Description
Sponges for embedding frames are thin blue foam inserts used to secure and cushion tissue specimens inside embedding frames during paraffin processing. Each sponge measures 32 x 26 x 2,5 mm, fitting the working area of standard embedding frames so samples remain gently held while medium solidifies. The blue foam construction makes the pads easy to spot during cassette loading and helps prevent specimen displacement or crushing in high-throughput histology. Supplied by manufacturer Witeg as a matched accessory for embedding frames, these sponges support consistent orientation of small biopsies and delicate samples before microtomy. Pack size is 500 pieces, providing an economical stock for pathology and research laboratories that process many blocks per day. Net weight is only 0,026 kg per pack, so storage and restocking remain simple. Ideal for routine paraffin embedding workflows where foam pads improve specimen stability inside plastic or metal embedding frames.
This article is part of Test sieves (wire mesh), in Test sieves & mills.

Questions about Sponges for Embedding frames
What is this article?
Sponges for Embedding frames is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Test sieves (wire mesh), inside Test sieves & mills, in Lab instruments.
A wire-mesh test sieve sorts particles through a woven opening of a stated nominal size. The frame diameter and the mesh are the specification. A sieve without a certificate is a screen, not a measurement.
A test sieve sorts particles by whether they pass an opening. Wire mesh and perforated plate are two ways of making that opening, and the nominal size is not a suggestion. A sieve shaker repeats the motion so the result does not depend on how hard someone shook by hand. A mill or grinder makes the particles smaller before they are sieved. The certificate of the sieve, and the opening size, are what an audit asks for. Measurement practice around mass and dimension sits with the BIPM, EURAMET and BELAC.
Which category should I open next?
The category is Test sieves & mills. The sub-category is Test sieves (wire mesh). The catalogue is Lab instruments.
Shelves beside this one are Test sieves (perforated plate), Mills, grinders & homogenisers, Sieve shakers and Sieve accessories (lids, pans, rings).
What should I check before I order?
