1.0 mL Polypropylene K₃EDTA Blood Collection Tubes (10×45 mm) – 3K200PP

High-Performance Micro Tubes for EDTA Blood Sampling

The 3K200PP is a 1.0 mL blood collection tube made from durable polypropylene, treated with K₃EDTA anticoagulant. With external dimensions of 10×45 mm, these tubes provide small-volume precision and excellent chemical stability. The screw cap features a pink O-ring seal to help maintain sample integrity during storage or transport.

Key Features

• Volume capacity: 1.0 mL — ideal for small sample draws, paediatric use, or micro assays.

• Anticoagulant: K₃EDTA (dried form) — prevents coagulation immediately, allowing accurate hematological or cytological analysis.

• Material: Polypropylene — offers high chemical resistance and durability, especially when compared to polystyrene.

• Dimensions: 10×45 mm external — fits mini racks, centrifuge rotors, or storage holders.

• Cap type & seal: Pink O-ring screw cap ensures tight sealing to reduce risk of leaks or sample evaporation.

• Temperature range: −40 °C up to +135 °C — supports freezing and heat sterilisation / autoclaving (depending on lab setup).

• Centrifuge force: Rated up to ~17,000 g — suitable for high-speed centrifugation in many laboratory protocols.

• Anticoagulant amount: ~1.75 mg K₃EDTA per mL of blood — in line with expected standard ratios.

• Packaged & stored in foam trays for ease of handling and to minimise sample damage during shipping.

Advantages of Polypropylene Over Polystyrene

Polypropylene tubes like the 3K200PP offer greater resistance to temperature extremes and many chemicals, making them more versatile for diverse laboratory uses. The higher RCF rating also means more flexibility in centrifugation protocols. If you’re using harsh reagents, freezing, or autoclaving, polypropylene is typically the better choice.

Applications

• Routine haematology testing (full blood counts, differential counts)

• Paediatric, neonatal, or microvolume sample collection

• Clinical diagnostics and pathology labs

• Sample storage under freezing or higher temperature conditions

• Research labs using high-speed centrifugation
