Department of Agriculture or an endorsement by the Department over other products not mentioned. The possibility of overlooking bromatologka step in the procedure’is also reduced. Laboratory evaluation of forage is essentially aimed at obtaining analytical data that predict the extent of biological degradation under speci- fied conditions, animals, organisms, and time.

A unit refluxing apparatus and a drying oven bromatoologia enough to hold 80 cru- cibles make this possible. A condenser at the top of the flask prevents loss of steam. Scimatco rubber tubing, black, thick wall. Six polyethylene tubes are attached into the larger tube.
Check pH to range 6.
Experience has shown that filtration of a difficult sample niust begin with little to no vacuum and then be gradually increased. An ashing oven equip- ped with a temperature regulator to prevent the glass crucibles from melting is required for cleaning the crucibles.
Vinyl- ized clamps are used to allow for expansion of glassware due to temperature change. Filtra- tion must be individually controlled for each crucible. Rings covered with rubber tubing are placed above the hotplate to prevent knock- ing off the beaker. Apostila de bromatologia Apostila de bromatologia.

Vacuum level is controlled by attaching a rubber tube with a screw clamp to the opposite end of the poly- ethylene manifold. Figure 2 shows the complete six-unit refluxing apparatus, which requires a multielectric six-receptable box with a minimum of 20 a. Gromatologia rubber tubing con- nects from the manifold to two Apparatus In general, equipment that is used for crude fiber may be adapted to the detergent fiber pro- cedures.
An attempt has been made to cover the prin- cipal problems in technique encountered in these procedures.
It is very im. Often a very significant volume can be filtered without any vacuum.
Samples that contain appreciable amounts of. Then add CTAB and stir. Resuspend mat in water and pour into a square bag sewn from a rectangle of fiber- glass window screening of 14 x 18 mesh about 1 m.

Flexaframe hook connectors need approx- imately 36 for a set of six hotplates h. A variable transformer with a capacity of 10 a. A convenient setup is shown in figure 7.
Multielectric 6-receptacle box, 20 a. The manifold is made from large polyethylene pipe, 2 feet 60 cm. Water enters from the reservoir into the leveling device and then goes directly to the bottom of the well. The filter manifold is constructed to hold six crucibles, so that six samples can be filtered at one time. Trade names are used in this publication brkmatologia for the purpose of providing specific information.

The Y is insulated and wrapped with asbestos tape so that the hot water can be manipulated without protection for the hands. The in vitro, however, does not disclose anything re- garding the nature of the limiting factor. Other bromagologia of reflux apparatus probably are suitable if they conform to the following criteria:
