Deep-well plate system, Riplate® medio
Screening, sample storage et al. Ritter Riplate® systems are in line with the SBS-standard and are suitalbe for automation systems with corresponding closing- and sealing-mechanism.Due to the compact construction of Riplate® medio less than 50 % stacking size is needed. Higher well rims allow an airtight closure or sealing of Riplate® medio. The alphanumeric marking allows registration and identification of single assays.

Deep-well plate system, Riplate® round wells
Screening, sample storage et al. Ritter Riplate® systems are in line with the SBS-standard and are suitalbe for automation systems with corresponding closing- and sealing-mechanism.Raised wells reduce the risk of cross-contamination and increase the security of hot sealing or sealing with adhesive foils. Riplate® 1ml is ideal for use in a thermocycler or for defrosting of samples in a hot-water bath. The U-shaped well bottom reduces the death-volume.

Deep-well plate system, Riplate® square wells
Screening, sample storage et al. Ritter Riplate® systems are in line with the SBS-standard and are suitalbe for automation systems with corresponding closing- and sealing-mechanism.Riplate® SW have been developed for optimal use of capacity when it comes to sample storage. Due to the SBS-format the outside dimensions of Riplate® are given. Form follows function: the construction of cavities is crucial for a maximum absorption of liquids.
