PP & PC Desiccators – FAQs:
Q1. What are PP and PC Desiccators?
PP (Polypropylene) desiccators and PC (Polycarbonate) desiccators are laboratory storage chambers designed to keep samples, chemicals, and hygroscopic materials moisture-free. They use desiccants like silica gel to maintain a dry environment. PC desiccators are transparent for visibility, while PP desiccators are opaque and highly chemical resistant.
Q2. What are the uses of Laboratory Desiccators?
Laboratory desiccators are used for:
- Storing moisture-sensitive chemicals and reagents.
- Protecting hygroscopic samples from humidity.
- Cooling crucibles, weighing samples after heating.
- Ensuring long-term storage of dry laboratory materials.
Q3. What is the difference between PP and PC Desiccators?
| Feature |
PP Desiccators (Polypropylene) |

Q4. Are PP & PC Desiccators autoclavable?
- PP Desiccators – Yes ✅, they can be autoclaved at 121°C, making them suitable for sterile environments.
- PC Desiccators – Limited autoclavability (may deform with repeated cycles). Best for applications where visibility is important.
Q5. Do PP & PC Desiccators come with vacuum options?
Yes, both PP desiccators and PC desiccators are available in standard (non-vacuum) and vacuum desiccator models, allowing faster and more effective removal of moisture from samples.
Q6. What sizes are PP & PC Desiccators available in?
Desiccators are available in multiple sizes such as:
-
150 mm, 200 mm, 250 mm, 300 mm, 350 mm diameter (and larger, depending on requirement).
Q7. Which is better: PP or PC Desiccators?
- Choose PP Desiccators if you need chemical resistance and cost-effectiveness.
- Choose PC Desiccators if you need clear visibility and strength.
For sterile and heavy-duty laboratory applications, PP autoclavable desiccators are often preferred.
Q8. Where to buy high-quality PP & PC Desiccators in India?
You can buy PP desiccators, PC desiccators, vacuum desiccators, and autoclavable laboratory desiccators from trusted manufacturers, suppliers, and exporters in India. For premium-quality desiccators, Simson Chemtech is a reliable manufacturer and supplier in India.
