MTC BIO
Frequently asked questions
Common questions about MTC BIO from 3G Electric.
What materials are MTC BIO cell spreaders made from?
MTC BIO cell spreaders are available in ABS and polypropylene. For example, the M5421 and M5420 models are blue ABS with a 156 mm overall height, while the M5441 is yellow polypropylene with a 235 mm overall height. The M5451 is blue polypropylene at 207 mm, and the M5430 and M5431 are blue ABS at 140 mm. Material selection affects chemical resistance and rigidity; ABS is commonly used for general spreading tasks, while polypropylene offers different chemical compatibility. Buyers should match the material to the reagents and sterilization methods used in their protocols.
What are the specifications of MTC BIO disposable cuvettes?
MTC BIO disposable cuvettes are made of polystyrene and are available in square and round shapes. The square cuvette (S4100-3) has a 1.5 mL capacity, while the round cuvette (S4100-2) has a 2.5 mL capacity. Both have a 10 mm path length and a maximum bandwidth of 800 nm, making them suitable for spectrophotometric measurements in that range. Polystyrene is not recommended for use with certain solvents; buyers should verify chemical compatibility for their specific assays. These cuvettes are designed for single-use applications.
What is the difference between MTC BIO cell spreader models M5420 and M5421?
The MTC BIO M5420 and M5421 cell spreaders are both blue ABS with a 156 mm overall height. The primary difference is the manufacturer part number and SKU; they are listed as separate items in the catalog. Both are intended for spreading cells or liquids across plates and dishes. Buyers should confirm the specific part number required for their internal tracking or protocol. No other dimensional or material differences are indicated in the available specifications.
Are MTC BIO cell spreaders suitable for CFU counting?
Yes, MTC BIO cell spreaders are used for colony-forming unit (CFU) counting. The M5441 model, for example, is specifically described as suitable for CFU count, plates, and dishes. The spreading action distributes bacterial or yeast suspensions evenly across agar surfaces, which supports consistent colony formation. The choice of spreader height and material may depend on the plate size and the volume being spread. Users should follow their laboratory's standard procedures for sterilization and handling to avoid contamination.
What applications are MTC BIO plastic cuvettes used for?
MTC BIO plastic cuvettes are used for spectrophotometric measurements up to 800 nm. They are commonly used in laboratory settings for absorbance or turbidity readings. The square and round formats fit standard spectrophotometer holders. Because they are disposable, they reduce the need for cleaning and potential cross-contamination between samples. Buyers should confirm that the cuvette material (polystyrene) is compatible with their sample solvents and that the 10 mm path length matches their instrument requirements.
How does 3G Electric support MTC BIO product selection?
3G Electric distributes MTC BIO laboratory consumables and provides specification details, part numbers, and availability information for each item. Technical buyers can request quotes for specific SKUs, and 3G Electric facilitates global shipment. The company does not manufacture MTC BIO products but serves as a source for these consumables alongside other industrial and laboratory equipment. For application-specific questions, buyers should refer to the product specifications and their own protocol requirements.
