KIMAX jar useful for filtrations where it is desirable to collect filtrate in a crucible, beaker or flask for further work. May be used with either common chemical funnels or fritted ware. Larger size will accommodate a 250 mL Erlenmeyer flask. Bottom of the flange is ground, so that a seal may be made with a piece of ground flat glass. Flat glass is not supplied. Tooled hose connection is designed to accept 5/16 inch I.D. flexible tubing.
Filtraters quickly and simply, 3 times faster than the gravity method.
Filtrate is collected directly in a beaker, eliminating transfers.
Filter domes are constructed of borosilicate glass and polypropylene. Chances of trace metal contamination are virtually eliminated. Designed for direct filtration and for use where transfers should be avoided. Filter domes are recommended for EPA-type sample digestions prior to Atomic Absorption Spectroscopy. Several units may be connected in a series and vacuum applied from a single source. The upper portion of the dome is tooled to accept a No. 8 stopper and the popular 47 and 90 mm funnel/support filtration assemblies. Valve and hose connections are made of CTFE. O-rings are Viton®.
(25) KIMAX funnel used wherever filter paper and membranes cannot withstand the chemical attack of the filtrate. Funnels are constructed with heavy-walled stems, and top rims are beaded for extra strength. With a marking spot. Designed from Federal Specification DD-F-776.
(8) Useful where a support is required for either a paper or polymeric filter. Not for applications where pressure would exceed 15 psi. Sintered glass fritted disc is sealed in. Available in three porosities: Fine (F), Medium (M) and Coarse (C).
(31) Funnel with sealed-in fritted disc and an integral #2 side hose connection. Useful with paper or polymeric filters. Not recommended for use above 15 psi.
(7) Conical funnel shape directs filtrate through a reduced area frit to concentrate crystal residue for rewashing. Available in three porosities: Fine (F), Medium (M) and Coarse (C).
KIMAX pump designed for minimum free air flow of 6.5 liters per minute with 40 lbs. of water pressure. With the same water pressure, a 500 mL filter flask is evacuated to the vapor pressure of water (approximately 29.3" of mercury vacuum) in approximately 1.5 minutes. Since water backs up into all pumps tested when operated on a closed system at pressures of less than 35 lbs., a check valve of improved design is an integral part of this pump. Stems are designed to accept 5/16 inch I.D. flexible tubing.
A container used in the formation of a precipitate. Slight pressure or vacuum can be used to speed filtration. 1/4" O.D. sidearm has a sealed-in fritted disc.
