- Use separate culture media at the same time to determine bacterial and fungal counts
- 100 or 200 liter per minute formats, contact plate or Petri plate formats
- Charges via cable; Sample up to 70,000 liters on a single battery charge
- Programmable options include up to 100 place IDs and 100 Operator IDs
Trio.Bas™ AIRBIO DUO Kit Contains:
- Instrument
- Two stainless steel aspirating heads
