Lithium Heparin Membrane Drying Tunnel Oven is a continuous, high-precision thermal processing equipment specially designed for the medical, in vitro diagnostics (IVD), and special materials industries. It is mainly used for high-efficiency drying and curing of membranes, test strips, substrates, or blood collection tube-related components coated with lithium heparin (a commonly used anticoagulant). The following is a detailed analysis of this equipment:

Application

Medical and In Vitro Diagnostics (IVD)

Used for the rapid drying of anticoagulant membranes, anticoagulant blocks, or coatings in vacuum blood collection tubes (lithium heparin anticoagulant tubes).

Biochips and Biochemical Test Strips

Used for drying bioactive coatings on POCT (Point-of-Care Testing) test strips.

High-Precision Coating Materials

Applicable to other thin-film materials requiring precise temperature control, dust-free conditions, and non-damaging surface coating treatment.

Standards

GMP / FDA Regulations

Complies with pharmaceutical and medical device production quality management requirements for medical-grade equipment.

YY/T 0314 / ISO 6710

Applicable standards related to in vitro blood collection tubes, ensuring that lithium heparin activity remains unaffected after the drying process.

GB/T 30435 / GB 4793.1

Relevant safety standards for industrial thermal testing equipment, measurement and control equipment, and electrical equipment for laboratory use.

Cleanliness Standards

The equipment usually needs to meet ISO Class 5 (Class 100) or ISO Class 6 (Class 1000) air cleanliness requirements.

Features

Precise Temperature Control and High Uniformity

The system adopts multi-zone independent microcomputer temperature control, with extremely small temperature differences (usually within ±1°C), preventing lithium heparin deactivation caused by local overheating.

Clean and Dust-Free Design

The internal structure is made of stainless steel and equipped with high-efficiency filters (HEPA) to prevent secondary contamination of the membranes.

High-Efficiency Continuous Operation

The tunnel conveyor structure enables integrated continuous production, including feeding, drying, cooling, and unloading processes.

Gentle Drying Technology

The equipment mainly adopts infrared heating, hot air circulation, or a combination of low-vacuum drying technology to achieve rapid non-contact evaporation of moisture or solvents.
