These PYREX® tip replacements are only for the locking stopcock No. 2116-LSO.

These 125 mL PYREX® glass separatory funnels have Polytetrafluorethylene (PTFE) No. 2 Product Standard stopcocks and inner and outer 14/20 Standard Taper joints. The PTFE plug fits into the micro-finish barrel. This funnel is also a replacement for organic chemistry kit No. 6949K. The plug also reduces freezing problems and grease contamination. For PTFE stopcock plugs, see No. 7681.

These replacement 125 mL PYREX® glass separatory funnels have inner and outer 19/22 Standard Taper joints. They require Polytetrafluorethylene (PTFE) No. 2 Product Standard stopcock plug fits into the micro-finish barrel. The plug also reduces freezing problems and grease contamination. For replacement PTFE stopcock plugs, see No. 7681.

These 125 mL beakers are graduated in both fluid ounces and milliliters. The graduations are approximate only. These blown graduates, of substantial weight for greater mechanical strength, are ideal for measuring hot solutions. (Because of their heavy walls, they should not be subjected to direct contact with the heat source.)

These 1L beakers are graduated in both fluid ounces and milliliters. The graduations are approximate only. These blown graduates, of substantial weight for greater mechanical strength, are ideal for measuring hot solutions. (Because of their heavy walls, they should not be subjected to direct contact with the heat source.)

These 250 mL beakers are graduated in both fluid ounces and milliliters. The graduations are approximate only. These blown graduates, of substantial weight for greater mechanical strength, are ideal for measuring hot solutions. (Because of their heavy walls, they should not be subjected to direct contact with the heat source.)

These 2L beakers are graduated in both fluid ounces and milliliters. The graduations are approximate only. These blown graduates, of substantial weight for greater mechanical strength, are ideal for measuring hot solutions. (Because of their heavy walls, they should not be subjected to direct contact with the heat source.)

These 500 mL beakers are graduated in both fluid ounces and milliliters. The graduations are approximate only. These blown graduates, of substantial weight for greater mechanical strength, are ideal for measuring hot solutions. (Because of their heavy walls, they should not be subjected to direct contact with the heat source.)

These 1L PYREXPLUS®-coated heavy wall flasks have protective PVC coating for longer product life and safety. Protective coating helps prevent glass from shattering, reduces spills and is autoclavable (121°C) and resistant to thermal shock. For convenience, the flasks are graduated to show approximate capacity. The neck finish affords an excellent fit for rubber stoppers and uses a No. 8 rubber stopper. The 10mm tubulation is n…

Flask features a protective PVC coating for longer product life and safety. Protective coating helps prevent glass from shattering and reduces spills. Autoclavable (121°C) and resistant to thermal shock. For convenience, the flasks are graduated to show approximate capacity. Tubulation O.D. is approximately 10 mm on sizes up to 1000 mL. Tubulation O.D. is approximately 12.5 mm on 2000 and 4000 mL sizes. The tubulation is not c…
