Description
Haematocrit sealing wax consists of a vinyl plastic putty mounted on a plastic plate, specifically intended for sealing the ends of micro-haematocrit capillaries. This laboratory accessory enables secure closure of capillary tubes filled with blood samples prior to centrifugation, ensuring that the contents remain contained for precise measurement of haematocrit values. The putty provides a firm yet workable seal that withstands the forces encountered during high-speed spinning in haematocrit centrifuges. Presented as a pack of 6 pieces, it allows laboratories to maintain an adequate supply for daily operations in clinical diagnostics or research settings. From manufacturer Witeg, this sealing wax supports standardised haematology protocols where reliable capillary sealing is critical to avoid sample loss or air introduction. Application involves pressing the capillary end into the putty to form an impermeable barrier. The plastic plate base keeps the material organised and ready for repeated use across multiple tubes. Suitable for various micro-haematocrit procedures, it helps achieve consistent results in packed cell volume analysis by preserving sample integrity from preparation through to reading under routine laboratory conditions.

Questions about Hematocrit-sealing wax
What is this article?
Hematocrit-sealing wax is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Lids & seals, inside Stoppers, caps & closures, in Labware.
Lids and seals are the covers of dishes, jars and tanks: a snap lid, a sealing film, a gasket. The seal is doing the work. A lid that only rests on the rim does not contain a volatile liquid.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
Which category should I open next?
The category is Stoppers, caps & closures. The sub-category is Lids & seals. The catalogue is Labware.
Shelves beside this one are Screw caps & closures, Rubber & silicone stoppers, Ground-joint glass stoppers and Closures (other).
