Vacuum Tube, Plain/Dry
Vacuum Tube, Plain/Dry (Product Code: SLE/CL/38) is a 6ml evacuated PET blood collection tube without anticoagulant, used to collect venous blood that is left to clot so serum can be separated for testing. Its vacuum-sealed cap draws blood once connected to a venipuncture needle, which makes it a routine item at phlebotomy counters, hospital laboratories and medical laboratory training rooms. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as part of its disposable lab equipment range in India.

What Is the Plain Vacuum Tube Used For?
A plain tube is chosen when the laboratory needs clotted blood, most often so that serum can be separated for biochemistry or serology work. After the draw, the tube is stood upright and left undisturbed until a firm clot forms; it is then centrifuged and the clear serum above the clot is transferred with a pipette for testing. Because nothing has been added to the tube, there is no additive to mix in, and in a multi-tube draw plain tubes are normally filled before additive tubes such as EDTA so that no anticoagulant is carried over.
Keep unopened stock between 2 °C and 30 °C, label each tube immediately after filling, and set aside any tube that does not draw blood, as its vacuum may have been lost. Training institutes that order from a lab consumables supplier in India often stock plain, serum gel and EDTA tubes together so students can practise the complete venous sampling sequence.

Frequently Asked Questions
Does the Vacuum Tube, Plain/Dry contain an anticoagulant?
No. The Vacuum Tube, Plain/Dry is a tube without anticoagulant, so blood collected in it clots naturally. No other additive is listed, which is why it is chosen when the laboratory needs clotted blood and serum.
What is the capacity of the plain vacuum tube?
The plain vacuum tube has a listed capacity of 6ml and is made of PET plastic with a vacuum-seal cap. If your protocol calls for a different draw volume, ask us through the contact page which other tubes can be offered.
How should unused plain vacuum tubes be stored?
Unused Vacuum Tube, Plain/Dry stock should be kept between 2 °C and 30 °C, as the listing states. No expiry period is given here; ask us for the expiry date of the batch you are quoted before dispatch.
Can the plain tube sample be used for serum tests?
Yes, serum testing is the usual purpose of the plain vacuum tube: once the blood has clotted and been centrifuged, serum is separated for testing. Each laboratory should still confirm that the tube suits its own assay methods.
Who supplies the Vacuum Tube, Plain/Dry?
The Vacuum Tube, Plain/Dry is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India. Hospitals, diagnostic laboratories, health programmes and training institutes in India and international markets can order it with other blood-collection consumables.
How many plain vacuum tubes come in a pack?
