Features:
Microscale sample test: minimum sample size of 0.5 µL, with most samples requiring no dilution.
PC control: offers more accurate and flexible control via PC interface.
Dual platform (ultramicro and cuvette): available for both ultramicro and cuvette-based tests (only for BK-CW2000).
Wide test area: provides 100 times the test capacity of traditional spectrophotometers.
Instant test: can test samples immediately without the need for warm-up.
No detection container required: reduces consumable costs by eliminating the need for a separate detection container.
Lower daily consumption: designed for cost-effective daily use.
