Easy, accurate cell counting at about half the cost
The 4-Chip is a disposable plastic hemocytometer that builds on the popular C-Chip design. It delivers twice as many counts for nearly the same price as a 2-chamber option, helping reduce per-test costs by close to 50%.
It’s also simpler and more consistent to use. Traditional glass hemocytometers rely on a correctly seated coverslip; small fit issues can change chamber volume and introduce variability. Uncontained samples can also increase the risk of cross-contamination or exposure to infectious material.
The 4-Chip solves this with an integrated, all-in-one chamber and built-in coverslip. It includes four precision 100 µm-height counting chambers, each with a micro-etched Neubauer Improved grid. Just load 6 µL into any chamber, place it on the microscope, and start counting. When you’re done, discard it, no washing required.

Easy, precise cell counting
Looking for a disposable plastic hemocytometer that improves on traditional glass models? The 2-Chip eliminates tedious washing and helps reduce exposure risks from infectious samples and cross-contamination.
With conventional glass hemocytometers, a poor coverslip-to-chamber fit can change the effective chamber volume, leading to inconsistent counts. The 2-Chip avoids this issue with an all-in-one chamber design that includes an integrated cover.
Each 2-Chip includes two precision-engineered counting chambers (100 µm height) with no coverslips required. Simply load 10 µL into each chamber, place it on the microscope, and start counting. When you’re done, discard it. That’s it.
Note: We have renamed our popular two-chamber disposable hemocytometer from C-Chip to 2-Chip, so the packaging graphics have changed. Everything else remains the same: same product, same manufacturing facility, and the exact same specifications.

The same quality for a lower price
These electroporation cuvettes enable efficient transfer of DNA, RNA, and proteins into a wide range of cell types used with standard electroporation instruments. While cap shape and color can vary by brand, cuvettes must meet strict manufacturing tolerances to ensure consistent pulse delivery and reproducible results.
They are manufactured under contract by a partner that is ISO 9001 certified, ITAR registered, and FDA registered. Over the years, a quality assurance program has been developed to meet and exceed every measurable qualification and performance parameter. Because unnecessary markups and overhead are avoided, these cuvettes are priced at nearly half the cost of many competing brands. So we ask: why pay more for equal or inferior quality?
Universal fit
These electroporation cuvettes fit most common electroporation systems, including platforms from Bio-Rad, BTX, Lonza/Amaxa (Nucleofector II and 2b only), Invitrogen, and Eppendorf. The manufacturing partner also supports a broad range of electroporation systems (including those from Nepa Gene), demonstrating excellent performance across diverse cell types including primary cells, organoids, stem cells, marine protists, mammalian zygotes, and more.
Built for demanding applications
Electroporation is widely documented as a high-efficiency delivery method that can preserve strong viability, even in difficult or sensitive human cell lines. To achieve reliable field strength and consistent results, these cuvettes are constructed with burr-free, specially processed electrodes and virgin, medical-grade polycarbonate.
These design choices support high-performance results in demanding applications, including:
Hard-to-transfect organisms (e.g., diatoms, Chlamydomonas)
Sensitive immune cells (T cells and B cells)
Stem cells and other fragile cell types
Delivery of plasmid DNA, siRNA, and CRISPR/Cas9 reagents
Have questions? We’re happy to discuss recommended protocols and optimization approaches.
Options and sizes
Available with or without sterile transfer pipettes. Choose from three gap widths: 1 mm, 2 mm, and 4 mm (0.1 cm, 0.2 cm, and 0.4 cm). Selecting the right cuvette size for your cells is straightforward.
