Two-Chamber McMaster Counting Slides

Made of clear durable acrylic for long-lasting use, our slides also feature exact volumes thanks to injection-molded accuracy which yield consistent test results compared to other slides with handmade chamber spacers.  The quality of these slides make them the standard the world over. Each slide is bonded by hand with high quality materials. Some clouding and bubbling where the slide is bonded is perfectly normal and does not affect the efficacy of each slide. This type of bonding method makes each slide the strongest on the market.
