Capillary Heparin Tube
Product Code : LSK-CL-11251
Capillary Heparin Tube (SKU LSK-CL-11251) is a heparin-coated capillary glass tube, 75 mm long with an inner diameter of 1.15 mm, packed in glass boxes of 100 tubes. It is intended for multiple tests on small capillary blood samples and suits haematology practicals, including packed cell volume work, in DMLT, B.Sc. MLT and nursing courses. Laboratories, colleges, tender contractors and distributors can obtain boxes from Science Lab Supplies, which handles dispatch from Ambala, India.
Specifications
The heparinised glass capillary is specified line by line in the table. Its defining points are a glass tube of 75 mm, an inner diameter of 1.15 mm and a heparin coating, with 100 tubes packed in each glass box for use in multiple laboratory tests.

Applications and Experiments for the Heparin Capillary Tube
Blood from a skin puncture is drawn into the 1.15 mm bore by capillary action, and the heparin lining prevents it from clotting inside the glass. One end is then closed with sealant, and the filled tube can be spun or examined, which makes it a convenient vessel for tests on a few drops of blood.
- DMLT and B.Sc. MLT haematology: micro-haematocrit (packed cell volume) determination on capillary blood.
- Phlebotomy and nursing training: capillary puncture technique and safe disposal of lancets in a Sharp Container Leak Proof Plastic.
- General handling practice for glass capillaries while wearing Gloves Exam Latex Without Powder.
These are glass tubes: handle them carefully, and discard any broken capillary straight into a sharps container rather than an open bin.
Standard Scope of Supply
Supply is by the glass box, each containing 100 heparin-coated capillary glass tubes of 75 mm with a 1.15 mm inner diameter. Sealant trays, lancets and a haematocrit centrifuge are separate products, and any of them can appear on the same quotation as the boxes.
Packing, MOQ and Lead Time
Request a quotation by the number of boxes of 100 you need, from one box for a teaching demonstration to several for a full training year. Science Lab Supplies specifies the packing, delivery time and price for that number, and sealant or a centrifuge can be quoted alongside.
Backed by an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in the Philippines, Nepal, Bangladesh, Zambia, Rwanda and South Africa. Box counts and delivery details can be shared on the contact page or listed in the enquiry cart; a tender purchase can follow the lab tender page.
Frequently Asked Questions
What size is the Capillary Heparin Tube?
Each capillary glass tube is 75 mm long with an inner diameter of 1.15 mm. The tubes are heparin coated and packed in glass boxes of 100, ready for small-volume blood work.
Why are the tubes coated with heparin?
Heparin is an anticoagulant. The coating keeps the capillary blood sample from clotting inside the narrow tube, so it stays fluid for centrifugation or other tests carried out on the sample.
Is a sealant needed with these tubes?
For centrifugation, one end of each filled capillary is closed with sealant. The range includes a Capillary Tube Sealant with a 24-slot tray for holding capillary tubes, which can be added to the same quotation.
Who supplies the Capillary Heparin Tube?
Science Lab Supplies in Ambala, India, supplies these heparin capillaries by the box of 100 and quotes them for laboratories, paramedical and nursing colleges and distributors, together with sealant and centrifuges if required.
Related Micro-Haematocrit and Capillary Items
A micro-haematocrit bench needs lancets, capillaries, a sealant tray and a high-speed centrifuge, and some tests call for other micro-collection formats instead. These products complete that bench, and each can be added to the same quotation as the heparin capillary tubes.
