FAQ for Portable Colony Spreader NPCS-100
1: Can the Portable Colony Spreader NPCS-100 accommodate agar plates of various sizes, or is it limited to 90mm?
It is specifically designed and optimized for use with 90mm plates to ensure precise and uniform spreading. While smaller plates might fit, optimal results are guaranteed only with the recommended size.
2: What is the typical maximum volume of microbial culture that can be efficiently spread using this device?
The Portable Colony Spreader NPCS-100 efficiently spreads microbial cultures typically ranging from 50 to 500 microliters (µL). Spreading volumes significantly outside this range may affect uniformity.
3: How frequently should the sterilizable disc be cleaned, and what are the recommended sterilization methods?
The sterilizable disc should be cleaned and sterilized before each new set of experiments via autoclaving or thorough disinfection with a suitable laboratory disinfectant to prevent cross-contamination.
4: Does simple maintenance imply internal servicing is not required, or are there specific user tasks for the motor?
Simple maintenance refers to easy cleaning of the disc and exterior; the internal motor and components are sealed and do not require routine user servicing. Deeper issues should be addressed by qualified technicians.
5: Is the Portable Colony Spreader NPCS-100 capable of battery operation for use in locations without direct power access?
No, it operates strictly on AC 220V ± 22V, 50Hz ± 1Hz electric power. It does not have an internal battery and requires a standard wall outlet connection.
6: What is the purpose of using a colony spreader in microbiology?
It ensures the even distribution of microbial cultures on agar plates, promoting uniform colony formation for accurate analysis and comparison.
7: Can colony spreaders be autoclaved for sterilization?
Yes, most stainless steel and some plastic spreaders are fully autoclavable, making them reusable and contamination-free for lab use.
8: Is there a preferred technique when using a colony spreader?
Yes, a gentle circular or zigzag motion is recommended to ensure even distribution without damaging the agar surface or clumping the inoculum.
9: Is the colony spreader suitable for quantitative microbial testing?
Yes, when used with standardized inoculum volumes, colony spreaders support precise plating techniques required for quantitative microbial analysis.
Colony Spreader is used to distribute microbial suspensions evenly on agar surfaces in Petri dishes. They ensure consistent colony growth by enabling smooth and uniform spreading. These tools are available in different materials and formats to suit various lab protocols. Our design simplicity and efficiency make it essential in microbiology and clinical labs. This is designed for safe handling and delivers reliable performance across repeated plating procedures.
