Photo of Corning 7086 PYREX® Reusable Color-Coded TD Serological Pipets for Cotton Plugging with Colored Markings

These reusable 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 "to deliver" (TD) its total capacity when the last drop is blown out. Reference: ASTM E-1044.

These reusable PYREX® pipets are calibrated to Class A tolerances in accordance with ASTM E-542, and ASTM E-1293. Each pipet is individually serialized and supplied with a Certificate of Identification and Capacity, traceable to NIST standards. Calibrated "to deliver" (TD) their total capacity without blow-out. Color-coded by size for easy identification. Colored graduations are enameled onto the glass. The top end of 5 to 25mL sizes is constricted (Mohr type). Now tested and calibrated in an ISO/IEC 17025 certified laboratory.

These precision PYREX® blood chemistry pipets meet or exceed specifications for Class A volumetric ware as indicated by ASTM E-969. Shorter, and more compact than a Class A volumetric pipet, these pipets were originally suggested by Folin for use in determining total nitrogen, urea and ammonia in urine; they are now generally used for blood serum tests. They are calibrated "to deliver" (TD) by blowing out the last drop. Colored graduations are enameled onto the glass.

These Corning® disposable glass Pasteur pipets are available in convenient bulk-packs. One-time use eliminates the danger of cross-contamination of valuable specimens or laboratory reagents. These pipets feature a constriction one inch below the top to facilitate plugging. They are ideal for rapid nonvolumetric transfer work in bacteriology, immunology, hematology and serology studies, as well as blood bank and clinical chemistry procedures. These "B" series pipets are made from soda lime glass.

Photo of Corning 7058 PYREX® Graduated Disposable Bacteriological Pipets, Sterile and Plugged

These PYREX® borosilicate glass pipets meet the requirements recommended by the American Public Health Association as shown in "Standard Methods for the Examination of Dairy Products." This pipet is very convenient when duplicate platings are to be made on the same medium or for plating differential medium for the determination of gram-negative bacteria, mold and yeast, or total plate count. Both sizes are designed for gravity feed (blow-out is not required). These cotton-plugged pipets are packaged in sterile bags.

These Corning® stirrers with the glass-ceramic Pyroceram® top have digital stirring speed displays. Exclusive closed-loop stirring control monitors and regulates the stirring speed from 60-1150 RPM for aqueous, viscous, or semi-solid solutions. Digital LED speed display gives you better control of your stirring process. Stronger, larger magnet improves stir bar coupling combined with automatic ramp up speed adjustment minimizes decoupling. Two piece casting design deflects spills away from electronics and includes a built in mount for an optional 18" (45.7cm) support rod (Cat. No. 440129).

These PYREX® straight bore stopcocks have a PS taper PTFE plug that fits into a micro-finish barrel. Freezing problems are reduced and greasing is eliminated. The very fine threads on the plug and nut let you "feel" the position of the plug. Sidearm seals are heavy and strong for greater durability and easier handling.

Photo of Corning 7473 PYREX® Plain Bore Rotaflo® Two-Way 90° Angle Stopcocks

These high performance Rotaflo® 90° angle stopcocks are designed so that only chemically resistant polytetrafluoroethylene (PTFE) and PYREX® borosilicate glass are in contact with liquids and gases. The Rotaflo® stopcock design permits fine flow adjustment. Lubrication is not required and assembly is fast because there are no O-rings, washers or nuts. The seal is visible when open or closed.

Photo of Corning 7680 PYREX® Replacement Standard Taper Straight Bore Glass Stopcock Plugs

These are replacement glass stopcock plugs for No. 7280 PYREX® straight bore glass stopcocks. Since several different bored sizes may be drilled through any given size of plug, the approved method of designating the size of a glass stopcock is by bore diameter only. Interchangeable ground glass stopcocks are not intended for high vacuum apparatus or for use with light liquids. When, by constant abrasion, a stopcock has become so worn that the shell is enlarged, or the plug is diminished in size, we recommend that you replace the plug.

Photo of Corning 7624 PYREX® Polyethylene Standard Taper Stoppers

These blue and white PYREX® stoppers are made from linear high-density polyethylene and have closed bottoms to conform to Standard Taper stopper dimensions. The three rings on the plug provide an efficient seal. This improved design fully protects the neck in the event of accidental tipping. These stoppers may be used in place of the conventional glass Standard Taper flask stoppers.

These hollow full length PYREX® Standard Taper joint stoppers are closed at the bottom. They are interchangeable with standard taper joints of the same size. These hollow stoppers are light in weight, yet very strong to reduce chipping and breakage, thus minimizing replacement costs. A barrel-shaped head means it is easy to clean and even easier to rotate in or out. Grooves in the sides help prevent slippage. The flat top allows the stopper to stand on its head, which frees the user's hand and minimizes potential contamination.

Photo of Corning 9825 PYREX® Reuseable Screw Cap Culture Tubes with Phenolic Caps

These PYREX® culture tubes are supplied with deep-form phenolic caps to facilitate handling and sealing after autoclaving. Caps are fabricated from a special formula resistant to the effects of temperature and steam in autoclaving and are provided with a glued-in, white rubber liner. The white enamel marking spot gives an excellent surface for pencil notations. Pencil marks are easily erased. For replacement phenolic caps, see No. 9999.
