large capacity water jacket gives efficient cooling. Condenser tubulations are approximately 10mm O.D. The adapter end is tooled for uniform stopper fit, accommodating a No. 3 rubber stopper.

Translucent polypropylene graduated cylinders are manufactured with raised graduations at the primary scale points. Cylinders have a hexagonal base and are calibrated “to contain” (TC). Tolerances according to ISO 6706. Exposure to temperatures above 60°C may affect accuracy.

These 500 mL PYREX® flat bottom boiling flasks have full length outer 24/40 Standard Taper joints on long necks. They are manufactured from No. 7740 borosilicate glass. Wall thicknesses are carefully controlled to provide the proper balance between thermal expansion and mechanical strength for greater shock resistance. Their excellent chemical durability results in contamination-free results and long life under the toughest la…

Translucent polypropylene flasks are manufactured with blue graduations for reference. The flasks have a screw neck and are supplied with a polypropylene cap.

These 500 mL PYREX® wide mouth Erlenmeyer flasks are especially recommended for use as titration flasks and are designed with heavy duty rims to reduce chipping. For convenience, these flasks are graduated in durable white enamel to show the approximate capacity and have an extra large marking spot. They require a No. 10 rubber stopper for sealing. Their uniform wall thickness provides the proper balance between mechanical str…

These 500 mL PYREX® Kjeldahl flasks have tooled finished necks for extra strength and uniform rubber stopper (No. 6) fit. Wall thickness is controlled to offer the optimum balance between thermal shock and chemical resistance. They can be used in ASTM E-258 procedures. Care must be taken to ensure the bottoms of the flasks do not come in contact with the heating elements. Most Kjeldahl equipment manufacturers have ring support…

These 500 mL Class A PYREX® volumetric flasks have machine-blown bodies to which are sealed heavy-beaded, heavy-tubing necks, tooled for No. 500 polyethylene snap-caps. For replacement snap-caps see No. 7666. The graduation line is sharp and permanent. Large white block letters make the inscription easy to read. These Class A volumetric flasks have been manufactured to Class A tolerances as established by ASTM E- 694 for volum…

These 1L Class A PYREX® mixing volumetric flasks have an upper bulb, located between the Standard Taper stopper and the capacity graduation to assist in the mixing of liquids or powders when shaken. This bulb is approximately one-tenth the flask rated capacity of the flask. The strength of these flasks has been increased appreciably through machine-blown bodies to which are sealed heavy-tubing necks tooled for No. 22 Standard…

The Corning LSE Low Speed Orbital Shaker includes a 30 x 30 cm platform and is ideal for staining and destaining gels, washing blots and general mixing applications. Speed can be set from 3 to 60 rpm and the timer can be set for up to 2 hours or for continuous operation.Ideal for staining and washing of fragile gelsGentle motion prevents foaming of liquidsSimple analog control with easy-turn knobs19mm orbit for blotting, gel s…

The Corning LSE Digital Microplate Shaker features digital control of shaking speed and run time. A single control knob is used to set parameters, and values are shown on a large 3-digit display. A sturdy base encloses the motor for quiet, vibration-free operation. The included stainless steel platform accommodates up to 4 microplates (standard or deep well) and the shaker is safe for use in temperature controlled environments…

These reusable 10 mL PYREX® serological pipets are designed for cotton plugging. The uniform top-end openings permit performing of plugs and allow precise control of liquid column. Color-coded by size for easy identification and sorting. Colored graduations are enameled onto the glass. The two rings indicate the pipet is calibrated (TD) its total capacity when the last drop is blown out. Reference: ASTM E-1044.

These hand-driven 15 mL PYREX®; tissue grinders are supplied with two pestles to ensure dissociation of cells into fine particles with minimal damage to cell nuclei. Particularly useful in enzyme studies where heat build-up must be avoided. The internal diameter at the bottom of the unground glass tube (mortar) is .6000 inches Use the large clearance A pestle for initial reduction of soft tissue. The diameter of the ground a…

These PYREX® 14 mL test tubes are made from special tubing to give the optimum wall thickness. They are well annealed, resistant to heat and chemically stable. These 15x125mm tubes have a white marking spot. Beaded rims are fire-polished.
