Labware and Lab Supplies Products & Reviews

These 5L PYREX® heavy duty boiling flasks provide increased mechanical strength. The flask features walls which are 25-30% thicker than the standard version. O.D. dimensions have not been changed. They have full length outer 45/50 Standard Taper joints, but with shorter necks. The normal working temperature for PYREX® boiling flasks is 230°C. Adapter Nos. 8800, 8820 and 8825 are used to connect flasks with different size joint…

With full length joints, but with short necks.The 100, 250, and 500 mL flasks are replacement parts for organic chemistry kits (Cat. Nos. 6949 through 6949K).

These 100 mL PYREX® round bottom boiling flasks have full length outer 14/20 Standard Taper joints, but with shorter 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…

These 50 mL PYREX® long neck shaker culture flasks are basically Erlenmeyer flasks to which a long straight, rimless neck of heavy tubing has been added. The longer necks reduce the amount of splashed solution reaching the closure. They are ideal for shaker cultures. Their uniform wall thickness provides the proper balance between mechanical strength and thermal shock resistance. For convenience, these flasks include a marking…

These 125 mL PYREX® Delong style shaker flasks have three baffle indents designed to provide greater agitation of solutions to improve oxygen or gas transfer when used with rotary or reciprocating shakers. The long neck reduces splashing and is designed for two-position polypropylene closures. Their uniform wall thickness provides the proper balance between mechanical strength and thermal shock resistance. For convenience, the…

Delong style neck, with three extra-deep baffles, to enhance gas transfer when used with rotary or reciprocating shakers. Long neck reduces splashing and is designed for two-position poly­propylene closures. Closures are sold separately.

These 125 mL PYREX® Erlenmeyer flasks have heavy tooled rims for maximum durability. The same baffle design as found on PYREX® Delong flasks promotes optimal and consistent solution agitation when used with flask shakers. Their uniform wall thickness provides the proper balance between mechanical strength and thermal shock resistance. For convenience, these flasks include a marking spot.

These 1.5L PYREX® trypsinizing flasks are used for converting homogenous tissue samples into cell suspensions by digestion of connective proteins. Heavy beaded neck accepts cotton plugs. Four extra-deep baffles enhance vigorous agitation.
