Applications and Experiments for the Capillary Tube Sealant
Before a filled capillary goes into a centrifuge, one end must be closed so that the blood is not thrown out as the rotor spins. The dry end of the tube is pressed into the sealant to form a plug, and the sealed tube is then stood in one of the 24 tray slots until it is loaded.
- DMLT and B.Sc. MLT haematology: sealing heparinised or EDTA capillaries for micro-haematocrit (packed cell volume) runs.
- Clinical laboratory training: organising up to 24 sealed capillaries in the tray before centrifugation.
- Bench safety practice: handling capillaries in Gloves W/o Powder Nitrile Disposable and placing broken glass in a Sharp Container Leak Proof Plastic.
Press each capillary in vertically and check that the plug is complete before the tube goes into the centrifuge.
Standard Scope of Supply
The Capillary Tube Sealant is supplied as the sealant together with its 24-slot tray for holding capillary tubes, as described in the table. Capillary tubes, lancets and a haematocrit centrifuge are separate products, and each of them can be added to the same quotation.
Packing, MOQ and Lead Time
One sealant set may be enough for a single haematocrit bench, while a training centre with several benches may want more. Ask for a quotation for the number you need, and Science Lab Supplies will state the packing, delivery time and price, with capillaries or a centrifuge added if required.
Having an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Bangladesh, Zambia, Rwanda, South Africa, Qatar and Sri Lanka. Sealant enquiries can be posted through the contact page or collected in the enquiry cart, with formal procurement routed via the lab tender page.
Frequently Asked Questions
What is the Capillary Tube Sealant used for?
It is used to seal capillary tubes before centrifugation. Closing one end of the filled tube keeps the sample inside while the centrifuge spins, which is a required step in micro-haematocrit work.
How many tubes does the tray hold?
The tray has 24 slots for holding capillary tubes. Sealed tubes can stand in the slots in order, which helps keep each sample identified until it is loaded into the centrifuge.
Which capillary tubes can be sealed with it?
It is a sealant for capillary tubes in general. Before ordering, compare the outside diameter of your capillaries with the tray slots; send the tube size through the contact page if you need us to confirm it on the quotation.
Who supplies the Capillary Tube Sealant?
This sealant is supplied by Science Lab Supplies from Ambala, India, which quotes it for laboratories, medical training colleges and distributors and can add capillary tubes, lancets and a haematocrit centrifuge to make up a complete bench.
