When should I choose the 4L-80 over the 4L-60?
The −85 °C condenser of the 4L-80 is recommended for samples with very low collapse temperatures (Tc) such as sucrose-based formulations, mRNA preparations, and heat-sensitive proteins.
Is the vacuum pump included?
The Pioneer 4L is supplied with a 2XZ-2 rotary vane pump (2 L/s). An oil-free DRV-10 pump is available as an upgrade for contamination-sensitive samples.
Can I upgrade from the 4L-60 to the 4L-80 later?
No — the condenser and compressor are fixed at manufacture. Choose the condenser temperature based on your most demanding application.
