A 10000 ml low-form beaker made of borosilicate 3.3 glass with a spout and graduations. Used for solution preparation, mixing, heating and large-volume sample work. The volume marks are approximate; use a graduated cylinder or volumetric flask for precise measurement.

A borosilicate glass Erlenmeyer flask with a ground-joint neck. Used for solution preparation, titration, heating and mixing, together with ground stoppers or glass setups. Volume marks are approximate; use a graduated cylinder or volumetric flask for precise measurement. Available in 25 ml, 3000 ml and 5000 ml.

A side-arm glass filtering flask used with Büchner funnels and filter crucibles in vacuum filtration setups. The side arm connects to the vacuum line. Because it is used under vacuum, never use cracked, scratched or damaged flasks. Available in 5000 ml and 10000 ml.

A long-stem Por. 3 filter funnel made of Boro 3.3 borosilicate glass with a sintered glass filter. Used for filtering solids from solutions and in applications such as gas dispersion. The Por. number indicates the pore size.

An amber, narrow-mouth glass bottle used to store light-sensitive solutions, reagents and samples. Amber glass helps protect light-sensitive contents. Available in 250 ml, 500 ml and 1000 ml.

A metal ring holder with a clamp head that attaches to laboratory stands to support funnels, separatory funnels and similar glassware. It is fixed to the stand rod at the desired height with its screw fastening.

A Por. 1 filter crucible with a sintered glass filter at its base, used in vacuum filtration to separate solids from liquids. The Por. number indicates the pore size. Clean with a suitable solvent after use and avoid contact of the filter surface with hard objects.

A wide-angle bend adapter with ground joints at both ends, used to change the connection direction in glass setups. The joint size (NS) must match the glassware to be connected. Choose the NS size you need from the product options.

A glass desiccator with a stopcock vacuum connection on the lid, used to store and dry samples, chemicals and hygroscopic materials away from moisture. The lid and body join with a ground rim; applying vacuum increases the drying effect. Place a desiccant in the lower compartment and the samples on the plate. As a glass product, protect it from impact and sudden temperature changes.
