Hemocytometer Cell Counting Helper Pack

Our Hemocytometer Cell Counting Helper Pack includes three printable and digital tools for cell counting. You get a Reference Card to pin above the microscope, a Log Sheet to record raw counts in your notebook, and a Calculator spreadsheet to do the maths.

Built from our foundational Bitesize Bio cell counting guide and refined with the practitioner-tested ranges, counting rules, and quality flags that the protocol books leave out. Use it for every cell line, every passage, every seeding calculation.

• Apply the formula with a worked example, square-pattern decision rule, and acceptable ranges for every count you run
• Record raw counts at the microscope on a 23-row log sheet you tape straight into your lab book
• Calculate cells/mL automatically with a spreadsheet that flags counts outside the 20–60 cells per square target
• Solve the reverse problem by entering a target cell number to get the exact volume you need to pipette
