Horizontal Laboratory Autoclave LHA-T2018

Introduction

Horizontal is a 120 L capacity Class B, microprocessor controlled automatic autoclave with vacuum drying function and steam generator. It is equipped with advanced automatic temperature recording and thermal printer with effective sterilization temperature of 139°C and 7 inch touch screen for temperature and pressure observation. With safety features like motorized interlock door system, over pressure and over temperature protection. It is ideally used for sterilizing and drying in hospitals, pharmaceutical factories, food industries, scientific research institutes, etc.

It uses high-temperature and high-pressure steam to achieve effective sterilization of laboratory equipment, media, and waste. The advanced control system ensures thorough sterilization while preventing overheating or pressure buildup.

Applications

Widely used in hospitals, pharmaceutical factories, food industries, scientific research institutes and other units to sterilize and dry clothing, dressings, metal instruments, culture medium, etc.

FAQs

1. What is the recommended sterilization cycle for different types of laboratory materials?

The recommended cycle depends on the material type: 1) For glassware and heat-resistant materials: 121°C, 15-20 psi, for 15-20 minutes; 2) For liquid media: 121°C, 15-20 psi, for 20-30 minutes (longer for larger volumes); 3) For wrapped instruments: 121°C, 15-20 psi, for 25-30 minutes to ensure steam penetration; 4) For waste materials: 132°C, 30 psi, for 30 minutes for biohazardous waste; 5) For heat-sensitive materials: Use a lower temperature (115°C) for a longer duration (30 minutes) or a specialized cycle if available. Always refer to the material manufacturer's recommendations.

2. How to properly load the autoclave to ensure effective sterilization?

Proper loading is crucial: 1) Place items in a way that allows steam to circulate freely around all surfaces; 2) Avoid overloading the autoclave chamber, leaving at least 2-3 inches of space between items; 3) Stack items with openings facing downward to prevent water accumulation and ensure steam penetration; 4) Use autoclave-compatible containers and avoid sealing them tightly (leave lids loose or use vented caps); 5) Separate different types of materials if possible, especially liquids and solids; 6) Ensure that liquid containers are not filled more than 2/3 full to prevent boiling over.

3. What maintenance procedures are required for the autoclave?

Regular maintenance includes: 1) Draining and cleaning the water reservoir after each use to prevent mineral buildup; 2) Descaling the autoclave monthly (or more frequently in hard water areas) using a recommended descaling agent; 3) Inspecting the door gasket for wear, cracks, or damage and replacing it if necessary; 4) Checking the pressure relief valve and safety interlocks quarterly to ensure proper operation; 5) Cleaning the chamber interior with a mild detergent after each use; 6) Performing annual calibration of temperature and pressure gauges by qualified personnel; 7) Keeping a maintenance log to track all service activities.

4. How to troubleshoot if the autoclave fails to reach the desired temperature or pressure?

If temperature/pressure issues occur: 1) Check if the water level in the reservoir is sufficient; 2) Verify that the door is properly closed and sealed (check gasket for damage); 3) Inspect the heating element for signs of malfunction; 4) Check the pressure relief valve to ensure it is not stuck open; 5) Clean the steam vents and drains to remove any blockages; 6) Ensure the autoclave is properly grounded and the power supply is stable; 7) If the problem persists, do not use the autoclave and contact technical support immediately, as it may pose a safety risk.

5. What safety precautions should be followed when operating the autoclave?

Important safety precautions: 1) Never open the autoclave door while it is pressurized or during the sterilization cycle; 2) Allow the autoclave to cool down and depressurize completely before opening; 3) Wear heat-resistant gloves and eye protection when handling hot items; 4) Stand to the side of the autoclave when opening the door to avoid steam burns; 5) Never autoclave incompatible materials (such as volatile solvents, oils, or explosives); 6) Regularly test the autoclave's performance using biological indicators (spore tests) to ensure effective sterilization; 7) Familiarize yourself with the emergency stop procedures and location of safety devices.
